All of the current scientific evidence disagrees with this. 1) There is a velocity such that you can go faster than gravity will be able to slow you down: escape velocity. So, it’s possible even without any new, weird physics. 2) The hubble constant shows that the universe isn’t slowing down, but the opposite: it’s accelerating. Physics doesn’t know why (see Dark Energy). It’s physically measurable that things farther away are accelerating even faster scaling with distance.
