P1120019 Discussion of cosmology: the first black holes
The first black holes -- a slide from Science Cafe, a lecture / discussion on cosmology organized by Center For Inquiry Austin, and lead by a Ph.D. student in astrophysics.
"The first black holes were probably about 30-100 the mass of the Sun. Within about 1 billion years, some of them managed to grow to 1,000,000 the mass of the Sun, and perhaps more."
Here is my blog post on what happens when a skeptic's sense of wonder meets scientific reality, based on this lecture.
