I just meant remove that mass from that location in space, and move it somewhere else. That area of the space was effected by the presense of the mass, and and if it was a one-time change how that space would know to return to not being effected. I'm not talking about all mass and all...

Isn't that something that has to be reconciled with QM?

I don't understand what you are saying here -- sorry. If "once" is enough per Einstein (and neglecting QM), then take the mass away abruptly. If the presence of the mass is not continually communicated, how does the local space know it is gone (maybe movement of mass VS presence of mass)?

I have a question about gravitation, that may be a "duh" question and apparent -- to everybody but me. Say that a mass effecting the geometry of space/time is the cause of gravitation, per what I understand about what Einstein said. Wouldn't that mean that the mass has to do this on a...

Good topic. The subject of light reflection and diffraction facinates me. This is what Richard Feynman says about it in his book "QED" (a grouping of lectures for a nontechnical audience). This passage isn't specifically about diffraction; it's about partial reflection of light through...

Isn't this the same phenomina that can occur during a solar eclipse, where it's fairly dark outside, and sunlight shining through the spaces between leaves on a tree cause many projections of the sun to appear on the ground below?

Hmmm .. I take back what I thought it would do, as if it did you could fashion a sort of Morse Code FTL communication. I don't know what it would do.

I'm interested in knowing what would happen in this setup, if anybody knows. I don't have a way to make a diagram, but the setup is pretty easy. Say that in a central location, call it L, you have a source of entangled photons that emit one to the left side and the other to the right side...

DrChinese, Question: How do we know these are truly random events VS pseudo random events of very close precision to random?

There is another way to look at this, that is actually quite amusing, to me at least. We don't know how, but we mostly accept it as "the way it is" and don't look any deeper into it when QM (nature) throws us randomness. Yet we almost become indignant and unaccepting (or, at least...

Please, feel free to read the passage from Dirac I cite, and either show where he's wrong or what he wrote doesn't apply to a physical meaning of superposition. The passage is only about 4 pages long. I'd type it up here but I'd have to get an OK from a board moderator first.

ZapperZ, Thanks, but I didn't see any links to the actual papers (not that I'd be able to understand them anyway) .. maybe I missed them though. I'll try to find them online, or maybe a trip to the library next week. Have you read the Paul Dirac chapter I wrote about?

ZapperZ, Were you being serious, or tongue-in-cheek??!?? Have any info on the "(i) the bonding-antibonding bonds in H2 molecule (ii) the coherence gap observed in the Stony Brook/Delft SQUID experiments." I'd like to read them.

RAD4921, Most of the people around here are a lot smarter about this than me, but since they ain't posting answers .. I'll try to. As far as I can see, this whole "conscious observer" thing rests on 2 dubious concepts: "Superposition" and "Collapse of the Wave Function". They're OK if you...

masudr, My mistake. I thought you were making a point for MP. I don't believe it either. But, sometimes I think I'm looking at it wrong. Some of the accounts say that the origin of inertia is the "combined mass of the Universe". It might make more sense to term it as "the distribution...
