Why Gravity is NOT a Force

[PHC1]

I am struggling with the traditional concepts and definitions of Gravity being a "force". Maybe some of our members can elaborate on this? https://youtu.be/XRr1kaXKBsU

Gravity is...hard to explain. Period!

Seriously, even Neil agrees.

The Einstein version of gravity (which is not a force) is that the Earth's mass pushes into or creates a dent if you will in space-time around it. That in turn creates the effect we are used to calling gravity.

Where I am having a hard time is that the Earth is a sphere so the acceleration of the Earth into the object (as is often depicted in these videos) instead of the object falling into the Earth just doesn't make sense. It creates a problem for the other hemisphere in my mind since the Earth can not be accelerating out in every direction as a sphere

I personally think but I could be wrong is that the Earth is not accelerating into the objects on it but that the objects are constantly "falling into" that same space-time disturbance (curvature of space-time) the Earth's mass creates. The constant falling is what keeps us and everything around us like the oceans for example grounded. That resolves the problems, at least in my mind. I am probably wrong though.

I always get a kick out of the Joe Rogan episodes. Just a down to earth, thinking guy who happens to be a martial artist and a very good talk show host with more intelligence than an average Joe.

Here is Joe Rogan with Neil deGrasse Tyson tackling gravity. I can't be responsible for bad language (if there is any in this one)

Why do you need to know WHY.....

Like Neil Tyson said, there comes a point where if you keep asking "why" or "how" you run out of answers. We just don't know.

"A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole."

Good enough for me.

Gravity is not a force but a by-product of the curvature of space-time by a body with enough MASS to cause the deformation. Science can not seem to be able to resolve it much past that point.

Moving on.

There is no space-time...Einstein was wrong.

There is magnetism, dielectricity, and the Ether. Just ask Nicola Tesla.

Haha the Michelson–Morley experiment (1887) kinda put a nail in the coffin of the "Lumeniferous Ether" theory.

No, it didn't...its just been re-branded as the "Higgs Field". Haha back!

If after a 100 years or so, the greatest minds in physics can't unify Quantum Mechanics with General Relativity....then its time for a "re-think" of those two "theories", which is in fact, what they are..theories. They are getting hung up on epistemology rather than focusing on ontology.

Oh, and they can't seem to solve the "measurement problem" either.
