Again and Again :Revisited

This whole concept actually comes over me again and again. its pretty annoying that i just keep thinking about it all the time whenever it comes to me. but at the end nothing comes out of it.
ok i lasers can do it but we will require a really high power for it make any twists. Rather i was thinking of amplification of X-rays or gamma-rays which are really high powered for the stipulated emission.but its not much the scientific approach fancy be rather than logical consequence which lay behind time travel.Going forward is ok and its pretty much easy in concepts also.And not much of this will put us in any mind boggling puzzle, like all of it does when we talk about going back.
The usual way is to get a velocity greater than light, yeah but guess what,not allowed in this space. so the usual way fails,what we need to increase the velocity is either to cross same space in lesser interval(what we all do for it) or one thing that can be done is to cross larger space in the same interval,where the space is denser than the place ,we developed our vehicle and tested it to run at 0.99c. its either near a massive object,yes the black hole would be just nice.or a space twisting could also be done (according to some law i don't know) by these lasers.
