In response, theorists have proposed extensions to ΛCDM. None have yet achieved a consensus.
About 13.8 billion years ago, the universe began as a "singularity"—a point of infinite density and heat. In a fraction of a second, an event called caused the universe to expand exponentially. As it cooled, subatomic particles formed, eventually leading to the creation of hydrogen and helium. The Smoking Gun: Cosmic Microwave Background (CMB) cosmology
It wasn't random noise. It was a swirl. A distinct, spiral polarization in the primordial light. In response, theorists have proposed extensions to ΛCDM
The screen flickered. A pattern emerged. subatomic particles formed
