What is the mechanism by which gravity “pulls”? Puzzling me for almost 10 years. I think I’ve almost got it.
Hehe guess what… Nobody exactly knows how gravity works.
So let’s start with Newton. According to his equations, gravity is a force. Why? Well, according to the first law of motion, an object stays in motion in its original direction till a force is applied on it. Newton said, “Gravity is clearly actively changing the direction of an object. Hence, gravity is a force”. As Newton establishes that gravity is a force, we say that it “pulls” objects. However, he couldn’t explain the mechanism behind this pulling force.
Then came Einstein. According to general relativity, gravity is not a force. How’s that possible? Doesn’t gravity change the motion of a given object? Nope! Wait, whaaaaa?! Okay, so according to special relativity, all things in the universe are on a “spacetime”. What’s a spacetime? Well, it’s a four dimensional fabric like thingey that all objects are present on. The four dimensions are time and the three spatial dimensions that we experience. Mathematically, there is no difference between time and the spatial dimensions. However, all objects move only in one direction through spacetime at c, ie., lightspeed through spacetime. If an object moves at c through space, it moves at 0 m/s through time and vice versa. This is how you get the time dilation magic. Cool. Now what if we bent this said spacetime at certain points? The object traveling on this spacetime would be traveling in a straight line always. Hence, no force. Hence, no pulling. Hence, no pulling mechanism.
Cool! So we solved gravity, right? Sike! GR doesn’t work at the quantum level… Aaaaand most of the best models that we have for quantum gravity use a particle called the “graviton”, which has a field that results in an attractive force. How does this force work? The answer is “go fk urself”.
Hence, in conclusion, noone knows whether gravity even “pulls” in the first place, let alone HOW it pulls. Aaaaand we’ve been trying to answer this question for almost 100 years… Cool…
tee hee hee - guess what. I didn’t ask for quantification and prior art.
I wouldn’t say nobody, but I would say the people that dominate the area I’m trying to volunteer and work in.
I work in a healing center where there are 29 women on staff and 1 man.
I cannot get these people to understand that as much as they want to push forward social movements, which I very much agree with, this must not come at the expense of men who are trying to heal.
I will literally have counselors co-facilitating with me, who want to make every point about how women are oppressed, pushed down in the workforce, face issues.
I’m not in denial of those, but no man coming into a healing environment to work on themselves, be vulnerable, and explore their own journey, needs to hear how much men are shitty.
Exactly. You can see this on various aspects of life. Racism, sexism, etc. Many use them as excuse to throw out the baby with the bath water.
