[QUOTE=acds;39141482]Quite sure you're completely correct. Not saying it would be feasible for us (well not in the near future anyway) to dump that much antimatter into a black hole, just wondering what would happen. Though there is the theory that a dense enough energy concentration could create a black hole, so maybe not much would change.[/QUOTE] Nothing out of the ordinary would happen. Matter-antimatter pairs don't annihilate into nothing despite what the word "annihilate" suggests. They become energy (i.e. a photon) which still contributes to the stress-energy tensor just like matter would. A positron falling into a black hole acts the same as an electron falling into a black hole. Furthermore, once matter falls past an event horizon it's irrelevant what kind of matter it was or how it fell in or whatever. Black holes only have mass, charge, and angular momentum. The distribution of matter inside is completely unknown to an outside observer and irrelevant to the properties of the black hole.
[QUOTE=Falubii;39149210]It's 11 billion lightyears away. [del]It's been red shifted into radio waves. It even says in the article it was detected using radio telescopes.[/del] Edit: That part was wrong. They only used the radio telescopes to locate where the gamma ray burst originated in the galaxy. I don't know why I thought gamma rays could be red shifted down to radio waves. It still isn't dangerous though. At 11 billion lightyears it can't do anything.[/QUOTE] Hence the title of this thread is misleading as if it's meant to scare people and instill fear mongering. The title of this thread should be really called the article's original title which is "Galaxy's Gamma-Ray Flares Erupted Far from Its Black Hole" which the fear mongering effect would be lessened.
Why didn't they release this news data in November 2011, when it happened? Fear of World's End and mass suicide? Who knows...
[QUOTE=JohnnyMo1;39138209]Antimatter grows a black hole in the exact same way matter does. Yes, negative energy will shrink a black hole. Now as for how we could use that fact to actually shrink a black hole out of existence manually, I dunno.[/QUOTE] use the huge relativistic jets it spews out to launch it far, far away
[QUOTE=irukandji;39153413]Why didn't they release this news data in November 2011, when it happened? Fear of World's End and mass suicide? Who knows...[/QUOTE] Probably because they had to get the data right.
[QUOTE=Eudoxia;39136380]This is why we should live underwater people. It's the perfect radiation shield.[/QUOTE] [img_thumb]http://hdwallpapersbase.com/wp-content/uploads/2012/10/Bioshock-Rapture-Wallpaper.jpg[/img_thumb] I like your thinking
Fucking shit, was the burst really weak or was it just radiation and had no chance of vaporizing the planet.

All this matter and anti-matter stuff confuses me, if anti-matter destroys matter(turning it into energy), doesnt that break that rule thing of the universe that matter cannot be created or destroyed? Or was it energy?

Or was it energy?[/QUOTE] Energy. Antimatter and matter just convert into energy (as far as we know, possibly other things we can't detect as of now but that's pure speculation on my part).
"Well? Huh? Is it me?" "No, no... no, I've just had too much gamma lately... it's not you, it's me."
[QUOTE=Jacob_sword;39156250]Fucking shit, was the burst really weak or was it just radiation and had no chance of vaporizing the planet.[/QUOTE] Radiation can still damage the planet (i.e. the stuff on the planet, the planet doesn't care), but yes, the burst was weak.
[QUOTE=acds;39158449]Energy. Antimatter and matter just convert into energy (as far as we know, possibly other things we can't detect as of now but that's pure speculation on my part).[/QUOTE] Ah, that explains it.... Bring on the boxes
