"The amount of time the universe itself has left—around 0.65 billion billion years." Is this true?? I've never heard this claimed before.

- Mtinie 7y agoI’ve never seen it framed that way, but they may be referencing the estimated timeframe for the “heat death” of the universe: https://en.m.wikipedia.org/wiki/Heat_death_of_the_universe https://en.m.wikipedia.org/wiki/Heat_death_of_the_universe
- anm89 7y agoYeah that was my assumption but I've never seen that specific time frame proposed and it just seems like the kind of thing I would have heard of if it was a know fact.
- mensetmanusman 7y agoYou can estimate this because there is a known amount of energy around in the visible universe (energy, mass, etc.). We know from inflation that this number changes at a given rate. We also know that time and entropy are connected, so when entropy of the known universe is at the maximum, it would be essentially meaningless to say time could continue, i.e ‘the end of time.’
