    Planet Push
Click For Summary
The discussion centers on the nature of gravity, questioning whether it is a push or pull force. Participants explore historical theories, particularly Le Sage's idea of particles exerting pressure, and express skepticism about the traditional pull model of gravity. They highlight that gravity could be viewed as a fictitious force resulting from non-inertial frames of reference, suggesting that Earth's surface accelerates outward. The conversation also touches on the challenges of reconciling alternative gravity theories with observational evidence. Ultimately, the prevailing view leans towards gravity being a pull force, despite ongoing debates about its true nature.

I don't know that pull gravity has shown any more evidence than push theories. They'd behave mostly the same.
What about the drag force mentioned on WP?

So you're conceptualizing this push-gravity as a type of radiation that is blocked by mass where more mass = more blockage?

Essentially. I'd lean towards the most elementary particles being the ones that absorb it to some degree, or are affected by it. Whether it's the radiation actually running into matter, or possibly just interacting with it by passing close enough by, I don't know. Just thinking out loud.

Sorry. Just making sure I'm not having a nightmare.

PF is entertaining discussions on push gravity?

What's next? Calls for submissions of PMMs?

I know, this is all speculation, but that's what science does, it thinks, looks at evidence, makes predictions, tests those, thinks again, etc...
True, but that's not what PF does. We don't generate new science, we teach existing science. Thread locked.
