Just noticed Philosoraptor doesn't know proper english. Well, the question is still interesting. What is your take on it ?
It is a rather interesting question. I would guess that if you are going the relative speed of light in a car and you turn on your headlights, I don't think they would be as effective. Just a guess.
This is why the Enterprise can only go warp 9.9. Once you are going warp 10, you are everywhere in the universe at the same time. TL;DR Lights are for newbs.
isnt light speed relative to your seed? so if your going the speed of light and you turn on the lights then they act as if you are not moving
In other words, the speed of light relative to you is always the same (c), regardless of what your own speed is.
Lame I could actually have calculated it cause we went over relativity in the last month of physics class. But I forgot it all by now D:
Well then, tell me what is the speed of light from those headlights, but for a guy who stays on earth, and watches the driver in his space-car run by ?
The question is moot, no physical object can approach the exact speed of light because its mass increases taking an effectively infinite amount of energy to get it to that speed. Warp that is often used in science fiction such as star trek, works on bending or shifting the space around an object rather than moving the object itself.
Not true, the universe expanded at a speed faster than the speed of light shortly after t=0, therefore it's possible. Impractical, but possible. Plus, it's theoretical physics... one can say the entire discipline is moot.
You are nitpicking. Philosoraptor keeps it simple instead of saying 'if you are extremely close to the speed of light'. The question still stands. At t=0, the universe wasn't a vacuum, so it doesn't pose a problem that the light could go faster in that medium than vacuum. And you don't add the universe expansion speed to the light's, since the universe is still expanding. E=mc² comes from theoritical physics, I don't think it's moot.
He hears the car go by after he's hit by it for the third time going around the world. And then he realizes he was hit after the fifth. I'm not morbid at all.
it takes an increasing amount of energy to go faster? the object expands as it gets faster? what if it uses energy collectors..that sucks in surrounding matter to use as energy..converts anything to energy...even sucks up energy. it expands and expands as it goes faster and faster..collecting even more energy each expansion... it approaches the speed of light..it expands to %99.99999999999999999999999999999999999999999 of the size of the universe. it turns on its headlights It sucks up the entire universe into one point..an egg if you will... then it goes past the speed of light... its not true nothing can go faster than light "One" thing can..with its headlights on new question tho... if the universe is sucked into an egg..where/what are the lights shining into/onto
Yes. No, the object contracts in the direction it is moving to, when seen from an outside observer. That's because we live in a 4 dimensional world comprised of 3 physical dimension and 1 time dimension. And they are equivalent. If you stretch one, you contract the other. Time stretches and length contracts when you move forward.
