Was wondering if anybody knew what the fastest moving object ever known was? On Earth and in Space. Thanks.

In reality, nothing can move faster than the speed of light, or c. Therefore the fastest moving thing ever observed are photons.
I know in certain partical accelerators that we have propelled atomic particles to very high sublight speeds though, as for other, outer space observations, I have no idea.

(my theory) not nessesarily if you create massive amounts of energy it would basicly peel space away giving less effect to this law and alowing faster than light travel, but this would not be a natural phemonen

Fastest thing in the known universe? Cooking time for a McDonalds hamburger

Massive amount of energy would warp space like a black hole instead of peeling it , basically it energy ( matter is just a concertated form of energy) that responble for gravity. So there no hope for faster than light in that manner. Other than Photons, Neutrinos are the fastest know object, in fact there are theories that suggest Neutrinos may be a form of Tachyonic matter, meaning that they would actually travel faster than photon, but this has not been proven. Next in the order of speed would be cosmic rays, these particles ranging from stripped Helium nucleus to an array of subatomic particles travel almost near the speed of light, at speeds far exceeding what we can produce in current particle accelerator. Then come Quasars, these radio galaxies have speed of up to 90 percent the speed of light and their rapid motion are due to the expansion of space time caused by inflation. Current observation show that this inflation effect is actually speeding up so as the universe ages, these galaxy will go faster and faster, fading into infra red due to the doppler effect. Eventually these galaxies will break the speed of lights since Einstein Laws of Relativity put no limit on speed due to the expansion of space time, at this point these galaxies will no longer be part of our physical universe. If this inflation does not stop, it will in end cause all of matter to rip apart, even atoms will be torn asunder.... This is what astrophysicist call the big rip. |

i thought scientists knew about some mesons, gluons, or leptons that travelled ftl ftl = faster than light  |

There is a theorical sub-atomic particle called TACHYON (yes, it is not only a star trek invention). Is belived that it(if realy exist) travels faster than light. See tachyon in wikipedia |

No all normal matter is limited by speed of light. Cosmic rays are the highest speed particles seen, that even particles created by their collision with atomsphere are travelling close to the speed of light. Muon which have a half life of 2.2 microsec that are created by the cosmic rays smashing into atoms high in the upper lever of the atomsphere are moving so fast that the Warpage of time and space that they experence due to relativitic dilation allow them reach the surface of the earth and be observed in cloud chamber. |

Well it not it has to do with the faster objects in space, and due to cosmic inflation, billion of years in the future galaxies and eventually even the atoms of body will be flying apart at speeds faster than light |

that was what I ment when I said peeling away. Using the blackhole you would be sucked into it but if you had the source of the energy attached to you the black hole would move with you and since there is less space in this area (there infinite threads of space in just an inch so it would be less of infinte but still less) as I said these laws would have less effect thus producing faster than light travel |

what you posted make no sense. normal energy and matter only works against going ftl. Blackholes are black due to the fact that space is so warp that nothing can escape it. The only to warp space in a manner to produce FTL is thru exotic matter, negative pressure or negative energy. All these produce postive curvation or allow you to warp space in a manner that it will expand faster than speed of light. That what happen after the big bang, the universe expanded faster than the speed of light due to Negative pressure created by an energy field ( negative in magnitude) that cause the universe to grow at amazing speed. The visible universe, is just a small part of a larger universe, which scientist believe is really at least 75 billion ly across and not the 13 billion that we can observe. |

hawking says ... on http://www.newscientist.com/article.ns?id=dn6193... {excerpt} ... The physicist was forced to concede a bet he made with American theoretical physicist John Preskill in 1997 as he unveiled his new theory on Wednesday. Preskill had doubted Hawking's theory that black holes destroy everything that falls into them. Hawking now says information can escape from within them. He revealed his new theory to a packed auditorium at a conference in Dublin, Ireland on Wednesday. New Scientist broke the news on 14 July that Hawking, at the University of Cambridge, had changed his mind about black holes after solving a long-standing paradox in physics. "I want to report that I think I have solved a major problem in theoretical physics," announced Hawking as he described his solution to the black hole information paradox. This paradox, ironically, stems from Hawkings own work. In the 1970s he proved that black holes lose mass by emitting radiation and eventually evaporate altogether. Science fiction But this conflicted with the laws of quantum physics, which state that information about what fell into the black hole can never be completely wiped out. Hawking previously argued that the intense gravitational fields inside the black hole were unravelling the laws of quantum mechanics, possibly sending the information shooting off into other universes. Now he thinks the information simply leaks out back into our own Universe. |

Science fiction
But this conflicted with the laws of quantum physics, which state that information about what fell into the black hole can never be completely wiped out. Hawking previously argued that the intense gravitational fields inside the black hole were unravelling the laws of quantum mechanics, possibly sending the information shooting off into other universes. Now he thinks the information simply leaks out back into our own Universe. |
Hawking is basically saying that the Blackhole horizon, the boundary that prevent matter and energy from leaving the blackhole is not solid but fuzzy, allowing matter to be trapped but not trapped permanently in the blackhole. He believes that the information that the matter and energy that falls into the blackholes leak out as hawing radiation, but this theory depends on if string theory is correct. As it stand according to relativity this is not the case, and we will not have a better understanding until we have develop a workin theory of Quantum gravity. |
