hey come on man... its impossible for humans atleast cause you will be reduced to ashes at such high velocities before you reach the other place.... any one have a clear answer for this.... come on write it here...

actually, this is impossible..
the reason, let's take any object with mass M... then, making it move as fast as the speed of light, you must have an energy equal to... (M(300,000)^2)/2
which technically can't be achieved because we, humans, will never find an energy source that can suffice that amount of energy...
in short, there will never be an energy source that can make an object move at the speed of light...

In free space without any air friction velocity by itself does not generate heat. Consider a modest acceleration of 1 g. From rest it will take only about 200 days to reach the velocity of light at an acceleration of 10 m/sec/sec.
Provided one has a long enough distance even free fall in a gravity well can generate quite high velocities.
One has to deal with mass enhancement, time dilatation and various such relativistic effects.

Nothing with Mass can travel at the velocity of light, as it would take an infinite amount of energy to do so.
The only things that travel at the speed of light are EM Waves (such as Visible Light, X-Rays, Radio Waves etc.)
And also the postulated carrier of the gravity force - the graviton.
Some particles such as Neutrinos (which have neglible mass) can get close to the speed of light, but never quite reach it.

No, nobody would be reduced to ashes if everything else is also travelling at the speed of light. Suppose the earth is travelling at the speed of light then one can walk or run and total velocity may even exceed to that of light. Do we really know whether things are or are not moving alongwith the waves that may move even at speeds greater than that of light. The space may be much larger than just what one imagine. It may have a number of horizontol or vertical layers and our imagination may confine to just one single such layer. It is all relative as one can safely travel at any speed if and only if everything else travel at the speed of light.

The speed of light is the fastest anything can travel in a frame of reference. The frame of reference foe us is the black hole at the centre of the galaxy. The black hole creates a magnetic field which may dictate the speed things go. The stronger the field, the lower the speed. Build a spacecraft with strong enough magnetic engines and you could create Your own frame of reference and go faster than the speed of light. The problem I see is inertia, maybe 5 months at 1g to achieve these velocities. The energy would come from the fusing of Hydrogen to Helium and then to Oxygen, as the universe is 99% Hydrogen

Yes its possible.... at least theoretically.
Nothing with mass can travel at the speed of light but yes... space can contract and expand at, or even more than the speed of light. It is called travelling inside a space bubble. In the bubble offcourse, you wont be travelling at the speed of light , but the bubble itself can move at or more than the speed of light.When the space behind it contracts and that in front of it expands, the bubble gets sucked in the front direction.
So, the real constrains are not the laws of physics, but our ability to develop the technology to travel safely at the speed of light.

E=MC^2 . this shows that as u approach the velocity of light your mass will increase. At the velocity of light your mass will be infinity and u will turn into a black hole.

Nope not ever possible..
let it just remain in the theorems of hawkings!!
& forget bot gettin in a real time machine.. coz acc to the theorem if we can travel with the speed of light we can travel in time...

It is not only for humans, any object with mass* cannot.
