Click For Summary
The GBAR experiment at CERN aims to investigate whether antimatter behaves differently than matter in a gravitational field, specifically if it could potentially "fall upwards." Current scientific consensus, based on General Relativity (GR), suggests that antimatter should behave similarly to matter under gravity. If the experiment were to show otherwise, it could necessitate a significant revision of gravitational theories, potentially introducing a "fifth force" that affects matter and antimatter differently. However, any deviation from expected results would also challenge the weak equivalence principle, which is foundational to GR. Ultimately, the implications of such findings could revolutionize our understanding of gravity and black holes, but they would not necessarily invalidate GR entirely.

Is there a PF link explaining the "basic, medium, advanced" parameter of a post ? I originally thought it referred to the question, not the questor (which makes much more sense, if you think about it, of course).

Thank you to you @PeterDonis, for your precise and consistent answer !

@Vanadium 50 : Next time, express yourself more clearly and less evasively .
I have nothing more to tell you.

Have a good day,
Marilyn
