The NEW Crisis in Cosmology
Cosmology’s “Hubble tension” has sharpened rather than softened: two high-precision ways of measuring the universe’s expansion rate still disagree,...
Is The Universe Finite?
A new analysis of cosmic microwave background data is reviving a long-running question in cosmology: is the universe finite and “closed,” or infinite...
How We Know The Universe is Ancient
Astronomers can assign a precise “birthday” to the universe—about 13.8 billion years ago—even though no direct relic from the first moments survives....
The Crisis in Cosmology
Cosmology is facing a direct, high-precision standoff over one number that ties the universe’s past to its future: the Hubble constant (H0), the...
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...
Constraints on neutrino physics from DESI DR2 BAO and DR1 full shape
This paper asks how well current large-scale structure (LSS) measurements can constrain neutrino properties—specifically the sum of neutrino masses...
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...
