The only honest answer is that no one knows.

Whatever force causes gravity is the same force that will cause the Nobel people to give you $1,000,000.00. If you can answer the first force one correctly, the second force will be automatic.
Who ever answers that question, (with definitive proof via an experiment of goodness knows what kind) will sit next to Einstein, Newton, Galileo and a very select few others for a very long time.

Nobody really knows. One idea was that the Higgs boson couples quarks to spacetime to cause the curvature that we call gravity. Another idea was that there would be a "graviton" particle mediating gravity. Neither of those has quite panned out.
String theory seems to have a built-in connection between spacetime curvature and mass on a quantum level. More of a starting assumption than something derived like GR. Be my guest trying to figure out what causes gravity from that.
When you figure it out, you'll be rich and famous.

If you want an answer to that, you would have to keep an eye on the Nobel prize winners for the next few decades, because right now nobody knows what exactly causes gravity.

You know there is a magnetism force between the north and south poles right? The magnets attract and cause pressure. Gravity (in a scientific way ) is that pressure.

Gravity is a force that acts upon this universe from outside of it. It is the force responsible for the existence of the universe.

I always thought it was the mass of the earth spinning and the magnetism of the heavy metals in the molten core that made gravity on earth

the revolving nature of our solar system in the source of gravity on the earth and principly the sun...........in principle it's related to the core density of the sun and the effect this has..........suggest you read a basic astronomy book..........far too much info for a quick answer. But in short there is no definitive answer that can be quantified. All theories.

All massive objects "bend" the space around them (no one knows why) -- this bending causes the trajectory of other objects to curve in response. What we call "gravity" is the observation of this bending effect.

The distortion of space/time by mass. Imagine a bowling ball sitting on a sheet of elastic, bit like that but with an extra dimension.

Universal force of attraction acting on all . More is the mass more is the force
