I just can’t put my head around the fact that gravity isn’t just a force
EDIT : I now get how it gets stretched and how it’s comparable to putting a ball on a stretchy piece of fabric and everything but why is *gravity* comparable to that. I guess my new question is what is gravity ? 🙂 and how can weight affect it ?
In: Physics
So complicated… what if the way mass is attracted to mass (us, on this planet) and the way planets behave with each other (sun and earth) are 2 different things? What if the way the solar system works is not dissimilar to the way protons, neutrons and electrons work in an atom? Sometimes I wonder if we just haven’t invented instruments sensitive enough to measure variances in gravity like is gravity slightly stronger at the bottom of the Grand Canyon vs the top of Mt McKinley due to being just slightly closer to the core of the earth? I’ve tried to like the “push down” theory of gravity, but it just doesn’t explain how gravity increases as mass increases (earth vs moon). I have often wondered if gravity and magnetism are similar in some way we have yet to understand….
Think of space and time as the same thing.
Space is the dimensions of up and down, left and right, backwards and forwards.
Time is past to future.
So imagine all these dimensions. When something with mass is placed in spacetime it distorts it as spacetime wraps around it, the bigger the mass the greater the warp.
The sensation of weight is the distortion of spacetime as two things with mass are pushed together by the distortion (aka gravity).
The warping of time is just another effect of gravity.
