Can you see inside a space ship moving at the speed of light?

Lets pretend I am in a spaceship and I am moving at the speed of light. There is a light bulb at the center of the ship. I understand that velocities don't simply add together, and the formula is v$_{3}$=$\frac{v_{1}+v_{2}}{1+\frac{v_{1}v_{2}}{c_{2}}}$. So the light would not be moving in your frame of reference. So if you look behind you, you would see darkness. But if you look in front of you, you could not see the light reflect off of the front walls of the ship, but couldn't you see the light that started in front of you? because that light would simply go toward you. I think if you looked behind you, you would see darkness. If you looked in front of you, you would see constant light. What do you think?

That's like saying "Let's pretend that there is an odd number that can be evenly divided by two..."; you'll be able to derive all sorts of strange and wonderful results, but they'll all be bogus because the premise itself is bogus.

In particular, the addition of velocity formula you're trying to use is derived from assumptions that are inconsistent with any observer moving at the speed of light, so if you try using it in your "let's pretend" scenario, the results of the calculation will be bogus.

A spaceship cannot move at the speed of light. You essentially are asking "what do the laws of physics say will happen if we violate the laws of physics?"

It's a nonsense question.

As I understand it, if you were moving at the speed of light you would not see anything at all because time would literally stop for you.

The whole point of "relativity" is that speed is always relative to some other reference. If you were in a spaceship moving, relative to me, at any speed less than the speed of light, you would see nothing at all different. Relative to the spaceship you are motionless.

Not only is that not right, but it's also not the result that you get if you try setting your speed equal to the speed of light in the various equations of relativity.

One way of seeing this: Right now you are moving at 99.99999999% of the speed of light relative to some observer somewhere in the universe. Are you experiencing even the least little bit of "time slowing down"?
