Could Quantum Gravity Save Physics?

We examine the current state of Lambda Cold Dark Matter (Lambda CDM), our best model of cosmology. While it remains the reigning champion of cosmology, it is facing an unprecedented onslaught of data from the James Webb Space Telescope (JWST) and advanced underground detectors that are stirring up revolutionary questions. Lambda CDM has brilliantly predicted the Cosmic Microwave Background (CMB), the distribution of galaxies in colossal filaments, and the chemical elements forged just after the Big Bang. However, several "tensions" are pushing the model to its limits.

We examine the current state of Lambda Cold Dark Matter (Lambda CDM), our best model of cosmology. While it remains the reigning champion of cosmology, it is facing an unprecedented onslaught of data from the James Webb Space Telescope (JWST) and advanced underground detectors that are stirring up revolutionary questions.

Lambda CDM has brilliantly predicted the Cosmic Microwave Background (CMB), the distribution of galaxies in colossal filaments, and the chemical elements forged just after the Big Bang. However, several "tensions" are pushing the model to its limits.
