PBS program got number of stars wrong?
On a program on PBS-station KQED (9) in San Francisco by Daniel Amen Clinics
"Change your brain, change your life" he made the claim that there are 100 billion cells in your brain, more than all the stars in the whole Universe. It was my understanding that our own galaxy has already appx. 500 million stars, surely more than 100 billion, and there are hundreds of billions of *galaxies* in the visible Universe. Who is correct, Daniel or Robert? |

Who is correct, Daniel or Robert? The number of stars in the Milky Way Galaxy is of the order of 100 billion, perhaps double that or more, due to the uncertain large number of low mass stars. I think Kippenhahn's book on astronomy of stars and the galaxy was titled "A Hundred Billion Stars" in English. -- Mike Dworetsky (Remove pants sp*mbl*ck to reply) |

Oops, I must have been tired when I posted, that I made a stupid
typo and didn't notice it until today: From: (Robert Maas, see http://tinyurl.com/uh3t) On a program on PBS-station KQED (9) in San Francisco by Daniel Amen Clinics "Change your brain, change your life" he made the claim that there are 100 billion cells in your brain, more than all the stars in the whole Universe. It was my understanding that our own galaxy has already appx. 500 [m]illion (should read) ................................... 500 [b]illion stars, surely more than 100 billion, and there are hundreds of billions of *galaxies* in the visible Universe. Who is correct, Daniel or Robert? Addenda, the 500 billion estimate might include brown dwarfs, I don't know. I seem to recall estimates of 100 billion stars many years ago, upped to 500 billion stars recently, but I'm not sure. |
