Without boring you here is the reason:

E=MC²

To a layman what this means Energy (E) = Mass(M) X Speed of Light squared, so it would an infinite amount of energy to get anything with any mass at all (meaning everything that exists from space ships to mole crap) going anywhere near the speed of light. Get it? INFINITE Energy (there is no such thing, never will or can be such a thing).

See post #18. Even Einstein was wrong sometimes.

Besides, 1/10th light-speed gets us to the nearest star in 50 years or so, and pushing a star-wisp type probe to those speeds should be within reach even now.

And you are already wrong, because we have hardware out past the heliosphere, in interstellar space.

Uh, BZZZZT!, wrong answer. The equation you WANT is the Lorentz-Fitzgerald Equation

Basically, length contracts and mass goes up as you approach light-speed, with mass approaching infinite as you approach the speed of light. Most of these effects aren't really noticeable until you're at ~99% or above of lightspeed. But as mass goes up, the energy required to accelerate it to even higher speed goes up exponentially. . .
