I'll kick us off.

Morgan Fisher from Waterloo, Ontario.

It's a slightly longer one, so bear with me.

It is my understanding that quarks always exist in pairs, and separating the pairs creates enough energy to generate a new quark.

Here's my question.

that means that everything right down to quarks will be torn apart, but tearing apart quarks generates new quarks.

Could this mean another Big Bang?

If so, does this provide evidence that our current universe is simply one in an infinite number of universes that emerge, exist, then undergo another big rip from the infinite past to the infinite future?

It shows you how far away from knowing certainty is.

We are.

Only 95%.
