CERN Higgs boson God particle findings coming soon

[Everlong]

It is quite the breakthrough, though the announcement was more "we have it, I mean I think we do, probably...". Though it does look like it from the behaviour, only time will tell if it really is.

It is the final piece to the standard model puzzle, and if it proved to not exist then everything we knew about the laws of physics would be rendered wrong.

Space goes on "forever" because galaxies are accelerating away from one another as observed by Hubble.

This explains that galaxies are moving away from each other.

Not how space continues forever



Say you travel into outer space for thousands and thousands of light years and end up running into a wall, what's behind the wall?

There's different theories to whether the universe is infinite, or not. Nobody can answer it for certain as nobody has been to the edge of the universe (except the Doctor), so don't get your knickers in a twist about not knowing.

I may be wrong, but if the layout of the universe is flat, then its infinite. If it is concave/convex then it isn't infinite and is still expanding/shrinking (can't remember which way around it is).

As for what the universe is expanding in to, that's anyone's guess.
