Light travels at 300,000 metres per second, about 1 million kilometres per hour, or about 671,000 miles per hour.
Matter, including humans, cannot travel at light speed as it would require an infinite amount of energy.
so Im just going to straight up say use google but also I'm going to say the speed of sound is faster than the speed of light and magnetism is was slower.
Fortunately, you'll never need to deal with that problem, since you'll never find yourself going at the speed of light.
Since no object with mass can reach the speed of light -- such an object can only approach that speed -- the question is meaningless.
No - you would be stopped BEFORE you reach the speed of light, by your increasing mass (among other things). As your speed approaches the speed of light, your mass would approach infinity, and it would require an infinite energy to actually achieve the speed of light.Note that the "speed of light" is not really about light. It is a speed limit of our Universe; some have described it as the "speed of causality".
The part about the spaceship going with the speed of light is not real. I don't understand the earlier part of the question.
If you are noted and apprehended by a law-enforcement officer, then you can be cited for going through the red light. Your speed at the time is irrelevant.
time dilates, space contracts, speed of light holds constant.
At a speed 212 000 kilometers per second you have a relativistic gamma of 1.41, and you will time 365 days of travel when travelling one light-year. You would think that effectively you were going at light-speed! An observer would see you going slower though, and would time your trip to over 516 days.
yes
No
Light is refracted by a discontinuity in the refractive index of the medium ... by going from one medium into another one where the speed of light is different.
You would see the other traing going by you at nearly the speed of light. This may seem counter-intuitive, but that's what happens. The speed of light is an immutable constant that does not care about your frame of reference. In the braydeon domain, nothing moves faster than the speed of light, regardless of frame of reference.
