i am more and more convinced that he only keeps me around bc i do anything he asks me to and he knows just how to get me to do it gladly...he asks me the favor, then does something affectionate or that he used to do before and when he's sure he's got me he goes back to being borderline mean towards me by flaunting how much he loves her in every single sentence

Critique as a motivation to grow
Left to right: Dan Ascherl, Adam Thomas, me, and John 00 Fleming. Photo by Robert Stainforth on my gig at Dance:Love:Hub at The Egg, London, 2017
We at JOOF have a little chatroom where we discuss and give our opinions on the incoming demos, and that is no exception to the tracks coming our own A&Rs.
So I have submitted a track which had an amazing (as I thought) acid line in the climax, and Adam who is very pedantic when it comes to 303 said: “Yeah the track is awesome and all, but your acid sounds like shit, mate”.
He surely said that in a more polite way telling me something about 18db LPF and richness of the character which I know nothing about, but one thing was clear to me: I’ve got to figure out how to improve my 303’s.
So I did. In fact, I loved that new improved acid sound so much, so one morning I woke up and completely overhauled the main lead I had in my previous track that I’ve signed a few days before (which was about to be sent to the distributor), and updated it with a new 303 sound. Kudos to Adam!
That previous track was Binary Star, and this is how it got its main acid lead that you can hear in the track now:
Binary Star will be released on November 2, and now available for pre-save on Spotify:

Coach Realtors®: Leading the Market With Stability, Strength and Savvy
No business remains a leader in its market for almost 40 years without a strong core and a sharp eye. That’s been the key to success at Long Island, N.Y.-based Coach Realtors® since the Finn family acquired the brand in 1980.
“Coach Realtors® has been in business since 1954, so we’ve witnessed market highs and lows, paradigm shifts in the industry and many, many competitors come and go,” says the company’s COO Lawrence P. (LP) Finn, III. “Through it all, we’ve grown smartly, invested wisely and built a firm that’s stable in any market and respected by an entire industry.”
Here, Finn shares how he and his leadership team have evolved the firm to weather a constantly changing real estate landscape, and remain a force locally and a thought leader industry-wide.
Maria Patterson: Please describe your firm’s history and current positioning in the marketplace. LP Finn: Coach Realtors® was founded in 1954. Larry and Georgianna Finn acquired the brand from the original owners in 1980, and they remain a guiding force for us today as chairman and president, respectively. My sister, Whitney Finn LaCosta, serves as general manager and oversees the daily activity of the branch offices, and her husband, Robert LaCosta, oversees our mortgage and title operations, Coach Title Insurance Agency, and our co-owned lending institution, Academy Mortgage Corporation. We’re all involved in any major decision-making, and our solidarity is, I think, one of the things that keeps us focused. Coach Realtors® is ranked within the top 200 brokerages in the United States in RISMedia’s Power Broker Report, consistently among the ranking’s billion-dollar producers.
MP: How many offices and agents does the firm currently have? LPF: We have 19 offices and over 650 sales associates serving over two million residents in Nassau and Suffolk Counties. We posted over $1.4 billion in sales in 2017. A large percentage of those sales were multimillion-dollar properties. We’re proud to be a market leader and a member of the finest real estate networks in the world: Christie’s International Real Estate, Leading Real Estate Companies of the World®, Mayfair International Realty, Luxury Portfolio International® and Who’s Who in Luxury Real Estate.
MP: What has been your approach to growth over the years, and what are your current goals in terms of expansion? LPF: In one word: stability. Coach Realtors® has been in business since 1954, so we’ve witnessed market highs and lows, paradigm shifts in the industry and many, many competitors come and go. Through it all, we’ve grown smartly, invested wisely and built a firm that’s stable in any market and respected by an entire industry. We’re going strong, staying true to the principles that got us here, and will continue on this path of smart growth that benefits our agents and the brand.
MP: How would you describe the current state of your market? What are the greatest challenges and opportunities? LPF: Our greatest challenge is also our greatest asset: staying true to our proven principles. Many newer brokerages, online influencers and even sales agents believe in rapid change or the adoption of new business practices. We feel that pressure to change, but we know these unproven ideas are often “one-trick ponies”—each looks good in a rising market, but they’re usually built upon sand and, therefore, lack staying power. Experience has shown us that longevity and continued success can’t happen without a commitment to our core values of financial stability, agent support, a focus on professional growth and brand recognition.
MP: What are you doing differently to set your firm and its agents apart from the competition? LPF: We differ from other brokerages in many ways. An important difference is our exclusive membership in world-class brokerage networks such as Christie’s International Real Estate. These networks provide our agents with a real advantage over other brokerages and truly unique market position. Sales agents with Coach Realtors® can provide their sellers with industry-leading property marketing and access to an exclusive pool of upper-tier buyers. Our agents also love the digital suite of services each network provides. These online tools allow an agent to rapidly grow his or her business by gaining new clients or increasing their average selling price. The networks also offer unsurpassed support, training, and, above all, brand awareness.
MP: What most attracts agents to your firm, and why do they stay? LPF: Sales associates are attracted to Coach Realtors® because of our unwavering dedication to their careers. A real estate salesperson flourishes when he or she has a strong, successful brokerage behind them—a brokerage with vision, meaningful training, great marketing support, a success-oriented company culture, and a full suite of market-leading sales tools and resources. I also cannot say enough about our management team. These talented individuals are the backbone of the Coach organization. The branch managers within Coach are amazing people filled with professionalism, integrity, caring and a desire to see the sales agents succeed.
MP: How are you helping agents stay ahead of the curve on technology? LPF: We just re-launched Coachrealtors.com. The new website offers consumers a truly wonderful online experience and also provides our agents a robust intranet. The new intranet helps agents manage all aspects of their business while automating many daily activities. There’s way too much to list here, but I can assure you that it’s really amazing!
MP: Please describe your firm’s culture and leadership philosophy. LPF: We understand that every agent at Coach Realtors® is a valuable business partner. They’re the people out there representing the Coach Realtors® brand, and we take seriously our longstanding commitment to provide them with a workplace that’s supportive, fair, friendly and fun—not to mention technically advantaged.
Coach agents showing support for The Best Week Ever (Feb. 2018)
Speaking of fun, in February of 2018, we hosted The Best Week Ever, which consisted of 18 events over five days that focused on body, mind and career. Events ranged from yoga to rock climbing, from financial planning to building listing inventory, from our awards dinner to an early morning inspiration breakfast featuring Mount Everest summiter Gary Guller. This is just one of the many reasons we have agents who have been building and sustaining successful careers with us for 20 or 30 and even 40 years.
Reaching new heights at the Coach Realtors® rock climbing event (Feb. 2018)
MP: What is your approach to coaching and training? LPF: We’re proud to provide each sales agent at Coach Realtors® with unlimited, no-cost access to Institute, powered by Leading Real Estate Companies of the World®. Institute, which is both online and mobile-device compatible, is an on-demand real estate learning center with hundreds of courses and direct access to the creative thinking of some of the top real estate minds in the industry. We cannot say enough about this comprehensive learning platform. It’s filled with engaging, role-based, just-in-time learning modules with distinct, relevant content tied to specific agent needs and objectives. Institute helps our agents to be better at every aspect of the business, whether it’s negotiation, luxury marketing, investor relations, home staging, prospecting, or effective use of social media, to name just a few. In fact, in January 2018, Training Magazine ranked LeadingRE’s Institute No. 1 among the Top 125 learning and development programs across all industries throughout the world.
MP: What are some of your most innovative marketing strategies? How are they helping you connect with consumers? LPF: Our firm’s Director of Social Media Shannon Heyman is really doing some impressive work. Social media is more than just “posting stuff” online—there’s a science to it and each action is measurable. Our social media program is reaching a large number of online users each day, and we’re seeing large-scale engagement, far above the competition. That positive engagement is driving buyers and sellers straight to Coach agents each day.
MP: What’s on deck for the future of the firm? LPF: We’ll continue to grow vertically, adding to the sales teams in each branch office as our marketshare continues to increase. To do that, we’re actively recruiting new and experienced agents who are a good fit with our company culture. We especially look for candidates with excellent people skills and the desire to learn and grow. We’re also open to timely and strategic acquisitions and to new partnerships that help us do an even better job of what we do best.

It’s a Sony. We all know their slogan and yes, they need not say anymore. Sony is a dominating and well respected name in world consumer electronics. From the Aibo to the PlayStation to the Vaio, Sony has created, innovated and excelled in the production of almost anything electronic under the sun.

In 2005, Sony car stereos launched their latest carrier car audio product, the Sony car stereo Xplod series which has an amazing lineup of head units, speakers, amplifiers, subwoofers, changers and accessories.

- 6 x 9" HOP Woofer Cone - Stroke Stabilizer Surround - 2-5/8" Cone Mid - 1" Balanced Dome PEI Tweeter, Super Tweeter - 400W Peak Power (100W RMS) - Flexible Mounting Options

Like other modern car audio manufacturers, the Sony car stereo also offers video capable units for playing VCDs, DVDs. A good item from the Sony car stereo Dream System Series is the MV - 900SDS Mobile DVD Dream System.

Best Car Amplifier for 2018
If you want great, crisp sound in your car then an amplifier is key, whether you opt for aftermarket speakers or remain with factory fitted. Obviously, replacing speakers, head units and adding subwoofers can improve sound, but without an amp you wont have enough power to drive the sound in the first place.
We have reviewed the best car amplifiers for 2018.
Car Audio Amplifier Reviews – Best 5 On The Market
Pioneer GM-D8604 Class FD 4-Channel Bridgeable Amplifier
The new Pioneer amplifier provides extreme efficiencies and clear crisp sound. The new design is compact and allows flexible installation options for the consumer. The improved class D design is 50% smaller in size than the GM-Series Class-AB amplifiers whilst offering a significant enhancement in power output capability. It also features much improved circuit design with a self moderating temperature gauge, thus moderating input in accordance with how hot it is. This in turns means there is more flexibility to add multiple subwoofers should you wish.
There are other technical efficiencies (variable low pass and high pass filter) that provide the option to adjust according to personal listening preferences and subwoofer setting characteristics. You can set the LPF and HPF anywhere from 40 Hz to 500Hz.
Another nice feature of the Pioneer GM-D8604 is that even if you don’t have a Pioneer head unit they don’t punish you for it as with some brands. They have made the speaker level inputs compatible with any OEM unit without having to buy adapters, or any unit without the typical RCA-inputs. That means you can have a Pioneer amp in your car without having to replace all the other equipment, keeping costs down and installation time to a minimum.
“5 stars. Awesome highs and mids, powerful and compact, at a nice price point. Definitely worth the money! Quality on the amp components and I’d recommend it, it sounds amazing! Here’s my audio setup Pioneer AVIC-5200NEX Headunit Pioneer GM-D8604 4 Channel Amplifier 2X JBL GT7-6 6-3/4″ rear speakers 2x JBL GTO529 5-1/4 front speakers.”
PROS:
Big power, small size
Stable, durable circuitry
Can connect to multiple subwoofers
Extreme efficiency and high quality sound
CONS:
One reviewer recommended purchasing alongside a sub for exceptional sound quality
JL Audio JX1000/1D 1000 Watt Class D Car Amplifier
This is one of the most potent car amplifiers, and it has also been voted as one of the best car amplifiers in 2017. It is amazingly compact and can provide different power outputs such as the 5000 rms which is produced at 40 hms and 750 rms at 30 hms.
It is well equipped to drive even the toughest subwoofer loads with crisp sound quality and excellent control. Designed specifically for application with subwoofers.
Other great features found in this amplifier include the soft start turn-on which is great for preventing that annoying clicking and popping when the system turns on, ensuring the sound is even and smooth.

Rockford Fosgate prime 750 Watt Class D Amplifier
Apart from the great price that this gadget is sold at, it can delivery full, rich bass to any system aswell through it’s class D circuitury. It is also optimised for subwoofers with the addition of an infrasonic filter to protect your subwoofer from those inaudible bass notes. For an all singing all dancing Rockford Fosgate sound system, simply pair with a 4- channel stereo amplifier to make any Car Audio Fanatic weak at the knees.
Manufactured by Fosgate, this mono amplifier makes us remember why Fosgate has such a reputation for quality.
If you’re concerned over safety then you need not be with this lovely bit of kit; this is because it is crafted with tri-stage protection that covers the thermal, over current and short circuits hence ensuring there is a continuous flow of current. It is also ideal for the people who are looking for a simple amplifier for their car considering that it only has one channel.
Other great features found on this device include the onboard PEQ which is equipped with 18 dB which provides a boost of up to 45Hv. Rockford also provides a watt output of up to 750 watts. Although this gadget is small, it is one of the best car bass amplifiers on the market.
“I cannot believe how well this little amplifier works. I replaced a generic 2000w with this little 750w. Fosgate is known well for their quality and this amplifier does not dissapoint. I was able to change my 2ohm dvc from 4 ohm to 1ohm. Heat after an hour of driving with this unit is hardly noticeable. Summer heat is hotter than this runs while in use. Output is amazing. So thrilled to change from a huge (nearly 3x the size) amplifier to this small unit and get even better quality bass output. I run a Fosgate T112D2, amp at less than 3 gain, no boost, and on 50 of 62 volume, pull 130db – Not tuned. Yes, I am thrilled.”
PROS:
It is compelling and provides the best and clear bass.
All reviewers cited it didn’t get hot or cut out under any conditions
Out performs most amps three times it’s size
CONS:
One reviewer found the packaging to be damaged on the outside but the inner packaging protected the amp
Had too much power for one p2d2-12 burnt it up in 2 weeks

Easy install. Product Dimensions in Inches (L x W x H): 12 x 9 x 4.5
“Powering a pair of Polk db502s in the soundbar of my 05 Wrangler. I have to keep the gain at low or else my ears will bleed. Its not a straining type of loud but a clean, effortless sound. The tweeters in the speakers really come to life. It does get a little warm but nothing too concerning as long as you have plenty of air space for it to cool. I ran this on a two hour road trip with volume over 50% and it was fine. I also tried wiring an 8in 2ohm DVC sub and it powered that very nicely. The sub is a Skar Audio IX-8 D2 150W RMS – 300W Max. It was the perfect match for this sub wiring in parallel. The instructions said its cant do 1 ohm parallel but I ran with no issues. I have always owned Pioneer decks and speakers but this is the first Pioneer amp I’ve ever owned. The quality of sound is second to none.”
PROS:
The price of the gadget is excellent, and it also has high-quality sounding.
CONS:

BBC: Gravity probe exceeds performance goals
Media captionStefano Vitale: “LISA Pathfinder has been an amazing success”
The long-planned LISA space mission to detect gravitational waves looks as though it will be green lit shortly.
Scientists working on a demonstration of its key measurement technologies say they have just beaten the sensitivity performance that will be required.  
The European Space Agency (Esa), which will operate the billion-euro mission, is now expected to “select” the project, perhaps as early as June.
The LISA venture intends to emulate the success of ground-based detectors.
These have already witnessed the warping of space-time that occurs when black holes 10-20 times the mass of the Sun collide about a billion light-years from Earth.
LISA, however, aims to detect the coming together of truly gargantuan black holes, millions of times the mass of the Sun, all the way out to the edge of the observable Universe.
Researchers will use this information to trace the evolution of the cosmos, from its earliest structures to the complex web of galaxies we see around us today.
The performance success of the measurement demonstration was announced here in Boston at the annual meeting of the American Association for the Advancement of Science (AAAS).
It occurred on Esa’s LISA “Pathfinder” (LPF) spacecraft that has been flying for just over a year.
This probe is trialling parts of the laser interferometer that will eventually be used to detect passing gravitational waves.
When Pathfinder’s instrumentation was set running it was hoped it would get within a factor of 10 of the sensitivity that would ultimately be needed by the LISA mission, proper.
In the event, LPF not only matched this mark, but went on to exceed it after 12 months of experimentation.
“You can do the full science of LISA just based on what LPF has got. And that’s thrilling; it really is beyond our dreams,” Prof Stefano Vitale, Pathfinder’s principal investigator, told BBC News.
Gravitational waves – Ripples in the fabric of space-time
Image copyright LIGO
Gravitational waves are a prediction of the Theory of General Relativity
It took decades to develop the technology to directly detect them
They are ripples in the fabric of space and time produced by violent events
Accelerating masses will produce waves that propagate at the speed of light
Detectable sources ought to include merging black holes and neutron stars
LIGO fires lasers into long, L-shaped tunnels; the waves disturb the light
Detecting the waves opens up the Universe to completely new investigations
The first detection of gravitational waves at the US LIGO laboratories in late 2015 has been described as one of the most important physics breakthroughs in decades.
Being able to sense the subtle warping of space-time that occurs as a result of cataclysmic events offers a completely new way to study the Universe, one that does not depend on traditional telescope technology.
Rather than trying to see the light from far-off events, scientists would instead “listen” to the vibrations these events produce in the very fabric of the cosmos.
LIGO achieved its success by discerning the tiny perturbations in laser light that was bounced between super-still mirrors suspended in kilometres’ long, vacuum tunnels.
LISA would do something very similar, except its lasers would bounce between free-floating gold-platinum blocks carried on three identical spacecraft separated by 2.5 million km.
Laser science: Lisa Pathfinder’s technology demonstration
Image copyright ESA
Image caption A cutaway impression of the laser interferometer system inside Lisa Pathfinder
Lisa Pathfinder’s payload is a laser interferometer, which measures the behaviour of two free-falling blocks made from a platinum-gold alloy
Placed 38cm apart, these “test masses” are inside cages that are very precisely engineered to insulate them against all disturbing forces
When this super-quiet environment is maintained, the falling blocks will follow a “straight line” that is defined only by gravity
It is under these conditions that a passing gravitational wave would be noticed by ever so slightly changing the separation of the blocks
Lisa Pathfinder has demonstrated sub-femtometre sensitivity, but the satellite cannot itself make a detection of the ripples
To do this, a space-borne observatory would need to reproduce the same performance with blocks positioned 2.5 million km apart
In both cases, the demand is to characterise fantastically small accelerations in the measurement apparatus as it squeezed and stretched by the passing gravitational waves.
For LISA the projected standard is to characterise movements down below the femto-g level – a millionth of a billionth of the acceleration a falling apple experiences at Earth’s surface; and to do that over periods of minutes to hours.
LISA Pathfinder has just succeeded in achieving sub-femto sensitivity over timescales of half a day. Getting stability at the lowest frequencies is very important.
“The lower the frequency to which you go, the bigger are the bodies that generate gravitational waves; the more intense are the gravitational waves; and the more far away are the bodies. So, the lower the frequencies, the deeper into the Universe you go,” explained Prof Vitale, who is affiliated to Italian the Institute for Nuclear Physics and University of Trento.
To be clear, LPF cannot itself detect gravitational waves because the “arm length” of the system has been shrunk down from 2.5 million km to just 38 cm – to be able to fit inside a single demonstration spacecraft – but it augurs well for the full system.

Image caption Artwork: The LISA concept envisages three spacecraft linked by laser arms that are 2.5 million km in length
Esa recently issued a call for proposals to fly a gravitational science mission in 2034. The BBC understands the agency received only one submission – from the LISA Consortium.
This is unusual. Normally such calls attract a number of submissions from several groups all with different ideas for a mission. But in this instance, it is maybe not so surprising given that the LISA concept has been investigated for more than two decades.
Prof Karsten Danzmann, co-PI on LPF and the lead proposer of LISA, hopes a way can be found to fly his consortium’s three-spacecraft detection system earlier than 2034, perhaps as early as 2029. But that requires sufficient money being available.
“The launch date is only programatically dominated, not technically,” Prof Danzmann told BBC News.
“And with all the interest in gravitational waves building up right now, ways will be found to fly almost simultaneously with Athena (Europe’s next-generation X-ray telescope slated to launch in 2028).
“This would make perfect sense because we can tell the X-ray guys where to look, because we get the alert of any bright (black hole) merger immediately, and then we can tell them, ‘look in the next hour and you’ll see an X-ray flash’.”
“That would be tremendously exciting to do multi-messenger astronomy with LISA and Athena at the same time.”
LISA could be selected as a confirmed project at Esa’s Science Programme Committee in June. There would then be a technical review followed by parallel industrial studies to assess the best, most cost-effective way to construct the mission.
Agreement will also be sought with the Americans to bring them onboard. They are likely to contribute about $300-400m of the overall cost in the form of components, such as the lasers that will be fired between LISA’s trio of spacecraft.
The LPF demonstration experiments are due to end in May, or June at the latest.

It is under these conditions that a passing gravitational wave would be noticed by ever so slightly changing the separation of the blocks
Lisa Pathfinder has demonstrated sub-femtometre sensitivity, but the satellite cannot itself make a detection of the ripples
To do this, a space-borne observatory would need to reproduce the same performance with blocks positioned 2.5 million km apart
In both cases, the demand is to characterise fantastically small accelerations in the measurement apparatus as it squeezed and stretched by the passing gravitational waves.
For LISA the projected standard is to characterise movements down below the femto-g level – a millionth of a billionth of the acceleration a falling apple experiences at Earth’s surface; and to do that over periods of minutes to hours.
LISA Pathfinder has just succeeded in achieving sub-femto sensitivity over timescales of half a day. Getting stability at the lowest frequencies is very important.
“The lower the frequency to which you go, the bigger are the bodies that generate gravitational waves; the more intense are the gravitational waves; and the more far away are the bodies. So, the lower the frequencies, the deeper into the Universe you go,” explained Prof Vitale, who is affiliated to Italian the Institute for Nuclear Physics and University of Trento.
To be clear, LPF cannot itself detect gravitational waves because the “arm length” of the system has been shrunk down from 2.5 million km to just 38 cm – to be able to fit inside a single demonstration spacecraft – but it augurs well for the full system.

Esa recently issued a call for proposals to fly a gravitational science mission in 2034. The BBC understands the agency received only one submission – from the LISA Consortium.
This is unusual. Normally such calls attract a number of submissions from several groups all with different ideas for a mission. But in this instance, it is maybe not so surprising given that the LISA concept has been investigated for more than two decades.
Prof Karsten Danzmann, co-PI on LPF and the lead proposer of LISA, hopes a way can be found to fly his consortium’s three-spacecraft detection system earlier than 2034, perhaps as early as 2029. But that requires sufficient money being available.
“The launch date is only programatically dominated, not technically,” Prof Danzmann told BBC News.
“And with all the interest in gravitational waves building up right now, ways will be found to fly almost simultaneously with Athena (Europe’s next-generation X-ray telescope slated to launch in 2028).
“This would make perfect sense because we can tell the X-ray guys where to look, because we get the alert of any bright (black hole) merger immediately, and then we can tell them, ‘look in the next hour and you’ll see an X-ray flash’.”
“That would be tremendously exciting to do multi-messenger astronomy with LISA and Athena at the same time.”
LISA could be selected as a confirmed project at Esa’s Science Programme Committee in June. There would then be a technical review followed by parallel industrial studies to assess the best, most cost-effective way to construct the mission.
Agreement will also be sought with the Americans to bring them onboard. They are likely to contribute about $300-400m of the overall cost in the form of components, such as the lasers that will be fired between LISA’s trio of spacecraft.
The LPF demonstration experiments are due to end in May, or June at the latest.

BBC: Gravity probe exceeds performance goals
Media captionStefano Vitale: “LISA Pathfinder has been an amazing success”
The long-planned LISA space mission to detect gravitational waves looks as though it will be green lit shortly.
Scientists working on a demonstration of its key measurement technologies say they have just beaten the sensitivity performance that will be required.  
The European Space Agency (Esa), which will operate the billion-euro mission, is now expected to “select” the project, perhaps as early as June.
The LISA venture intends to emulate the success of ground-based detectors.
These have already witnessed the warping of space-time that occurs when black holes 10-20 times the mass of the Sun collide about a billion light-years from Earth.
LISA, however, aims to detect the coming together of truly gargantuan black holes, millions of times the mass of the Sun, all the way out to the edge of the observable Universe.
Researchers will use this information to trace the evolution of the cosmos, from its earliest structures to the complex web of galaxies we see around us today.
The performance success of the measurement demonstration was announced here in Boston at the annual meeting of the American Association for the Advancement of Science (AAAS).
It occurred on Esa’s LISA “Pathfinder” (LPF) spacecraft that has been flying for just over a year.
This probe is trialling parts of the laser interferometer that will eventually be used to detect passing gravitational waves.
When Pathfinder’s instrumentation was set running it was hoped it would get within a factor of 10 of the sensitivity that would ultimately be needed by the LISA mission, proper.
In the event, LPF not only matched this mark, but went on to exceed it after 12 months of experimentation.
“You can do the full science of LISA just based on what LPF has got. And that’s thrilling; it really is beyond our dreams,” Prof Stefano Vitale, Pathfinder’s principal investigator, told BBC News.
Gravitational waves – Ripples in the fabric of space-time
Image copyright LIGO
Gravitational waves are a prediction of the Theory of General Relativity
It took decades to develop the technology to directly detect them
They are ripples in the fabric of space and time produced by violent events
Accelerating masses will produce waves that propagate at the speed of light
Detectable sources ought to include merging black holes and neutron stars
LIGO fires lasers into long, L-shaped tunnels; the waves disturb the light
Detecting the waves opens up the Universe to completely new investigations
The first detection of gravitational waves at the US LIGO laboratories in late 2015 has been described as one of the most important physics breakthroughs in decades.
Being able to sense the subtle warping of space-time that occurs as a result of cataclysmic events offers a completely new way to study the Universe, one that does not depend on traditional telescope technology.
Rather than trying to see the light from far-off events, scientists would instead “listen” to the vibrations these events produce in the very fabric of the cosmos.
LIGO achieved its success by discerning the tiny perturbations in laser light that was bounced between super-still mirrors suspended in kilometres’ long, vacuum tunnels.
LISA would do something very similar, except its lasers would bounce between free-floating gold-platinum blocks carried on three identical spacecraft separated by 2.5 million km.
