Alcubierre FTL Drive

Alcubierre drive

Discuss until I get back.

I have heard about this concept and if this happens well everything is f*cked. Why? Because if you can bend space in such a fashion well nothing matters and you can't hit a single target because they can bend space and time(the two are connected) to move anywhere. That and you can use it to move a black hole everywhere, and fold the universe in on itself.

Shouldn't this go in Offtopic?

As far as I know FTL drives operate on the Rule of Cool, let's just leave it at that instead of having theoretical physics discussions

As far as I´ve read it, that Alcubierre FTL Drive basically is a Star Trek style warp drive needing massive ammounts of energy.
Also, Keon, you´re right there was a discussion about this in the off-topic area.
Here´s a link.

A warp bubble traveling at 10 times light-speed must have a wall thickness of no more than 10−32 meters. This is close to the limiting Planck length, 1.6 x 10−35 metres. A bubble macroscopically large enough to enclose a ship 200 meters across would require a total amount of exotic matter equal to 10 billion times the mass of the observable universe.

That seems reasonable..

Read about something similar a little more than a year ago. It might be possible with the right technology.

There are an awful lot of things that fall into that category.

Take a football- (American) shaped vehicle and surround it with a large ring (oriented vertically) made of exotic matter of some sort.

Say the ring is in the shape of a thin, wide, well... ring. In this case, it would require a massive amount of energy (Quasar power generator, anyone?)



OR take a very massive torus- (donut) shaped ring. This would require much less energy to power (an amount of energy comparable to the mass-energy of the Voyager spacecraft per second of operation.) Unfortunately, it would be very difficult to build a torus that large out of exotic matter (probably strange quarks or neutrinos):

A vulcan ship.

Divide by zero error. Two still does not equal three.

It is possible to devide by zero, but you must be careful not to create any paradoxes
(ook at the "early attempts"-section of this Wikipedia article)

No. It is not; you are wrong. Dividing by zero is impossible and the answer is undefined. Anyone who says otherwise doesn't have a complete grasp of modern mathematics.

You'll learn lots of ways of getting useful information in divide-by-zero scenarios once you start taking calculus.

I'm sure that's true, but that doesn't make it a legitimate operation. Out of every maths classroom I've ever walked into, I can only remember two that didn't have some variation on 'Dividing by Zero is a Sin!' written somewhere on the wall.

Mostly you end up doing math on equations and expressions. If it becomes undefined at a point or a range, you declare the range in which it is undefined and call it a day. Doesn't invalidate the other points in the equation.

Doing. Fixed.

Excellent.

I'm glad we had this talk.

I am too.

I like pretzels, but goldfish are much better.

Ladies and Gentlemen!
Mares and Gentlecolts! (for da bronies)

I present to you the daily non-understandable-Fr0stbyte-special-technical-scientific-talk!

But that wasn't meant to be...nevermind.

Excuse me while I go cry in the corner.

Well an alcubierre drive is just exotic matter in a rugby ball (or football shape for you americans) surrounded by a doughnut of exotic matter, but it can only bend space at a certain radius, contracting the space in front and expanding the space behind, apparently NASA have done the maths and they say its entirely possible, they just have to work out what exotic matter is.

You could technically fold the universe in on itself, but you would need a hell of a lot of exotic matter, and seeing how hard it is to get anti-matter, I don't think thats going to happen.

And warp drives are the only way that our ships could possibly reach everyone elses systems within the time span that we want, and you can hit a ship which is going at warp speed, imagine what an impact a single atom of hydrogen would make on a ship travelling faster than light... so you would have to solve that problem.

Idea:

If you take a Antigravity electronic device you can use gravity to fold space instead of exoyic matter.
