My understanding is that the most widely accepted theory of gravity shows that it is a product of mass, but doesn’t have mass itself. I could be mistaken though.
 
Gravitons, apparently, have infinite range, so they must, like photons, have zero resting mass. However, they do transmit energy in some form, so they would have mass from that energy. Still, because gravity is so weak compared to the other known fundamental forces, their mass would be minimal.

It’s rather like the quark-gluon field in a baryon: the gluons have color, and so are affected by gluons themselves, making the whole mess a sort of gluon soup, which is one reason the math is so hard to calculate.

BUT you could argue that the existence of gravity, and everything else in the universe, glorifies God, who made it. Not Catholic, but maybe theist. In a way. Not really…but it is more theist than atheist
 
I am not a Physicist, but from what I have read, gravity is caused by mass, but doesn’t have mass itself. Just like a radio wave doesn’t have mass.

However, it is still communicated somehow, at the speed of light.

For example, say Planet A and Planet B are 10 light-years apart.
The gravity of Planet A and Planet B act on each other.
If Planet B were to magically disappear, it would take ten years for Planet A to stop “feeling” the gravity of Planet B.

Or vice versa, if Planet A was alone and then Planet B magically appeared ten light-years away, it would take ten years for Planet A to detect the new gravitational source (Planet B.)

So something must be transmitting the gravitational “message” from point A to point B and vice versa. And that something, whether it be photons, muons, etc., must have some mass, no matter how infinitesimal.

That is just my two cents.

Scientists will probably discover an answer in a hundred years, well after we are gone.
 
Pax Christi!

The Mass has gravity. Or at least, today, it has solemnity.

I hope this confuses things a bit.

God bless.
 
Im learning so much that i never though id learn on this website.

Please forgive me: if I have understood, gravity does not have mass.

Is that correct?

THANKS!

Forgive my ignorance, how is gravity measured in pounds?

THANKS!

Well, say I was 150 pounds. That is because the gravity is pulling on me with 150 lb. of force. If you weighed more or less than that it is because gravity pulls you towards the center of the earth more or less than on me. This is because of mass. If i had a larger mass than you, gravity would pull on me more than you, and so i would weigh more. If i had less mass than you, gravity would pull on me less than you, and i would weigh less.
Please correct errors if i have any…

This is actually correct: Mass has gravity, but gravity doesn’t have mass.
 
In the ideas concerning the Big Bang, did that sole individual point have gravity?

If there is only one individual, how does its gravity effect no other beings?

THANKS!

Hmmmm. I’d say the singularity would have very high mass, so the gravity would be an intense field–but without distance to measure it, and before symmetry breaking differentiated it from the other forces, it would not matter.

Some speculate that, before (and in the instant of) the big bang, space was not yet expanded from one point, so there was no space, and no fields.
