[QUOTE=rosthouse;21657213]Oh right, it's getting late here :v: And I just checked it again, it still is the Hawking radiation :wink:
(To be correct, the particles are not created by the Hawking radiation, the surviving particle is the actual radiation)[/QUOTE]
Ha, thought- it would be p. dire shit if hawking radiation from an antimatter blackhole happened to wander upon our quaint little planet
Course, the chances are impossibly low but it'd be an interesting way for the world to "end"

Riight, my bad. It's late too :v:
Is there any "preference", as to which one escapes and which one falls into the black hole? Or is it a random kind of thing? I need to buy Hawking's book.

Well, it depends on whether the black hole is made of matter or antimatter as to which goes in and which escapes, I think.

I'm not even sure if you can say one particle is matter and the other antimatter. They are just virtual particles, they can not be detected by our current sensors (we should be able to detect matter and antimatter). We can mesure the effects over indirect methods though.
[quote=Wikipedia]The virtual particle forms of massless particles such as photons, do have mass (which may be either positive or negative mass)[/quote]
Haha, wow.
Apparently, though, if they're observed they behave like normal photons?
So... Couldn't virtual photons be the answer to exotic matter, then?
All these science threads are really improving the overall quality of general discussion.
I applaud you OP for making this.

You should applaud to Eudoxia, as he's the guy who started all this, I'm just a copycat :wink:
But it's true, GD seems to be getting better.

You're giving me too much credit, I simply shared what others did. They should get more credit for the thousands of man hours of work that went into those projects.
Don't kill the messenger, but don't give him all the moneys either.
is it acceptable to shower the messenger in dicks

That's true, all those people working on this and contributing, it's such a huge effort. But it also takes effort to read it and put it into something the average person can understand.
One :neckbeard: to all those scientist all around the world, who are doing all this awesome work :buddy:

Oh yes please.
[QUOTE=aVoN;21645411]The OP is quite mixing too much science together, which are not connected.
E = mc^2 has nothing to do with FTL. It is a result of the Legendre transformation of the relativistic Lagrandian (which gives the energy).
E = mc^2 is only valid for particles [B]at rest[/B].
It also does not "forbid" FTL. Special relativity does, except you have an imaginary mass. And the correct formula is E = mc^2/sqrt(1 - (v/c)^2). Only this one shows, FTL for real mass gives imaginary Energy. But energy has to be real, so you need imagninary mass cause i^2 = -1 makes the Energy again real.
And bending spacetime is a consequence of general relativity which allows pseudo-FTL travel, yes (like with the Alcubiere-Drive you have posted a few pictures about).[/QUOTE]
Bitch got told.
Also, 'bent'.
Yes, Lets BEND the UNIVERSE! Maybe we should make...Space Origami!
[QUOTE=BAZ;21656807]mr = m0 /sqrt(1 - v^2/c^2)
Calculating mass increase with velocity. The problem, is that if you reach the speed of light you divide by zero, which causes an infinite mass (Which are pretty hard to move!)[/QUOTE]
"Relativistic Mass Increase" does not exist. You can't associate the 1/sqrt(1 - (v/c)^2) term to the mass, because it would violate newtons law of force = time direvative of momentum.
Only the energy increases as faster you are.

the final frontier

its continuing mission: to explore strange new worlds
to seek out new life and new civilizations

That's, in german, threaded writing ("Schnürchenschrift"). Ok, it is quite exagerated here.

It's a type of writing that was invented to help learning to write, as it is easier to do. There's only a german article on wikipedia: [url]http://de.wikipedia.org/wiki/Schulausgangsschrift[/url]

In order to create the effect, we’d need negative energy[/QUOTE]
[QUOTE=rosthouse;21644767]negative energy has yet to be proven/found.[/QUOTE]
case closed
Is it possible for something to have negative mass? Couldn't that go FTL?
Great detailed information, I will visit you often.
Here is some interesting things.
