starship-design: Dark Matter
Hi all; no one's heard from me for awhile 'cause I've been busy becoming
Dr. Ken. Of course that's no reason to take me any more or less
This is the comment which brought me out of "retirement":

I don't know if anyone remembers me going off about time-reversed matter
a few years back, but I've kept thinking about it. In fact, I've
written a full paper summarizing my ideas. The basic motivation is to
give the universe the same symmetries that the laws of physics already
have. The basic conclusion is that a large portion of dark matter
should be time-reversed photons (with a future boundary condition, or
"cause", rather than the normal past boundary condition). If I'm right
(which I'm almost certainly not) these photons would interact with
normal matter in a very strange fashion, releasing energy when they hit.
I've devised an experiment that's capable of proving me wrong, but apart
from that there's no objective difference between this work and a lot of
crazy cosmology out there, so I don't expect anyone to take me too
Anyway, the full paper is now online at:
Figure 4e shows a simple schematic of how this "dark matter" might
interact with ordinary matter.
If you get bogged down in the paper (a common occurance), a quick summary
of the concepts can be found here:
Hope it's somewhat comprehensible (and that it doesn't ruin my career as a physicist!)
P.S. I now work with the guy whose thesis concluded that axions exist (this
was the work done in Italy that someone mentioned). He told me that he made
a terrible blunder in his data analysis, and when he re-did the calculations
the axion effect mostly went away. He had already graduated at that point,
but still wasn't too pleased to learn his thesis was totally wrong...
