Although the desire to colonize Mars has yet to be fulfilled, the idea of living on Mars is still rich and varied.In the future, it's not out of the question that some humans actually settled on Mars, but most humans are probably still living on earth.The first group to live on Mars will surely have scientists, who will travel back and forth between Mars and earth for scientific research.So if some people, like scientists, return to earth after years of living on Mars, can they still live on earth as normal?
If humans can live on Mars, then the living environment on Mars should be similar to that on earth.This includes drinking water, food and energy for human needs.These are all things that humans can change and create, but there's one environmental condition that humans can't change: gravity on Mars.According to scientists, there is a big difference between the gravity of Mars and the earth.If the earth's gravity were one unit, the force on Mars would be only 10 percent of that on earth.
Because to settle on Mars, you have to adapt to the gravity environment there.So when the first man landed on Mars, he was sure to feel ethereal, and if he had lived in such a low-gravity environment for a long time, returning to earth after many years would have seemed out of place.Once you get used to the gravity environment there and go back to earth, you suddenly feel like your body has gained a lot of weight.Whether walking or resting, you will feel a person pressing on your body.
In addition, in a low-gravity environment, the human skeleton will become loose.So after returning to earth, the bones are under extra pressure, and a little bit of carelessness can lead to fractures.In addition to the bones will not adapt to the earth's environment, the human body's physical and chemical environment such as blood pressure will not adapt.So it's best to stay there once you've migrated to Mars, to avoid the extremes of the body.Some scientists even think that once humans have adapted to the environment of Mars, they will gradually evolve into another species.
