Ask Dr B: Is the multiverse science? Is the multiverse real? Dear Dr B: Can you think of a single advancement in theoretical physics, other than speculation, since the early 1980’s? Dear Dr. B: What do physicists mean when they say time doesn’t exist? No evidence for spacetime foam How can we test quantum gravity? The LHC “nightmare scenario” has come true The Philosophy of Modern Cosmology (srsly) Where are we on the road to quantum gravity? Hey Bill Nye, Please stop talking nonsense about quantum mechanics. What makes an idea worthy? An interview with Anthony Aguirre What if the universe was like a pile of laundry? Sorry, the universe wasn’t made for you Yes, a violation of energy conservation can explain the cosmological constant No, physicists have not created “negative mass” New paper claims string theory can be tested with Bose-Einstein-Condensates Self-tuning brings wireless power closer to reality Dear Dr B: Why are neutrinos evidence for physics beyond the standard model? I totally mean it: Inflation never solved the flatness problem. The Bullet Cluster as Evidence against Dark Matter Space may not be as immaterial as we thought How Popper killed Particle Physics Naturalness is dead. Long live naturalness. How do you prove that the Earth is older than 10,000 years? Astrophysicist discovers yet another way to screw yourself over when modifying Einstein’s theory The cosmological constant is not the worst prediction ever. It’s not even a prediction. Research perversions are spreading. You will not like the proposed solution. Reasoning in Physics Sometimes I believe in string theory. Then I wake up. Pure Nerd Fun: The Grasshopper Problem Physics Facts and Figures Shut up and simulate. (In which I try to understand how dark matter forms galaxies, and end up very confused.) The Multiworse Is Coming Modified Gravity and the Radial Acceleration Relation, Again Hawking’s “Final Theory” is not groundbreaking Particle Physicists begin to invent reasons to build next larger Particle Collider Book Review: “Farewell to Reality” by Jim Baggott No, that galaxy without dark matter has not ruled out modified gravity A black hole merger… merger… merger The Overproduction Crisis in Physics and Why You Should Care About It Looking in the Wrong Places New results confirm old anomaly in neutrino data MiniBooNE
Reports of sterile neutrino’s resurrection may be greatly exaggerated Physicist concludes there are no laws of physics. There Are No Laws of Physics. There’s Only the Landscape. Astrophysicists try to falsify multiverse, find they can’t. How nature became unnatural Limits of Reductionism No, we probably dont live in a computer simulation Evidence for modified gravity is now evidence against it. A bad prior can give you misleading results. 10 physics facts you should have learned in school but probably didn’t Guest Post: Tam Hunt roasts Carlo Rovelli about the Nature of Time Penrose claims LIGO noise is evidence for Cyclic Cosmology Get your protons right! Roger Penrose still looks for evidence of universal rebirth Science has a problem, and we must talk about it Superfluid dark matter passes another check: strong gravitational lensing Dear Dr B: What do you actually live from? First stars spell trouble for dark matter String theory pros and cons String theory pros and cons Dark matter. Or what? Superfluid Dark Matter Physics may be up against the wall, anno 1986 Modified gravity, demystified New paper claims that LIGO’s gravitational wave detection from a neutron star merger can’t be right The present phase of stagnation in the foundations of physics is not normal CERN produces marketing video for new collider and it’s full of lies No, negative masses have not revolutionized cosmology Don’t ask what science can do for you. Black-hole computing

How the LHC may spell the end of particle physics Electrons don’t think Letter from a reader: “What’s so bad about randomness?” If it quacks like a black hole Good Problems in the Foundations of Physics Just because it’s falsifiable doesn’t mean it’s good science. When gravity breaks down Dark Matter – Or What? Never again confuse Dark Matter with Dark Energy What Is Dark Energy? | Full Debate | Erik Verlinde, Sabine Hossenfelder, Catherine Heymans Science has a problem. Here is how you can help. Nonsense arguments for building a bigger particle collider that I am tired of hearing (The Ultimate Collection) Dear Dr B: Does the LHC collide protons at twice the speed of light? Is the universe a hologram? Gravitational wave interferometers may tell us. Does the world need a larger particle collider? How Heroes Hurt Science The LHC has broken physics, according to this philosopher When Beauty Gets in the Way of Science Quantum gravity phenomenology \neq detecting gravitons Comments on “Quantum Gravity in the Lab” in Scientific American Yes, scientific theories have to be falsifiable. Why do we even have to talk about this? Quantum Mechanics is wrong. There, I’ve said it. 10 things you should know about black holes SFI Community Lecture – Sabine Hossenfelder – How Beauty Leads Physics Astray Was läuft falsch in der gegenwärtigen Physik? Does the Higgs-boson exist? Do I exist? Do I exist? Quantum Physics: Still mysterious after all those years Does God exist? Science does not have an answer. The multiverse hypothesis: Is our universe the only one? If we spend money on a larger particle collider, we risk that progress in physics stalls. Guest Post: A conversation with Lee Smolin about his new book “Einstein’s Unfinished Revolution” Physicists are out to unlock the muon’s secret Book review: “Einstein’s Unfinished Revolution” by Lee Smolin Brace for the oncoming deluge of dark matter detectors that won’t detect anything Quantum Supremacy: What is it and what does it mean? Dr. Sabine Hossenfelder No, we will not open a portal to a parallel universe Why the multiverse is religion, not science M is for Maggot, N is for Nonsense Science Shrugs Special Breakthrough Prize awarded for Supergravity How we know that Einstein’s General Relativity can’t be quite right How do black holes destroy information and why is that a problem? Solutions to the black hole information paradox What’s up with LIGO?
