Default speed of light

okay I am drunk but I want to know why the fuck to go faster then the speed of light have to take an inf amount of energy. Shit its fucking waves like sound just faster. If it takes an inf amount of energy then light should fucking go instantly and have no time limit. So WTF.

Drunk at 6 on Friday deserves some serious props. You have time to take a nap and then go get drunk AGAIN.

If light went instantly, then it would be able to escape a black hole; hence, it would become a "brown hole". Drunk people have their mind unlocked, so they ask the obvious yet unanswered questions. Kudos to you, pipes!

Oh, and I don't know why. I'm not a physicist. Have fun with your "brown hole".

Rephrased in intelligible form:

Why the fuck would going faster than the speed of light have to take an infinite amount of energy?

In the light photon's own frame of reference it has no time and is everywhere instantly. From your frame of reference it's going really fast, but does have a measurable--albeit estimated--velocity.

Also, in the year 2^1E80 we'll be unable to record the date because that exceeds the number of particles in the known universe necessary to write the date.

It doesn't take an infinate amount of energy it just takes a hell of a lot.

The faster you go the more you weigh and the more you weigh the more energy needed to make you go faster. If you want to go the speed of light which is really damn fast you need a really big amount of energy and a very little starting weight. Sadly whatever your using to create energy will add weight so your basicly chasing your own tail. Untill a weightless source of energy is created we'll never travel at lightspeed and even then we'll crash into things before we see them.

@ SwampGas, couldn't we just record it March 1st 2^1E80 ?

Looks like somebody needs to use threaded mode for awhile.

it wouldn't matter, since all protons by that time will have decayed anyway.

(no pun intended)

In the special relativistic limit (i.e. weak gravitational fields), spacetime has a hyperbolic geometry, so it has asymptotic behavior as you approach the "special" speed that connects the two, the speed of light. For a massive object to reach for the speed of light is somewhat like attempting to reach x=0 while traversing a hill with height y=1/x. Massless objects, however, like photons of light, are not so constrained and are in fact restricted to the speed of light.

As for why spacetime has a hyperbolic geometry, I'm not sure anyone could tell you. It just does.
