NoName Posted June 6, 2012 Posted June 6, 2012 And what would happen in a universe without time or space as the case may be. Well I am just a curious 15 year old so please don't make fun of me if I am asking silly questions.
Airbrush Posted June 6, 2012 Posted June 6, 2012 No time or space? Any matter? If there is matter, there will be time and space. If not, nothing happens.
timo Posted June 7, 2012 Posted June 7, 2012 And what would happen in a universe without time or space as the case may be. The universe is, I believe, usually defined as the space and time and its matter content. In other words, you are asking about the looks of the universe in the absence of the universe. Note that asking about the universe in the absence of space and time (as you just did) is different from asking about the universe in the absence of matter (which you actually seem to mean). The question how the universe looks like in the absence of any form of matter (or radiation) content is a different one. First of all, the complete absence of content raises the question how you could sensibly define anything (like location, temperature, ...). If you ignore the question and simply put zeroes for all matter contributions in our current model for the universe, then I believe you were to end up with a static universe, i.e. just empty space that doesn't do anything (neither shrink nor expand). I have, however, not explicitly performed this calculation. So take that answer with a grain of salt. 2
Airbrush Posted June 7, 2012 Posted June 7, 2012 I am talking about a unverse devoid of matter. That would be a nothing universe.......until there is a big bang. 1
