Near speed of light travel

[843]

I remember someone telling me in my e=mc^2 thread that near speed of light travel is strictly impossible since our masses would have disintegrated first. Guess again...

Totally doesn't mean einstein was wrong though. He's still right.

[maniac]

Well, I don't really understand physics and things like that, but it looks pretty cool!

[Uncle Xyzzy]

This could be quite nice; assuming it's possible.

Giving new life to a theory that we're on our way to a civil war, followed by a world war. When did that guy say that would happen, anyway?

[Asthaloth]

Totally doesn't mean einstein was wrong though. He's still right.

Umm. No. He was wrong.
SOL isn't fixed.
Mass, not fixed.
heck, he spent the rest of his life trying to disprove his own theory because it disproved G-D as he is represented in the bible.

None the less, Near light speeds is old news.
We can do FTL.
Much faster than light actually.
Just a shame we need somthing akin to a Dyson sphere to power the buger.

(Oh, and somthing that I like mentioning, curent theory says that the universe as we know it as a 5-D black hole.)

I've been reading about stuff like this in my physics book. Very interesting stuff... the only question i've had is

Why CANT we possibly travle at the speed on light.

Consider a black hole. It sucks items in at a speed faster than the speed of light, doesn't it. So couldn't mankind theortically create a minature black hole, use it to accelerate a ship past the speed of light, and then find a way to collaspe the black hole before the ship reaches the center and is destroyed? Or is my logic flawed in some way here?

[SpiraLethe]

It's been a while since I've taken physics, but I don't think that a blackhole technically sucks things in at a rate faster than the speed of light. It's just so dense, that even light cannot escape its gravity (ie: you'd have to be faster than light to get away from that thing). But it does distort space in peculiar ways, so maybe it can be used in space travel.

I've been reading about black holes and shwartzchild wormholes and exotic matter and stuff..

Anyway, I dont want to say wether that could be used or not, I dont really know, but this is a direct quote from a scientific paper regarding how Whiteholes can reversse time and you could theoretically leave it (a sort of parabolic black hole) in the past.

- the spatial geometry at a given `time' depends on what you decide to label as time, how you slice spacetime into hypersurfaces

Hooray for physics. I could go up to you and define a shwartzchild wormhole and you couldn't stop laughing. I guarentee.

Does that mean the universe is continually collapsing upon itself? i've heard that idea before. never heard ot called as a 5d black hole though...interesting...

The news story said...

New antigravity solution will enable space travel near speed of light by the end of this century, he predicts.

Not going to happen. same predictions were made about flying cars, and as far as i know, not a single one is in sight yet. The closest to flying we have is a magnetic powered subway train, but that really isn't flying, no is it?

In five dimensions yes. But we exist in four so no.
In other words; I forget the whole story but I'll grab ma copy of new scientist in the morn.

As for E=MC^2

Energy equals mass X The speed of light squared (which I assume you know)
Well, as you speed up, your mass increases, and so, the energy required to go faster does too.
Of course a Ramjet engine (using volatiles to increase your speed at a slow but sure rate) or antimatter (big BIIIGGGG explosions) could get us obscenely close, just never quite too SOL.

However, interdimensional shenanigans make that unimportant anyway.

How does your mass increase by going faster?

[Asthaloth]

Berr, I wont even pretend to understand why it works, just that I know that it does.

[Shoyru_Lover]

Ahh now black holes is definitely a subject worthy of attention. The space fabric of time and space *goes into fits*

The faster something moves, the more effort or force it takes to move it in relevence to the gravity around it and the resistence something faces in front of it...or not. i'm just assuming here, and you know what that does. ha.

light speed is easy

(well, according to CNN)
