There was a hypothesis that we live inside a black hole and that dark energy is another black hole merging with us, increasing the size.<p>Here's a video from The Royal Institute on this subject: <a href="https://www.youtube.com/watch?v=A8bBhkhZtd8" rel="nofollow">https://www.youtube.com/watch?v=A8bBhkhZtd8</a>
It's possible that spacetime expansion oscilates:<p><a href="https://www.researchgate.net/publication/330726290_Confirmation_of_Inflaton-like_Oscillations_in_the_Scale_Factor_from_the_Pantheon_Compilation_of_1048_SNe1a" rel="nofollow">https://www.researchgate.net/publication/330726290_Confirmat...</a><p>Main frequency is around 7 times per age of the Universe. Secondary one is around 10.5 times.<p>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.
Not sure I want to read as much for a single takeaway so can somebody help me here?<p>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?
