With LIGO, JWST the construction of the Square Kilometer Array, and the ICECUBE Neutrino detector, we are opening new windows on the Universe. If history is any guide, we will be surprised.
Lawrence, what are your thoughts on the size of the galaxies at redshift z~13 that JWST has discovered?

Some are saying they are too large and potentially incompatible with LCDM. https://arxiv.org/abs/2208.01611
Not enough baryonic mass for the size of those early galaxies?
What do you think?
There is tension.. could be a problem.. or could just be a selection effect.. We will see.
LIGO acronym stands for Laser Interferometer Gravitational-Wave Observatory, in case anyone didn’t know which I doubt if they are reading this.
