That doesn't refute anything I said. You have to exceed
the speed of light or warp space/time. And I wrote:
Moving near speed of light
results in only going FORWARD in time.
Keyword: could. And that could
is dependent upon impossible parameters. Of course you could go back in time if you had a working wormhole time machine. But could you first create a working wormhole time machine?
