I don't plan on dying until 1x10^10^1500 years in the future. And yes. That exponent has an exponent on it. If our current understanding of entropy maintains itself then that is the absolute limit for anything. After that period of time EVERYTHING will be gone. No matter, no useable energy, no nothing. Even the unusable energy will be gone as it will be stretched by space into a point of essential non-existence.
On the bright side, space is expanding while maintaining a constant amount of energy. That energy is coming from somewhere and we have absolutely no idea where. But it wouldn't matter. After that long a period of time everything will have been stretched. Everything would be pulled apart. First star systems, next are galaxies, then the stars, then planets, then chemicals forming essentially everything (Any kind of life is just a bit before this), then atoms (Nothing exists anymore), and finally quantum mechanical bits and pieces. The universe will have pulled itself so much that it would be essentially empty and at absolute zero. Think of stretching a sheet out. It would tear, but ignore that and think of the pieces still being stretched. Eventually this stretching would pull apart every piece of fabric in that sheet. That is what's happening to our universe right now. That's why we have red shifting (The changing of color of distant stars).
Well, in only a few trillions years there will be no more galaxies for us to see. All of them will have been 'stretched' away faster than the light they give off can get to us. We call that going over the cosmological horizon. Once something goes over this line, it can never come back under modern physics. You would have to go faster than the speed of light - and potentially many times faster than that given enough time. Nothing would look like nothing. There would be nothing. No atoms, no energy, no light, no heat, and no motion. Call it oblivion if it helps, but it is just nothing. Absolute nothing.
I find this fascinating, trying to comprehend the incomprehensible. What does absolute nothing look like? What truly is the A axis, not counting the theory on it being time? Can we truly discover a brand new color in our lifetime? If there was a universe where everything that didn't exist existed, what would everything look like?
This is like my drug
We can't discover new colors. It would be exactly like trying to make a new number. We kinda have all of them that can exist already. But we can learn how to MAKE new colors. Just because we know about colors doesn't mean we can make any color we want. We still have to make the chemicals that can dye such things certain colors. I'm going to bed, but here's a little video to entertain you about making colors: https://www.youtube.com/watch?v=CYB-pmNs4VQ

Not true at all. Everyone is seriously freaking out way too much about this. Nature is definitely getting hurt, but we are NOT going to die from it. In case you haven't noticed we are kinda doing better than ever even with the Earth slowly becoming a piece of shit. We should preserve nature, but it's not that big an issue when compared to other shite. Worry about climate change instead; that's the far more pressing issue that is actually a threat.
Science!!!
