Larry Phischman say: Because the laws of physics as we currently understand them say there is no way to go faster than light. There is a tendency in the scientific community, particularly among baby-boomers, to assume that our current understanding of physics will always be valid. The devotion to the standard model, quantum physics, and the laws of relativity is about as close to religious devotion as men of science and reason get. And just like the religiously devout, they either ignore or go through mental gymnastics to explain away information that conflicts with their "faith".

Sciencenut say: I'm a little surprised that no one has brought up the Alcubierre drive for faster than light travel. And then there are those notorious wormholes we hear so much about. I recommend that you do a Wikipedia search on these topics.

Budder say: Nothing in the universe can travel faster than light. Anything with mass can't travel faster than light. Sound waves have mass; therefor, engines and things like that can surpass it. However, the speed of light (or the speed of a photon) has no mass at all. Particles move through what scientists call "the Higgs field". As a result of this interaction, particles get mass. Different particles interact with the Higgs field with different strengths, which is why some particles are heavier than others. Photons (or light) move through the Higgs field, but don't interact with it at all. Which is why light is massless and nothing can move faster than the speed of light (186,282 MPH or about 1 billion KPH).

Marc say: You obviously are either intellectually impaired or haven't made it past the 8th grade: as something speeds up, its mass increases compared with its mass at rest, with the mass of the moving object determined by multiplying its rest mass by the Lorentz factor. This increase in relativistic mass makes every extra unit of energy you put into speeding up the object less effective at making it actually move faster. As the speed of the object increases and starts to reach appreciable fractions of the speed of light, the portion of energy going into making the object more massive gets bigger and bigger. This explains why nothing can travel faster than light – at or near light speed, any extra energy you put into an object does not make it move faster but just increases its mass. Mass and energy are the same thing.
