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.
The only way to travel at the speed of light is to not have any mass.
At nearly the speed of light? Yes. There's no practical way to do it, but it's obviously possible, neutrinos do so.
by converting one into light particles.
To travel at the speed of light, you would need to have an infinite amount of energy, which is currently not possible with our current technology and understanding of physics. Additionally, as per the theory of relativity, an object with mass cannot reach the speed of light.
The limitation of science and technology is the ability to travel at the speed of light and in order to travel at the speed of light we would need to find a way to not interact with the higgs boson. Since we are interacting with the higgs boson we can not travel at the speed of light.
It is impossible.
You could try becoming a ray of light.
The only thing that travels at the speed of light, is light. Light is also said to have no mass, therefore the only way for something to travel at the speed of light is for it to have no mass.
No human or machine can travel the light of speed. No matter how close you are to the speed of light if you have all the thrust in the universe you cannot get going past the speed of light. The familiar notions of absolute space and absolute time independent of your relative motion must give way.
Actually no. Light may travel to you at the speed of light but once it strikes your retina the process of seeing slows all the way down to bio-electrics which is a poor contender compared to the speed of light.
Probably not (exception - figure out a way to become a pure energy being).
The Milky Way galaxy is about 100,000 light-years in diameter. If you could travel at the speed of light, it would take approximately 100,000 years to cross from one side of the galaxy to the other. However, this is a theoretical scenario, as current laws of physics suggest that nothing with mass can achieve the speed of light.
