explain gravity. not with equations, just explain how it works and why it works

pic unrelated

Gravitons.

Matter is attracted to other matter.

The foam that makes space-time get's curved by mass, the more mass you have the more curvature there is.

This. This is the fact of gravity.

Our best THEORY of gravity at the moment is that this is because any energy density, of which matter is the most dense form we know, causes spacetime to bend around it. Then the trajectories of moving objects are bent as well. This is general relativity.

>> No.3620703

>>3620692
So is the energy that we're bending also keeping us in place?

OP, that's like saying describe poetry without language or describe the working of a computer without going into code. It's difficult to do without using its respective language. It can be done but not as elaborate and concise.

>> No.3620707

>>3620703
It's the space that is bent. Matter, or any energy density, bends spacetime.

>>3620692
Well then how would that relate to a smaller scale, such as with people. Sounds good when dealing with massive interstellar masses, but not so much on the smaller level of things

i don't think you understand the gravity of the situation, OP

>>3620706
What I meant by that is, don't just give me the equation of gravity. I have a paper to write over what exactly is gravity. Not the equation of gravity, or what it does, just what is gravity. I realize its impossible question right now, but I just wanna get some ideas that are out there

It works out fine when you do the math.

But for casual everyday use, we use classical Newtonian gravity. It's easier to calculate, and almost as good for use near an Earth-size mass.

How old are you?

>>3620715
Honestly, our current answer to that question is incomplete. The best we can give you is the rough meaning of gravity in general relativity, but we know that our picture of "what is gravity" is incomplete.

Read some of Einstein and Newton's papers. It should help.

>> No.3620731

>>3620719
Don't forget: Gravity hardly matters at all on the smaller scale. It's about as weak as a force gets.
(Even the Weak force is orders of magnitude stronger on the scales where it's relevant)

>> No.3621425

>>3620715
It's a mystery, period. The most you can say about it without going hypothetical is that it is a inexhaustible force only capable of attraction.
