But inwhen scientists were examining spectra of different stars, they found that some of the characteristic lines of the star spectrum was shifted towards the red end of the spectrum. Meine kurze Geschichte englischer Originaltitel: But in astronomy and in some other situations, regularities were observed. Finally, Roger Penrose used light cones and general Relativity and proved that a collapsing star could result in a region of zero size and infinite density and curvature called Black Holeso Hawking and Penrose proved together that the universe should’ve arisen from singularity which Hawking himself disproved once Quantum effects are taken into accounts.

Print Hardcover and Paperback. We never observe it working in the opposite direction. Our subjective sense det time seems to flow in one direction, which is why we remember the past and not the future.

Aristotle also thought that the sun and stars went around the Earth in perfect circles, because of “mystical reasons”.

InErrol Morris directed a documentary film about Hawking, but although they share a title, the film is a biographical study of Hawking, and not a filmed version of the book.

This idea seemed strange at first, but many people accepted it after a while. When black holes suck in other stars, the black hole lets out X-rayswhich can be seen by telescopes. Twin paradoxa part theory of Relativity which explains that two twins can age differently if they move at relatively different speeds or even at different places where spacetime curvature is different.

Views Read Edit View history. Early inHawking first approached Simon Mittonthe editor in charge of astronomy books at Cambridge University Presswith his ideas for a popular book on cosmology. Black holes are difficult to find because they do not let out any light. The stars are very far away from us, so we only observe their one characteristic feature, their light. Weak nuclear forces are the forces that cause radioactivityor when matter emits energy.
