Gamma Ray Bursts ( "GRBs" ) Mean Black Holes?

Ah, thanks for clearing that up, interesting!

Tachyons - i came across an intersting theory about what a significant amoutn of tachyon mass could do when striking a soli object with real mass.
Now bear in mind this ib based upon my early (albeit limited) knowledge of complex mathematics, so i coudl be way off the mark here...
Now, if a tachyon with complex mass hits a solid object, the tachyon would, in theory, impact against the object and transfer some energy across, yes?
Now, the tachyon cannot slow down under c, but it has to transfer SOME energy across to the other object
Following the rules of General Relativity, anything travelling faster than light has time running backwards relative to a stationary observer (rule aout that it has been proven that nothing is ever truly stationary), and this can be linked to the complex mass
now, in theory, upon the impact of the tachyon, the target object gains a complex amount of energy. What i have come to conclude, is that the tachyon particle cause some, or all, of the targets mass not only to by moved in space, but in time also.
Im not talking about a serious level of time travel here, maybe just a few microseconds, either forward or backward, im guessing forward.
What do you think?

That's an interesting idea. However, would a particle with complex mass interact at all with a "real" particle? Plus, remember that the tachyon still has real energy, you won't get your complex energy from there.

If it was moving "back" in time, how do you hit something?

I would think that time would stop, or slow way way down, it wouldn't go backwards. That would just mess everything up. Time travel and me do not get along all of the time. Sure, if you did it, it would be fun. But you couldn't change anything, cause it already happened if you went back and changed it, right :-p

Example, build a time machine now for the sole purpose of going back and stopping WWII. You go back in time, and somehow stop it. K, now all of the time after WWII has shifted (since it never happened.) Your parents may or may not have you as a child, in that case, either way, you may grow up and have no ambition to build a time machine to go back in time to stop WWII. So, that means that you couldn't have gone back in the first place, which means my head is about to go nite nite now...

Way back @ Arcon Nonsense. The flying monkeys killed the dinosaurs. Lol ill edit this to have more meaning when i finish reading.

*scratches head* arg im only in geometry! So let me get this straight:

1. Black holes are from very big stars(usually). (everyone knows that i think)
2. The event horizon is just before the singularity.
3. After any bit of matter emits its fair share of radiation it also gets sucked through the event horizon and into the singularity.
4. The singularity its comprised of all matter ever sucked into that specific black hole.
5. The singularity defys all laws of the space - time continuum, having an infinite density and having immense gravitational pull.

So, on 5, my mind is having trouble accepting the fact that "infinite" density. Is that meaning that it is always growing without end?

Correct me on all that if wrong. I find this interesting.

Also, are a joule and an erg related in any way? How many joules = 1 erg or vice versa.

To claryfy a hyper nova is when a star is born and grows so fast and large its mass falls in on itself causing a huge blast. Now unlike a regular explosion the energy is compressed into two streamers eminating from the centre. This causes the vast majoraty of GRB's.

1. Black holes are from very big stars(usually). (everyone knows that i think)

Yes. 99% of black holes are from big stars, and the other 1% are so far only theoretical.

2. The event horizon is just before the singularity.

Not necessarily. Depending on the mass of the black hole, the event horizon could be quite big.

3. After any bit of matter emits its fair share of radiation it also gets sucked through the event horizon and into the singularity.

The reason matter emits radiation is because it gets hot as it spirals round, before going in. That's the cause of the accretion disk.

4. The singularity its comprised of all matter ever sucked into that specific black hole.

Yes.

5. The singularity defys all laws of the space - time continuum, having an infinite density and having immense gravitational pull.

The term "singularity" doesn't actually specifically mean the thing at the centre of a black hole, though. It refers to a point where equations break down. 1/x has a singularity at x = 0. So, because all this matter has been compressed down to infinitesimal size, our conventional laws of physics cease to apply.

And why the big grin?

Arc was grinning becasue he said something about if that was how dinosaurs got extinct, then I said

Way back @ Arcon : Nonsense. The flying monkeys killed the dinosaurs.

ok, black holes are anomalys caused by he collapse of a star witha huge mass. nothing can escape a black hole but a nonexistent particle called a tachyon which in truth has brokes a fundametle law of physics, nothing can excede the speed of light. The event horison of a black hole is the edge of it's gravatational pull, thus being the "edge" of a black hole. now no matter can ever enter a blck hole due to it pulling matter aprt and it causing time dialation.The theroy of a white hole is probably caused by the fact that for the moment that the black hole explodes unfathomable amonts of energy are released, forming the opposite of a black hole.now if x is the gravatational pull and y is the speed required to escape a black hole, a tachyons speed must be at least y.

(sorry but my thoughs are jumbled right now)

a tachyon doesn't defy physics. It changes the E=MC^2. We think of all things having mass, however, if you have mass you CANNOT EXCEED THE SPEED OF LIGHT. Therefore, how much would a tachyon weigh???

Thats right, negative mass....

Mon Nov 08, 2004 7:22 am by kimk

if you have negative mass, then you inevitably have negative energy. which would pretty much mean that it (tachyon particle) will absorb energy? so if it hits a body, it will absorb energy from that body?

now we know matter is some insanely dense form of energy. so does tachyon ... 'leech' the energy from the body? hence effectively disintegrating it? is that how tachyon weaps work ? so if you slam enough negative energy into a body, you have it vaporising?

what happened to the conservation of energy of the universe?

Mon Nov 08, 2004 12:16 pm by Megistos

Tachyons fit very nicely into E=mc². When you have a negative squared mass, you expect things to work out differently. Tachyons

Mon Nov 08, 2004 1:34 pm by Indy11

So...... Tachyons indicate that FTL is possible? That at its slowest, a tachyon travels "merely" at light speed?

I wonder what tachyons are in a dimension other than our known four

Mon Nov 08, 2004 11:23 pm by Sirius

Technically they do have mass. Even if it is negative. Therefore it does exist in at least 3 demensions. But, if it is traveling faster than the speed of light... Would it exist in time?

One last Q. The accretion disk (sp) is all the matter swirling around the event horizon before getting added to the rest of the matter in or near the singularity?
