Dale replied to the thread Undergrad Why is gravity a fictitious force?.You missed the point. I was not claiming that either Minkowski spacetime or Schwarzschild spacetime are realistic. They are just clear... -

See the bolded addition in the quote above. Without it the statement is false. Again see the bolded addition. I think both additions... -
Dale replied to the thread Undergrad Why is gravity a fictitious force?.Both Minkowski spacetime and Schwarzschild spacetime are vacuum spacetimes. They have the same energy-momentum but different boundary... -
Dale replied to the thread Undergrad Why is gravity a fictitious force?.The boundary conditions. -
Dale replied to the thread Undergrad Why is gravity a fictitious force?.Sure one can. One doesn’t need to bring in irrelevant topics to hijack a thread. This is utterly irrelevant to the discussion here... -
Dale replied to the thread Undergrad Why is gravity a fictitious force?.Sure, that is a matter of definitions and categories. Nevertheless, the tidal force is the physical part of gravity, the part that does... -
Dale replied to the thread Undergrad Why is gravity a fictitious force?.And once there is some actual evidence supporting your preference then it will be an acceptable topic for PF. But even then it would be... -
Dale replied to the thread Undergrad Why is gravity a fictitious force?.We are already in that situation with GR alone. So why should we hypothesize about unknown possible future theories when we can already... -
Dale replied to the thread Undergrad Why is gravity a fictitious force?.I won’t argue against that. In either case, the local gravitational force, like fictitious forces, is not measurable either way. It can... -
Dale replied to the thread Graduate How is literally EVERYTHING in physics not binary?.Because we have found through years of experience that this is the best way to keep the signal to noise ratio high. -

The problem with "sharing what you know" is that unless it commonly accepted, you will need citations. Here's an except from the Terms... -
Dale replied to the thread Graduate How is literally EVERYTHING in physics not binary?.All posts on PhysicsForums should be consistent with the professional scientific literature. What you personally theorize is not... -
Dale replied to the thread Undergrad Why is gravity a fictitious force?.Which is not a professional scientific publication. And this remains a false statement. Many seminal observations were made prior to the...
