  1. What if I were to have a ball say, and I had inside of it a clock. And that clock ticks at every standard second depedning on how gravity effected it (it just ticked normall). And Ialso had a power source so that the clock would last a long time (i.e. a gerbil), and then I were to cover the ball in an anti-gravity paint, thus neutralizing gravities effect on the clock. If I then were to pull the clock out 5 minutes (as viewed by me standing next to this ball covered in anti-gravity paint), what time would it be at? And would it be the 'standard' time?
  2. IF you want to know how this relates to QED or QCD I could help... otherwise I'm lost
  3. "the index of refraction is different along different crystal directions." I would think different molecular bonds of the same atom would make that different, yes.
  4. Look up Noble Gas Configuration

    helium

    the electromagnetic pull on the electrons from the nucleus of the helium atom is too strong for it to want to share anything with anybody. that is why it's electro negativity is 0
  7. Uh... let me a find a picture. You need to forget the Bohr Model of the atom, it is inaccurate. Electron orbitals do not orbit in circles. They look like that. First fillign up the 1s level, then the 2s2p then the 3s3p3d etc etc It's called electron configuration, look it up on wiki.
  8. But graphite and diamonds are bonded differently. Clarification: Graphite is made of Carbon. The carbon is however only bonded three time, leaving 2 unused valence electrons. Diamond is bonded 4 times. That is why it is stronger.

    Speed of light

    You could never go the speed of light, because f you did you would have infinite mass.
  10. Virtual particles are not really particles, we just use a particle model to make our calcuations easier. Besides, if space was infinitely indivisible, and the point-like particles reside in them. Wouldn't the smallest bit of space be completely filled up by the smallest particle, with the purest density (i.e. all space is taken up, since it is the smallest particle in the smallest space), wouldn't the gravity of that point be enough to form a mini-black hole?
  11. The fundamental nature of the photon is believed to be understood theoretically; the prevailing Standard Model predicts that the photon is a gauge boson of spin 1, without mass and without charge, that results from a local U(1) gauge symmetry and mediates the electromagnetic interaction. However, physicists continue to check for discrepancies between experiment and the Standard Model predictions, in the hope of finding clues to physics beyond the Standard Model. In particular, experimental physicists continue to set ever better upper limits on the charge and mass of the photon; a non-zero value for either parameter would be a serious violation of the Standard Model. However, all experimental data hitherto are consistent with the photon having zero charge and mass. The best universally accepted upper limits on the photon charge and mass are 5×10−52 C (or 3×10−33 times the elementary charge) and 1.1×10−52 kg (6x10-17 eV), respectively.
  12. I didn't say that the actual photon slowed down. I said the speed of light did. The equation for distance is a simple, D=RT So therefore Speed = Time / Distance Therefore if it takes a few of those quanta packets of light longer to get to the other side, they have essenitally slowed down.
  13. But everything is a medium. There is no vacuum.

  15. the speed of light is not constant as it moves from medium to medium. When light enters a denser medium (like from air to glass) the speed and wavelength of the light wave decrease while the frequency stays the same. How much light slows down depends on the new medium's index of refraction, n. (The speed of light in a medium with index n is c/n.) The index of refraction is determined by the electric and magnetic properties of the medium. For air, n is 1.0003, for ice, n is 1.31, and for diamond, n is 2.417. The bending of the light you mentioned upon entering a denser medium is how lenses work. Although the speed of light is no longer constant when we think about different media, we do know that light always travels fastest in a vacuum. Nothing can reach speeds faster than c. Thus from our equation v=c/n, n must always be greater than 1. Light moves slower through denser media because more particles get in its way. Each time the light bumps into a particle of the medium, the light gets absorbed which causes the particle to vibrate a little and then the light gets re-emitted. This process causes a time delay in the light's movement so the more particles there are (the more dense the medium), then the more the light will be slowed down.
  16. Photons are not composite. And it is 3 quarks, an antineutrino and an electron.
  17. Preon models explain some of the patterns of leptons but they come up short on several accounts: Fermion families, preon models accomadate any number of families. Why are there only three n nature? Matter vs Antimatter, GUTs naturally predict proton decay and CP violation, necessary ingrediantes for explaining the matter-antimatter imbalane in the univserse, no one has yet figured out how to incorporate these ingredietns into preon models. Fermion masses, as we have seen preon models give us no help there.
  18. A fission reaction works by bombarding an unstable nucleus with a particle causing it to split in two(or more) smaller more stable nuclei, also it emits a few neutrons. The neutrons then hit another atom, etc etc, causing a chain reaction.
  19. It doesn't go down to zero size. It's gravity isn't infinite.
  20. The strength and type of bonds all depend on electronegativity. If there is a 0-5% difference in electronegativity, it will form a non-polar covalent bond. 5-49% It will form a polar covalent. 50-100% it will form an ionic bond. Or so I've been told.
  21. What if I were to have a ball say, and I had inside of it a clock. And that clock ticks at every standard second depedning on how gravity effected it (it just ticked normall).
