Is it true that humans can't imagine something they haven't seen?

Human thinking is limited by cognition, and the so-called imaginative science fiction in Europe and the United States is only holding a laser sword to cut each other. It wasn't until "The Three-Body Problem" sacrificed water droplets and two-way foil that people understood that there was still this way of destruction.

Twenty years ago, DVDs were like the world of science fiction. When television was first popularized, some children ran behind the TV to find the villain.

Because the car the child was sitting in had automatically upgraded windows, he had never seen a hand-shaken window, so he didn't understand what "shaking" was. As a child, watching others make plexiglass tabletops. I found it amazing that the craftsman poured water on the tabletop and then formed a transparent plexiglass. It wasn't until I studied chemistry that I realized that it was just the process by which a liquid turned into a solid.

I've always suspected that dinosaurs weren't what they are at all, because no one had ever seen a dinosaur, but only imagined them through their bones. It's like this weird-looking lion. How to look like a dog.

Science fiction is also limited by the times. Verne fantasized about going to the moon, relying on cannons. Orbiting the earth for 80 days depends on hot air balloons. He had no idea that the current satellite would circle the Earth in a few hours.

It turns out that the mobile phone in science fiction is a phone booth. I think I've seen a sci-fi video phone, which is a TV set next to the telephone, and when I make a call, a portrait of the TV Li appears.

If the bench has such sharp thorns, can you still sit? Now Europe and the United States are more advanced, with different design protrusions, which make you uncomfortable lying and sitting. Now there is such a thing in the country.

When I was a child, I heard people say that American artillery can run, and when you shoot a shot, you can jump to another place, which I think is very amazing. When I grew up, I saw self-propelled guns and understood what was going on.
