How did Voyager 1, which is 22.8 billion kilometers away, send the signal back to Earth?
The universe is so big, but the range of human activities is very small. So far, the farthest place humans have been to is the moon, and the average distance between the moon and the earth is only 380,000 kilometers. Of course, humans have also launched a variety of detectors. If you count them, then the range of human activities will be much larger.

How did the gorillas in Africa spread AIDS to the locals and then to the world?
The disease of AIDS is not terrible, because its transmission route is relatively single, through blood transmission, sexual contact transmission and vertical mother-to-child transmission.

However, AIDS is still spreading on a large scale among human beings, and so far there is no cure.
