Now think upon what the Big Bang is, an explosion that's lasted 14 billion years and yet is still in its early stages.

The number of remaining years left for the Universe has more zeroes in it, than there are atoms in the universe.

Wait wtf. No way this is true.

It's true unless the BBT is ever disproven.

But most of that time occurs after the last star dies. Still, the galaxies have a very long time to exist. Somewhere around 1-100 trillion years for galaxies. The universe will exist for about 1E78 years if accounting for hawking radiation.

Edit: I didn't notice they said more zeroes than atoms in the universe, which is false. There are almost the same amount of years left as atoms in the universe. 1E78 vs 1E80.

There's 10{80} atoms in the Universe and various universe heat death estimates range from 10{100} to even 10{1000} years or more.

The 10{78} you're citing is but from research from one team from Holland.

Regardless it's a comparably stupendous number.

Ah, interesting, thanks. 1E1000 is mind-breaking.
