speed of light

[Hagbard]

the faster you move in space , the slower you move in time . If you traveled with the speed of light , there would be a time standstill for you .

[You_Are_A_Super_Player]

Very close to it and beyond it, hypothetically.

FTL speeds are hard to wrap your mind around. I mean, at that point it takes more energy to slow down, meaning the less energy you put in the faster and faster you will go.

deep shit yo.

Well, it depends on how you accomplish it. Warping space time technically allows FTL travel in that if your craft inside the warp bubble will arrive at it's destination before a beam of light traveling outside the warp bubble. However in actuality you aren't moving at all.

The something something drive, yea. That's another thing I find hard to think about. Sounds like some more '90s bullshit.

Actually it holds up pretty well in theory. Obviously we don't have the technology to do it yet but there's no reason it's impossible. There were actually a few theoretical models for how it might work, along with some other possible methods, presented in a NASA project that was studying new methods of space propulsion that were theoretically possible but would require major breakthroughs in physics first.

SO TECHNICALLY IT'S MORE OF A TIME MACHINE?

[Nikias]

Not really. Think of the warp bubble as a marble and space time as a piece of rubber tubing that the marble is inside of. Now you stretch the part of the tubing behind the marble and compress the part in front, the stretched part (where space-time is being expanded) pushes the marble through the tubing towards the other end, which is closer because it is being contracted. The warp drive gets it's name because it literally warps the fabric of space-time.

well i understand that you would die but if for some reason you were able to go the speed of light and not die would you age.

You wouldnt be able to se where you are going either since you are going the speed of light.

[philipjfry]

186,282 miles per second in theory no you will not age

[cjhoser]

most of you make me want to kill myself.

[gkjand]

3*10^8 m/sec
I don't know how did they came with such an exact figure !
I doubt it is true..

[whitewolfdragon]

the speed of light is roughly about 187,000 miles a second. No you would not age.

[hovla]

You wouldnt be able to se where you are going either since you are going the speed of light.

Thats not true. You will be able to see infront of you. But wont be able to see behind you since light is too slow for you. But light infront of you will still be ''hitting'' your eyes so you could see.

[F0x3d]

Hahahahahahaha...I'm not sure if someone has misunderstood. I have been talking about the living things that can move as fast as the light speed. There is hard evidence? I don't think so. Until now no one can make Captain Kirk's Enterprise a reality. And no animate things can travel to any place at the speed of light. So Einstein's theories are now nothing but sweet dreams on pieces of paper. However, those dreams are good enough for Hollywood producers to make lots of money...hehehe..

You moron. Thats what has been accepted as the theory of relativistic mass. It IS impossible to reach c (3.0x10 ^8 m/s) because inertia would exponentially reach infinity...

What the hell are you trying to prove?? Einstein never said anything about living things moving at the speed of light. He simply proved the relativity of length, mass and time.

[bustyasianchick]

yea idiot

You cannot go the exact speed of light in real spacetime. If you were to go .999999999^ the speed of light, which is completely possible, you would age- but MUCH more slowly. According to the theory of relativity, time is relative in the universe. If you were to get in a spaceship and go 0.99 lightspeed in the same direction for a year, then were to point your ship back to earth and return, you would find that on Earth around 300 years of time has gone by. Time is also dependent on gravitational force, and that is why clocks tick slower in space than they do on earth.

There's a good episode of Stephen Hawking's "Into the Universe" on time travel that covers this well.

[NikkiCarton]

The possibilities of traveling at the speed of light have dazzled us for years. Wondering theory of specific relativity tells us that a person traveling at the speed of light would be frozen in time due to the fact that space and time are intertwined. Einstein used the example that if he was traveling away from a clock in a bus going the speed of light, the clock would appear to be frozen and unchanging because the light would not be able to catch up.

Time dilation is a very interesting subject so i chose to necro this thread.

Technically youd still age at the same rate as any other. One day for a person travelling at the speed of light would still be a day for a person left at the starting point, however the person at the starting point would live through many more days in the same relative timeframe that the traveller does.

[FilterDreaming]

This is why you just say it is impossible. I find hypothesizing about the impossible to be quite nonsensical.

If no one one hypothesized the impossible we wouldn't be able to do half the things we can now.

This is what I was going to say.
