Anyway, the force of gravity keeps everything on earth from floating off into space. If gravitational forces suddenly ceased and everyone started to float away, it would make it, among other things, very difficult to get to work on time. Although that might not be the first thing that pops into anyone’s mind while drifting into the sub-zero temperatures of the stratosphere.
Scientists tell us that gravity on earth is essentially constant. There are actually some barely perceptible variations, and if you ever have trouble falling asleep at night, just read the detailed explanations in a science journal.
Even though most scientists say that gravity on earth is constant, I have discovered that the scientists are missing something very important. The force of gravity increases as we get older.
Just look at the faces and bodies of elderly people. Everything is sagging. Why? Because gravity is much stronger for these people.
What is a major worry for old folks? Falling down. And why do seniors fall so often? Too much gravity.
While astronauts can hit a golf ball 500 yards on the moon, I can’t even hit a drive 180 anymore, while I used to hit my tee shots around 250 (never straight, though). What changed? Obviously my personal gravity has gotten much stronger with age.
The original equation for gravity was determined by Sir Isaac Newton, who declared:
That is, the gravitational force between two bodies is equal to the mass of the first body times the mass of the second body, times a gravitational constant; all divided by the distance between the two bodies squared. If you understand any of that, then you paid attention in physics class — something I did not. I may be baffled by the formula for gravity, but I do know how to cut and paste from a website.
So, don’t take gravity for granted (or granite). We need gravity to keep us from floating off into space. But be aware, as you get older, gravity gets stronger. I don’t have detailed scientific data to back up my claim, just a lot of real world experience.
