I was listening to NPR on the way home and a general science teacher (junior high, I’d assume) was relating an anecdote about something that happened in her class. She was discussing the difference between fact and theory with the students. She explained that while it is a fact that the galaxies are moving away from each other (Edwin Hubble’s discovery), it is only a theory that there are black holes. Why? We can see the galaxies’ motion but we cannot see black holes and therefore can not claim them as factual.

She couldn’t have been further from the truth. The Hubble site (also linked on right) documents the analysis of numerous images of phenomena none other than black holes. Below are three links:

Ancient Black Hole Speeds Through Sun's Galactic Neighborhood, Devouring Companion Star
Black Holes Shed Light on Galaxy Formation
Hubble Discovers Black Holes in Unexpected Places

I don’t know what she’s teaching, but it ain’t science. Maybe weird science.
