# lightspeed vision

## Recommended Posts

dunno if this has been covered before ..

lets say your sitting in a train ... the train is moving at the speed of light and there is a mirror in front of you ... you cant see your reflection because the light that bounces of the mirror would have to travel at twice the speed of light to get back to your eyes ... soo what do you see in the mirror ...

and another question ... can you even see the inside of the train, or your hands and feet when travelling at that speed ... cause it seems all the light in the train should be moving the same direction or something like that ... so it cant hit your eyes for you to distinguish anything ...

Yes. And there is a search function.

... the train is moving at the speed of light

The situation is moot; this is not a valid reference frame. Your premise violates physical law, so you cannot draw any valid conclusion using other physical laws.

im not a physics person ... i just read up on what im interested in soo i dont know how else to ask the question ... cant you just give me a hypothetical answer or an opinion ?

You would see yourself' date=' with no distortion. The light will travel relative to you at 'c', just like it would if the train were stationary.

Yes, again everything would look normal. However, if you look outside the train, the will see some weird shit!

If the train you were on was going a very high percentage of c, like 99.99% c, you would see everything normally within the train.

However people stationary relative to the train would look in the train and see things moving extremely slowly, while you in the train would also see people on the outside moving extremely slowly. There would also be lenght contractions, and disagreement between obververs about the mass of objects.

Go in your bathroom and look in the mirror. Now, realize that, relative to some object moving the speed of light (or close to) away from you, you and the mirror are moving at the speed of light. Things still look normal though.

Relativity hints at the fact that particles are simply bound energy, light. We are part of the fabric. If you approach a light source at half the speed of light, and measure light-speed in your frame, it still measures "c" but you encounter a blue-shifted higher frequency. You just have to hang out with this, it is not part of our everyday perceptual framework.
