Shameless, this guy on the first floor is really awesome. It took a lot of thought, hehe, I guess he found a place to copy it. . Let me explain briefly in words you can understand: there is twice as much water on the table, both of which are half. I poured them all into a cup, and the two halves of water became a cup, and they merged together; In addition, for example, glass, iron, steel, wood, etc. After melting, their liquids can also be fused together, as well as air and electricity. The vast majority of substances in the world can be combined to make them "shared", but only consciousness, that is, our thoughts, cannot produce common thinking, that is, collective consciousness, just like you never know what I am thinking, and my hand is hurt. .
