With the development of science and technology, the depth and breadth of human exploration of the universe has become larger and larger. The universe hundreds of millions of billions or even tens of billions of light-years away, with extremely weak information, shows us mysterious and mysterious complex world. However, the problem of the scale of the universe has always been a bottleneck restricting direct human detection. The distant universes we see through space telescopes are actually their historical images, unless we can observe them up close.

If there are only 1 male and 1 female left on the earth, how long will it take to multiply to 7.6 billion people? The answer is cruel

Once the population growth rate slows down, effective countermeasures must be taken and the focus will begin to shift. If we remain indifferent, the consequences will be disastrous. India is the representative.
