aliciaa, ma ta thik tha... :) aliciaa, you are missing out your own point. the General Theory of Relativity, doesnt not figure the absoulute scale of things. so, therefore size is rahter just a relative matter to this theory, because no matter how small or how large the universe is it will behave the same..so yes, there is an expanding universe but there is no certain size of universe.. ok now am out to wrk :)
