What if the new DESI data means dark energy keeps weakening into a negative state, driving a Big Bounce?
Do you still believe in Heat Death? Because the DESI study just blew that entire theory out of the water. They found that dark energy is weakening, it has already lost about 10% of its strength so far (13.8 billion years). Right now there is a 3.5–4.1 sigma level of confidence. That is why researchers and scientists won't label this theory as absolute truth yet, since they need 5 sigma for a definitive discovery, but it is a massive "turn". The funny thing is "Heat Death" is mathematically proven anyway. They just calculated it
based on the old baseline model assuming the cosmos would never change. After realizing that dark energy has slowed down, they added: "What if dark energy weakens by 10% and then just... stays there? It will lead to Heat Death even then."
Assuming that it stays at 10% isn't logical. Why would dark energy suddenly decide to slow down by 10% and stay at that speed forever? "Yeah uh I think I’m gonna chill a little bit"
Does that mean the Big Bounce theory becomes a reality? Well logically, dark energy won’t just slow down by 10% out of nowhere. Once it happens, it will keep slowing down, in fact it (could) become negative.
But now we have another problem. If dark energy becomes negative, it starts pulling rather than pushing, meaning it (nearly) does the same pulling job as dark matter. Space would start pulling inward smoothly on a global scale while dark matter keeps pulling things together locally. We have two pulling forces rather than a needed balance. Which also seems illogical to me, but it makes a cyclic universe more logical.
Through the Big Bounce, the universe gets an infinite number of tries to get the physical constants exactly right for planets & galaxies to form. Even if it had failed an x amount of times, there would be no "you" to be aware of it anyway.
But like I said, if it starts to reverse aka. become negative, dark matter and dark energy nearly have the same "job“. Is it logical? Is it even universally correct?
If fading dark energy is correct (which makes Big Bounce one of the leading theories for me atleast), then we are in the middle age. There are around 10^25 planets in the entire universe. Life, complex life and even intelligent life had enough time to exist before us. We are technically late to the party so…where are they? If intelligent life formed before us, they would have had billions upon billions of years to develop.
They could have created wormholes upon wormholes in order to beat dark energy in the first place. So these are my "conclusions":
1: Either they failed at their job.
2: They weren’t there in the first place. Intelligent life is rarer than we expected.
3: They didn’t fail and we are actually heading toward Heat Death. The 10% "fading" of dark energy was caused by them. They managed to slow down dark energy in the entire universe, which sounds pretty plausible for an intelligent life form that had billions of years with nothing to do.
What do you think? The 10% fading etc. and all other information are from verified sources which I can willingly share. I am sure there might be some slight "miscalculations" in my thoughts, so I would appreciate it if you mention them for others to be aware of. ❤️
