if we can tavel at speeds above light speed in the future why should we not be able to travel back through time?

It will not be possible in the near future or any other time.

Time travel to the future is easy, time travel to the past is hard.
Time travel to the future is easy. Here's what you do. Get a ship and go very fast, maybe orbit a black hole (from a safe distance) a few times, or get very close to the speed of light. The faster you go, the faster time passes. When you return to Earth, you might be 10 years older, but Earth will be thousands of years in the future.
Time travel to the past is more difficult, it requires either traveling slower than 0 or using wormholes, black holes, and other very complex mechanics we don't even begin to understand.

First off... it's Stephen Hawking...
Next, yes time travel has been theorized to be feasible, but improbable as you would need incredibly enormous amounts of energy and probably have to travel close to the speed of light... therefore you would need an infinite amount of mass to get you there...
And third, Hawking is an astrophysicist, not someone who really worries too much about time-travel. He deals more with expanding our knowledge of the Universe. Mostly how it pertains to black holes and string theory. Read " A Brief History of Time" or one of his other books and you'll get an idea of his actual work.

Well, in the quantum theory, it is said that you can speed up time enough to light speed that it will go into the future, but the theory I tend to agree with is that you can't slow down so much that you actually go backward in time. You can either go faster or the same speed, but not slow enough to go backward in time because even if you were to run backwards at the speed of light, time would still see you as plummeting forward through time and not backward.

Yes. I am currently traveling forward in time on a scale of 1:1.

I think he said it was possible, but improbable. U would need the same amount of energy that the sun has and will produce in it's entire life

NO it is not possible you will have to break alot of rules of science nature and even mathematics

According to "today's knowledge and technological level" it is probably remote.
But what do you know about "Andrew Carlssin" 's story?????
Put the name in your search machine and surf.
It may be hoax.....
What if it isn't???
