NASA at Reddit AMA says Earth is unlikely to be eaten by a black hole

Everyone loves black holes. They are strange and mysterious, and we all went crazy when we saw the first image of a black hole in April . NASA's black hole experts took to Reddit on Friday to ask questions about these mysterious objects.

There is a lot of fascinating information in the discussion, but the best news is that a black hole is not likely to breathe our planet.

NASA research astronomer Varujan Gordjian took the lead in answering a question that asked how likely our planet would be absorbed by a black hole. "It's not very likely at all. Space is very large and the probability of a black hole passing near us is extremely unlikely, especially since black holes themselves are rare objects," Gordian wrote.

Wait a minute … passing us by? Yes. Some black holes can move.

"Indeed, the massive black holes in the galaxy centers will remain there unless something catastrophic happens, such as a direct collision between two galaxies," the NASA Chandra website shares in 201

1. "The much smaller black holes formed by the explosions of stars can move relatively quickly because they get a kick out of the explosion. "

NASA released a fun black hole safety video this week that covers the basics of these astronomical objects. Reddit Q&A delves into more detailed scientific discussions. They both come to the same conclusion:

You "will probably be crushed at an infinitesimal point," McGill University physicist Daryl Haggard writes on Reddit.

It's a good thing we don't expect a black hole to come anywhere near the Earth. However, asteroids are another matter .
