What will happen to the universe 1 googolplex years from now?

Answer 1

There is no scientific proof of what will or can happen to the universe tomorrow so nobody can really say what will happen in 1 googolplex years from now. I would hope that there is space travel and flying cars by then though.

Answer 2

What we do today will affect thousands but won't affect years that are duotrigintillions of digits long. Honestly using physics, there are multiple other predictions, like if there is no proton decay, the Degenerate Era will last 10^1500 (novemnonagintaquadringentillion) years. Stellar remnants will fuse into dense ball of iron, known as Iron-56. Later in the long elapsed Black Hole Era, we will see Boltzmann brains from 1 hexecillion (3*quindecillion+3 zeroes) to 1 heptecillion (3*sexdecillion+3 zeroes) years. Entropy will finally decrease, as we will see islands of time and intelligence gain control of the near-infinite universe with worlds emerging. Ludwig Boltzmann's theory is kind of ridiculous in my opinion though. After a penteicosillion (3*quattuorvigintillion+3 zeroes) years, quantum tunneling will push all stellar remnants into black holes, and these will naturally break down in hopefully, a googolplex years.

Many physicists do suggest proton decay, and that the Hawking radiation will take place between 10 unvigintillion and 1 octotrigintillion years. After that, the universe becomes static and bleak with a frozen ocean of subatomic particles. I do think there is always a chance for life to survive again.
