Are there really aliens What are they like which of you has ever seen

Haven't seen it. But I believe there is.

There are billions of planets in the universe, and there will always be life on one of them. No matter what form or pattern it takes, there will always be life.

We don't have a comprehensive enough exploration of the world as we already know it. Although we went to the sky, we did not leave the galaxy; went down to the ground, and did not go more than a kilometer underground; When I entered the sea, I didn't know what 10,000 miles under the sea were. We don't even have a full understanding of the earth we live in, and we don't have enough knowledge of the outside world, so we can't say that we are the only one.

Maybe Earth is still the plaything of a higher creature—a joke.

There are about 400 billion stars in the Milky Way. One out of every ten such stars has a planet. In each of these groups of planets, there may be one similar to the Earth at a distance from the Sun, not too hot and not too cold.

Let's imagine that one out of every ten planets supports life. Perhaps only one in a hundred of such planets can evolve intelligent life. If only 1 in 10 of these planets had developed technology to communicate with distant places, then we would have the opportunity to make contact with millions of civilizations.

We should remember that the Earth is 3.5 billion years old since the beginning of life, and that it has only been 50 years since it was able to communicate through interstellar space, and how many of the four million possible civilizations are in the process of evolution like us? Despite all the uncertainties, at least the opportunities for us to come into contact with intelligent life beyond our own galaxy are endless.

If there is a high probability that there will be other life in the universe, why is there no other civilized world to come into contact with us? Maybe it's been a long time ago, but we haven't been able to receive information so far. Improving our own technology may be able to listen to the messages of our galactic neighbors.

At three p.m. on October 12, 1992, some 500 years after Christopher Columbus arrived in the New World, NASA scientists flicked a button in Puerto Rico and California, beginning a new era of scientific exploration.

No rocket blasted through the atmosphere. However, some of the world's most powerful radio stations and telescopes are listening for extraterrestrial signals. The mission of the microwave observation program for extraterrestrial intelligence exploration is to scan the entire universe for signals of intelligent life.

Two types of searches will be piloted, with the world's largest radio telescope near Arecibo, Puerto Rico"Targeted search"。It will focus on 800 to 1,000 sun-like stars located within 100 light-years of the Earth's orbit.

More broadly"Space surrounding"The remaining 99% of the space is to be examined, and anything unusual is to be heard. The search will be conducted through a radio station antenna on NASA's deep space network in the Mohagan Desert in California. The information received from both sources will be processed by advanced computers.

The Alien Intelligence Exploration Program is designed for listening only. But we sent information into the universe years ago. Early experiments were to transmit radio waves, television waves, and laser signals into deep space.

But there is still the question of how can aliens understand us? Scientists try to express it in a meaningful way"Greetings from Earth! "

Yes. Earth is just one living planet in the Milky Way, and there are many things in the Milky Way that we currently don't know scientifically.

Besides, the Milky Way is just an ordinary galaxy in the entire universe, so there will be no more life on countless planets?

Obviously impossible, it's just that the current level of science in our human race cannot reach a higher level.

So firmly believe that there are aliens!

There are many examples of aliens in the world, mostly through hypnosis to make people who have encountered it recall that memory, of course I haven't seen it, hehe, don't believe that there are aliens in yourself.

Yes, but this generation doesn't want to see it. Aliens put aside the next generation to watch.

Extraterrestrials may exist, but modern astronomical observations have ruled out the possibility of extraterrestrials in the solar system. Outside the space, which is light-year-long, it is a distant distance that is difficult for us humans to conquer! Therefore, the huge distance in space seems to have become an insurmountable obstacle to the interconnection of intelligent beings, so even if there are aliens, it is difficult for us to find out, let alone know that they live in**.

So we don't know anything about the aliens, let alone what kind of flying machines they use. You can imagine that even the speed of light of 300,000 kilometers per second would have to travel for years, decades, hundreds, tens of millions of years, or even longer! What an unimaginably long distance!

Therefore, it is simply impossible for the so-called aliens to visit or invade the earth! Constrained by the laws of physics, it is hard for me to believe that intelligent beings can build spacecraft that can fly at the speed of light, which is all science fantasy, how can it be so easy? Therefore, it is not credible.

Taking a step back, even if intelligent beings were capable of building superspacecraft that could travel at or beyond the speed of light, it would be impossible to move freely in the vast interstellar space measured in light years. I am pessimistic about this, and I believe that human beings may only be able to exist alone forever in the universe!

It can be said that so far there is no credible evidence that aliens have visited our earth, and all rumors about aliens visiting earth are not credible. Therefore, I can tell you with certainty that no one has ever seen aliens with their own eyes, and that there is no scientific basis for what aliens look like.

The preference, the appearance of real aliens, may always be a mystery to us.

I've seen it up close, but it's not a movie saucer, it's a rocket
