    How often does mass effect space

    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...

    Even another 2-slit experiment setup

    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...

    Stephan's Quintet

    http://www.spitzer.caltech.edu/Media/releases/ssc2006-08/" [Broken] The Spitzer Telescope views Stephan's Quintent. I remember reading a writeup Halton Arp had about this a time back (please, this is not the place for "shots" against him), that he thought the bottom left galaxy was actually...

    Cause of this diffraction?

    I love simple phenomina like this .. finding something "everyday" simple, and then trying to explain it or find a cause in scientific terms. I say it is diffraction, but I'm not sure. Here's the setup: In a darkened room light a small source of light, like a candle. Close one eye and with...

    Horizons Misson - Questions

    Horizons Misson -- Questions I looked for a topic on this, and couldn't find one. If anybody else has questions about it, please feel free to post them here. If anybody knows ... I looked on the Horizons' web site but didn't find (easy) answers. In relation to the other two NASA probes...

    Causes of Diffraction Patterns

    Take a two-slit diffraction experiment. From what I've read or gathered, it is supposed to be caused by the geometry of the setup, and the frequency of the light (maybe a few more things). But, it is talked about in terms of the geometry, and no cause attributed to interactions between the...

    Dark Matter & Energy/Mass of False Vacuum

    I'm not trying to advance a pet theory here .. it's really just a question. Why don't physicists serious consider the possibilty of energy/mass contained in the false vacuum as the source of Dark Matter? At least I've never heard of a serious one in these terms. Real particles and their...

    A way out of singularities?

    I may look at it wrong, but when I think of a Black Hole, I think of the 3 spatial dimensions we know of compacting to a point, rather than space folding back on itself (I guess it could be just semantics though). And when you think of a singularity, I think it is inherent in that process you...

    Questions on Mach's Principle

    Say you have a gyroscope, rotating in the ole' proverbial Star Trek "dead of space", far enough away from any single/multiple point of mass, to where the gravitational attraction of the Universe as a whole would be expressed. Or at least at a point to where the local bodies gravitational...

    Smith-Percell Radiation

    I did a board search here and didn't find anything on "Smith-Percell Radiation". It is an interesting phenomina to me, because it was thought up about 50 years ago, and scientists are still arguing over the exact mechanism of its source. It is described in a book I read a couple of years...

    Can a substance refract light

    Can a substance refract light to such a degree that the angle the light is bent to be an acute angle? The reason I ask: Take for instance Moon shine (not the kind that you drink). The answer you most often get is that it is sunshine reflected off the Moon, to your eye. That can't be the...

    Questions on Refraction

    I've seen the diagrams they write up talking about refraction for ages .. where a light ray goes into a different medium of higher index of refraction at an angle, and then the light ray is bent. And that is used to illustrate Snel's law. I guess I haven't paid close enough attention! I'm...

    Question on Virtual Particles

    For the purposes of this question, assume there are gravitons and they are the carrier of the gravitational force. I could use one of the other forces and leave out gravitons, but it's easier for me to envision this question using a very low strength force. Q1) -- For gravity to deflect the...
