Starship Asterisk*

Is there an animation that would simulate/demonstrate the full life of a galaxy from formation to end? Would a possible end of a galaxy look like water flowing down a drain as its black hole devours it?

My science reading includes the physics and chemistry of the brain. In reading about the process that collects light energy bouncing around the universe, focuses it and delivers it to our brains via chemical and electrical signals makes me realize that the "images" of the universe we take ...

I just downloaded a book titled "The Alpha Torque" by Henry Cao which is a little to heavy in the math for me but brings up the intriguing proposition that a rotating universe might be the source for many unexplained phenomenon and physical measurements. It does seem intuitive to assume th...

Thanks so much Chris. I really appreciate your input and time. I just found the "Sixty Minutes" story on ALMA which filled in some visuals to your comments. http://www.cbsnews.com/news/alma-telescope-peering-into-universes-past/ I'm sure APOD will be passing on what those guys find. Holy c...

Oh geck! You're my kinda thinker. An animated photo GIF of infrared heat growing hotter and hotter until optical light pops on. It is strange however that such a common event has no greater description than dust collecting together. Thought Experiment: you are floating in a dusty nebula and suddenly...

By cross-section I mean a high-resol...
