Astronomia: Uma Visão Geral II - Aula 14 - Matéria Escura

Astronomy: An Overview II - Lecture 14 - Dark Matter First identified in 1933 by Swiss astronomer Fritz Zwicky, dark matter remains one of the main challenges facing contemporary science. As Professor João Steiner, from the Institute of Astronomy, Geophysics, and Atmospheric Sciences at USP, explains, the bulk of the Universe's mass is of a nature we still don't understand. Dark matter is not baryonic, has no electric charge, has no magnetic field, and does not emit light. The only known property of dark matter is gravity. In this lecture, Professor Steiner discusses how dark matter was discovered and the evidence that supports the existence of a matter whose nature is unknown, but which may be up to 20 times more abundant in the Universe than baryonic matter.
