speed of light, 300,000 kilometers per second, which is indeed very fast. But no matter how fast it is, the speed of light is limited after all, and the limited speed of light also determines that everything we see is actually their past, and what we see is the scene that has happened in the past.
This is easy to understand. For example, we often say, "The sun we see is the sun 8 minutes ago", and so on, the Jupiter we see is actually the Jupiter 30 minutes ago.
Most of the twinkling stars in the starry sky are stars from decades ago or even millions of years ago. Perhaps those stars have disappeared long ago, but we have to wait millions of years to see them disappear.
Although we see all the scenes of the past, they are real scenes of existence after all. However, some scientists have put forward an incredible point: the real world we live in is not real, but virtual, just like the game world simulated by computers.
I believe many people have watched the science fiction movie "The Matrix". The movie describes the virtual world that subverts our traditional thinking, believing that the human brain is not a sensing system that accepts various virtual signals, but that the brain itself is virtual.
The entire universe is like a supercomputer simulated, which is so powerful that it can simulate everything in the universe, including everything we see, hear, and feel.
Some people may question, the universe is so big, with trillions of celestial bodies inside, how can a supercomputer accurately simulate such a huge amount of information?
Anyone who has played online games should understand this. Computers do not need to simulate all scenes. They only need to simulate the scenes where the characters pass by. Other scenes will be blurred and will be accurately rendered when the characters of the game pass through certain scenes. Doing so can greatly save the computer's computing power.
Perhaps a super cosmic civilization can create such a powerful computer and use the above-mentioned "cheating" method to simulate our universe. The method of
also makes sense in theory. Just look at today's human technology and you will understand.
Now Artificial intelligence and computer technology are booming, and computer performance has been greatly improved. Scientists can use computers to simulate more and more real scenes, such as what happened in the moment of the Big Bang, and can use computers to simulate it.
Although the simulated scenes are different from the real scenes, theoretically with the improvement of computer performance, humans will definitely be able to simulate a simulation environment exactly the same as the real world, and even simulate the entire solar system and the entire universe!
If this is true, how should humans affirm that the universe we are in is not simulated by a more advanced cosmic civilization?
