The World is Not Enough: A New Theory of Parallel Universes is Proposed

Imagine if you were told that the world is simple and exactly as it seems, but that there is¬†an infinite number of worlds just like ours. They share the same space and time, and interact with each other. These worlds behave as Newton first envisioned, except that the slightest interactions of the infinite number create …

Einstein Right Again! Rapidly Spinning Pulsar Follows General Relativity

A unique and exotic laboratory about 6,800 light-years from Earth is helping Earth-based astronomers test Albert Einstein’s theory of general relativity in ways not possible until now. And the observations exactly match predictions from general relativity, say scientists in a paper to be published in the April 26 issue of the journal Science. Using ESO’s …
