Backreaction: No, the black hole information loss problem has not been solved. Even if PRL thinks so.
http://backreaction.blogspot.com/2015/04/no-black-hole-information-loss-problem.html
Talk To A Physicist. Talk To A Philosopher. Tuesday, April 07, 2015. No, the black hole information loss problem has not been solved. Even if PRL thinks so. This morning I got several requests for comments on this paper which apparently was published in PRL. Radiation from a collapsing object is manifestly unitary. Anshul Saini, Dejan Stojkovic. PhysRev.Lett. 114 (2015) 11, 111301. What’s new about this? The authors in the paper never trace out the part behind the horizon, so it’s not surprising th...
Backreaction: No, you cannot test quantum gravity with X-ray superradiance
http://backreaction.blogspot.com/2015/03/no-you-cannot-test-quantum-gravity-with.html
Talk To A Physicist. Talk To A Philosopher. Monday, March 23, 2015. No, you cannot test quantum gravity with X-ray superradiance. I am always looking for new ways to repeat myself, so I cannot possibly leave out this opportunity to point out yet another possibility to not test quantum gravity. Chris Lee from Arstechnica informed the world last week that “ Deflecting X-rays due to gravity may provide view on quantum gravity. 8221;, which is a summary of the paper. By Wen-Te Liao and Sven Ahrens. Well, not...
Backreaction: The eternal tug of war between science journalists and scientists. A graphical story.
http://backreaction.blogspot.com/2014/02/the-eternal-tug-of-war-between-science.html
Talk To A Physicist. Talk To A Philosopher. Friday, February 21, 2014. The eternal tug of war between science journalists and scientists. A graphical story. We can summarize the problem in this graph:. Scientists are on the average more pessimistic about the total amount of information that can be conveyed to begin with because they do not only believe but know. So it seems this tug of war is unavoidable, but let us have a look at the underlying assumptions. Labels: Science and Society. Is advanced towar...
Backreaction: What are natural units?

Talk To A Physicist. Talk To A Philosopher. Monday, November 07, 2011. What are natural units? At 3:20min it should be 5000K, not 500K, sorry about that. At 3:30min, Lara tried to eat the keyboard. Temperatures in GeV and distances as the inverse of an energy. Dress it up in formal attire. Check that, too. Yer gonna be temps in GeV rich! 10:16 AM, November 07, 2011. Thanks, Bee.

Backreaction: Pre-Print Peer Review
http://backreaction.blogspot.com/2012/02/pre-print-peer-review.html
Talk To A Physicist. Talk To A Philosopher. Thursday, February 16, 2012. Nature news titled recently that "Rebel academics ponder how to break free of commercial publishers". The rebels would be better off if they'd read this blog, because we have discussed here a solution to their problem! In contrast to more radical options, PPPR has a good chance of success because it is very close to the present system and would work very similar. And it is of advantage for everybody involved. Discussion forum. I...

It is even more interesting to plot the W. Cross section against the W. Cross section, because the asymmetry between W. In a low pile-up configuration in or...

CMS resolves states with a mass difference of 19 MeV | Collider Blog
https://muon.wordpress.com/2014/09/27/cms-resolves-states-with-a-mass-difference-of-19-mev
CMS resolves states with a mass difference of 19 MeV. September 27, 2014 at 4:56 pm. This week the CMS Collaboration released a paper reporting the measurement of the ratio of production cross sections for the χb2(1P) and the χb1(1P) heavy meson states ( arXiv:1409.5761. The motivation stems from the theoretical difficulties in explaining how such states are formed, but for me as an experimenter the most striking feature of the analysis is the impressive separation of the χ states. The mass of the χb...

Talk To A Scientist. Wednesday, March 14, 2018. Stephen Hawking dies at 76. What was he famous for? I woke up this morning to the sad news that Stephen Hawking has died. His 1988 book “A Brief History of Time” got me originally interested in physics, and I ended up writing both my diploma thesis and my PhD thesis about black holes. It is fair to say that without Hawking my life would have been an entirely different one. Thanks to this seminal work, physicists understood that the singularities in General ...
