Gravity is, you know, the force that pulls you toward the center of earth especially hard when you are standing on the scales. Some people think that gravity is one of the strongest forces in the universe. Wrong! I will have to agree that gravity is what keeps the planets in place around our sun and which control a large percentage of the universe, but I will give you an example of why it is not the strongest force. Take refrigerator magnets for example. They stick to the refrigerator door and can also hold paper or other stuff up with them. I have seen magnets with small hooks to hang towels, etc. on and they all seem to overcome gravity and stay in position. In fact of the four forces, gravity, electromagnetism, the weak nuclear force, and the strong nuclear force gravity is the weakling. No one yet has discovered what really causes gravity. Once it can be completely understood, then maybe they can come up with "anti-gravity". That will help out when you step on the scales, and a minor advantage would be an anti-gravity device to power your flying saucer.
Another thing I wonder about is the origin of words and phrases. Gravity's first meaning was something weighty or serious originating from the Latin word "gravis" meaning heavy. All the things in the formula for gravity on the top line are divided by the distance squared. That means that an object twice as far away has only a quarter of the gravitational force. So any object light years away has very, very little force acting on us, but as infinitesimal as it is, it is still there although we may not be able to detect it. Now, the next time you step on a scales you can think about how gravity affects not only you but everything, and I mean, everything. Now, you all have a great day today and stay off the scales, you hear?
