Rob Sheldon: This article illustrates the reason why the scientific method is going extinct, not just in Darwin’s circular logic, but also in physics and cosmology.

Rob Sheldon: Are multiple measurements “closing in” on dark energy? Nope.
If the results had been at all positive, the presser would have likely said “Confirmation!!!!” or something like that. Seeing as the new results are neutral or faintly negative, “closing in” is the best they can manage.
Dark matter vs. dark energy in a world where neither have been discovered
Hossenfelder’s clarifications will at least help us understand what we are all confused about.
Our universe understood at last: An expanding bubble in an extra dimension!
The authors hope that their work will “pave the way for methods of testing string theory.” That could come in handy, you never know.
Could new galactic measurements “upend current theories” of physics?
At Horizons EU we are told, “New efforts to figure out just how fast the universe has expanded since the Big Bang, a speed known as the Hubble constant, could upend current theories of physics , according to some scientists. If current theories were upended, who would know. Consider these stories from this month alone: […]
Biggest mystery in cosmology may not exist says top physicist
That’s dark energy.topic The most mysterious phenomenon in cosmology – dark energy – may not exist at all, according to Professor Subir Sarkar, head of the particle theory group at the University of Oxford in the UK. In the late 1990s, astronomers found evidence from supernovae that the universe has been expanding faster and faster […]
Researchers: Either dark energy or string theory is wrong. Or both are.
Dark energy. Even the name is intriguing. Isn’t it a line of cosmetics already? But the evidence base is getting murkier all the time. The conjecture, if true, would mean the density of dark energy in our universe cannot be constant, but must instead take a form called “quintessence” — an energy source that will […]
Researchers: The symmetrons needed to explain dark energy were not found
From ScienceDaily: One of the candidates for ‘dark energy’ is the symmetron field. Researchers have developed an experiment capable of measuring extremely small forces with the help of neutrons. The measurements could have provided pointers to the mysterious symmetrons, but the particles didn’t show up. This excludes the possibility of symmetrons in a broad parameter […]
