Time travel could enable star travel

Time travel could enable star travel. Time travel is now claimed to be possible per Ronald Mallett of the University of Connecticut. This is explained in the documentary "How To Build a Time Machine" He believes it is possible to twist time using lasers.

However there are two important limitations. It can only send messages (data) that could not go back to any time earlier than when the time machine is first turned on. These limitations may not block star travel.

Star travel could be done with the help of time dilation. The closer the traveler gets to the speed of light the more time, for the traveler, slows down. This allows the traveler to seem to travel faster than the speed of light. In reality millions of years could pass for an outside observer while only weeks pass for the traveler. The problem is not in the outward journey but in the return to the same epoch. The time machine would solve this problem by allowing traveling back thru the dilated time to the starting point. It would not be necessary to go back beyond the starting point.

As to data only, what would actually be sent if teleportation were perfected? Would the exact atoms have to be sent, or only the information (data), necessary to reconstruct the original.

I wonder whether the time machine could be carried on the starship or if it would have to be kept running near the point of origin.

Quantum gravity from singularity

Could all of the universe be Quantum entangled as a result of the fact that it was once all of the same singularity (which underwent the big bang). There could be a continuing connection where a change in one part of the universe exerts a influence towards similarity in all of the universe.

Could gravity be a result of this?  An influence towards similar location would result in an attempt to be in the same place. Since there is no center of the universe this might manifest as universal attraction or gravity.
