If you were moving at the speed of light, you would not move at all. This is due to time dilation that happens as you move closer to c, or 3 * 10^8 m/s.

The warping of time isn't normally noticed by us, as we only travel at very small fractions of c. But if you travelled at a significant speed, say 2.7 * 10^8 m/s, you would find that everyone else outside of you would be moving slower, at least relative to you. Those outside would be perfectly justified in saying that you were moving slower than they were, too.

So, as your speed approaches c, your motion through time would get slower, until at c it froze.

I always used to wonder how exactly the Shaw-Fujikawa slipspace drive worked in Halo because of this. I think it's something involving D-branes and higher dimensional space... I remember seeing a reference to a paper written by Shaw and Fujikawa about this in one of the Halo books, or somewhere else...

I just read all 3 pages... Im going into 8th grade and surprising I actually understood almost all of the basic ideas mentioned here! Ok... Had to say that.

Ok here is the deal... The drive in the halo books doesn't have to have a way to work becuase.... well it's in a BOOK. Its not real there is no way to justify how it works because we don't even know if something like that is possible.

I want to know if one is traveling at Speed X in one direction (in relation to the surface of Terra) and fires a projetile in the exact opposite direction at speed X, will, to one stanting still in relation to the surface of Terra, will the projectil appear to simply fall to the ground?

(I hope my wording is clear and exact enough, for you at least to understand what I am asking.)

Technically it should... but i'm not sure.

bah

Well GJJ, I said you cannot accelerate up to the speed of light. As for moving your arm, at that speed, any movement you make would throw off the time dialation such that your moved part would either go much faster than your, or much slower than your body's average time. Either way, the result is most likely instantaneous death.

As for time dialation, as you move faster, your time slows down. The result is that everyone else would seem to be moving faster, not slower. Since your time is slower, and you cannot exceed the speed of light, distances begin to appear to be shorter. It gets really weird when you go that fast. The whole universe changes for you at those speeds. Also, since your time is slower, and yet you must have the same mass for yourself, anyone looking at you would see you as being more massive. This means that as you approach the speed of light, more and more energy is required to accelerate you since you are more massive. So much more that there just simply isn't enough to get you up to the speed of light.

nothing unless you were going faster than the speed of light than it would just light up the back of teh bulb in your headlights, but how would you get your car goign the speed of light anyway.

I want this thread to come back, so how about another brain teaser?

These are nowhere near as advanced as before - these are just thought provoking. You won't need any degrees to solve tham (although they may help on some).


The fair had arrived in town. "A prize for guessing the number of balls under the mugs," shouted one stall owner, as he placed four upturned mugs on the counter in front of him. Each concealed the same number of balls and on each mug was a statement about the number of balls underneath : One or four; Two or four; Two or three; One or two. Only one of the statements was correct. How many balls were under a mug and which statement is true?

That ones easy, so I'll give you another one.

Olbers' Paradox

Why isn't the night sky as uniformly bright as the surface of the Sun? If the Universe has infinitely many stars, then it should be. After all, if you move the Sun twice as far away from us, we will intercept one quarter as many photons, but the Sun will subtend one quarter of the angular area. So the areal intensity remains constant. With infinitely many stars, every angular element of the sky should have a star, and the entire heavens should be as bright as the sun. We should have the impression that we live in the center of a hollow black body whose temperature is about 6000 degrees Celsius.

Just -- no...
Besides - that has been discussed -- new pages son...

As for the energy and anti-energy thing. Someone said earlier that if matter and anti-matter touch they annihilate each other. Somone also said that energy and matter are the same thing. If you guys didn't see the connection then I will explain it to you. If matter is the same as energy then anti-matter would be the same as anti-energy and if energy and anti-energy touched they would also annihlate each other there would be no wierd inter-dimensional effects there would be nothing.

Energy is Matter - but not all matter is Energy. Like Ketchup is a condiment, but not all condiments are ketchup. So AntiMatter is a physical negative, and Anti Energy would be a Force Negative.

Now did anyone give any thought to Olbers Paradox?
