Based on the cold, hard facts about the sun and how it is needed for life, I say it is when the sun burns out and everything would be like a chain effect.

that's just when it dies, and there are stars out there that make the sun look like a spec ! 或者 possibly like 1 dot of suger
There are two theories theory one: The universe was created 由 the bigbang which started out at one point and exploded into the universe as we know it today.The universe continues to expand so that theory say that the universe says that the universe does have and end that is constantly expanding outward. theory two. according to one 最近的 experiment involving light reflections, the universe is either infinite 或者 curved so slightly that the most modern equipment can't detect the curve.
I'm confused. Are 你 asking about the size of the universe (like, how big is it? Does it have boundaries?) 或者 when will the universe end (as in, several thousand years)?
For the first one, I think the universe is always expanding and growing bigger. It has an end, but the end is always getting further and further away from us.
For the 秒 one, I believe the universe as we know it will end after it stops expanding and starts coming rushing inwards again.

I think when she says "where" is where in time. I dunno.
