The Earth's atmosphere is constantly losing
Kardashev RatingOf the eight planets in our solar system, Mars is the closest to Earth in terms of the natural environment, so it has rightly become a key exploration target for humans, who have launched many probes to Mars in the past and have harvested a large amount of Mars data.

The unsolved mystery that has plagued scientists for 200 years
I'm sure we all have the experience of riding a bicycle. The structure of a bicycle is very simple, frame, tires, pedals, chain, brakes, all these things are reasonably assembled enough to keep us balanced during the riding process. But have you ever thought about why a bicycle can be balanced during a ride instead of falling over?

For humans 500 years ago, the strength of modern humans can be said to be the crushing level of existence, so if someone asks, if a civilization found in the solar system 500 years behind the human race, how should humans respond?

The earth is spinning slower and slower
On a cosmic scale, the Earth not only rotates around the Sun at all times but also rotates itself at all times. Rotation brings many natural phenomena to human beings on Earth: day and night, deflection of horizontal movement of objects, the difference in local time by one hour every 15 degrees of longitude, and so on.

The average temperature of the universe is only -270.42°C
There are a huge number of stars in the universe, each of which can be considered a hot "ball of fire" that emits a lot of light and heat into the cosmic space every moment. It is easy to think that the universe as a whole should be warm, but this is not the case, because according to scientists' estimates, the average temperature of the universe is only -270.42°C.
