well, i had my last 2 root canals done today. that made 7 total. wow. next up will be an appointment with the ortho - not scheduled yet.
so i was reading cnn and saw an article on astronomers finding a supernova that was first spotted in 185 A.D. made me think - hmm, what's the time frame on a supernova? is that an instantaneous implosion/explosion, or is the whole process more gradual? is it measured in seconds, minutes, months, years? went to wikipedia and started reading about supernovae, but then got sidetracked to novae, then the milky way galaxy, then the andromeda galaxy, the local group, the canes venatici cloud, the virgo supercluster, the galactic core, barred spiral galaxies, and of course, the universe itself.
estimated 200 - 400 billion stars in the milky way galaxy.
estimated 1,000 billion stars in the andromeda galaxy.
and of course, there's like billions and billions of other galaxies out there containing billions and billions more stars and possible solar systems.
meanwhile, we get to worry about terrorism, fanatacism and untold other -isms instead of putting more effort into learning more about what's around us. Whatever.

Yep, the problem with all those -isms is that when someone latches on to one, it usually leads to them believe that they ALREADY know everything there is to know. No use poking around for more information when I've got all the answers, right? And any challenge to that knowledge is a dangerous thing.
You know, it's kind of ironic, but I don't have a lot of tolerance for intolerant people.
