Why was October 1582 missing 10 days and what happened then? Where did those 10 days go?
"An inch of time is worth an inch of gold, an inch of gold can't buy an inch of time" - "Zengguang Xianwen, Part 1" Time is the most ruthless thing. It will not stop or even go backwards because of people's subjective wishes. It will only flow forward. For everything dominated by time, human beings seem to be active, but in fact they are passive. They can only watch their skin gradually darken, their muscles atrophy, and their body functions decline until they die. Why was October 1582 missing 10 days and what happened then? Where did those 10 days go?

The universe is constantly expanding. In what kind of space is it expanding? Inseparable from the universe is not fast enough
On the earth, most people may not care how big the universe is, because the size of the universe seems to have nothing to do with them, because for them, the earth is already big enough, and it is too big to walk in a lifetime. Finish. Even so, human beings still look up at the deep space under the guidance of their dreams, and this look is really surprising. The universe is too big. The earth where humans live is located in the solar system, and this star system with a radius of one light year is definitely an insurmountable space for today's human beings, although we can launch some spacecraft like "travelers", Let them fly aimlessly out of the solar system, but it definitely can't be regarded as leaving the solar system in the true sense.

Voyager 2, which is 20 billion kilometers away from the earth, sends back signals in the so-called "space"?
On August 20, 1977, NASA's Voyager 2 probe was sent for liftoff on its ascent to the solar system. After traveling 4.1 billion light-years, Voyager 2 reached the limit of the solar system's heliosphere, the tail end of the solar wind, in November 2018. Since then, Voyager 2 has entered interstellar space, where cosmic radiation is stronger than that of the sun.

Martian settlers seek death? Scientific exploration has repeatedly hit a wall, and behind it is a difficult problem that cannot be explained by science!
There are countless planets in the vast universe, but there are not many planets known to human beings. Mars should be the most popular one besides Earth, because Mars and Earth have very similar characteristics, so people call Mars the twin brother of Earth. It is precisely because of similar characteristics that for a long time, humans have been the best choice for Mars for space immigration. However, in the later exploration process, scientists found that it was not as easy as they imagined, which also troubled scientists for a time. Martian immigration is really suitable ?
