Surely if we believe that nothing lasts forever our universe won't either. I think it must end at some point. I just think that the explosion of the Big Bang was so powerful it still drives the dust and that into the air today. Once it stops then I don't know what will happen. Maybe the Universe will be eternal but parts of it will die. People doing a Degree in Physics will probably know more! Interesting though.
In life you\'ll often find that no answer can be 100% and that sometimes nobody can ever give you an answer that you find acceptable.
