Here's what would happen to you if you encountered a small black hole

The idiocy that got me was the babbling about the huge explosion 3 times Hiroshima/Nagasaki. That works out to about 150 kilotons.

Pretty small potatoes compared to say, Novaya Zemlya, and that rather large blast was insignificant on a stellar scale.

The tines the power of Hiroshima would devastate a good portion of the earth? Got it. This is obviously real physics.

You've got to keep the Luddites and the low information crowd scared of science and atomic energy, you know. . . exaggeration and always, always invoke Hiroshima and Nagasaki. Bugaboos. Short circuits logic every time in what laughingly passes for their minds.

Oddly, the density of a black hole is inversely proportional to the square of its mass; a black hole with the mass of the universe would be about the size of the universe.

Would it’s gravitational force be inversely proportionate as well?

If so why couldn’t the theory be made that the Universe is a giant black hole, and Dark Matter, and Dark Energy are the by-products, or building blocks if you like.

We know what happens at the entrance to the black hole, but not what the interior is.

If this is too dumb a question please chide accordingly. As you can obviously tell, I am not an Astrophysicist.

I am not an astrophysicist, either. Your questions are generally provocative and intelligent, and I do not have solid answers. I don’t want to confuse you with speculation. What ever little I know about anything, I learned by persistent and open minded inquiry. Good luck.

Thank you sir. You are a gentleman, and a scholar!

More like: 40 to 50 kilotons.

But yes: Still small potatoes!

Sorry, each bomb dropped on Japan had a yield of about 12 - 15 kt. So three times the COMBINED explosive yield (as cited in the article) would approach 100 kt.
