Let me help you here. You seem to ridicule Newton's gravitational definition. What is that definition?
In a nutshell, it's that mass attracts mass. I don't ridicule it, I simply question the reason as to how it supposedly comes about, which is an unknown force called gravity.
After all this time, it's unknown.
It's unknown for a reason, which is....it's an easy way of hiding what it really is, which allows it to be used in fictional space exploits and to describe observations of space.
Actually here it is.
"the principle that two particles attract each other with forces directly proportional to the product of their masses divided by the square of the distance between them."
Notice how obviously incomplete this definition is? It simply describes gravity as a force but it makes no attempt at explaining what the mechanisms are. This is actually not incompatible with your definition of gravity where you use phenomena like pressure and magnets.
Do you see why it is ridiculous to ridicule this? Newton isn't making any claims about what gravity is at all here. His definition is basically the same as saying "things fall" followed by some mathematically true statements about just how fast those things fall. If those things are falling because of pressure and magnetism then great, what Newton says here doesn't contradict that.
Now, if you look into another thread where you and I are discussing pressure you'll see that pressure and magnets don't seem to have any correlation to whatever is causing gravity. There is no evidence to support this.
Moving on in history, Einstein came up with General Relativity and that theory actually does try to give a cause to whatever gravity is. We can go on from here but I already know you have difficulty with the concept of spacetime.
Here's what you are saying.
Newton is the man who thought up gravity but didn't know what it was, as he explained it far too basically, as in, things fall due to mass/weight and a force that he does not know, acts upon this mass against mass.
His name is constantly used, but Einstein TRIED to make sense of it and came up with his dolly mixture bags of relativities, each time a problem arose.
Now you are telling me that I have difficulty getting to grips with space time.
I don't have any difficulty at all, it's 100% clear to me, it's just that you cannot accept that, because you believe you understand it and yet I'm basically telling you it's a load of crap and is simply made up like a lot of it is, to cater for what we are told happens up there.
Yes, I know I'm going to be labelled ignorant and uneducated and that's fine, but no matter what you say, you still cannot stake your life on what you have read into as being TRUE...it has to stay theoretical.
