Scientists have discovered the smallest and closest black hole, only 1500 light-years away, will it affect us?
Black holes are arguably one of the most amazing and elusive celestial bodies in the universe so far. From the perspective of the characteristics, formation process and influence of black holes, scientists divide the black holes in the universe into three types, namely, the central black holes of galaxies, the collapsed black holes of massive stars, and the tiny primordial black holes generated at the moment of the Big Bang. In recent decades, astronomers have used various monitoring methods to discover many large black holes at the centers of galaxies, as well as medium-sized black holes formed after the collapse of massive stars at the end of their lives. However, the question of just how small a black hole can be has been a mystery in astrophysics.

There may be evil civilizations in the universe. If aliens are found, human beings may be enslaved or even destroyed!
Are we humans alone in the universe? Probably not, but that's not the only answer to the questions astronomers are seeking to relate to aliens. While many scientists do their best to reach out to or at least find alien civilizations, others ask key questions: Are we sure we're ready for aliens to find us? If alien life is found, do we try to contact it or make it disappear? Some people think that aliens might not be a threat to us humans, while others have dire thoughts.

What are black holes, white holes and wormholes? Which is the strangest?
The most common way of reproduction in nature is sexual reproduction, that is, the reproductive cells of both sexes combine to develop into a new individual. This method has many advantages. For example, sexual reproduction can promote the spread of favorable genetic mutations within the population, speed up the evolution of species, and enhance the ability of individuals to adapt to the environment, which is of great benefit to the survival of species. Sometimes, some scientists may do the opposite, using sexual reproduction to reduce the population size of some species.

There may be an alien civilization! 4.2 light-years away from humans, civilization is more than 60 years behind humans
There is no end to the exploration of space. In the universe, besides humans, are there any other alien intelligent creatures? There is no answer to this question for the time being. If there are aliens in the universe, or if human beings come into contact with aliens, it will prove that there is still a home suitable for life in the universe. The lifespan of the earth is nearly five billion years, and the sun will also be near It will end in five billion years. Although this time span seems to be far away for now, it also means a serious problem. If human beings do not find another suitable place to live in the universe, human civilization will one day disappear. To disappear without a trace.

An interesting paradox in the scientific world: as long as the turtle runs first, no matter how much people chase it
In the race, as long as the tortoise starts before the human, how can the human not catch up with the tortoise? Does this theory sound outrageous? In our understanding, how can the human not catch up with the slow speed of the tortoise? ? Just like a white horse is not a horse, we all know in our hearts that it is not the same thing, but after listening to the theory, we can't find a way to fight back.

Some scientists not only do not have a holiday, but are also ready to tell you a discovery of "10 years of sharpening a sword"
As we all know, the Labor Day holiday should be more labor (obviously not). Scientists are even more familiar with this principle, and they have found a large-scale er who advocates "studying more seriously during holidays", and talk to you about the discovery of "hardening a sword in ten years".
