you would go back in time? Or would you just being going really really fast? Just 60 years ago the speen of sound was the limit, and just 100 years ago we could not fly at all.
I think the really fast is true.

It could be possible, although I doubt if you could actually replace relativity with some other theory that could allow that. So for now it's not possible maybe in future.
I believe that because think about it before relativity we all thought that time was constant.
Plus even if we can't reach speed of light, we might be able to get close to it which can let us travel farther cause of time dilation. I don't think you could go back in time though.

Actually, better than saying, matter cannot travel the speed of light, it is more acurate to say the matter that our physical bodies are made up of cannot travel at the speed of light. However, the finer type of particle that light is made up of a different type of particle with substance. Light is a manifestation of electromagnetic force. Matter is made up of charged particles; due to the nature of atoms, being composed of a positively charged nucleus surrounded by electrons that are in motion. The nuclei in molecules also move with respect to each other. In other words, these are charges that are in motion, and everytime charges are in motion, there will be an electromagnetic force that will be changing with time. Light is an electromagnetic field that is oscillating. It is a wave that can be characterized by a frequency. But light is also a particle - its particle is called a photon and each photon carries a packet of energy that is proportional to the frequency. Matter can absorb the energy from a photon. So, while light is not made of what is traditionally called matter, it is made up of substance. However, unless we drastically altered our bodies to act as light does, in the manner of a photon (in wave form), which would probably require of breaking down all of our atoms and even so doing the other components could not keep up with the photons, if transported in the way that light is. So, traveling at the speed of light would be an extremely tricky process (almost certainly impossible). If you could, time would not change, but be suspended (from your own perception). Travelling faster would be an even greater impossibility, at least without destroying your atomic makeup completely, and who wants to do that?

It's not possible to travel faster than light, or even to go the same speed as light. As your speed increases, so does your mass. That means it takes more and more energy to keep accelerating. Once you got to the speed of light, your mass would be infinite, and so it would take an infinite amount of energy to reach that point, which is impossible. Can't do it, buddy!

If you are able to travel faster than the speed of light, you are able to go back in time, because you are getting out of the current time frame which you are in now.

Going faster than the speed of light is a probable outcome in the near future. However, I feel that the citizens of the nearby universe will show up and warn us to keep our reptilian warfare to ourselves.

yes,it is according to einsteins equation as well as properties of the light

Of course I believe it. Didn't you watch that documentary, "Superman?"
