Vacuum Energy

Introduction In quantum field theory, vacuum energy is the zero-point energy of all the fields in space. This includes both the electromagnetic field and the other fundamental fields. It’s the lowest possible energy that a quantum mechanical physical system may have and is the energy of empty space. Zero-Point Energy The notion of vacuum energy is closely related to the concept of zero-point…

The Biggest Problem of Them All

From Physics World, something unexpected. The “problem” is, er, the Universe. Problems don’t come much bigger! To put this in perspective, the major theory used to describe it is Einstein’s General Relativity. There is only one problem with that theory: everything should collapse into a singular “point” and it doesn’t. To get around that problem, Einstein introduced something he called “the…

“I don’t have any favorites from the trailer” I say as I blatantly post my favorites from the trailer

I feel like people (especially my brother) who have dishwashers and never hand wash anything don't appreciate how much more general cleaning you can get done when you don't have to hand wash every single dish you use. Especially when dealing with chronic fatigue, executive dysfunction and a full time job.

My surfaces might be uncluttered too if I didn't have the daily grind of the fucking dishes. When I hear somebody say they vacuum every day I just glare at them and think "dishwasher".

#but feel free to shame me for not having more energy to vacuum every day in the notes #don't think I've forgotten the fucking top sheet discourse

on this beautiful Saturday morning I have the unique and wonderful opportunity to shampoo the carpets in my apartment

#when we moved in they were gross but like I did not have the time/energy/money etc to deal with them aside from vacuuming #but now there are BEASTS. IN THE APARTMENT #AAAAAUUUUUUUGGGHHH!!!! #I literally start classes next week 😭 come on man 😭 can’t catch any fucking breaks

crying hysterically i have such a good fic idea for post-cataclysm teyvat but i just dont have enough time for another series rn

#so after doing the elynas quest #spoilers for that by the way #and the mary ann quests #but anyway #post cataclysm teyvat was rlly like an #apocalyptic place #kind of like fallout where abyss energy was like everywhere and very radioactive #and the institute had devoted itself to clean the abyssal energy but after it disbanded when the director died during the cataclysm #a secret group called the ordo formed and experimented with the energy in elynas's corpse -- who is assumed to be another dragon-creature o #rhinedottir and we already know that one of the secret members had interacted with the energy and became something akin to an #abyss inquisitor but he was unaffiliated with the fatui and the abyss order #but now i lowkey want to write a long fic series where reader was part of that secret group post-cataclysm #and also became corrupted by the energy and it would flip between the past and present #-- since we dont know neuvillette's part in the cataclysm i assume he was defending fontaine but that's only an assumption #and then maybe after the cataclysm he was filling in the power vacuum after the lord of amrita's death (first hydro archon) #but regardless in the past reader was going to be close with neuvillette maybe she was an ambassador for the narzinssenkreuz institute #before it disbanded which is how she met him and got the chance to get close to him. then the catacysm happens where they're forced to #separate because of all that's going on #and after it #she gets involved with the ordo. it would flip between the past and present #where in the present she's started to affiliate with the fatui -- reasons unknown as of yet but im not writing a fic without dottore as a #love interest but it would showcase the past and present - kind of like how little dark age did with half of the chapter set in the past an #the other part in the present -- so it would showcase 1) her relationship with neuvillette both while she's part of the institute and then #the decline of it as she becomes part of the ordo. it would also showcase pre during and post cataclysm fontaine. and then the present woul #probably focus on directly before pre-canon (like heliotropes) and into maybe both the sumeru archon quests and the fontaine archon quests #where she would end up meeting neuvillette again. this fic i would try to keep this one close to canon fontaine unlike heliotropes

having adhd is so funny because you will be in the middle of cleaning and suddenly have the great idea to take apart your entire mechanical keyboard to deep clean it but then you get halfway through doing it and realize what a mistake it was lmao

#i did finish and put it back together but now i don't have the energy to finish vacuuming rip #personal.txt

I keep seeing your tags and how you've mentioned you've been tired because of work, so -- sending you so much love and happiness and good energy ❤️ You deserve everything good!

EUEEEEE THANK YOU SO MUCH ;;_;;<333333 I am, I am so, so tired, but I requested three weeks of holiday and it was approved so in a couple of weeks I can REST 🙏 (and I'm probably going to quit this awful job soon after tbh I'm at my limit haha)

YOU DESERVE EVERYTHING GOOD, TOO. Never forget your worth and how much better you make this world just by existing!!!!! I love you sm!!!!!!!!

#asks #i'm vacuuming all the love and happiness and good energy so i'll survive until the vacation nom nom

just deep clean vacuumed my car and I've never felt more alive

#for context #i dont think ive vacuumed that thing the entire year and a halfish ive had it #and i spent a year of that working at a doggy daycare #it was pretty nasty #just never had the energy to do it or never remembered to or anything #ramblings

#god one day i’ll have the energy to clean my room #i just feel like if i can’t clean everythibg then what’s the point #like i can’t just pick up and clean my sheets if i’m not also vacuuming and washing the floors and walls and dusting and cleaning my window #AAAAA #i need a full day to just clean my room before #i go insane #jas rants

not to toot my own horn but it feels so jarring to reblog the anniversary of the moon landing and also be doing irl research to support current cislunar activities

#science shit #redglyphs #sometimes i feel like a bad internet-er for not being as hype about stuff i should like/area of expertise #but then i tell myself i come online to be stupid for a bit #and i get analysis paralysis when it comes to communicating topics i invest a lot of time/energy into #like you see those bloggers that bring their expertise and make those cool interesting informative posts? i can't be like that #it'd kill me to post a thing and then realize ''i forgot about this! but there's this caveat... argh wrong word choice--'' #or i just don't have strong strong feelings about what others think of a thing #or idk. i'm not good at talking about something in a vacuum (hah.) #an obsessed guy on some kerbal forum could probably say more off-the-cuff about space stuff than me #until a hyperspecific question gets asked and i'm just ''eh idk ig'' still

For the zombie au, is there like a cure thing at the end? And also which death counts like the ones that officially died post-crisis before being retconned in rebirth? Or like every death in dc history? And just the characters that died and came back or died and are canonically still dead (or because the writer forgot they existed) but in this au they're back?

(context) hehe thank you so much for asking <3

there is a cure at the end! at first in my head it was an elseworld so i was gonna make there not be a cure but then i switched the story to just being a main universe thing so it does not end with everyone dying 😔 i wont get too into how it happened but basically nika (flatline from robin 2021) sorta accidentally causes it and the way to stop it is to kill her (#rip sorry about ur gf damian)

for the most part, any death that happened post-crisis counts, mostly because of infinite frontier "everything is canon if you want it to be". ie cass died in batgirl 2000 but she stopped existing with the new52 then was recreated in rebirth, but she would still be a zombie bc of her death in post crisis continuity (ps i know spirit world re-canonized her death but i'm using her as an example anyway bc its easy lol)

on the other hand. kara's death does not count. mostly because her death was pre-crisis and the current kara zor-el is not the kara zor-el that died. also clark and kon are both zombies (would that be it for the supers ??? i dont know details of superman characters as much so idk if there would be another big problem) so having one less Unbeatable Force in the mix is a little easier to deal with. basically: deaths count if i personally want them to count but they dont if i dont

characters that havent explicitly come back are still dead </3 if dead people came back it would basically just be blackest night with extra steps so no dead people rising, just living people dying. so like eddie bloomberg, who died in post-crisis (then came back just to die again in heroes in crisis), is still just dead and not a zombie

i hope that answered ur questions, thank you so much for letting me talk about this bc its been consuming my thoughts all day fhdsajfahsdf 😚

#ps recently ive gotten into the habit of doing something productive every time i get a question i want to give a long answer to #bc i used to just sit there and either pace around or talk to my mirror whenever i wanted to think about it #but now instead i put my energy into doing something else. while still talking to myself #this one wasnt THAT long of an answer i guess but i still wanted to think about it #so while thinking about the answer to these i swept and vacuumed my apartment then cleaned the bathroom #thank you for your contribution in making me get shit done that ive been intending to do for weeks 🫡

i wonder how many times jujutsu society was nearly wiped out. it’s briefly mentioned that sorcerers were dropping like flies while curses continued to get stronger in the heian (??) period/in sukuna’s heyday, and i wonder how that compares to now. yuuta’s probably going to die next (before or after kashimo), which means jujutsu society will be losing all four special grades over the course of a year, with three of them dying within a few weeks of each other.

#if sukuna kills yuuta that’s two special grades down in the SAME DAY #also we’re not going to get the answer but WHAT’S UP WITH THE CLANS #WHAT’S GOING ON OVER THERE #inventing my own tedious politics for my mediocre battle shounen bc if i don’t have them i Die #jjk leaks #jjk spoilers #riko.txt #what comes after the massive power vacuum left in their wakes? what ramifications does this have on cursed energy itself???
