Israel snub comes from great scientist

The superb articles by John Haylett (M Star May 11) and Ramzy Baroud (M Star May 14) are indeed right to point out the significance of Professor Stephen Hawking's snub to Israel. Hawking is one of the most illustrious physicists alive. In 1973, long before ... [Published Morning Star Online - May 17 2013]

Hole in one

Your look at the black hole firewall paradox described Hawking radiation as the escape of one of a pair of virtual particles that pop into existence at the event horizon while the other falls into the black hole (6 April, p 38). So how does this Hawking ... [Published New Scientist - Apr 24 2013]

How can we see black holes? [Starts With A Bang]

All Physicists know that Hawking Radiation Violates the Infinite-infalling-time Theorem

“The particle takes an infinite time to reach the critical radius r = 2m” (as Lucasian Professor Paul Dirac wrote on page 33 of his book “General Theory of Relativity” of 1975). So the twin particle of a pair fluctuation cannot reach the critical radius ... [Published Lifeboat News The Blog - Dec 18 2012]

Recently though, a second fundamental time’s arrow was found in nature. ... [Published Lifeboat News The Blog - Dec 15 2012]

Hawking radiation: pure and thermal mixed states are a micron away

Quotes

"The situation is that he's discussed it with fellow academics and has decided, for personal reasons, not to attend the conference in June" a University of Cambridge spokesman said, as quoted by the BBC

Cosmologist Stephen Hawking Boycotts Israeli Conference [Published LiveScience.com - May 08 2013]

...arguing that quantum mechanical radiation, analogous to the Hawking radiation that appears at the event horizon of black holes, would show up and "inevitably lead to [the warp bubble's] destabilization whenever superluminal speeds are attained."

Faster-Than-Light Drive [Published Popular Science - Apr 01 2013]

We learn that "We thus conclude [something]". That's nice that they "conclude" something except that "something doesn't follow from the previous sentences and it isn't even well-defined. In principle, the evolution of any degrees of freedom in a black hole spacetime may depend on any other degrees of freedom – there is room for some nonlocality – except that we must always ask how strong the nonlocality is, how it can be parameterized, whether it may be operationally measured, what variables may parameterically suppress it, and so on."
