Penrose claims LIGO noise is evidence for Cyclic Cosmology
19 July 2017 | 3:48 pm

Noise is the physicists’ biggest enemy. Unless you are a theorist whose pet idea masquerades as noise. Then you are best friends with noise. Like Roger Penrose. Correlated "noise" in LIGO gravitational wave signals: an implication of Conformal Cyclic Cosmology Roger Penrose arXiv:1707.04169 [gr-qc] Roger Penrose made his name with the Penrose-Hawking theorems and twistor theory. He is also

Nature magazine publishes comment on quantum gravity phenomenology, demonstrates failure of editorial oversight
13 July 2017 | 11:17 am

I have a headache andblame Nature magazine for it. For about 15 years, I have worked on quantum gravity phenomenology, which means I study ways to experimentally test the quantum properties of space and time. Since 2007, my research area has its own conference series, “Experimental Search for Quantum Gravity,” which took place most recently September 2016 in Frankfurt, Germany. Extrapolating

Stephen Hawking’s 75th Birthday Conference: Impressions
9 July 2017 | 11:09 am

I’m back from Cambridge, where I attended the conference “Gravity and Black Holes” in honor of Stephen Hawking’s 75th birthday. First things first, the image on the conference poster, website, banner, etc is not a psychedelic banana, but gravitational wave emission in a black hole merger. It’s a still from a numerical simulation done by a Cambridge group that you can watch in full on YouTube.
