Are there any theories or suggestions that there is a force that warps space-time in the opposite way that gravity does?
From my amature understanding of things gravity tends to legnthen space and slow time.
Are there any theories where "something" compresses space and speeds time?
How about travel near the speed of light?
I was thinking about this with regards to the expansion metric of the universe.
could the universe be expanding based only on the increase of gravity or antigravity ( as I am describing above )?
