Hey! On leaving the universe 1, I asked what a trip outside our cosmos would be like, assuming a 30 billion lightyear wide universe. Now I read just a moment ago on space.com the following
about new measurements on the size of the universe. They say it's actually close to 158 bln ly in diamenter, because since the beginning some 13 bln years ago, the space in which light travelled has also expanded, as far as I understand, and I don't inderstand very far
"It can be thought of as a spherical diameter is the usual sense" said the scientist in the article.
Now, assuming the science in this article is correct, could we at least come closer to the "edge"? I don't even know what to ask anymore, since usual vocabulary turns pathetic when applied to the whole universe 8-[
Could we at least imagine, theoretically, what the edge of the universe and crossing it might be like?
