OK Leonardo I also can ask odd questions. If you were driving your space ship at a little faster than the speed of light - what would you see in your rear vision mirror! ;D

A GATSO speed camera. ;D

Whistler I see your point - I do ask odd questions, but your question is odder (is odder a word?). The answer to your question, however, will not come from me. Bit of a thicko when it comes to these, I'm afraid . Matt's answer made me laught, though. ;D ;D One could have also said "a galatic speed cop"

When light travels is it thousands of images as in a strip of Film. If it was and you travelled a light speed plus 1 MPH, would the vision in your mirror be of you a moment before? ;D

Very good question. I remember hearing a similar one many years ago, when Concord was first talked about.
Someone asked if the plane (Concord) can fly faster than a speeding bullit and a high-jacker was to fire a shot at the poilet how could the bullit hit him?
The asnwer is because everything is moving in the one space; the confines of the plane, the poilet will die.
Maybe you have a better response?

Slightly different, but I can assure you I spent 3 hours on a train discussing nothing! And try to imagine a different colour! Merry Chr..... ???whatever to you all! ;D

Chris. I have spent weeks talking without making any sense. ;D ;D Just re-read some of my posts! Happy Holidays to you too. Did you read what Mike Martin said about this whole Christmas PC thing on tfm? Priceless!

If you were driving your space ship at a little faster than the speed of light - what would you see in your rear vision mirror! ;D I think you would either see black void or what you see now (ish). The former would follow the theory of wave-particle duality, but for a specific instant in time and assumes the light source started the same time you did. The latter would take the existing light reaching you into account, and the "age" of the light would reduce as you go forwards. Using the Sun as an example which, IIRC, is 7 light minutes (~2.1x10 6km) from earth, so the sunlight you see now was actually generated 7 minutes ago. If you were to go FTL away from the sun, I think the age of the light reaching you would reduce. So at 10 light-minutes from the Sun, the light you're seeing would be, say, 9 LM old. I'm probably wrong, but it's been a long time since I even thought about this stuff. Thanks for bringing it up, though. Why not pose it to one of the may philosophical web fora or Usenet newsgroups? I did that with something similar about 10 years ago, and the group got itself into a tailspin for days. Love it. Wish I could remember what it was, though... The asnwer is because everything is moving in the one space; the confines of the plane, the poilet will die. That's relativity. IIRC, a scientist made himself famous by proving that point on a train with a cricket or tennis ball. Pity nobody had ever bothered to watch a bored kid on the train on a Saturday afternoon.

You make the assumption that your brain would be able to process the images fast enough to distinguish them.

Another assumption! Now you're getting the hang of it! ;D My university calculus tutor - also an actuary, luthier and man deeply in love with mathematics - once told me that of ALL the realms of science, mathematics is the only pure science: as only mathematics has facts as building blocks. All other disciplines (especially fields like physics) use theory as building blocks. (Excluding theoretical sub-sections of mathematics, of course). For some strange reason, every research scientist I've posed this to has gone a funny shade of purple and developed a stutter for a few minutes.

greetings. ;D i know this reply is abit late to the intial question. but i thought that i could put in what i think mite be seen while travelling at the speed of light. if travelling at the speed of light in a confined vessel and looking out side in any direction from within the vessel you would see light or energy which is one in the same. for at this stage in life we as humans cant detect or see UV rays nor will we be able to see anything at speed of light or possibly we mite be able to see creation at its first stages being at a higher vibration. well anyway thats my notion have a great week Regards Quantum Postman

Greetings and Welcome Quantum, Lets play with this some more. How fast would I need to be going in my rocket before the Rocket travelling at the same speed as mine, but behind me ceased to appear in my rear vision mirror
