‹ Saturated Absorption Spectroscopy •
A few weeks ago I noticed an article that appeared on physorg.com, which is a great resource of everything science related, titled, “Black Holes Made of Light.” A few weeks ago I glossed over this article as it seems there are always papers published where a physicist has stopped light or in fact reversed it. However, this article was brought to my attention again: Scientists at the University of St Andrews have used lasers to simulate a black hole in their laboratory.
Why aren’t you dead?
It would seem logical that since I am living at St. Andrews I should have been consumed weeks ago by the intense gravitational pull of the black hole which resides in the vary building which one of the researchers, Dr. Friedrich König, lectures me every week about spatial and temporal coherence of light waves. Luckily, the “black hole” and white hole are merely simulated as an event horizon. So, I’m still alive and you don’t have to worry about the rest of the earth being swallowed. Check out the article–it presents a number of basic concepts about event horizons, so it’s a good read for beginners. I’ll have to ask my lecturer about his work tomorrow.
