Let's say you are in water where light travels at a speed of [tex]\frac{c}{n_w}[/tex] where [tex]n_w = 1.5[/tex] and you travel faster than this speed - what happens? What do you see?
whozum said:The laws of the speed of light apply to any medium, not just vacuum. If the speed of light were 1m/s in a certain material, that speed would be unattainable in that same medium.
1 said:you will die, no seriously, you will. you will be of infinite weight and will require infinite energy to move, and will die. talk about letting yourself go. it is impossible to go faster than light, no matter what (unless you are a universe that just happens to be expanding, then, i read, it is possible. i don't know exactly how, but i will trust my reading skills

ZapperZ said:This is a faulty application of relativistic mass. Take a look at how it is applied with respect to ANOTHER observer. Pay attention to the fact that a person does NOT see his/her mass increasing since he/she is always in the same proper frame and does not observe his/her mass moving.

ZapperZ said:Yes, it can. That's the whole principle behind the Cerenkov radiation - charged particles moving in a medium at a faster velocity than light in that medium. Huge detectors are used to detect neutrinos this way.

No, it wasn't. It was completely wrong.whozum said:Then my answer to the OP is more or less correct. :D
whozum said:Isn't it restricted by the same reasons its restricted in vacuum?
whozum said:Isn't that more of an exception than the rule?
whozum said:Wont argue with you. How do objects go faster than the speed of light in a medium?

Please refrain from responding to question unless you are quite sure you are giving a correct answer.

The speed of light is approximately 299,792,458 meters per second, or about 670,616,629 miles per hour. It is the fastest speed at which all things in the universe can travel.
According to Einstein's theory of relativity, nothing can travel faster than the speed of light. It is considered a fundamental law of physics and has been repeatedly proven in experiments.
If an object could travel faster than light, it would violate the laws of physics and cause a paradox. Time would appear to go backwards, and the object would have infinite mass and energy, making it impossible to exist.
No, there is no evidence of anything traveling faster than light. In fact, all experiments and observations have consistently shown that the speed of light is the maximum speed limit in the universe.
Based on our current understanding of physics, it is highly unlikely that technology could ever advance enough for us to travel faster than light. However, it is always possible that new discoveries and breakthroughs could change our understanding of the laws of physics in the future.
