Dark Energy May Be Weakening, Major Astrophysics Study Finds
- pdimitar 3y agoNot sure I want to read as much for a single takeaway so can somebody help me here? Are they saying that the Universe expansion that's been observed to even accelerate with time, is no longer accelerating as much? That the rate of acceleration is slowing down?
- scotty79 3y agoIt's possible that spacetime expansion oscilates: https://www.researchgate.net/publication/330726290_Confirmation_of_Inflaton-like_Oscillations_in_the_Scale_Factor_from_the_Pantheon_Compilation_of_1048_SNe1a https://www.researchgate.net/publication/330726290_Confirmat... Main frequency is around 7 times per age of the Universe. Secondary one is around 10.5 times. When I look at it, I think that dark energy is just ultra strong low frequency gravity wave coming from rotating ultramassive objects far outside of our observable universe and way older than our little local shenanigans we call Big Bang.
- aurareturn 3y agoThere was a hypothesis that we live inside a black hole and that dark energy is another black hole merging with us, increasing the size. Here's a video from The Royal Institute on this subject: https://www.youtube.com/watch?v=A8bBhkhZtd8 https://www.youtube.com/watch?v=A8bBhkhZtd8
- afarviral 3y agoWhat might an observational signature be that supports this hypothesis? Currently, the direct study of black hole interiors is (sadly) impossible.
- revskill 3y agoI agree.
- gjsman-1000 3y agoHow about we just fire all the astrophysicists and make them start over?
- dventimi 3y agoWho's "we"?
- lawgimenez 3y agoThe San-Ti.
- throwup238 3y agoThen the particle physicists win. Do you really want them to win?
- bandyaboot 3y agoWhy would they start over if you’ve fired them?
- mapt 3y agoStart over in a sort of great explosion of astrophysics, sending them at great speed outwards in all directions?
- aurareturn 3y agoWhy? What's with the negativity?
- foxyv 3y agoThat's honestly a pretty cool take on the idea. Imagine if we are just living inside an infinitely nested series of black holes? Turtles all the way down!
