Re: UCLA: Moon Was Produced by Head-on Collision
Pindar praises Theia in his Fifth Isthmian ode [say that 5 times fast - ACN]: Thanks Art. Now I'll be able to sleep tonight. :wink: After assimilating that Fifth Isthmian Ode I might tackle Hesiod's Theogony - "to organize a narrative to tell how they came to be and how they established perman...

Re: APOD: A Candidate for the Biggest Boom Yet... (2016 Jan 26)
Zeno's paradox really doesn't work with black hole evaporation because when the hole gets half as small it's radius decreases at a rate four times as fast (i.e., eight times as fast relative to it's size). Radioactive material is only half as radioactive after a half life and would, in fact, (Zeno-...

Re: APOD: A Candidate for the Biggest Boom Yet... (2016 Jan 26)
I'm too lazy to look it up now, but I'm sure Hawking said that the bigger a black hole is, the longer it takes for it to annihilate itself. For a black hole of a few million solar masses, we are certainly talking about trillions of years. And since the universe is only ~14 billion years, the chance...

Be careful who you let babysit your kids. Though he probably deserved an Oscar. Is that spaghettification or pancakeification in practice? Looks closer to mushification.

I couldn't figure out why our helium supply seemed -all of a sudden- better. It's not like we are going to start making it helium from fusion any time soon.
Then I read this.
But then again maybe there's a new source?
Those Canucks are ambitious!!
