Dark Matter/Dark Energy

I was watching "AFI's 100 years, 100 songs" last night. However, during commercial, I flipped through the channels and ended up watching "Scientific American Frontiers" on PBS and forgot about the "100 songs". The show was about the dark matter and dark energy of the universe. Very weird stuff. It's kinda mind-bloggling that most of the universe is composed of the matter we do not know and cannot see. Can dark matter form "dark stars", "dark planets" and even "dark life"? Maybe somewhere in the universe some "dark people" are wondering the same question. Also, if, as they claimed in the show, dark matter is everywhere in the universe, is it in the normal world? Is it an integrated part of the "normal matter"? Is it in us?

I always like this kind of cosmos weird stuff. In a book I have read before, the author not only discussed the dark mater and dark energy, but also the superstring, multiple dimensions of the universe (16 dimensions, if I remembered correctly), "mirror universe", multiverse, and, weirdest of all, multiple time axes!

Wow! Our universe is just getting weirder and weirder!

Oh, BTW, the host of that show, Alan Alda, is soooo funny! He is at least 50 years old and still behaves like a child! At one time of the show, the astronomers who were conducting a very important experiment to search for supernovae kindly invited Alan to sit in front of the main control computer for a test drive. He rolled his chair in position, and, with an excited mischievous boy's expression on his face, he rubbed his hands above the keyboard, exclaiming:"I'm gonnna strike some keys!" The scared astronomers cried out:"NO, NO, NO!" He asked:"What should I do then?" They said:"When that guy says 'ok', you hit the 'return' key." He was kind of disappointed:"That's it?" The astronomers replied firmly:"That is it!"

From now on, I'm gonna watch more "Scientific American Frontiers".
