Nothing with a rest mass can travel at exactly the speed of light, it would take an infinite amount of energy. Light can travel at that speed because it has zero rest mass.
Earlier Answer below
So far, we don't know if a human can travel at lightspeed. However, it's easier to travel at the speed of light than to travel through time.
New Answer: The problem I always had with the term light speed is that speed is relative. We may be traveling close to the speed of light right now in relation to some other object in the universe.
No. Nothing with mass can travel at the speed of light.

You don't. The only objects that can travel at the speed of light are those that ONLY travel at that speed, like photons or gravitons.
Any massless "thing" like a photon and MAYBE a neutrino. NOTHING with mass can travel at the speed of light. Photons travel at the speed of light. The entire electromagnetic spectrum travels at the speed of light.
Neutrinos do not travel at the speed of light, but they do move very close to the speed of light.
No, it is not possible to travel at the speed of light in water. Light travels at a slower speed in water compared to its speed in a vacuum, which is about 299,792 kilometers per second. The speed of light in water is approximately 225,000 kilometers per second.
Nothing physical is believed to be able to travel twice the speed of light.
No. All colors travel at the same speed. It is called "the speed of light".
The only way to travel at the speed of light is to not have any mass.
You can't travel at the speed of light. It might be possible, in theory, to approach it, but not quite to reach it.
Yes, X-rays travel at the speed of light in a vacuum, which is higher than the speed of visible light. This is because the speed of light in a medium is inversely proportional to the refractive index of the medium, and X-rays have a shorter wavelength than visible light, allowing them to travel at a higher speed.
