On the road to exploring the universe, aliens are always an inevitable topic. In a sense, the process of human exploration of the universe is actually the process of finding aliens.
Humans have been looking for aliens for decades, but no effective clues have been found so far, and the sky is still so quiet. The result of
is not surprising. The universe is too big, and the earth is so small in comparison. The distance between celestial bodies is so far, even the speed of light seems as slow as a snail.
The distance between celestial bodies is often thousands of light years. Even if it is a distance of 100 light years, it takes 100 years for the electromagnetic wave signal to arrive. If an alien receives a human signal, it will take another 100 years for the transmitted signal to arrive on Earth, and this will take 200 years for a round trip.
200, humans and the earth have probably changed dramatically, and people have long forgotten the signals they sent 200 years ago.
However, the above may be just wishful thinking of humans. Why do we require aliens to use electromagnetic wave signals? Perhaps, for advanced alien civilizations, they have long abandoned the "backward" information transmission method of electromagnetic waves, and they use more advanced information transmission methods, such as using the black hole itself.
For black holes, time loses its meaning, and time is no longer a problem. All the laws of nature we know have failed in front of black holes, which means that black holes have strange characteristics that we cannot imagine. Many things that we think are impossible are sparse and ordinary for black holes.
At least from a mathematical analysis, using the characteristics of black holes, people can travel time, get rid of the constraints of time and space, and instantly cross the vast interstellar distance.
To put it bluntly, it is to travel interstellarly in the form of " super-light speed " to spread information. Perhaps this is the reason why humans have not discovered aliens so far: we were wrong in finding the direction of aliens at the beginning. In this way, there will be no result.
Will there be such a high-level alien civilization in the universe?
exists in theory and is very likely. Think about it, the age of the earth is about 4.5 billion years old, while the age of the Milky Way is over 10 billion years old, and the age of human beings is only one million years old. In theory, it is very likely that a high-level alien civilization with a history of civilization of hundreds of millions of years is a high probability. Can you imagine how high a high-level cosmic civilization with a history of civilization of hundreds of millions of years will reach?
No matter what, humans will not stop looking for aliens. We also long for some advanced alien civilization to discover humans and establish connections with each other. Although there are many uncertainties and even unpredictable consequences, curiosity will drive humans to continue to move towards deep space!
