Is it possible for humans being able to travel faster than the speed of light?

Given our current understanding of physics, it is nowhere near possible to make anything the size of a human being travel anywhere close to the speed of light.

The reason for this can be found in Einstein's famous E = mc^2 equation.  In this equation, E is energy, M is mass and C is the speed of light.

What this shows is that you would need a huge amount of energy to make something go at the speed of light.  You would need an amount of energy equal to the mass of the thing you are trying to move times the speed of light squared.

This means that you would need an almost infinite amount of energy -- much more than we are able to generate.

no it is not possible. Could you imagine if you were able to go to the sun and back in just .8 seconds.

No. it is not possible to travel faster than light. Apart from the non-availability of any mode of transport that can travel at or more than the speed of light, there are other unimaginable problems that are likely to interfere with such travel. For example, the kinetic energy of motion in any object travelling at sped of light will result in doubling the mass of the object. We do not know in what way this doubling of mass will affect the humans body and mind.

Another iimponderable issue is that for a person travelling at the speed of light the time comes to a stand still. Thus a person may travel at the speed of light for a hundred years and return to the starting point feeling that not even a split second has passed. By this logic a person travelling faster than light should actually be feeling that he has returned to from the journey even before starting out for the journey. We just do not know the practical implications of all these theoretically proven realities. We just do not know what will happen to a person moving at the speed to light. Travelling at a speed greater than light is something that is just not understood by science today.

No there is no such thing as human traveling faster than the speed of light that is impossible.

not with the small energy we generate.
