Random thought of today...
Sometimes there's discussion of dark matter and nobody knows what it is...
I'll take a guess. What if dark matter is photons? Yeah, probably seems silly to some people. But why not. If photons can be re-directed by gravity, then that would imply that they do have mass. (Albeit close to infintesimal.) If they didn't have mass, they would go straight past a gravitational object. (Of course someone would argue that space is being bent, but lets say for counter arguement that mass/inertia is how strongly something is attached to space too.) So if you were to figure out how much every single photon in transit and including those currently not being detected would add up to in mass value... I'm curious as to how that compares to value estimates for dark matter.

Another random thought - on a mostly unread blog.
After reading some random stuff, this is how I think relations between anything in space could be described:
(X, Y, Z), t , (Xi, Yi, Zi), ti
Thus there are the normally observable portions of space X, Y, Z, definable at time t. But then there are the "imaginary" space components Xi, Yi, Zi and the ti for an imaginary time. The "i" component of these elements is more or less the same "i" seen in math using complex numbers. If you were to square their value, you'd see a negative real number.
I almost suspect that gravity would be the resultant of an imaginary square, since it is only observable as an attractive force. There might not be any "anti-gravity", but perhaps knowing how the relation of an imaginary space component ties into a standard one might allow you to zero out gravity or produce a strong attractor. (Still the net effect of a combined zeroing the influence of a natural attractor and production of an artificial accelerating force might look like antigravity in a practical sense.) Also this might be interesting for quantum particles that blink in and out of real space - squares of imaginary stuff would blink into negative components of real space. (Not necessarily antimatter, but it might be left handed where normally such things are right handed, etc.) Gets a little too funky for me to think of in detail, but that scratches the surface at least.
