Yes. Light particles travel at the speed of light, hf = mc^2; m=hf/c^2 = h/cw = 7.40E-51f.
by converting one into light particles.
It isn't clear at all what you mean. In any case, it isn't possible to travel at the speed of light - except for specific particles, such as photons (pieces of light), which can ONLY travel at the speed of light.
No. Alpha particles are helium nuclei; such nuclei have a mass, and can therefore NOT travel at the speed of light.
The Universe seems to have a speed limit, called the "speed of light". This speed limit is approximately 300,000 kilometers/second. Light travels at that speed; so do other electromagnetic waves. Gravity waves are believed to travel at the speed of light as well. Finally, it is possible for particles to travel at a speed very close to the speed of light. Neutrinos tend to travel very close to the speed of light; also, cosmic rays contain very high-energy particles which also travel very close to the speed of light.
Because at infinite speed, it's mass will become zero, which is not possible as it consists of photons which are not massless particles.
The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
There are some particles that travel at the speed of light - mainly, the photon (the particle that makes up light), and the (hypothetical) graviton. No particles are known to travel faster than that, and it doesn't seem likely that this is at all possible.
With current technology, it is not possible to even come anywhere close to the speed of light. For example, traveling at 1/10 the speed of light is still science fiction. On the other hand, for anything that does NOT travel at the speed of light, it is impossible to actually attain the speed of light. In theory you might get close. There are some particles, such as photons and the hypothetical gravitons, which ONLY travel at the speed of light.
You can't travel at the speed of light. It might be possible, in theory, to approach it, but not quite to reach it.
The only way to travel at the speed of light is to not have any mass.
Faster than light travel is possible, but only for small particles like tachyons. Travel for humans is virtually impossible unless a way is developed to convert humans to particles. It has been proven improbable, but technology may prove it possible in the far future.
What is the speed of light? About 300,000,000 meters per second - enough to travel all around the Earth 7.5 times in one second. Can anything travel nearly as fast? - Yes, in particle accelerators particles are regularly accelerated to over 99% of the speed of light. According to current scientific understanding: (a) it is not possible to transfer matter, energy, or information faster than the speed of light. (b) An object that regularly travels at a slower speed can't be made to travel at the speed of light - it can only approach it. (A photon, that is, a speed of light, can only travel at the speed of light.)
