is it possibal for a man to travle at the speed of light?

Question

can a person have a vehicle that is capable of travling at the speed of light?

Answer 1

No. Molecules with any kind of mass cannot achieve it, we'd have to be weightless, like photons.

Maybe you can ask photons how they did it.

Answer 2

It is a puzzle, but no, at this point no one can travel that fast...

Here is what is so puzzling... photons don't increase in mass even though they travel at the speed of light.

Also, apparently you would turn into a black hole if you were to approach the speed of light, infinite mass and zero surface area.

If we did travel at the speed of light, would we be able to pass through glass as a photon does since our size would reach that of a photon?

And... how would we adjust our course without becoming a splat on the inside of our craft?

Where would we go, even if we could travel that fast? And if Einstein's theory is correct about time, why would we want to excellerate ourselves into the future? By the time we returned, everyone we knew would be dead even though we would only have aged slightly.

Great questions, but meaningless since, we will never travel at that speed.

Answer 3

No. The closer you get to the speed of light, the greater your mass becomes. Eventually you're trying to accelerate something that weighs more than a planet and it takes too much energy. Anybody that gives you a different answer doesn't know physics and is living in their own little surreality wanting to imagine life as they'd like it to be.

Answer 4

I believe the theory is that you would have to be just below the speed of light at maximum (or you would require infinite energy).

My own view is that science is a point in time and, while I respect science, it has been shown to be insufficient (and even wrong) over the years ... who is to say that FLT travel will never be possible as we have only our current understanding to base this one.

Answer 5

No. As an object approaches the speed of light, the mass of the object will increase exponetially and the size will decrease exponentially. Upon coming to the speed of light, the mass would be infinitly big, the size will be infinitly small, and since E=mc^2 the energy it took is infinite.

Answer 6

There are theories based upon relativity that this may possible, but currently it is not. We have no means of achieving this currently. There is a theory involving black holes and worm holes called "Einstein Rosenbridge" that tries to explain how to leverage the physics involving both of these phenomena to create momentum upwards of the speed of light. But don't try that at home.

Answer 7

Tremendous energy is needed to accelerate a particle to the speed of light. Therfore there is no possiblity in near future to make a man to travel with speed of light.

Answer 8

Were you to be accelerated to the speed of light, the mass of your body would be converted into high frequency electromagnetic energy, similar to that of the electron. Would you exist? Only as radiation.

Time would cease to exist to you because it would become zero in relation to all other time values (you would become the universal time value all clocks relate to in order to measure change). Once there, you could never return back to what you physically were at one time.

Answer 9

once, an airplane designed to fly that fast almost reached it and it had a man inside. I believe that is the closest our race has ever gotten to the speed of light.

Answer 10

No, but it is possible to travel at the speed of life, as shown by Xzibit
