If something is inbetween two objects how do the particles know there is something bigger behind the object it needs to attract to?

Why is it every time I visit this sub, nobody knows how to simplify it to honor the sub’s name?

It’s not a complete definition of gravity, but it’ll help you understand.
Well, depends on what you mean by blocked or dampened.
Let’s look at heat here. Heat, just like gravity, is type of energy. It behaves a bit differently when it comes to exact science, but for our purposes it works fine.
How do we dampen or stop heat? We put something between heat source and what we want to stop from getting heated up. Heat dissapear? No, it gets absorbed into the material we used as a heat shield. Same with removing heat from object. We coat it in something that has low heat and well tranfers heat itself like water. The heat dissapears, it’s just divided between more matter, so original matter has less of it.
Similarly is with gravity. We can damper it by putting a force between two object that attract themself by gravity. That’s how we achieve flight. We create enough force to stop gravity. Like heat before, gravity doesn’t dissapear, it just is counteracted.
The only major difference is that we cannot really stop creation of gravity like we can put out the fire. Cause fire is a chemical reaction that generates heat. We can stop that reaction. But gravity is generated by existance of matter itself. And removing matter from existance is way harder.
But to shortly answer your question: we can damper gravity. That’s what wings and engines on planes do. That’s what you do for a short moment when you jump. Or even when you just stand. Your legs damper gravity enough so you aren’t crushed into the earth beneath you. There’s just a lot of gravity created non-stop.
I feel like a lot of the answers are presenting great theories, that are ultimately unproven and largely are just describing how we know things act.
The truth is, we don’t fucking know. We just don’t know a lot about gravity, what it ‘is’ and how it functions.
We know it has a pulling force, it acts broadly based on size of object. And there’s theories it fits nicely into for equations and working things out by maths.
But there’s a whole lot more we don’t know about gravity…yet…
If someone in this reddit really knows why, he would get a nobel prize.
We know less about gravity than most people think.
People can explain how it works but not why.
