Ever toss a hand full of metal, glass and plastic into a mud puddle--come back a few million years later and start digging up microwaves, cell phones, mp3 players, etc.? If not, then you have a faith greater than it takes to have faith in aliens or God ... our existence is about as strange a mystery as you will ever find. I just love those with over-simplified explanations ... occams' razor seems to dull a bit on this problem. JS |

Why were no heavy elements created during the Big Bang? -- 73, Cecil, w5dxp.com Cecil Heavy elements are created from precursors that exist prior to the supernova. All fusion reactions up to Iron result in the creation of energy. This is what keeps a star from collapsing under its gravitational mass. Once a star reaches the stage where a given proportion of the core is composed of Iron, not enough energy is given off to prevent the star from a catastrophic gravitational collapse. It is the energy from the gravitational collapse that creates the heavy elements and if the star is big enough, a nova or supernova. I seem to recall that the big bang by comparison resulted in an initial state that was composed of something in the order of 97% Hydrogen and 3% Helium. The elements condensed from an expanding cloud of sub atomic particles as temperatures (or energy levels) dropped with the expansion. By the time individual atoms had condensed, the particles must have been too far apart to become involved in further fusion reactions until they coalesced under gravity to form stars. Each new generation of stars contains a higher level of Helium (and heavier elements) than the last and this is used as an indicator for how old a star or galaxy cluster might be. Mike G0ULI |

If photons were apparently travelling at 1.7 times the speed of light in air, they clearly must have been exceeding the speed of light in a vacuum. This result was observed using visible light. Current theory is usually quoted as nothing can travel faster than the speed of light in a vaccum. It is probably more correct to state that objects with mass cannot exceed the speed of light in a vacuum. Photons, having no mass, are not necessarily subject to this rule and seem to be observed travelling at superluminal velocity under certain very specific conditions. If the photons are tunnelling and travelling faster than light in a vacuum, it does not necessarily mean that any laws have been broken. One way of imagining a way in which this could happen is if a block of material is energised to a high energy state. Photons are continually fired into the material and are absorbed one by one with atoms within the structure absorbing each new photon. At some point, the material becomes completely saturated and cannot absorb any more photons. When the next photon hits and is absorbed, a shockwave propogates through the material and a photon is emitted from the opposite side travelling at the same speed and in the same direction as the original absorbed photon. Stability is restored and energy is conserved. But, it is the shockwave that has propogated faster than the speed of light and it is not the original photon that entered the material that is emitted. The emitted photon will contain exactly the same properties as the absorbed photon and the two would be indistinguishable. So the photon appears to have been transmitted through the material at faster than light speed, but no laws have been broken. A Newtons cradle can help with visualising how this can happen. Mike G0ULI Mike, You had me fooled. It appeared that you might actually know something. But that response bent the needle on my bull**** meter. 73, Gene W4SZ Actually that response is very credable, It is analogous to what happens when electrons travel in a wire. Put an electron in one end of a wire and one pops out the other end almost instantaneously even though the actual speed of electrons flowing ththrough the wire is very, very slow. Jimmie |

Entangled particles can not be used to send _information_ at a speed greater than the speed of light. From: http://www.socialtext.net/wired-mag/...es_communicate --Quote: How do entangled particles communicate? One of the zanier notions in the plenty zany world of quantum mechanics is that a pair of subatomic particles can sometimes become “entangled.” This means the fate of one instantly affects the other, no matter how far apart they are. It’s such a bizarre phenomenon that Einstein dissed the idea in the 1930s as “spooky action at a distance,” saying it showed that the developing model of the atomic world needed rethinking. But it turns out that the universe is spooky after all. In 1997, scientists separated a pair of entangled photons by shooting them through fiber-optic cables to two villages 6 miles apart. Tipping one into a particular quantum state forced the other into the opposite state less than five-trillionths of a second later, or *nearly 7 million times faster than light* could travel between the two. Of course, according to relativity, nothing travels faster than the speed of light - not even information between particles. Even the best theories to explain how entanglement gets around this problem seem preposterous. One, for example, speculates that signals are shot back through time. Ultimately, the answer is bound to be unnerving: According to a famous doctrine called Bell’s Inequality, for entanglement to square with relativity, either we have no free will or reality is an illusion. Some choice. --end quote 73, Cecil, w5dxp.com Very interesting if you limit yourself to a three dimensional universe. In a 3 dimensional universe these particle may be adjacent to each other. |

From what I got of it nothing is what exist beyound the boundries of the universe and empty space would have to exist within the universe. Outside the universe would be "absolute nothingness" as opposed to nothing being in an empty bucket within the universe. It certainly depends upon the definition of "nothing" that is being used -- 73, Cecil, w5dxp.com |

We could start with: Where did all that energy come from that caused the Big Bang? Why did it wait until the time of the Big Bang to explode? How long was a second before the Big Bang? :-) Well we could Cecil. But before we do, It would be cool to ruminate on a universe that has no restrictions on energy. If energy isn't conserved, that would be the case. Your big bang questions only hint at the possibilities. Arthur C Clarke had some interesting thoughts on some of the possible issues from just zero point energy extraction - which does not violate the conservation of energy. See the heat crisis from the space oddysey books. - 73 de Mike KB3EIA - |
