The black hole would disappear almost immediately. |

If particles can vanish into other dimensions, that must mean energy can be transferred to other dimensions. So could all the energy in our universe actually have come from another reality set apart from our own existence? I always found it intriguing the first time in high school chemistry finding out that electrons, according to the "Rule of Uncertainty", can be in two places at the same time! Really boggles the mind to know that what we think we know ain't even a FRACTION of what's really out there! |
I'm pretty sure that the uncertainty principle only states that you cannot measure both the position and momentum for a system at the same time. Not that electrons can be in two places at the same time.
Also LOL at half-life references because I kept thinking about half-life last week when my professor was teaching us about zero point energy. |

I swear to you that the electron's position cannot be measured because it appears to be in more than one place at the same time. That's why the physicist who made up the Uncertainty Principle also made up the "Electron Shell" diagram with all the valences and stuff. The thing I love about quantum physics is that omnipresence for subatomic particles isn't a far out idea. It's REALITY...:eyes: :eyes: |

Uncertainty principle states that you cannot measure the position and velocity of a particle at the same time. If you want to measure the position, you need to shine light in order to see the particle. But the particle will absorb the light photons (which is energy) and that will change its velocity (or momentum if you multiply the particle's mass with the velocity) in a manner which cannot be predicted. And vice versa.
The implication of the uncertainty principle is that electrons and other subatomic particles behave sometimes as waves and sometimes as particles. The fact that electrons appear to be in two different places at one time, was demonstrated through the famous "two slit" experiment which demonstrates the phenomenon of interference of light.

You can swear whatever you want, but I'm almost finished with my chemistry degree and I know for a fact that the uncertainty principle only states that you cannot measure the momentum and position at the same time. And it isn't because electrons are in more than one place at a time.
I've taken statistical mechanics so I understand the implications of the electron shell. The electron shell diagram shows areas where you have a high probability of finding the electron. Electrons are fermions so you use the Fermi-Dirac distribution for calculations. It is all based on probability and statistics but that doesn't mean something can be in two places at the same time. |

What about this experiment?
| quote: | The double-slit was voted the most beautiful experiment of all time in a 2002 poll by Physics World, published by England’s Institute of Physics. Although each electron seems to go alone through one of the two slits, at the end a wavelike interference pattern is created, as if the electron split while it went through the slit, but then was subsequently re-unified. But if one of the slits is closed, or an observer sees which slit the electron went through, then it behaves like a perfectly normal particle. That particle is only at one position at one time, but not at the same time. So, depending on how the experiment is carried out, the electron is either at position A, position B, or at both at the same time.
But Bohr’s Complementarity Principle, which explains this ambiguity, requires that one can only observe one of the two electron manifestations at any given time - either as a wave or a particle, but not both simultaneously. This remains a certainty in every experiment, despite all the ambiguity in quantum physics. Either a system is in a state of "both/and" like a wave, or "either/or" like a particle, relating to its localisation. This is, in principle, a consequence of Heisenberg’s uncertainty principle, which says that given a complementary pair of measurements - for example, position and momentum - only one can be determined exactly at the same time. Information about the other measurement is lost, proportionally. |

| mwahaha...I love the guys who came up with the double slit experiment. It really is mind blowing. If you fire one electron at a time, the ONLY way an interference pattern could possibly be created is if each electron travels through BOTH slits at the same time, and INTERFERES WITH ITS OTHER QUANTUM SELF before hitting the wall. ;) |

I think you are misunderstanding the experiment.
Like I said already and so did Omega. The electrons 'appear' to be in two places at the same time due to the particle/wave duality causing interference. Not because it is actually in two places, but because it it is a particle and a wave. This particular phenomena is caused by the wave nature. |

This thread delivers...
...electrons that appear to be in 2 places at the same time but are really not. |
