    Which interpretation is your favourite?

    Emitter and Absober are exactly the charged particle that radiate the wave. E.g., electron emits/absorbs a photon during transition to another energy state. See http://en.wikipedia.org/wiki/Wheeler–Feynman_absorber_theory" . The idea of Transactional Interpretation came from this theory.

    Which interpretation is your favourite?

    I Like Transactional Interpretation. - It explains the whole process of "wave function collapse". Wave function does not magically disappeared after it is collapsed. It canceled out as the transaction is completed. - Wave function is physically "real" wave. - It's time symmetric. - Observer...

    High School Why do astronauts describe the smell of space as strong, metallic, and unique?

    It may be the smell which come from the space suit after it has been exposed to vacuum and radiations from the space. I think they actually has smell "something", not a sensory perception problem.

    Medical Are Eye Floaters Normal?

    You've got eye floater. http://en.wikipedia.org/wiki/Eye_floater It's not normal if you have too many of them. There are several possible causes. Usually a sign of eye regression. You should see a doctor. I saw a man post in another webboard that he and his family can see dead people's...

    Graduate What are the effects of traveling at light speed on aging and time perception?

    If you travel with the speed of light, you will see the infinite length contraction of space in the direction you are traveling. So you get to your (final) destination in no time. You will also suffer the infinite blue-shift radiation coming head on. And see nothing else in any other...

    Undergrad Why does a fluid exert an upward force?

    The force/pressure exerts from every direction around the object. But the pressure get higher when you get deeper in the fluid (thanks to gravitation). So the net force is upward. Try using the suction cup under the water. You can get the net force in any direction exactly like when using it...

    Graduate Can Entanglement Survive the Destruction of One Particle?

    Entropy is the amount of information. It is approximately the least number of bits need to code the information. highly ordered system ~ highly redundant data ~ low entropy highly disordered system ~ low redundant data ~ high entropy

    Does a physical theory need to be self-consistent?

    Hi selfAdjoint, I don't claim that Fereyabend's argument is about self-consistency. And adding "new hypothesis" does not necessary mean finding a new theory. But *my question* here is about self-consistency. Talking about other thing, such as consistency between...

    Does a physical theory need to be self-consistent?

    What you are talking is about the theory that failed to satisfy the fact, and has nothing to do with self-inconsistency. Please carefully read the definition of "Self-Inconsistency" again. Right, that is not inconsistency in QM. I never said that I'm not bothered by that. I'm talking...

    Does a physical theory need to be self-consistent?

    self-consistent = contains no valid proposition that can prove true and prove false under the same theory 1. Does a physical theory need to be self-consistent? Why? 2. Is it possible to accept a theory that agree with all facts but contain inconsistencies? 3. Is a self-consistent theory...
