# Thread: Is there an endpoint for Gravitational pull?

1. three thoughts that arrived in my mind.

A) Does an objects gravitational pull ever dimish to zero. Does my body exert a non-zero gravitational effect on Abell 1835?

B) Most energies diminish as the effects are used, a highly infrared object gets cooler as the heat energy is tranferred to another object, reducing the overall effect. Does the same happen with Gravity? I know the effects would be neigh unmeasurable, perhaps reducing from 9.81mps to 9.80mps over the next billion years, but does it happen? given enough time, will an object with a permenant mass, end up with zero gravitational pull

C) What is the smallest particle we know exerts gravity, Atoms do. but do Protons, Electrons and Neutrons? and if so, what about quarks and gluons? is there a point at which mass no longer exerts gravity?

No.

No, a body does not loose its ability to produce a gravitational force. Such a force is proportional to the mass of that body. So, unless matter is destroyed (e.g. via radioactive decay), the force does not change. Gravitation and temperature are completely different things. Temperature is the macroscopic representation of microscopic movements of individual particles.

All objects that have a mass or energy (they are equivalent) produce a gravitational force.

No, no energy is being used. But check out the Dirac Large Numbers Hypothesis, where he suggested that the force of gravity reduces over time. As it happens I think he was right, but it's something different to what you're suggesting.

5. The average kinetic energy of a body is always above zero, but what about a single particle. A single particle can never have zero gravity in that body.

But what about a single particle on it's own, yes it can have zero gravity.

6. No, it still has non-zero gravity, though there's nothing for it to gravitate with.

A-B. Does gravity radiate away from the center of mass? Radiate really isn't the word to use with gravity. The further you would get from the center of mass, the less gravity one would feel. Technically speaking, it never goes away, just gets infinitely smaller. Which means some rock on the other "side" of the universe is probably gravitating us right now. Just in an immeasurably small way.

C. Everything that has mass, will exert gravitation.
