speed of light?

Question

i was just wondering, if einstein travelled on a beam of light while at the same time shining a beam of light, the speed of light isn't like doubled, and c+c=c, so what would happen if say i were to travel on a beam of light shining a beam of light in the other direction, would there still be light emitting from the beam being observed by someone else? what would c-c=?

say im traveling on a beam of light and i flash my torch. then the speed of the light from my torch is: c+c=c

but if i shine in opposite direction then: c-c=???
please explain what formula should be used?

Answer 1

When Einstein asked himself this question, he realised, through extrapolation of Maxwell's equations, that any observer measuring the speed of a photon of light in a vacuum would always measure the photon's speed as "c". This is irregardless of the observer's motion. One does not add their speed to the speed of light. At that speed, time dilates and space [distance] warps and changes. "c" is the constant, not time or space. So, they would arrive at the same spped of "c" since their values would be different for t and d [or time and distance].

Answer 2

Consider the related situation, where he is traveling at a speed of c/2, then turns on the light. In this case, both he and the stationary observes will observe his light traveling at exactly c (regardless of the direction he shines it). This non-intuitive fact is what Einstein theorized, and special relativity was the result.

You cannot have him traveling c, since the time and space dialation equations would have zeros in the denominators.

Answer 3

sturdy adequate. Time does now no longer circulate slower for speedy gadgets. curiously to you, assuming you're able to be table certain, that element is passing slower for speedy gadgets. If there are no accelerations advantages - each and everything is continuously moving on the equivalent speeds relative to one yet another - then there's no thank you to tell who's moving and who's at rest. Now the twin paradox, which you style of paraphrased right here, has 3 accelerations in it. you start up from entertainment and accomplish an exceedingly severe speed. After a time, you turn around this suggests which you sluggish down, you momentarily end, and you speed as much as a severe speed returned. as a result you attain earth and sluggish to a stop. At each and each acceleration, you experience a force which the earthbound man or woman does no longer so it extremely is clean who's in circulation and who's at rest. as a result, you are going to return after 10 years a while strongest to seek for out that a a lot longer time has surpassed on the planet. Now celebrity trek assumes there is the thank you to experience exterior of the 4 dimensional area that defines the universe - the so-called subspace. in this subspace, relativity would not carry on with - that's exterior the universe extraordinarily a lot - so which you're able to desire to circulate from element to element in a finite quantity of time and, the time it takes to traverse the hollow as measured by skill of the starship's clock may be the time that elapses interior the universe - style of no longer likely although essential in case you're writting one hour long television episodes. there is not any information for the variety of holiday use in properly-liked man or woman trek.

Answer 4

u c, your "if" is wrong. Einstein can not travel on the speed of light. in this way the condition of a double speed light never been happened. the maximum speed of light is constant .

Answer 5

No. It would still be c. Whe observed, the speed of light is still c, regardless of the direction the light is emitted.

Answer 6

einstain could not travel in a beam of light...matter will start to convert into energy as it aproaches light. its against the physics for matter to travel at a speed of light....so light is only one like u said cant be doubled.
