What if you’re somebody’s shadow?

Two days ago, I discussed several theories which call for universes parallel to our own. Brian Greene, writing in Discover Magazine, floats another one even queerer than the three I mentioned. Whereas the other worlds in my last post were causally isolated from our own, this hypothesis posits that all the events in our universe are [...]

Inflationary multiverse theory may have recieved first direct empirical evidence

Democritus, or perhaps Leucippus, was the first Western thinker to propose an infinite universe. Many of Democritus’ commentators in early Greek philosophy, most notably Aristotle, found the hypothesis extravagant. However, numerous strands of 20th century physics suggest Democritus not have gone far enough, and advance a succession of theories positing an infinite number of universes. Quantum [...]

Some hobbyists collect stamps; others probe the very heart of matter

To each their own. Via the Washington Post:  A Swedish man who was arrested after trying to split atoms in his kitchen said Wednesday he was only doing it as a hobby. Richard Handl told The Associated Press that he had the radioactive elements radium, americium and uranium in his apartment in southern Sweden when [...]

After the Standard Model?

The Standard Model (SM) is the current best theory for the explanation of subatomic particles. It yeilds some of the most accurate and precise predictions of any mathematical-physical theory, but is still problematic and incomplete.  Apparently, to those whose eyes are trained to recognize mathematical aesthetics, the SM’s equations are contrived and fugly, whereas most great physics equations are elegant in their [...]

NZ physicists mathematically describe quantum entanglement in time

Via PhysOrg: In “ordinary” quantum entanglement, two particles possess properties that are inherently linked with each other, even though the particles may be spatially separated by a large distance. Now, physicists S. Jay Olson and Timothy C. Ralph from the University of Queensland have shown that it’s possible to create entanglement between regions of spacetime [...]
