Optics of the Event Horizon Telescope

Gravitational bending of light rays near objects of size approaching 2MG/c2 (gravitational radius or ‘event horizon’) is known to be severe.  Light rays circle indefinitely at 3MG/c2  as Charles Darwin (the grandson) described in 1958.  Gravitational lensing causes more distant … Continue reading

Hawking no comparison with Einstein

Good for Roger Penrose in standing up to the Hawking-cult (represented by Lisa Randall), when he said Hawking’s achievements were “astounding” given his physical condition. so lightly debunking claims he was the greatest physicist of our time, comparable with Einstein. … Continue reading

The Shell Collapsar established in GR

A consistent description is possible for gravitationally collapsed bodies in General Relativity, in which collapse stops before the object reaches its gravitational radius. Non-singular solutions exist with the density reaching a maximum close to the surface and then decreasing towards … Continue reading

Gravitational collapse without black holes

The contemporary notion of black holes originates in Oppenheimer and Snyder’s 1939 article “On Continued Gravitational Contraction” (Phys. Rev. 56:455, 1939).  Later Roger Penrose (Phys. Rev. Lett. 14:57, 1965)  showed that the O&S metric gave rise to trapped surfaces, ie. … Continue reading

Black Holes and whacky physics on BBC’s Horizon

The Horizon programme’s Who’s afraid of a big black hole (BBC2 16 Feb. and BBC4 19 Feb. 2012) shows how badly so-called ‘leading physicists’ have departed from solid analytical physics. This programme was a vehicle for physics-mystics; giving up on making their … Continue reading

Let’s dare to question quantum magic!

What a surprise from New Scientist’s editor.  Has caught on to the criticisms from a “small band of rebels” starting from Einstein, who point out quantum mechanics does not describe one of its central tenets, namely collapse of the wave … Continue reading

Can we celebrate Defeat for the Photon by Maxwell-Planck theory?

Success for SPUC and Maxwell-Planck theory is reported in Wikipedia as “experimental prediction of SED dubbed ‘spontaneous parametric up-conversion’ (SPUC) was tested in 2009 and 2010 with positive results.”   [consulted 1 Aug.2011] The formulations of both the Chinese (2009) and Indian (2010) … Continue reading
