No reason, if you have enough energy you can.
For 'enough' read 'infinite'.
Prove it.
How much do you think is needed then?

.
E = 1/2mv^2, v = c = 1, m = 1, so in the units I've chosen, 0.5.
You can convert to SI units if you wish.

E=1/2mv^2 is NON-relativistic. Relativistic it would be E=gamma*m*c^2.
Gamma
would be
1/(sqrt(1-v^2/c^2)) 1.
You really dont understand physics my friend 
Floris
Oh, but do. I understand quite a lot of hogwash too.
When you have proof that "light is always propagated in empty space with a
definite velocity c which is independent of the state of motion of the
emitting body" then you'll be able to claim to know physics and I don't.
Until you have that proof, I'm afraid it is you that really doesn't
understand physics, or mathematics either. You bandy your gamma around as
though it is of consequence. It isn't. It was derived from an equation of
Einstein's,
1/2[tau(0,0,0,t)+tau(0,0,0,t+x'/(c-v)+x'/(c+v))] = tau(x',0,0,t+x'/(c-v)),
and the 1/2 was pulled out of nowhere, purely assumption. If you can prove
that 1/2 was other that I state, then you'll be on your way to showing me
your gamma.
Relativity isn't physics, relativity is hogwash.
Oh, and by the way, light is source dependent in interstellar space.
Recurrent novae aren't stars that blow up, settle down to normal, then blow
up again.
What they actually do is go around in long period orbits, shining light in
all directions as stars do, and the light that comes to us arrives with
their motion added. This means that for some stars nearly all the light from
a complete orbit can arrive here at once, giving the appearance of a very
bright star for a short while. This causes astronomers to get excited for a
short while, then, when the star settles back to being dim and ordinary once
more, forget all about it. of course, you can believe they blow up
repeatedly if you want to and call it physics that I don't really
understand, but I understand it all too well. You might as well tell Kepler
he doesn't really understand the Ptolemaic epicyclic movement of the planets
while you are about it.
And another btw: the energy required to accelerate something to c is very
small indeed. Photons do it all the time. :-P
