Re: will solar sailing work?

"Hmmm.. but doesn't it follow we then have a red shift mechanism that
is not distance/recession related?
(I am quite out of touch with current cosmology.)

Mmmm, very interesting.

OTTOMH (off the top ...): the amount of red shift from this mechanism would also be distance (linearly? *) related, and add to the expansion of matter.

* photon collision with receding matter results in a greater red shift and with approaching a blue?

bc who must ask his cosmologist friends.

p.s. A recent colloquium at UCSC discussed the radiometer. The speaker described his "real" ones. The vacuum necessary was surprisingly poor (vac-ion pump attainable). He also spent some time discussing the mechanism of the wrong way one. (Is this deja Vu time?)

In the articles linked below, Gold from Cornell claims solar sailing won't
work essentially because it would violate the 2nd law of thermodynamics.
