What does Hawking mean by his warning? What did Hawking's warning say

For human beings, the exploration of alien civilization is first of all a kind of curiosity, because it is human nature. Human beings are always trying to uncover their mystery. Is aliens really there? Why does Hawking repeatedly warn humans? What does Hawking's warning mean? What did Hawking warn of?

Hawking is a famous physicist in the world. He once expressed his views on the extraterrestrial creatures in the universe. Mr. Hawking once said: 'I am more firm than ever, we are not alone'. But Hawking warns humans not to try to contact aliens. They are more terrible than they think. He means that human beings should stop contacting with the outside world. He believes that if contact is likely to expose us, it will put human beings in an extremely dangerous situation.

But since we explored the universe, we have sent signals to all parts of the universe many times, which means our position has been exposed. Hawking also said that if this happens, we may be attacked by aliens at any time. Hawking thought that aliens may live in a huge spacecraft. These advanced creatures will fly around, look for a possible life planet, and then turn the planet into their own territory.

Hawking concluded that if humans try to get in touch with aliens, the risk factor is too great. If one day the aliens arrive at the earth, the end of mankind will be like Columbus landing on the American continent, facing great disaster. However, it still can't stop people from exploring the universe and alien civilization, and even many people are looking forward to meeting with aliens.

We have been trying to get in touch with alien civilizations for a long time. We bombard space with electric waves, which now cover thousands of star systems. Even we can imagine that intelligent life on a certain planet may now be able to turn on the radio and listen to some popular songs on earth. But this is just a hypothesis, because the chance for two civilizations to meet is too small. Even if we receive the signal from the alien civilization, but because the space is extremely far away, it is difficult to know whether the alien civilization talking with the earth exists in this period.

So in general, it's Hawking's saying: 'don't try to contact aliens, they are far more terrible than you think! '
