It’s our inclination to think that things everywhere are like they are where we are.
Gravity is like that. It is everywhere. Consequently, we think of gravity as a powerful force that keeps us glued to the ground and brings down huge airplanes. Actually, science tells us that gravity is a very weak force. In fact, it is the weakest fundamental force we know of in the universe.
To prove this to yourself, go to a children’s toy shop and buy one of those little 50-cent horseshoe magnets. Then put a paper clip on the ground. Place the magnet near the paper clip. You now have two competing forces — the electro-magnetic force of the little magnet versus the gravitational force of the entire Earth. The magnet wins. The electro-magnetic force is actually 1,000,000,000,000,000,000,000,000,000,000,000,000 times stronger than gravity.
But because gravity is all around us, we think of it as a strong force.
The same is true of the internet. Most advertising and marketing people have come to believe that because the internet has become pervasive in our lives, it must be a strong advertising force. So far it has not been.
