Black and White
This last week, I’ve been reading about Black Holes. If you’ve seen the movie ‘Interstellar’, that involved a Black Hole that they were trying to avoid while skirting around the edges. Neil deGrasse Tyson applauded the science in that movie, so it’s educational as well as entertaining, right?
I’ve been reading science fiction for several decades, so I’m pretty well acquainted with what little is known about Black Holes. But theories grow and change, so I periodically read up on the subject, just to tweak my ‘knowledge’.
Most of what I read I already knew: Black Holes have so much gravity that nothing can escape once it’s entrapped, not even light, so they appear black. The gravity field of a Black Hole is so massive, that it even warps time, making it go slower. Black Holes are created when a star dies and collapses in on itself. And current theory is that there’s a super-Black Hole in the center of each galaxy.
But there were a couple things that made me pause and think. Such as the current theory that each Black Hole has a universe inside it. Therefore, this universe we live in must be inside a Black Hole. It makes me wonder what a Black Hole looks like from the other side. Where is the opening into our universe, and why haven’t we found it yet? How does that fit in with the theory of parallel universes? Are all the universes inside other Black Holes parallel universes to ours? Or am I trying to smash too much into one theory?
There was also the idea that since Black Holes exist, then there must be an opposite counterpart, a White Hole, where stuff would be spewing into our universe. Wow! And would a White Hole have negative gravity, the opposite of a Black Hole’s massive gravity? And would a White Hole spew lots of light and radiation, just like a Black Hole swallows up that stuff? Sounds like they’d be easy to spot. In fact, in my mind, a White Hole sounds like the other side of a Black Hole. So how come we haven’t found any? Well, just be patient. In 2006, an unusual burst of gamma radiation was detected, and currently being studied as a potential White Hole event.
And most of these facts and theories have been used in science fiction during the time I’ve been reading it. I can’t remember the name of the book(s), nor the author(s), but I can remember a scene or two that used each fact/theory. Except one. I don’t remember any books about Black Holes containing universes, but maybe I just didn’t get my hands on that one.
What about you? Read any good Black Hole books lately?
