Is the matter in a black hole at edge or center?

OK, I'll take the S&T out of the plastic envelope, but if that's what they said, they seem to be wrong.<br /><br />The 511 kEV signature is that of matter-antimatter <br />annhialation. <br /><br /><This line is a witty joke /><br />After all, it's what the Enterprise runs on <img src="/images/icons/smile.gif" /><br /><end witty joke /><br /><br />However, let me see what they have to say.<br />Maybe there's a new justification for that opinion. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Such a huge dark matter plume one cannot see.I rule out it not dark matter.It may be anti matter.At such long distance no fear.

<i><br />OK, I'll take the S&T out of the plastic envelope, but if that's what they said, they seem to be wrong. <br /><br />The 511 kEV signature is that of matter-antimatter <br />annhialation</i><br /><br />Yes, that's what I said previously. On p.44 4th paragraph down they ask Where does all this stuff come from? Then in the 5th paragraph ...if annihilating dark matter particles produce the positrons.<br /><br />My concern is semantics, antimatter plume doesn't mean antimatter. I believe the plume is the annihilation<br />of matter and antimatter, or the 511-keV gamma rays that we are concerned with. <div class="Discussion_UserSignature"> <p><font size="4"><strong></strong></font></p> </div>

From:<br />http://www.seds.org/spaceviews/9705/news.html<br /><br />Scientists Discover Antimatter Clouds in Our Galaxy<br /><br />Scientists have found evidence of two large clouds of antimatter located in the Milky Way Galaxy which may be linked to a large black hole in the center of our galaxy or supernova explosions of massive stars.<br /> Scientists from Northwestern University, the Naval Research Laboratory (NRL), and other institutions used an instrument on the Compton Gamma Ray Observatory to find two clouds of antimatter. One large cloud was found in a region surrounding the center of the galaxy, while a second plume of antimatter extended up to 3,000 light-years above the Milky Way's core.<br /> The second plume of antimatter was unexpected and has yet to be explained. "The origin of this new and unexpected source of antimatter is a mystery," said Northwestern University physics professor William Purcell.<br /> James R. Kurfess of NRL outlines three possible sources for the antimatter plume. "The antimatter cloud could have been formed by multiple star bursts occurring in the central region of the galaxy, jets of material from a black hole near the galactic center, the merger of two neutron stars, or it could have been produced by an entirely different source," he said.<br /> The astronomers used the Oriented Scintillation Spectrometer Experiment (OSSE), one of the instruments on the orbiting gamma-ray observatory. The instrument detects gamma rays produced when positrons, the antimatter version of electrons, come into contact with regular matter and annihilate.<br /> "It's possible that this mapping effort could turn up evidence for other unexpected clouds of positrons," Kurfess said. "We will keep monitoring the center of the Galaxy in the hope of seeing evidence for a black hole 'turning on' and producing positrons," he added.

If it is antimatter ,wemay wait and see if we get positron,Mtter+antimatter =gamma ray +positron.

<i> <br />The instrument detects gamma rays produced when positrons, the antimatter version of electrons, come into contact with regular matter and annihilate. </i><br /><br />Here, they say that the instrument is detecting gamma rays, not clouds of positrons, which would indicate a cloud or plume of antimatter.<br /><i><br />"It's possible that this mapping effort could turn up evidence for other unexpected clouds of positrons," </i><br /><br />Now, they're implying that the previous statement was a cloud of positrons, which would be antimatter. So which is it? Gamma Rays, or a cloud of positrons? I have to admit, that I'm a little confused. <br /><br />Well, I'm not confused anymore, I clicked on "Evidence" from the article and found "....which scientists call antimatter annihilation radiation" Which answers my question, it's GAMMA RAYS. Semantics, sheeeesh! <div class="Discussion_UserSignature"> <p><font size="4"><strong></strong></font></p> </div>

<i><br />If it is antimatter ,wemay wait and see if we get positron,Mtter+antimatter =gamma ray +positron.</i><br /><br />I agree with you 100% Alokmohan. That formula simplify's my understanding of this confusing situation. THANKS! <div class="Discussion_UserSignature"> <p><font size="4"><strong></strong></font></p> </div>

We require more information.

kyle_baron, you all - the antimatter-matter annihilation produces the specific type of gamma rays being observed. I.e., the gamma ray signature proves antimatter annihilation is the cause - therefore antimatter's presence is proven.

alokmohan - It is:<br /><br />positron + electron = gamma rays

SEARCH - Thank you once again for your research.<br /><br />Its good to know the plume has not been totally ignored in the scientific literature!<br /><br />Extremely busy today, but I will research your link soon and respond better later.
