John Batchelor and I welcomed Dr. Anshu Gupta from Perth, Australia to discuss her theory and work relating to the extreme brightness of early galaxies. Check out the LiveSci=nce article "James Webb telescope finds an 'extreme' glow coming from 90% of the universe's earliest galaxies" at https://www.livescience.com/space/astronomy/james-webb-telescope-finds-an-extreme-glow-coming-from-90-of-the-universes-earliest-galaxies#:~:text=Astronomy-,James%20Webb%20telescope%20finds%20an%20'extreme'%20glow%20coming%20from%2090,of%20the%20universe's%20earliest%20galaxies&text=The%20universe's%20early%20galaxies%20are,primordial%20galaxies%20may%20explain%20why. In addition, you can access Dr. Gupta's paper, "MOSEL survey: JWST revels major mergers/strong interactions drive the extreme emission lines in the early universe" at https://iopscience.iop.org/article/10.3847/2041-8213/ad0788. During our discussion, our guest described her research and her work with both JWST and Hubble, explained the bright gas cloud which is what is being seen and why it was with the earliest galaxies because with later ones they change and also the bright gas cloud has diminished over time. In the last part of the program John offered her an unlimited budget. With such a budget, our guest told us what her priorities would be with the funds. Don't miss what she said as you might find some surprises in her commentary.
