JWST Found Six 'Impossible' Galaxies. Here's What The Researchers Have To Say

James Webb recently found six examples of galaxies that are too big too early. This discovery can significantly change our understanding of the early Universe. In this interview, I'm talking with Dr Joel Leja, who is a part of the team behind the research.

Loved this interview. He's nice to listen to and seems to be brimming with passion for what he does. Would love a follow up interview in the future based on the results of their research.

Joel is so genuine and pleasant, he really is. Such a nice interview.

[TomSnyder--theJaz]

Dr. Joel Leja makes the understanding of the early Universe an approachable subject for your viewers.
Well done, Dr. Joel. (...you too, Fraser ;)
Cheers!

Just as a side note, Sabine listed finding huge galaxies early on as a likely discovery of JWST back in 2021. She did many videos on the inconsistencies of lambda-CDM and how "einstein is right" is a terrible oversimplification of recent astronomical results like the black hole pictures. While space curvature theory is solid, its extension to large scale has gaping holes in it, it is leaking water from every possible direction and bandaids are almost as big as the theory itself

I hope that is just the first of many interviews with this man. It was a really good one

[jamesmnguyen]

Your questions are always on point and really drive the interviews.

[cittaaukoto_japan]

This is a great interview. Fraser got the interviewee to reveal some of his initial findings. The questions were pointed but not aggressive and he gently coaxed the answers out.

[svendrastrupandersen]

What a great interview! You really know how to shatter the coarse and clickbaity headlines, and give us real food!

[MikeKinney]

Great interview, Fraser . This topic is the one that has interested
me the most, since JWST has been looking as far back, as it can.

[Nikolaj]

This dude complimented every question, lol.
"That's a really good question, i appreciate that."

[JaydogPDX]

You Sir are refreshing change of pace! Thank you for the lack of commercials!

I really appreciate how careful Universe Today is <3

[WthyrBendragon]

As a layperson I might theorize that since the pre-expansion universe was much smaller when these galaxies formed there may be a way they accreted more quickly than our current expectations.

"It's like going to check on your two year old toddler and finding a fully grown adult." I loved that.

[GRILL]

Great interview!! And great questions like “tell me how your wrong”. Frazier you were born for this.

[erikhumleker]

I love it that we didn't find what we expected...that's what makes science so interesting

[hikingpete]

What a fantastic guest. He interviewed well.

[squankey]

What if the universe is older than we think it is? Maybe over those distances and "time" there is some other phenomenon that affects the red shift throwing off our models of the age of the universe.

[louisgiokas]

The comment near the end about lambda-CDM being an "ancient" theory is amazing to me. It was proposed in 1982. I was a physics student in the early 1970s. I worked in the High Energy Physics department at a large university. The department had a small library and there was a bookshelf, about three feet wide, of cosmology books. I spent a little time looking through these. Of course, back then the big bang was not universally accepted and there were several models still considered current. So to say that it is ancient makes me feel ancient. It also shows a little hubris on the part of Leja.

This guy is an excellent, very fun presenter. Great sense of humor!
