This modded Corvette can do 0-60 in one second

186000 miles per second / (60mph/sec) = 3100 hours

So if we kept this thing running for 4.5 months, we could achieve light speed.

This is 30 year old tech. It's not that hard...

Its not a corvet, its a drag racer with a plastic body.

How much fuel does it burn per second?

Add the fuel's mass, reduce acceleration proportionately, 0-60 will probably take 1 year.

@OP – here's why not.

Let's say you hook an accelerometer up to your spaceship and tried to measure your velocity that way. You would perceive that you never stopped accelerating (assuming you had infinite fuel); and thus, your accelerometer would register, falsely, that you had at some point broken the lightspeed barrier. If, however, you tried to measure your "absolute" velocity by measuring the speed of light relative to your craft, you would find that you were in fact perfectly stationary, not moving at all.

This is because all velocities are relative. It is impossible to get any closer to the speed of light, absolutely speaking. You can only achieve *relative* velocities close to the speed of light; and because of time dilation, an outside observer would only perceive you getting closer and closer to the speed of light, without ever actually reaching it, even though you were accelerating at a (subjectively) constant rate. This is because (relative) velocity does not add linearly, as Galileo assumed; rather, it is the inverse hyperbolic tangent of velocity which adds.

It's one of those weird, counterintuitive things about relativity that just don't really seem to make sense to human minds, but are somehow true. We've confirmed these things experimentally.

The universe is stranger than we can imagine.
