UR: A Crisis in Cosmology? A new perspective on the Hubble Constant Tension
In our latest #UndergradResearch post, Sahil Ugale investigates the rate of expansion of the universe, and specifically the Hubble Constant Tension.

Tensions are rising with the beloved lambda-CDM model of the Universe. Is it time for Early Dark Energy to swoop in to save the day?
How can we use gravitational lensing to measure the expansion rate of the Universe?
Could the Hubble Tension finally be solved with a little spring cleaning? It’s more likely than you think.
The oldest objects in the universe weigh in on the heated debate over the “Hubble Tension,” disagreements on the expansion rate of the universe.
One of the most important issues in cosmology is the Hubble tension – why do different probes not agree on how fast the Universe is expanding? A popular solution is changing the physics in the very early Universe. Today’s paper explores, why this approach might not work, by measuring the expansion rate with observables independent of the early Universe.
