The Man Who Corrected Einstein
Einstein’s equations of general relativity initially implied a universe that could not expand or contract—but a subtle technical mistake forced him...
Why Time Flows Differently Between Galaxies
A December paper by Antonia Seifert and collaborators at the University of Canterbury argues that the universe’s apparent acceleration might be an...
Why You Didn't Choose If You Clicked On This Video Or Not - The Illusion Of Freewill
A click on a YouTube thumbnail is treated as the end point of a chain so long and tightly constrained that “free will” looks like an illusion. The...
Black Holes Could Explain Dark Energy
Dark energy may be explainable by black holes—specifically a scenario where black holes “feel” the universe’s expansion, causing their masses to grow...
The Banana Bridge - The Unitary Kinematic Solution to the Hubble Tension and the 1.618 x 137 Master Law
This paper addresses a central problem in observational cosmology: how to convert geometric distance measurements in the Milky Way into an accurate...
Extended dark energy analysis using DESI DR2 BAO measurements
This paper asks whether the late-time acceleration of the Universe is consistent with a cosmological constant (ΛCDM) or instead requires dynamical...
New constraints on interacting dark energy from DESI DR2 BAO observations
This paper asks how new Baryon Acoustic Oscillation (BAO) measurements from DESI Data Release 2 (DR2) constrain models in which dark energy (DE) and...
KiDS-Legacy: Cosmological constraints from cosmic shear with the complete Kilo-Degree Survey
This paper asks how well the completed Kilo-Degree Survey (KiDS) can constrain late-time structure growth and cosmology using cosmic shear,...

This paper addresses a central question in modern cosmology: is dark energy (DE) consistent with a cosmological constant ( \(w=-1\)) or does it...
Modified Gravity Realizations of Quintom Dark Energy after DESI DR2
This paper asks whether the “quintom” form of dynamical dark energy—specifically an equation-of-state (EoS) parameter that crosses the phantom divide...
Independent connection in action during inflation
This paper asks whether the inflationary epoch can be explained without introducing an ad hoc inflaton sector, by instead using a dynamical affine...
