The very same thing was said about breaking the speed of sound.
It was done, and still is.
But they two are totally different things. The speed of light is a variable consistent with all sub-atomic and physical reactions in the universe. The speed of sound is simply moving faster than sound propogates through our atmosphere.
There are a number of quite valid theories as to how the speed of light can not only be reached, but also exceeded.
They must be fringe.
Sort of like a "hyperspace" fold of sorts where one is not traveling in a line or curve to get from point A to point B. More of "folding" space and hopping over. That's one theory. I got more.
That's still not exceeding the speed of light; it's simply covering more distance than travelling at the speed of light would allow.
You know how something travelling faster can impact as though it had more mass? For instance, a penny being thrown at a passerby could tickle him, but a penny thrown faster than the speed of sound could kill him.
There are other reasons why faster-than-light travel is impossible.
For one, the intertial mass of an object increases with it's speed. And because you need to apply
more energy to something 'heavier,' you would need to find more power to fuel increasing the speed of something moving at 90% the speed of light.
And after that, you would need to find enough power to move something to 91% of the speed of light.
Read about Xeno's paradox, if you don't know it (You probably do).
In short, in order to propel something and have it move at the speed of light, infinite energy would be required. It's not a matter of finding this energy; it's simply a physical impossibility.
Due to the Doppler effect (Demonstrated by the way you can tell that an ambulance is moving towards you or away from you), objects in the universe moving away from the observer (Us on the earth) tend to redshift. The wavelength of the light they emit increases while the frequency decreases.
Objects moving towards us have the opposite effect.
An object moving
towards us at the speed of light would emit light of
infinite frequency - the
blueshift would be infinite due to the amount of power needed to accelerate it, and the power would destroy everything that it reached.
