  1. Here is a response I received on another forum. Is this accurate?
  2. That's too bad.. What was the problem? I saw "spam" in the announcement thread... Which doesn't seem accurate...
  3. Interesting. So at what point will massive objects fall at different velocities towards the center of a planet? Can this be determined? Would a car and a mountain sized mass in earth's orbit still fall at the same rate towards the center of the earth? Is there a known point which photons (wrt their energy) will start to behave differently in a gravitational field? Thanks
  4. But a 400 GeV photon might behave differently in a planets gravitational field than say a 3 eV photon? Or no?
  5. Have there been any experiments done to measure the vacuum constants? I've been wondering about a variable magnetic and electric constant lately. Which wouldn't necessarily mean the speed of light changes, but could just be similar to red/blue shifts... What are the chances that gravity (or velocity) changes the magnitude of the vacuum constants (magnetic and electric).
  6. Because photons follow the curved space-time created by earth's gravity. Here's another question for someone else.. Do higher energy photons curve more, less, or the same as lower energy photons (in earth's gravitational field)? Photons still travel at the speed of light in earth's atmosphere, but they're absorbed and emitted by molecules in the atmosphere at a slower rate than in free space.
  7. It is hard to understand what you are trying to say.
  8. Darn.. I was hoping for something easier. Lol. Would it be easier (or possible) to determine the time it takes a single hydrogen atom to emit a photon from the time it's absorbed, using the refractive index? (instead of a larger quantity)
  9. I just found it .. It is: 1.000132 .. How could one determine the rate which photons are absorbed then emitted with this? Thanks in advance.
  10. where could I find the photon propagation (measured) rate through hydrogen gas? Thanks.
  11. Oops, I meant without experiment
  12. How would someone determine the time it takes a photon to be absorbed and emitted by an atom (the refractive index)? In hydrogen for example.
  13. At the end of this section: http://en.wikipedia.org/wiki/Magnetic_constant#Historical_origin_of_value_of_.CE.BC0
  14. Why can't vacuum permeability/permittivity be measured? I've read that they can't be measured .. is this simply because "pure vacuum" isn't attainable?
  15. I don't think matter or space can exist without time either. Can anything exist without it? .. Time is probably the most fundamental aspect of the universe..
  16. Good point. I was mostly curious if some sort of resonant cavity could have been created in the tube allowing disassociation, but probably not..
  17. I just found this (sketchy) paper on the web, and I'm curious why RF disassociation of h2o isn't considered to be possible? Let me know what you think. http://www.rustumroy.com/Scans/Observations%20of%20polarized%20MRI%20vol%2012%20is%201.pdf Thanks.
  18. I'd say space-time is more of a substance like mass.. Which can't exist without space and time, right?
  19. No. If moving at 'c' its time would stop, I believe.
  20. The term "cold fusion" is just coming from the media as far as I can tell.. It sounds like the scientists aren't sure what is happening (?). There's not much information to go on... But it's too bad most scientists are so concerned about their reputations, that they won't even look into a potentially new nuclear process. At the same time, if the experiments are valid and something new is going on, they could have a lot to gain if they figure out what is happening.
  21. True, but it still seems strange most physicists will dismiss these experiments as none sense without ever looking into their validity. Anyone have more details on the SPAWAR cold fusion experiments? All I could gather was they used special Pd-D electrodes (plated in the presence of Deuterium gas) for electrolysis on heavy water, and the process would not work with normal tap water.
  22. You can make a resonant cavity out of ice just as you can a wine glass. Ultrasonic vibrations can probably break or melt ice as well.
  23. This is the best description I could find .. about 13:00 into the video, the SPAWAR scientist talks about what they did.
  24. Have there been any details published regarding the US Navy's experiment on LENR or 'cold fusion'? What does it have to do with 'nano machines'?
  25. I was wondering about this the other day.... Here are some ideas: 1.) By the sound of the "crack" most static arcs make (to get a rough idea of the power) .. I went down a slide once and the static shock actually hurt.. The "crack" was so loud you could hear it on the other side of the park. (i wonder if this could work for lightning as well)? 2.) How about from the length of the static electric arc?
