NASA | Computer Model Shows a Disk Galaxy's Life History

This cosmological simulation follows the development of a single disk galaxy over about 13.5 billion years, from shortly after the Big Bang to the present time. Colors indicate old stars (red), young stars (white and bright blue) and the distribution of gas density (pale blue); the view is 300,000 light-years across. The simulation ran on the Pleiades supercomputer at NASA's Ames Research Center in Moffett Field, Calif., and required about 1 million CPU hours. It assumes a universe dominated by dark energy and dark matter. Credit: F. Governato and T. Quinn (Univ. of Washington), A. Brooks (Univ. of Wisconsin, Madison), and J. Wadsley (McMaster Univ.).

I made a video where I looked through an astronomy book from the 1930's and highlighted some of the more amusing assumptions and embelishments which were made based on the data of the time. While astronomers at this time had accepted that the sun was part of the Milky Way this conclusion hadn't really filtered down to the general population.

Yes, check my channel - watch ?v=wc5zJBLXPAE

Since religion and science are mutually exclusive camps according to many, isn't it ironic that the one who proposed the Theory of the Big Bang was a Belgian Monk, Georges Lemaitre?

why no music??

[Gabriel Müller]

How can the sun move relative to it?

[Sarcazims]

the sun does move idiot... ever so slightly, keeping everything in balance

Sir Isaac Newton would have a raging brainer after watching this.

из-за химических реакций взрыв произошел

прикольно

[Xeinzul]

Хорошо, как не из-за чего, просто вот так, может произайти взрыв?
