At nearly the speed of light? Yes. There's no practical way to do it, but it's obviously possible, neutrinos do so.
The speed of light in water is less than the speed of light in space. Only light can 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.
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.)
Probably not in five lifetimes! Light speed travel is a work of fiction, like in sci fi movies. No human will ever travel at the speed of light.
It is currently believed that this is not possible.
Not if you have any mass when you're not moving.
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,time travel is possible but it is somewhat difficult,as einstein said,"if an object travels with speed of light , the time near it would become slow and time travel wold be possible. All we need to is to produce such machine /spaceships that can travel up-to light's speed.
Speed of light is possible within a sphere.whereas controlled properties of the sphere can be introduced with technoligy in the year 2027.
Yes. Light particles travel at the speed of light, hf = mc^2; m=hf/c^2 = h/cw = 7.40E-51f.
Not by our current understanding of physics or technology.
