I have a hard time accepting the concept of "space-time." To me, space and time seem like fundamentally different things. We can't move through time the same way we move through space.
The video says that time bends more than space. The time dilation we experience on the surface of planet Earth is around 0.00000001%. Is this insignificant bending of time enough to cause 1G acceleration?
General Relativity is a useful model. But if we follow it blindly, we might be ignoring other possible models.
