If I traveled the speed of light and had a flash light with me so when I turned it on would the light comming off the flash light be traviling the same speeed as me or 2X faster that the origianal speed of light ? And would it even be called the speed of light any more?
The speed of light is constant in all frames of reference. To you, the light will appear to be moving away from you at the speed of light, just like it always does; it will not look like anything special. To someone at rest (the person to whom you are measuring your relative speed to be the speed of light), you and the light will appear tied, the light will be moving at the speed of light, as so will you. But it is important to remember that no object with you (that includes you and the flash light), can every travel at, or exceed, the speed of light. Doing so would require an infinite amount of energy...and in the entire universe there is not an infinite amount of energy.
Oddly enough, the same speed. Your hypothetical example is unreal of course. But say you were on a plane going 300 MPH. you shine a flashlight out the front window. The beam of light is travelling c, not c+300 mph
The light would be traveling at the same speed as you are.
practically,this is impossible theoretically,if you traveled at the speed of light,the light from the flashlight would go 180000 mps because of special relativity. time and space[and mass]dilate relative to speed so,at the speed of light time and space would dilate in a way that light would move at the same speed as when the flash light is at rest
sturdy sufficient. Time does no longer circulate slower for speedy gadgets. interestingly to you, assuming you would be desk bound, that element is passing slower for speedy gadgets. If there are not any accelerations advantages - each little thing is constantly shifting on the equivalent speeds relative to one yet another - then there is not any thank you to tell who's moving and who's at rest. Now the twin paradox, which you sort of paraphrased right here, has 3 accelerations in it. you initiate from entertainment and attain an extraordinarily extreme velocity. After a time, you swap around this implies which you slow down, you momentarily provide up, and you velocity as much as a extreme velocity lower back. for this reason you attain earth and sluggish to a stop. At each acceleration, you journey a stress which the earthbound guy or woman would not so that's sparkling who's in circulation and who's at rest. as a result, you are going to return after 10 years some time maximum sensible to look for out that a lots longer time has exceeded in the worldwide. Now star trek assumes there's a thank you to journey exterior of the 4 dimensional area that defines the universe - the so-universal as subspace. in this subspace, relativity would not persist with - that's exterior the universe exceptionally lots - so which you need to circulate from element to element in a finite quantity of time and, the time it takes to traverse the hollow as measured by employing the starship's clock could properly be the time that elapses in the universe - style of no longer likely in spite of the incontrovertible fact that integral in case you're writting one hour long television episodes. there is not any info for the style of shuttle use in popular guy or woman trek.
