HOW OLD IS OUR SOLAR SYSTEM??

Blog#354

Saturday, December 2nd, 2023

Welcome back,

How old is the Solar System? That is a question that cuts to the heart of it all. By studying several things, mostly meteorites, and using radioactive dating techniques, specifically looking at daughter isotopes, scientists have determined that the Solar System is 4.6 billion years old. Well, give or take a few million years. That age can be extended to most of the objects and material in the Solar System.

The United States Geological Survey(USGS) website has a lot of indepth material about how the age of the Solar System was determined. The basics of it are that all material radioactively decays into a stable isotope. Some elements decay within nanoseconds while others have projected half-lives of over 100 billion years. The USGS based their study on minerals that naturally occur in rocks and have half-lives of 700 million to 100 billion years.

These dating techniques, known as radiometric dating, are firmly grounded in physics and are used to measure the last time that the rock being dated was either melted or disturbed sufficiently to re-homogenize its radioactive elements. This techniques returned an approximate age for meteorites of 4.6 billion years and Earth bound rocks around 4.3 billion years. The USGS admits that they were unable to find any rock that had not been altered by the Earths tectonic plates, so the age of the Earth could be refined in the future.

When the gasses of the early solar nebula began to cool, the first materials to condense into solid particles were rich in calcium and aluminum. Eventually solid particles of different elements clumped together to form the common building blocks of comets, asteroids, and planets. Astronomers have long thought that some of the Solar System’s oldest asteroids should be more enriched in calcium and aluminum, but, none had been identified until recently. The the Allende meteorite of 1969 was the first to show inclusions that were extremely rich in calcium and aluminum.

It took 40 years for the spectra of the inclusions to be discovered and then extrapolates to very old asteroids still in orbit around the Sun. Astronomer Jessica Sunshine and colleagues made this discovery with the support of NASA and the National Science Foundation. Additionally, the Universe is thought to have been created about 13.7 billion years ago.

Measuring two long-lived radioactive elements in meteorites, uranium-238 and thorium-232, has placed the age of the Milky Way at in the same time frame. From these measurements, it appears that large scale structures like galaxies formed relatively quickly after the Big Bang.

Product Review: Window Solar Charger

Company/Website: Grouphug Solar

Does it work: Yes.  I tested it by using it to charge my cellphone.

Price: $149, I bought mine on sale for $129.

Operation: You’re looking at it. The button turns on yellow, red, or green LED lights that tell you whether the panel is getting enough light to operate, and how charged it’s (included) battery is, but it will charge your devices whether you ever push this button or not.

Assembly/Installation: Comes out of the box fully assembled as shown.  Stick the included suction cup to a window and hang it up.

Overall: I like it.  You get what you pay for.  It does one thing, but it does it well, and I’ve seen desk lamps that were more complicated to use.

I am not affiliated with Grouphug Solar, nor am I making any money off this.

Opinion on solar panels?

I like them. It lets people turn my Hatebeams into electricity.

The simple genius of solar canals explained. The southwestern U.S. is in the throes of a “megadrought” so severe that we’ve broken the record — all 1,200 years of it. Researchers from the University of California have proposed a solution that could potentially address both the water and energy crises at the same time: covering irrigation canals with solar panels. But is this just another renewable energy gimmick, or does it hold a little more water? Let’s take a deeper dive to find out.

In 2015, two geographers noticed solar panels popping up on houses in their small US state of Connecticut. Curious, they set out to see if they could figure out what predicted who had them. Would they be in richer homes? Or in areas with higher population density?

Early adopters of solar panels tend to be people who are interested in innovative technology, who find an installer they trust, and who think having solar panels will benefit them. But once an early adopter made their choice, the geographers found, a cluster would spring up around them. Having solar panels on a house near you, where you could see them and talk to a real live person who had them, it turned out, was the biggest predictor of whether you’d get them yourself. 

Why? Because it brought down the “cost” of information. You didn’t have to go somewhere or find a new person to talk to; they were right there beside you and ready and eager to bend your ear with all the information you needed to make the same choice they had.

Electricity and food (prose poetry)

solar panel(from Amazon)

Electricity is created as a substitute for something. The energy for a "hydrogen car" or "electric car" is made at a power plant. It could be energy produced by a nuclear power plant. (Energy cannot be created from zero.)

In addition, solar power generation, which is much better than nuclear power generation and is a powerful alternative energy to nuclear power generation, often has panels lined up on flat areas that would otherwise be farmland, but this makes it impossible to produce food.

In the case of wind power, it "takes the air out of the plants". It is said that since ancient times, crops have grown in a natural environment called "five winds and ten rains," in which strong winds hit every five days and rain fell every ten days.

People may end up sacrificing food production in order to live a more convenient life. Come to think of it, the "ethanol car" was a very barter of energy and food.

Note: I am anti-nuclear. I just wanted to mention the limits of renewable energy.

電気と食糧（散文詩）

電気は「なにものかの代替品」として作られる。「水素自動車」とか「電気自動車」のエネルギーは発電所で作られる。原子力発電所でつくられるエネルギーかも知れない。（ゼロからエネルギーは作れない。）

また原発より遥かにマシで原発の代替エネルギーとして有力な太陽光発電は本来農地となる平坦な場所にパネルを並べることが多いが、その分食糧の生産は出来なくなる。

風力発電の場合、「植物の空気を奪う」。古来「五風十雨」、といって５日おきに強い風を受け、１０日ごとに雨が降るという自然環境で作物は育っていたと、いうことだ。

人は便利な暮らしをするために、食糧生産を犠牲にすることになるかも知れない。そういえば「エタノール車」は、エネルギーと食糧の物物交換だった。

注：私は原発反対派です。ただ、再生可能エネルギーの限界に言及したかったのです。
