Oxygen or the speed of light, which is the root of all evil that locks humanity on earth?

Have you noticed that when we stay in a room with locked doors and windows, after ten minutes, we will feel difficult to breathe, if you don't open the window at this time, there may be a serious problem of suffocation? So why is this happening? Actually, it's all because we need air, or to be precise, we need oxygen.

All plants and animals need to breathe oxygen, and if the earth suddenly loses oxygen at some point, a large number of organisms may die, so oxygen is also a necessary factor for the existence of life. But many people may not know that in fact, oxygen did not exist on the earth in the past, and it was only later that something happened that caused oxygen to appear, and since then it has been out of control and has become a major element on which all life depends.

According to the research data of scientists, the appearance of oxygen on the earth began 2.4 billion years ago, and then, after evolution, in the period of 300 million years ago, its content reached the highest peak in history, that is, 35%, because of this reason, the earth's organisms have become larger, and the ancestors of modern dragonflies were several meters long at that time, which can be called behemoths. However, the first life on Earth was not 2.4 billion years ago, but much earlier.

That is, 3.4 billion years ago, plants and some organisms had appeared at that time, but life at that time did not need oxygen, nor did it produce oxygen, and even photosynthetic plants did not produce oxygen at that time. But for some reason, in this short period of 1 billion years, the earth has undergone great changes, you know, it is because of the emergence of oxygen that our modern life can not survive without it.

Therefore, scientists have always been very curious about the reasons, and some experts even believe that the emergence of this oxygen may be produced by extraterrestrial civilizations, and its purpose is to better limit human development. Just imagine, if we humans can survive without oxygen, then we can move to an alien planet without worry, and at the same time, we can be relaxed when diving into the deep sea.

But because of the emergence of oxygen, we are constrained everywhere, and long-term breathing of oxygen is extremely harmful to the organs in the body, because of this reason, human beings cannot live long, so it is not impossible to say that this is used by extraterrestrial civilizations to limit the development of human beings.

Oxygen and the speed of light, in fact, oxygen is the root of all evil that locks human beings on the earth, because oxygen is only found on the earth, and cannot be found on other stars.

I think oxygen is the root of all evil that locks humans to the earth, because humans can't live without oxygen.

According to the research data of scientists, the emergence of oxygen on the earth was first 2.4 billion years ago, when some simple plants and organisms had appeared, and plants would produce oxygen when they photosynthesize. Gradually, a large number of plants appeared, and slowly there was oxygen in the air. Nowadays, people and plants and animals are inseparable from oxygen, and it can be said that oxygen is the root of all evil that locks people to the earth.

Actually, neither. We believe that after the slow development of science, neither of these will become a shackle for human exploration of space. At present, there is no way to explore space on a large scale.

Or because the scientific and technological conditions are not up to standard, there is no way to ensure the long-term self-sufficiency of human beings in outer space.

Oxygen is a substance necessary for human survival, and there is no oxygen that humans can breathe directly except for the earth in space. While oxygen is important in space exploration, humans can overcome it. The universe is so big, in order to reach farther places, humans must have faster speed, so the speed of light is the culprit that locks humans to Earth.

Oxygen is the culprit that locks humans to Earth. Because humans need oxygen to survive, and oxygen is only available on earth.

Oxygen. Because only the Earth has suitable oxygen, and other planets have almost no oxygen, oxygen is the culprit that locks humans to Earth.

Yes, because human survival is inseparable from oxygen, but outside of the earth, oxygen is scarce.

I can't figure out why human beings have to get their physical bodies outside the earth, the earth and even the entire solar system is a huge spaceship, with human beings running wild in the galaxy and even the universe, therefore, there is really no need to get the physical body outside, with the rapid development of artificial intelligence, AI can completely bring human consciousness outside the earth, and observe and understand the outside world!

Yes. If humans don't have oxygen, they can't continue to live, and that's the biggest problem.

Now humans themselves can produce oxygen, vines, greenery, and weeds on alien planets. Can you grow grass in the desert?
