High School Is Gravity an entropic property like Surface Tension

[marees]

Why do two separately floating objects in a liquid "attract" each other ??

What if gravity is an emergent property like surface tension ?

What if they both are essentially trying to *minimize disorder at the interfaces — where non-aligned polarized particles are forced to mix with each other*

What if gravity is an emergent property that is trying to optimize the entropy emerging out of spin aligned quantum bits

 

[Rob Trajon]

I think gravity may be so hard to define because it's not created/carried by a particle. It's a consequence of something else (mass, or perhaps also momentum). Like a shadow or reflexion of something else. It's a "byproduct", not an original force in it's own right.

Well, it is. What we obseve as gravity is simply the physcial manifestation of the curvature of spacetime.

Objects in freefall follow a geodesic - the shortest path through curved spacetime. Around massive objects, where curvature is high, this causes them to appear to curve toward each other, when in fact, they are simply following this shortest-path geodesic.
