I know matter, What is anti matter? Has something to do with black holes......right?

right now, ant-matter is nothing more than a theory....<br /><br />Was a constant put in place originally by Einstein to deal with the recurring issue of the seemingly paradoxal problem of missing mass in the universe.

One question...<br />Do you have any dark matter to show me? Has it been put in a capsule or even directly observed? What working model uses dark matter without having to postulate other exotic materials that are un proveable?<br /><br />Even, When Einstein put this "matter"in his work on the grand unified theory it still failed to predict the seemingly ackward rate of expansion observed in the universe. Ant-quarks, gluons, etc... deal souly with quantum mechanics. Totally different science....<br />

When the experiments receive the subsequent batch of antiparticles, the beam will contain recycled antiprotons – assuming scientists manage to keep the antiprotons "alive" inside the Recycler for a long enough time.<br /><br />"As of now, we've achieved a lifetime of greater than forty hours," said Shekhar Mishra, who heads the Main Injector Department and Recycler Commissioning. "And plans are already in place to improve the lifetime by at least a factor of three." <p><hr /></p></p></blockquote><br /><br />It sounds real to me.<br /> <div class="Discussion_UserSignature"> </div>

You know what I'm an Idiot, it was early and I didn't read the title well. I was talking about darkmatter. Sorry, I wholehartedly concede to the point given.<br />

We do indeed have anti-matter that we have put in a capsule and directly observed, although only for very short times in microscopic quanties. Dark matter though is a different issue. It wouldn't be dark, by definition, if he could show it to you.

maddad - on dark matter.<br /><br />You seem to consider all dark matter to be exotic or unknown.<br /><br />This is not the case. Every time an astronomer discovers an extrasolar planet, they have found what was formerly dark, or unobserved, matter.<br /><br />Any matter that is not yet observed is dark matter.<br /><br />I assume you meant exotic dark matter, or forms of matter which have not yet been proven to exist.

matcat- I know Milky Way was observed to have a jet of antimatter which may have something to do with black holes. <br /><br />I will research it and get back to you.<br /><br />Meanwhile, there is also the question as to why, in the origin of our universe, matter predominates over antimatter - at least in our observable section.

matcat - Here is a brief quote on that anti-matter jet in Miky Way proven by the specific gamma ray spectum caused by matter to antimatter collisions (see more detailed papers on the actual gamma ray observations and specific wavelengths) -<br /><br />Plume of Antimatter Discovered<br /><br />"Astrophysicists recently discovered what appears to be a 3,500-light-year-long plume of antimatter streaming out of the core of our galaxy, the Milky Way, reports The New York Times. Antimatter consists of atomic particles that are exactly like normal matter except that they have opposite electrical charges. Contact with particles of ordinary matter results in mutual annihilation and releases powerful gamma rays having a specific energy. Scientists identified the plume as antimatter by tuning the Compton Gamma Ray Observatory satellite to that energy level. As for the effect of the plume, "the astrophysicists said it did not threaten Earth, just their image of the galaxy."" - "Awake!," 10/22/97, p. 29<br /><br />If I remember correctly, subsequent research linked this jet to black holes, or a supermassive black hole, near the galactic core.<br />

Steve - you seem to have the same mental block as maddad- assuming dark matter is some exotic, unknown form of matter.<br /><br />Reputable Science Encyclopedias show otherwise. For example:<br /><br />Here is a quote concerning dark matter, which notes evidence for dark matter in Milky Way and also highlights known forms of matter:<br /><br />"Stars closer to the galactic center have shorter orbital periods than those which are farther away, but they do not behave like planets around the Sun. The mass of the galaxy is spread out over a vast volume and the speed of a star is determined not only by its distance, but also by the mass which lies between it and the center. The greater the distance of the star the greater the mass acting upon it.<br /> Close to the galactic center, velocities are quite high. They decrease towards the outer fringe of the nucleus, and then farther out they increase to about 230km per second at the Sun's distance, and to some 300km per second at a radius of 60,000 light years.<br /><br />The Galactic Corona<br />The high speeds of stars in the outermost parts of the galactic disk imply that a large fraction of the Galaxy's mass lies in the fringes of the system. If this were not so, the speeds of stars would begin to decrease at distances beyond that of the Sun. One RR Lyrae star, nine globular clusters, 3 dwarf elliptical galaxies, and the two Magellanic Clouds are known to lie at distances between 65,000 and 200,000 light years from the galactic center. If, as appears to be the case, they are all part of the halo, then it is possible to calculate from their speeds how massive the galaxy must be in order to prevent these objects from escaping into intergalactic space. This mass turns out to be between 1,000 billion and 2,000 billion solar masses.<br /> This mass consists of neither luminous stars nor neutral hydrogen, or it would be visible. Possibly it consists of cool planet-sized lumps of matter, old dead stars, or very low-mass st

maddad- Does this mean we agree?<br /><br />The point is that we can now show people what was dark matter.<br /><br />Of course, once shown it is no longer dark matter!<br />As in the case of newly observed, aka discovered, extrasolar planets.

bobvanx- Thank you.<br /><br />I am one of Jehovah's Witnesses.<br /><br />Trying to be objective, not merely subjective, I honestly believe Awake is a good source for accurate information - that comes from decades of research using many sources.<br /><br />On the antimatter plume, I have found it quite interesting that most sources have become strangely silent on this discovery during the last 5 years.<br /><br />On the old SDC I had a thread on this and asked whether this plume was confirmed by further research.<br /><br />The responses were good, as were the links. Plently of evidence from many sources around 1997 and just before.<br /><br />You will find it becomes called an annihilation plume or jet a little later.<br /><br />And it may involve a supermassive black hole near the core of our galaxy.<br /><br />I am interested in more recent evidence and observations and links, etc.<br /><br />Thank you again.

Paul, we have discussed several times your religious views. If you do you want to open that discussion again then keep your religion out of science threads.
