Do we really need gravity to make the universe collapse again.
How about this.
what if beyond the universe there is that force which has a tendency to try and push against our universe ,a force all round our universe that puts pressure on it to try and force it back where it came from.
example let air out of a balloon it will collapse.
due to the pressure outside.
same principle could apply to our universe.
