But place should change too...but because the whole universe is moving, if you calculate the length of time, you should be able to "jump" right to a star some billions of years away, just because of the property of the moving universe, and changing time....
interesting not?
You forgot about a few things though, gravity permeates through all dimensions, even time. In
classical physics, it is not truly a force even though we call it one (the energy does not originate from particles) but what Einstein called gravity a space-time curvature. Even if time were to stop you wouldn't be weightless due gravity no longer becoming an affecting "force". Just as you said, the entire universe is moving. That alone is not attributed to gravity but also dark energy which causes the universe to expand at an ever increasing rate, however, it has been postulated by scientists that it is a property of space and also permeates through all its dimensions. If gravity or dark energy did originate from simply just particles that are similar to light then yes, you would be relocated due to the many forces affecting the universe during the "time-skip" and be sent just as you have noted.
Time travel does exist in classical physics as well, it is called time dilation which can arise by traveling near the speed of light or through the difference in gravitational potential (the lower the potential the slower time will pass) between different locations (this is why you hear astronauts in space aging more slowly than those on earth). In technicality we all experiencing time dilation naturally through the different attitudes and therefore different gravitation potentials making all of us "traveling through time" at different rates (although the difference is
extremely small in this case). If the gravitation potentials of earth could be amplified many times over (and of course you would probably turn to mush if you tried to use this method) it could appear as if time was fast forwarded relative to earth. Mind blowing isn't it? Traveling back in time is a different matter entirely and many scientist do not believe it is possible without breaking the laws of physics.
