Explores one of the deepest mysteries about the origin of our universe. "According to standard theory, the early moments of the universe were marked by the explosive contact between subatomic particles of opposite charge.
Scientists are now foc...using their most powerful technologies on an effort to figure out exactly what happened. Our understanding of cosmic history hangs on the question: how did matter as we know it survive? And what happened to its birth twin, its opposite, a mysterious substance known as antimatter?"

Este video explica la teoría del Big Bang. Según esta teoría, el universo comenzó con una violenta y cegadora explosión que lanzó todo al caos. Desde entonces, nuestros grandes pensadores han tratado de estudiar ese caos para buscar el orden, la lógi...ca y las respuestas al interrogante de nuestro origen. (1:30)

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.).

In this History Channel video clip on Lemaitre, we learn a lot about the scientist and a bit about the theory on the Big Bang. With the help of some Einstein theories, Lemaitre conceived a theory of his own that may have proved to be right. This vide...o is a discussion of George Lemaitre's theory about the Big Bang. Run time 04:30.
