Theoretically are all particles subject to gravity. Or is there any particle which need not be affected by gravity.
Does that mean gravitons attract all other particles?izh-21251 said:All objects that have energy do interact gravitationally... Since E=sqrt(m^2+p^2), there are no observable particles with 0 energy. So all particles (including massless) are subject to gravity.
If gravitons exist (we don't know), they would have self-interactions. I would not call this "gravitons attract all other particles", however, and this is a tiny effect. Gravitons (again, if they exist) mainly transmit the gravitational interaction between other objects.officialmanojsh said:Does that mean gravitons attract all other particles?
Ok. Gravitons are exceptional particles which are said to be those who create (functioning) gravity But I can't agree completely to you. Because as you said particles subject to gravity, it means particles are subjected to gravitons, right?mfb said:If gravitons exist (we don't know), they would have self-interactions.

vanhees71 said:Usually what's meant when somebody talks about "mass-energy" it's the rest energy of a body, ##E_0=m c^2##, where ##m## is the invariant mass of the body, but it's the full energy-momentum tensor coupling to the gravitational field in the Einstein-Hilbert action and not only the parts from the mass terms in the Lagrangian.
Yes, all particles with mass are subject to the force of gravity. This includes subatomic particles like protons, neutrons, and electrons, as well as larger particles like atoms and molecules.
Gravity is a force that pulls objects with mass towards each other. In the case of particles, gravity causes them to attract and pull towards each other. This is what keeps planets in orbit around a star, and electrons in orbit around an atom's nucleus.
No, all particles with mass are subject to gravity. However, the force of gravity is very weak for smaller particles like subatomic particles, which is why we don't typically see the effects of gravity on a microscale.
Gravity cannot be blocked or shielded like other forces such as electromagnetism. However, the effects of gravity can be counteracted by other forces, such as centrifugal force for objects in orbit around a larger body.
Yes, the force of gravity is the same for all particles with mass, regardless of their size or composition. However, the strength of gravity can vary depending on the mass and distance between particles.
