NASA discovery, speculation inside - Page 6

Pharazon · 05-12-2008, 01:20 PM

Note that Gamma Ray bursts only occur at the creation of a black hole. And as far as I'm aware that's still speculation in and of itself? They only occur in very, very deep space, making it impossible for us to know what exactly is causing them for now. That the creation of a black hole emits them is just the leading theory.

Quote:

When black holes attract matter, they don't swallow everything. In the process of accelerating material to nearly the speed of light, the black hole spits some of the incoming stuff out in two opposite directions along its axis of rotation.

ugh, suck it

Hawking Radiation. Look it up.

Hawking Radiation has nothing to do with the jets in an accretion disk, by the way. As far as I know, it's not even confirmed definitively yet.

so is today the day we find out that they built a ladder to heaven?

Well, a "gamma ray burst" does occur at formation as the star collapses upon itself, some of the matter rebounds, goes super nova, and the rest collapses into a black hole (sometimes) and ejects a planetary nebula and all sorts of radiation.

But the mysterious gamma ray bursts, known by that term, eject orders of magnitude more energy, something in the millions or billions of what a super novae does. Sort of neat, they can literally sterilize portions of galaxies many lightyears away.

Hawking radiation is a quantum function where two virtual particles appear at Schwartzchilde radius except one is just inside the limit, one is outside. Instead of annihilating, one escapes and the other is sucked into the black hole. At least I think that's how it work.

But I'm no physics dude, only interested it and took some GSCI electives.

edit: but this discovery has nothing to do with a black hole probably, since it specifically says in our galaxy, has been sought after for 50 years. We already know about our super massive black hole because of the insane orbits of stars at galactic center. Well, maybe they caught the blackhole eating a star in a not so stable orbit. But that doesn't fit the bill either.

My guess is evidence of superstrings still!

Wait wait.... they found fucking Jimmy Hoffa!

Yeah, but it specifically says Chandra found it, and that's an X-ray observatory. It seems like your astrophysics knowledge is better than mine, but as far as I'm aware the only things cranking out X-rays in our galaxy tend to be blackholes or various other similar objects like I mentioned before. I'm virtually positive Chandra's pretty useless at finding planets, for example.

I have no idea if it could validate anything about superstrings, but I wouldn't think so. And have superstrings even been theorized for 50 years?

My best guess is the ole supermassive black hole in the center of the galaxy thing. Aliens would be way more fun though.

Possibly this?
