Astronomers Repeat A Mistake

In the 19th Century several astronomers were convinced they observed canals on Mars.
Many people were told there are canals on Mars. This resulted in many entertaining science fiction novels about Mars and Martians, including a radio telecast and later movies.

Eventually, with better telescopes and later with space probes, no canals were found. This mistake by astronomers is just history.

Now astronomers are convinced they observed a black hole.
Many people were told there are many black holes in the universe. This resulted in many entertaining science fiction novels about black holes, and even movies.

Like with the canals on Mars. eventually people will realize the claims of observing a black hole were a mistake by astronomers. This recent event will become just history.
