Gravity and inertia
Currently NO, but there are a lot of scientist who won't accept that. Once upon a time it was thought that if you traveled faster than 40 mph the wind would rip your skin off. We know better know and someday we will learn more.
The possibility of Faster than Light Travel (FTL) seems to be bound up in the question of gravity; the last fundamental force of the universe we can't understand. Our understanding of gravity hasn't changed since cave men first noticed it. Galileo experimented with it, Newton figured out the rules of it; but we don't know what force carries it or even if there is a force.
I think that once we understand gravity will have a major clue to the universe that could lead us to an understanding of how to get around the speed of light limit.
Inertia is a powerful force that is often ignored. If you tried to make a sudden movement at FTL speeds the inertia would be enough to slam the crew against the bulkheads so hard they would be converted to a fine jelly. We don't know what causes inertia, but until we find a way to control it we won't be able to doge space debris at super-luminal speeds. I think that inertia and gravity are related since both are properties of mass.
According to Einstein, and it has been proven on the space shuttle and with aircraft, the faster you go, when approaching light speed, the slower time passes, your length in the direction of travel shrinks and your mass increases. That means as you get toward the speed of light your length is almost zero, your mass is almost infinite and time has almost slowed to a stop. How do you keep accelerating when the object you are pushing is getting increasingly heavy as you go faster? On a human scale we don’t notice it, but on a Star Trek scale it becomes a major factor. Star Trek invented inertia dampeners to handle the problem, but that is pure fantasy we have no idea how to do it.
Once we gain an understanding of gravity and inertia I think that our physics will have improved to the point where we can start to understand the complexities required to travel faster than the speed of light; even if it is possible. We know there are far more dimensions than the normal 4 we deal with each day so understanding higher dimensions could be an important step; but we aren’t built to handle such things. We can’t even understand what the higher dimensions are or how to access them. Since we can’t determine the source of gravity it may be that the force is sourced from a higher dimension. If we can understand any of this then we can probably get a better clue to understanding what is going on in the universe.
There is an old maximum; the more we learn, the less we seem to know. As we learn more and more about our universe there seems to be and even larger amount of things that we need to learn. Like the secret of dark matter and dark energy; are they related to gravity? What exactly are these items and can we use them?
We need some fundamental break throughs in science to even approach the point where we can understand what we need to know to grasp the possible solutions to the riddle of FTL travel. For that we need to keep plugging away at science and accumulating a growing understanding until some genius like Newton, Einstein, or Galileo enters the picture and you can’t predict anything like that.

Depends on how you observe the traveler and define travel. As one travels faster and faster, the traveler gets more and more out of sync with the timeline he/she was previously in. Days of near-light travel can result in someone being more than that many days into the future when that traveler comes to rest again. There is also the possibility of space folding (warp) technology. This involves making two distant points in space next to one another, traveling x number feet or miles forward, and then letting space unfold again. The ship only traveled a x feet or miles, but once space unfolds, the ship is lightminutes, lightdays, lightmonths, or lightyears from the starting position. To make it easier to understand, you can also imagine two dots on opposite ends of a piece of paper and then making the two points nearly touch. You would only have to move a pencil point a millimeter and then let the paper unfold to travel the length of the paper. Both of the above means take more energy than we can figure out to provide, but it's not outside the realm of possibility

It may be possible to set up "wormholes" or extra-dimensional travel methods which could let you arrive at your destination the moment you left your departure point, but there is no guarantee that your experience of the time in transit would be any less than if you had gone the long way round - in other words, If you travel to a planet near Alpha Centauri by wormhole, the universe might experience your transit as instantaneous, but you might take years in your personal experience of travelling through the wormhole, and arrive as an old man.

No, it would defy the known laws of physics. We would have to expel matter in the opposite direction that we wanted to travel. We cannot and will not be able to expel something faster than a beam of light or a charged particle. They can't travel faster than the speed of light so neither could a spaceship.

I think that it would be possible to go faster than the speed of light if you are going downhill. I feel that in 145 years, 3 months, 10 days, 5 hours and 15.36 minutes man will go faster than the speed of light.
Seriously though, if you were going the speed of light and entered a black hole, I think you would be accelerated and go faster than light.

I don't think it is possible/attainable to go the speed of light.
The stress on the human body would be too great just trying to get to that speed.

No - not even light can travel faster than the speed of light.

Hello Dear
Yes it is very much possible.
But it will take years to take place, physically.
And I belongs to the thought that man should also take help from religion or sipiritulism, too.
The Quranic studies will reveal many ways to happen in the future.
A practical and good muslim performs his life according to science.
But there are a few practical muslims are present now. But who are actual muslims they are really live their lives scientifically and in a kind way to the huminity, really.

No I don't think it is possible. If we try to go the speed of light then the jet and the human inside it will tear apart because of the intensity of the speed.

Theory says it is impossible, so far...
Some minor "cracks" are appearing in Einstein's theories, but it'll be a long, long time before we, as a civilization, collectively, can surpass the limits to our physical universe expressed by him and those who have confirmed his ideas through scientific experimentation.
