Problems with an Infinite Universe

One reason I don't really like these discussions is that they get over the heads of almost all of us pretty quickly (eta being a probably exception).My guess (and I want to emphasize GUESS) is that space proves to be the tensors in Einstein's GR equations. ( I did try to read an advanced text on GR once but got lost less than a quarter of the way through). I think your definition of it being "everything" is too broad and not useful.Space-time is the backdrop upon which energy-matter does it's thing. I can't even hope to do much better than that.It may prove to be the 4D part of the full 11 dimensions that the "real" universe operates in but it's so wild, so speculative and so laden with difficult math that I think we have to leave it untill we have someone who can explain it available.Once again, at the edges, "I don't know" is a necessary answer sometimes. What I, personally, don't know is if anyone knows the answers in this area. Or if they do would we understand the answer anyway .This message has been edited by NosyNed, 06-23-2004 10:11 PM

I'm pretty sure it doesn't have to displace anything.I'm not sure if it has to expand into anything. If it does that anything certainly isn't "in" our universe and it's 4 dimensions.

This is hardly at the state of "shown". It is a very promising lead into advances in our understanding. But we aren't there yet.

I think Einstein would have agreed with you. However, he turned out to be wrong on a number of issues in QM.This message has been edited by NosyNed, 06-24-2004 11:24 AM

It is apparent from the very next post that he might as well be ignored. Nipok is armoured very thickly indeed in ignorance. It doesn't appear that anything sort of a relativistic asteroid is going to get through.Sorry about the food poisoning. I was flat on my back all day monday with fever and aches and upsets but I don't think it was food poisoning.

Various religions will continue just as they have. There will be ongoing splits forming as different sects find something to fight over. New guru's will pop up and gain a following. Other sects will die away. There will not be a lot of change in the next few decades.There will certianly not be a general agreement in this century.
