I have a mentor at work, who wrote a paper in the past regarding light and relativity. I am an aerospace engineer by training and a system administrator/programmer by trade, so I know a little bit about physics and relativity, but not enough to critique this paper.
The paper in question is Hall Photon Theory, which is a rather unsettling paper, written looking at physics through the lens of the author's personal experience.
It is clear that light is affected by gravity (gravitational lensing, etc.) and that light can influence matter (solar sails, light "pressure", etc.), so it seems that what he claims could be feasible, but I want to throw this out there to see what people who know a good deal more about this have to say.
So, my question, can light affect gravity/matter?
Since, I am getting answers all over the board, let me increase the precision of my question:
Are the hypotheses presented in the aforementioned paper, namely that cleverly used light can produce anti-gravity/anti-intertial fields, provably false? And if so, can you provide that proof?
