By the way, I've been a member for quite a while now. I'm an auto mechanic by trade. But physics and all the unanswered questions it poses have been a passionate pastime for me. It is my hope and dream to one day develop an antigravity drive engine. That dream may soon become a reality. To make that dream come true some new ideas and new physics have to be developed. This thread really caught my attention. Because anti-light would be negative energy. That's a no no. But I don't care. I have an open mind. So it occurred to me that obviously my thoughts have crossed over into what kind of conditions would be necessary to support negative energy or anti-light as you put it. I see you have given thought to the existance of an eather. But we have to stick to actual physical observations when dealing with the concept. There doesn't appear to be any one universal frame of reference that we can experimentally confirm. So it isn't a big stretch to propose that all eathers are local and appear to be associated with large bodies of mass. But there are other more basic observations that I think you have to look at when dealing with the concept of anti-light. All the length in the universe is positive in value. Time appears to only flow in one direction. So I have given thought to the idea that length is only positive in value because of times arrow. So it would take some reinterpretation of existing phenomena to determine if there are any anomalies that would suggest times arrow could be reversed. I have to ask the question: How would a negative length phenomena manifest itself? Well, time might not flow as quickly within a region where negative length was present. That looks like a gravity field. Maybe. I have been entertaining the idea that mass itself may be responcible for the slowing down of time. But then what is the basic cause for times arrow? I'm guessing on this one. But I'm putting my money on the nuclear reaction within our sun as the cause of the local direction of time. Specifically, the mass of the sun is being converted into energy at a very small but continuous rate. So locally the mass is decreasing in value. This is going on all over the universe. So if times arrow is based upon a decreasing local value of mass then a negative time arrow might be generated with a nuclear reaction where mass increases in value during a nuclear bonding scenario. I do believe elements above iron on the periodic table would fit this requirement. Now that is food for thought for a steady state universe theory.
So basically I have described three types of spatial states. Only two of them appear to be present in our universe. but my current area of experimental research has lead me down a very narrow path to a more basic understanding of what mass is: A timeless state of length. And more specifically how to simulate the effect of mass. That is an area of current experimental research for me. So I will say that manipulating mass so that it increases in value locally may generate a times arrow that moves in the opposite direction. A necessary condition for anti-light. Negative energy, or even a time machine may be the outcome. So maybe that's why our science doesn't really have a comprehensive theory that ties it all together. All those that figured it out have constructed time machines and left.
