The discussion revolves around the potential violation of the Equivalency Principle at the quantum level, exploring whether this is a genuine phenomenon or merely a conceptual trick. The scope includes theoretical implications, speculative reasoning, and references to experimental possibilities.
Participants express differing views on the implications of the potential violation of the Equivalency Principle, with no consensus on whether it is a significant issue or merely speculative. Multiple competing perspectives remain regarding the interpretation of the phenomenon and its theoretical implications.
The discussion highlights limitations in current theoretical frameworks and the dependence on future experimental results to clarify the issues raised. There is an acknowledgment of unresolved mathematical and conceptual challenges.
Isn't that just a modification of gravitational force? Instead of varying gravitational mass, we could just add a force correction, that will do the right thing.http://www.technologyreview.com/blog/arxiv/25331/
K^2 said:It's probably going to be up to Quantum Gravity to answer this question.
The article claims that the experiment could probably be done within a few years, so it doesn't seem to be a purely theoretical issue. I'd guess the authors are claiming there's some experiment that could be done in the 1G gravity at Earth's surface that would give different results than what quantum field theory would predict would be seen by an observer accelerating at 1G in flat spacetime.nismaratwork said:For now, it's as good as dividing by 0 however, to use the OP's metaphor, don't you think? It's just, "not covered in the material" that currently exists, leaving only speculation and guesses until the next round of predictive theories comes around.
