If Mars can be inhabited, can people on earth talk to people on Mars?

If Mars can be inhabited by people, you can talk to people on earth by telephone, but you must meet certain conditions and meet the following points.

First, the base station should be built on Mars, which can only be covered by signals, because Mars is much bigger than the earth, and signals can't cover all places.

Second: There must be multiple signal turning points between Mars and the Earth, because the distance between the two planets is too far, and it cannot be directly transmitted to the Earth without a transit.

Third, there needs to be a huge signal base station on the earth, which can transmit to the moon.

In fact, although Mars may be suitable for human habitation, it is also a theory. Humans have never landed on Mars, learned from other sources, and found no water or oxygen.

If one day humans immigrate to Mars, the indigenous people on the earth want to make a phone call with people on Mars, and the phone bill is also very expensive, which most people may not be able to afford.

The current communication mode is impossible, and it will become possible when we find a communication mode that exceeds 1 100 million times the speed of light. Because it takes us dozens of minutes to hear each other's answers when we say a word, and we can only say a few words in 24 hours. Especially if the leader of our unit is on a business trip on Mars and suddenly thinks of holding a video conference, our Spring Festival holiday will be ruined. This meeting may last for a year, and everyone should eat, drink and sleep in the conference room.

There will be a moment when Mars will overtake the sun this year. At present, Mars is also approaching the earth, so this year is considered to be an excellent year for Mars exploration. China, the United States, Europe, Russia and other space agencies have Mars exploration programs. In the future, mankind will usher in a "fire exploration" period.

The purpose of exploring Mars is to land on Mars and immigrate to Mars in the future. At that time, humans can build a closed base on the surface of Mars, where they can simulate the ecological environment on the surface of the earth and live as if they were on the surface of the earth. However, at this time, if humans on Mars communicate with humans on Earth, there will be a delay problem, because Mars is too far away from the Earth.

Mars is less than 55 million kilometers away from the earth at the nearest time and nearly 400 million kilometers away at the farthest time. Even if the communication signal is transmitted at a speed of 300,000 kilometers per second, it will take a long time. In a word on Mars, it takes 183.3 seconds for radio transmission to reach Earth. In other words, it will take more than three minutes for the earth people to hear what the Martians just said. If you are at the farthest distance, the radio signal needs to travel 1333.3 seconds to arrive, which means it takes 22.2 minutes to hear people from Mars, which is obviously very inconvenient.

Is there any way to solve this problem? This may require the use of quantum entanglement. Quantum entanglement is a physical phenomenon that occurs purely in a quantum system. In a quantum system, elementary particles have certain * * *. For example, if two elementary particles belong to a quantum system, changing the state of one particle will also change the state of the other particle.

Take two electrons in opposite directions but at the same speed as an example. Even if they span the entire solar system, they will remain related. When the state of one electron changes, the state of another electron changes almost simultaneously. This is the quantum entanglement phenomenon. Obviously, transmitting some information in this way saves a lot of time than transmitting information by light and radio, because if the speed of light crosses Neptune's circular orbit, it takes 500 minutes, about 8.3 minutes.

At present, it is impossible to tell how fast quantum entanglement can be, how effective it can be, or even how effective it can be. It is generally believed that in the quantum world, when several particles interact, because the characteristics of each particle have been integrated into a whole, it is impossible to describe the properties of a single particle alone, but only the properties of the whole system, so each particle can only describe the properties of the whole system.

When this tangled technology matures, after human beings immigrate to Mars, the communication between Mars and the Earth will no longer be a problem, and it should also be possible to make instant calls and videos.

According to the present way of mastering science and technology, it is impossible to communicate with Mars by telephone. Because the most important feature of telephone is real-time communication and dialogue. However, according to the distance from the Earth to Mars, it takes several minutes for electromagnetic waves to reach each other. In other words, it takes a few minutes for one party to say a word, and it takes a few minutes for the other party to say a word. Therefore, real-time communication is completely impossible, that is, telephone communication cannot be realized. But it is no problem to transmit information in one direction, including voice, image and data, which can be transmitted between two planets.

Yes, the basic principle of telephone is electromagnetic wave. Theoretically, as long as your telephone signal is strong enough, you can talk to people anywhere on earth except black holes. The question is, how long will it take you to say a word and get a reply? On Mars, it will take your friends on earth about ten minutes to hear and reply to you. If you are in the Vega department, it will take about 50 years. Therefore, it is unrealistic to make real-time calls on Mars. The best way is to send WeChat voice messages and wait for others to reply. You can also read books, water flowers and pass the time while waiting.

You can't talk until someone answers the phone on Mars! Don't worry, it will come one day.

Answer: Yes!

(1) According to the current level of science and technology, it is possible to make a call, but only if both sides of the call need to be patient enough to wait every time they say a word ... [covering their faces]

(2) According to the future level of science and technology, that is, Mars can be transformed/suitable for human habitation, then it is even more important to realize the call ... [giggle]

can

It is impossible to live on Mars. As long as the earth people reach the surface of Mars in less than two seconds, they will spit out their internal organs. The questioner was cheated by the Martian boy, right? Haha, that's a scam.

With the development of science and technology, it should be no problem to call!
