Light Speed image

Light Speed

According to the laws of physics we can never travel faster than the speed of light...or can we? Light speed allows us to see things instantly here on Earth, and shows us the entire history of the universe going back nearly 14 billion years. Learn all about light speed, the ultimate constant in the universe and discover ways scientists envision breaking the "light barrier" which may be the only way the star travel of our imaginations ever comes to reality.

Black Holes & Beyond image

Black Holes & Beyond

The universe is a strange and violent place, full of regions spewing out energy on an unimaginable scale and objects so massive not even light can escape from them. With the discovery of quasars (extremely luminous, compact objects in the hearts of ancient galaxies), the picture of the universe became more complex. Though the mechanism responsible for such enormous outputs of energy is not completely established, one answer was found in a part of Einstein’s theory of relativity — black holes, specifically supermassive black holes at the centers of distant galaxies. These objects consume enormous amounts of matter. As the matter falls inward, it releases a large amount of observable energy. Einstein didn’t think black holes were possible, despite the fact that his own theory implied their existence. Robert Oppenheimer thought otherwise and set out to prove the presence of collapsed stars so massive not even light can escape them. Black holes seem to be a reality.
