• Question: To scientists, is it true space is stretching and getting bigger too quickly? Could there be a second big bang tht produces life? if there is what are the odds of it happening? :L

      yes, the universe is getting bigger, and is accelerating. Current cosmological observations suggest that the universe will continue expanding forever, so probably there won’t be another implosion and a big crunch

      Yes! The Nobel prize for physics last year was awarded to the people who have shown that the expansion of the universe is speeding up (they do this by looking at lots of distant exploding stars called supernova).
      We don’t really know whether the expansion of the universe is going to keep speeding up, or if the expansion will eventually slow down and the universe will colapse back on itself. If this happened then there could be a second big bang afterwards.
      It’s hard to give the odds of this happening because we don’t have any evidence to base those odds on. But one thing we can be sure of, if there is a second big bang we wont be around to see it!

      the universe is getting bigger, but I think it’s doing it at the right pace. If the universe starts collapsing again then we could have a big bounce, where everything goes back to one place again and then we have another big bang.
