gives you a bunch of spherical magnets of the same size, please let them attract each other and be uniform in direction. This may sound simple, but it is not. When the same sex repulses and the opposite sex attracts each other, magnets always have positive and negative poles. It is too difficult to attract each other evenly in all directions. Let’s take a look at the closest magnet beads, Batter magnet balls, Bucky balls.
This is so neatly stacked because it is directional and cannot attract each other without distinction.
idea determines the way out, change the same-sex repulsion, the opposite-sex attractions to same-sex attractions, and the opposite-sex repulsion, and then make the magnet ball shell the same polarity and make the other polarity inside, and the problem is solved.
Assuming that this magnet ball does not take up space, then, in a purely mathematical sense, a magical scene will occur, two magnet balls approach each other and then stop. However, when the center of the magnet ball crosses the spherical surface of the opponent's magnet ball, the two magnet balls smash together violently, completely tightly fitting and unable to separate. In other words, it is combined into one.
This is impossible, because attracting and repulsing each other in the opposite sex is contrary to the laws of the earth. However, there is indeed a natural phenomenon that is homosexual attraction. That is gravity.
The closer the gravity, the greater the force. If it is infinitely close, then isn’t the gravity infinitely greater? This is really a very good question. Going back to the above thinking, the entire universe will be firmly attracted together.
This is impossible. According to the law of universal gravitation, will gravity be infinite when two objects are infinitely close? First of all, macroscopic objects do not. Take the earth as an example, the surface of the earth has the greatest gravity.
followed by microscopic objects are not infinitely large, because there are new interaction forces that obscur our measurements. Electromagnetic forces, strong interactions, weak interactions and other forces cover the truth. However, considering the three words "infinite" size, gravity will definitely come from behind and eventually dominate. This requires two protons to be accelerated to the speed of light and collided to simulate it.
Open the brain, gravity is actually the positive electrode and the interaction is the negative electrode. So, according to the previous simulation, it can be said that it is understandable.
