Wavefunction collapse and gravity
If gravity can be thought of as both a wave (the gravitational wave, as predicted to exist by Albert Einstein and certain calculations) and a particle (the graviton), would it make sense to apply ...

What really is the future about the Standard Model
The fact that the bosons of the weak force have mass is something that I think technically poses many problems.
To avoid this and other problems with the masses of the particles devised a mechanism ...

Incompatibility Between Relativity and Quantum Mechanics
Why does Gravity distort space and time while the electromagnetic, strong, and weak forces do not?
Does this have to do with why Quantum Mechanics and Relativity are incompatible?

What kind of interactions denote 'observation'?
I'm quite perplexed by the notion of 'observation' in regards to the collapse of a particle's probability wave. Does a particle's wave only collapse when it is involved in a strong interaction (such ...

Quantum mechanical gravitational bound states
The quantum mechanics of Coloumb-force bound states of atomic nuclei and electrons lead to the extremely rich theory of molecules. In particular, I think the richness of the theory is related to the ...

The energy of a Graviton
Maybe another stupid question, but what's the energy of a graviton?
Is it $\hbar \omega$?
Does it emit gravitons when an apple falls onto the ground, like photons be emitted when an electron transits ...

Why is there a search for an exchange particle for gravity?
Here's a question on something I've been wondering about for quite some time. (I am not a physicist.)
If I understand correctly, according to Einstein's General Theory of Relativity, mass results in ...

Is Gravity an entropic force after all?
Recently, there was a rapid communication published in Phys.Rev.D (PRD 83, 021502), titled "Gravity is not an entropic force", that claimed that an experiment performed in 2002 with ultra cold ...

Particle wavefunction and gravity
Suppose a particle has 50% probability of being at location $A$, and 50% probability being at location $B$ (see double slit experiment). According to QM the particle is at both $A$ and $B$ at the same ...

Nature of gravity: gravitons, curvature of space-time or both?
General relativity tells us that what we perceive as gravity is curvature of space-time.
On the other hand (as I understand it) gravity can be understood as a force between objects which are ...
