Crossing the speed of light....

Its' a small question...but a very important and one of the most-frequently asked questions...Why can't we travel at the speed of light?

Energy limitation /or/ because we have mass, while light doesn't.

"Particles that have mass require energy to accelerate them. The closer to the speed of light you get a particle, the more energy is required to go faster. This is because the particles themselves get more massive in proportion to the increased velocity. In short, the faster you go, the heavier you get.

Thanks to this inconvenient truth, if you wanted to accelerate a single electron to ‘light speed’, you would need an infinite amount energy due to the electron becoming infinitely heavy. There isn’t enough energy in the entire universe to propel just a single electron to the speed of light."

Guilherme, why don't you send me a friend request on Facebook....?...We'll speak a lot on such scientific matters.....Thank You for your answer although!...Thus you say...if we limit the substance called mass even in humans to Zero...we could indeed travel at the speed of light....Right?....'Zero' mass is the key...that's the reason a shadow travels at the speed of light.....

Souvik,

There is no such thing as "zero mass". We, physical creatures have \(\text{mass} > 0\). Even a very small mass particle, such as an electron, "would need an infinite amount of energy" (remember the formula \(F = m \times a\)).
