  1. The measurement result can be sent any way you want - digital signal along an optical fiber; carrier pigeon. It's because this communication is necessary that means that no information exceeds c. The entanglement is the "tie" between the two original particles.
  2. There are things about economics that can be studied scientifically, but economics as a whole is not a science.
  3. For an ideal gas, PV=nRT Oxygen isn't ideal, but it will give you an idea. T must be in Kelvin. A better value can be found using this formula.
  4. Oh, Please. Even Answers in Genesis thinks the Paluxy tracks are not credible
  5. It was a "what-if" question. Nobody was actually proposing that it could happen. Sheesh.
  6. E=mc2 c2 = 931.5 MeV/amu There are 6.02 x 1023amu/gram, and 1.6 x 10-19Joule/eV
  7. It sounded like you were saying that the absorption by a perfect blackbody was somehow different than absorption by a real object in a way other than the fraction of photons absorbed.
  8. Partial reflection just means that some of the photons were absorbed, just not all of them. The energy transfer process is the same - ultimately the object will heat up.
  9. What are the possible interactions an electron or photon can undergo?
  10. Evidence, please. Here is more on the subject.
  11. I agree that you are seeing diffraction, but gravitational lensing has been observed. You need a big mass, though. (I think a Google on {gravitational lens quasar} would yield good results)
  12. Have you used an actual physics example anywhere?
  13. It's not. The "glass flowing" stuff is not credible - it's an urban legend. Glass just doesn't undergo the same transition, so you don't get the same indications about when it's a solid or liquid.
  14. Whose contention is it that an extant species is a common ancestor to all vertebrates? What has prevented it from speciating lo these hundreds of millions of years?
  15. Sayonara's post about mating for large willie size reminded me of this Somewhere, sometime, there was a man who decides that it's time to marry, but wants his bride to be pure and unspoiled by the world. So, much like Diogenes and his search for an honest man, he went on an epic quest for a pure woman. As a test, he would drop his shorts and ask, "What's this?" Invariably, the response would be, "That's your willie!" at which point he would move on to the next candidate. One day, though, the answer was, "I don't know." He knew this was the woman he should marry, and did so. On their wedding night, he asked again, "What's this?" And the response again was, "I don't know." At which point he informed his new bride, "This my dear, is a willie." Whereupon she burst out laughing. "Be serious! Willies are black and about three times bigger!" or, alternately: Q: What's white and 12 inches long? A: Nothing
  16. My table "levitates" metal objects all the time. Just not very heavy ones. It's levitating some small copper & zinc objects right now. Not very high above the wood, however.
  17. Protons and neutrons couple by the strong nuclear force. There is an energy dependence of nucleons on spin, but that is at least in part a consequence of the Pauli exclusion principle (e.g. in Tritium, the neutrons would have to have anti-aligned spins to be in the same energy level)
  18. The magnets are doing no work and expending no energy. Just as my table, in holding up my lamp against the pull of gravity, is expending no energy. Or is my table an infinite energy source?
  19. It's called Kleiber's Law. Basically it goes as C * M3/4, where M is mass and C is a constant that is different for different types of animals. It seems to work for metabolism, heart rate, and lifespan. Lung surface area and encephalization quotient follow the same relationship, but all these things are inter-related, so scaling the same way shouldn't be too surprising. So birds would have a different constant than mammals which would be different from amphibians.
  20. The antineutron will have the opposite magnetic moment of the neutron.
