That’s the beauty of the earth being round. Every point on the circumference of the earth is the “top”. It did take a long time to figure out gravity. Many had a name for the force before Newton. Aristotle had an idea all the way back to antiquity. Newton figured out the how...but not the why of gravity. It’s took until 1915 and Einstein to provide the why.
I still don't get the HOW.
It's called a gravitational FIELD; but, does it have any SPEED; like Light?
We can block light, but putting something in between to attracting bodies does...
...what??
