Question:
We know that a big crunch will occur after many years. The universe is now expanding. Up to what limit will it expand? What is the final limit of our universe?


Replies:
Kumardip,

I do not think there is enough evidence to say that the Big Crunch will occur. We have not found sufficient mass to cause a reversal to the expansion, we are currently observing an accelerating rate of expansion, and our strongest telescopes has not allowed us to see beyond a certain distance/time - we do not know.

Very good question. We do not know. Nor do we know if the expansion will ever stop; right now there is evidence that it will never stop, and that the expansion is even accelerating.

Sincerely David H. Levy
