Sabine Hossenfelder: Are dark matter and dark energy scientific?

Hossenfelder: “So, what’s the scientist to do when they are faced with such a discrepancy between theory and observation? They look for new regularities in the observation and try to find a simple way to explain them.” Okay but the question of whether the terms “dark matter” and “dark energy” correspond to anything that actually exists could be a different one.

Rob Sheldon on dark energy: Does it exist?

Sheldon, our physics color commentator, writes to say, “I’ve mentioned before that Subir Sarkar at Oxford has questioned the existence of “dark energy” and by implication, the award of the 2011 Nobel prize. Sabine Hossenfelder’s blog links to a 7 minute summary of the Nobel prize and Sarkar’s work: But even more compelling is her Read More…

So then maybe we ARE privileged observers

Researcher: “Our analysis is data-driven but supports the theoretical proposal due to Christos Tsagas (University of Thessaloniki) that acceleration may be inferred when we are not Copernican observers, as is usually assumed, but are embedded in a local bulk flow shared by nearby galaxies, as is, indeed, observed. This is unexpected in the standard cosmological model, and the reason for such a flow remains unexplained.

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 Read More…

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 Read More…
