Every other Wednesday we present a new video, so join us to see the truth laid bare...
Somewhere in our galaxy, at some time in the future, a spacecraft from Earth will encounter the most dangerous object in the Universe. A stunning visual journey into black holes, their structure and their creation.
A black hole is a geometrically defined region of spacetime exhibiting such strong gravitational effects that nothing, including particles and electromagnetic radiation such as light, can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
