I thought, how big? The BB even on a smaller scale could blow up the earth.

EDIT: someone mind explaining why we thought it was impossbe for something to go faster than the speed of light?

Because when the speed of light is surpassed a huge wave sound is made.. feels pretty much like an earthquake mixed with a tornado.. but its not "impossible" to go faster than speed of light.

You've got to be kidding me
That is the sound barrier ffs not the "light barrier" (velocity c in lame terms )
As you approach c (the speed of light), matter starts getting converted into energy. And there is a certain equation by Einstein which gives mass of a body at the speed of light. m(at v) is m0 (mass at rest)/(square root of a term)
It shows bodies can't go faster than the speed of light. And that equation is the reason.
The square root term is something like sqrt(1-v/c)
where c = speed of light and v = the bodies' velocity.
If c<v, sqrt is positive and mass is finite. For most velocities humans travel at, v<<<c so v/c~0 (approximately equal to zero)
Hence m is almost equal to m0.
As v->c (tends to), v/c -> 1 and we get m(v) > m(0)
If you take v=c, m(c)=inf.

Thus it is said that mass gets converted to energy (dunno why mass increases though )
If you think of v>c, your mass becomes an imaginary term haxx

Anyway, there are particles which are known to travel faster than light Wiki ftw

EDIT: Dodgy
