Uh. Hey dude... ya'know like.... You dropped 99% of your universe back there... See?

Cool! They just finished building a massive super collider to attempt to generate some dark matter and other weird particles but slamming two galaxies together is a WAY more massive super collision. :)

Of course, I'm also presently listening to a story about a microscopic black hole so the timing is kind of neat and cool too. :)

It doesn't need to be infinitely massive to work like a black hole. Just nearly infinitely massive.

Measuring them is usually done by mass which relates to the event horizon ('visible' size) because the more massive they are, the broader the area known as the event horizon is.

But what it means... Well, gravity is a two-way force. A microscopic black hole would put out microgravity. You put out nanonano gravity. Someone might not even notice it.
