The ocean world under the iceberg is actually a very terrifying world.
Biologists say: Strange creatures wrap another creature in bubbles and eat each other. Or use big pliers to cut each other off.
Fortunately we are behemoths and we do not follow their laws of survival.
Perhaps because the ocean is such a scary world, our ancestors escaped from the ocean, evolved into large creatures, and then experienced the beauty of the sea and ate seafood on a boat or on the beach.
Below the sea, they live in hell; above the sea, we live in heaven.
The physicist said: Neutrinos, trillions of neutrinos pass through me every second, and they have a huge amount of energy without interacting with our bodies.
At the beginning of the Big Bang, the universe consisted mostly of neutrinos. Neutrinos helped create this universe, galaxies, Earth, our civilization. To this day, they are also all the time in our weekly, flooded, sports.
However, they seem to be in another dimension, which we cannot see or touch, like a parallel ghost world.
Even if they accidentally show up, it's only 100 billionths of a second.
Medical scientists say: In our body, there are trillions of microbes. Quantitatively, these microbes outnumber the cells in our body.
To microbes, our bodies are like a small planet in which they thrive and evolve. Our bodies are like a spaceship in which they fight and die.
But we do not perceive their existence in huge numbers. Even as I write these words, I cannot sensibly believe that there are so many alien beings within me that do not fall under the stewardship of my physical empire.
They are like in a parallel space. Only when we occasionally go to the hospital for a physical examination, can we find their clues through some numbers: "Oh, I have Helicobacter pylori in my body, it's such an annoying little thing."
There is a huge gap between the micro and the macro. Intuitively, we cannot probe that world.
