#BattleoftheBigBang (w/ @philhalper.bsky.social) is back in @thewallstreet.bsky.social — this time in the “Five Best: Cosmic Origins and Endings” feature selected by @dreochapman.bsky.social, alongside Stephen Hawking, Steve Weinberg, Simon Singh, and @astrokatie.com 🎉 www.wsj.com/arts-culture...

What do (real) physicists think about the big unanswered questions in fundamental physics? Niayesh Afshordi @nafshordi.bsky.social has made a page presenting results of an APS survey he did with Phil Halper. nafshordi.github.io/aps-dashboard/

American Physical Society survey on 'big mysteries' reported by @nafshordi.bsky.social et al. reveals a land of contrast ;) arxiv.org/abs/2605.11058

The largest survey of physicists ever conducted is out. They were asked their opinions on the Big Bang, Dark Matter, Dark Energy & more. We discuss the results in a new video with @seanmcarroll.bsky.social and @nafshordi.bsky.social and @ghazalgesh.bsky.social www.youtube.com/watch?v=6B00...

The research team behind this work was led by Dr. Niayesh Afshordi, associate faculty at Perimeter Institute and professor of physics and astronomy at @uwaterloo.ca. Learn more: perimeterinstitute.ca/news/new-the...

Causal Set Theory predicted dark energy 10 years before its discovery. Here we explore this quantum gravity proposal with its originators, exploring cyclic universes, black holes, the nature of time and fine-tuning with @nafshordi.bsky.social www.youtube.com/watch?v=5EoZ...

You can't... repeal... a scientific finding. At that point it's just called lying about it.

What have our members achieved in the last year..? Quite a lot it turns out. qspace.fqxi.org/news/165315/... @alyssaney.bsky.social @nicoleyh11.bsky.social @seanmcarroll.bsky.social @nafshordi.bsky.social @saraimari.bsky.social @rovelli.bsky.social @coecke.bsky.social @postquantum.bsky.social

If you’re searching for a gift for someone who loves real science — not the click-bait shortcuts — Battle of the Big Bang might be the cosmic spark you’re looking for. (1/3)

🚀 New(ish) paper! With my student Ruolin Liu and Jérôme Quintin, we show how quadratic gravity can offer an ultraviolet completion of the Big Bang. Its renormalization group flow yields arguably the first UV-complete inflation model without ghost instabilities. (1/3)

What triggered the Big Bang, a new paper from @nafshordi.bsky.social and colleagues suggests that an old theory fo quanutm gravity might be the answer and looks to fit new data better than standard cosmology. All explained in this new video www.youtube.com/watch?v=TZeL...

We spoke to Hassan recently at @perimeterinstitute.ca, where he's working with @nafshordi.bsky.social to detect quantum echoes in #GravitationalWaves as a way to prove #QuantumGravity.

Yesterday I was waiting at an ICE office with a client to make sure that she was not going to get deported. It was a 5 hour excruciating wait without internet access and I was reading the book, Battle of the Big Bang by @nafshordi.bsky.social This passage made me stop and rethink reality :)

I also texted a physicist friend, Spiros Michalakis (when I would get reception occasionally) about the passage and he agreed and asked me about the book. Thank you to @seanmcarroll.bsky.social for the podcast with @nafshordi.bsky.social which intrigued me enough to get the book.

🎃 Haunted Cosmology Celtic Tour: Dublin & Edinburgh 🕯️ This October, Phil and I are taking our ghost-hunting into the heart of cosmology. Join us for a journey through cosmic ghosts, phantoms, and monsters — not from folklore, but from the deepest mysteries of physics. (1/4)

Oh, hi, yeah by the way, US democratic party, Trump is getting the credit for this peace deal because you were so useless. Trump. Think about that.

New Debate Out Now “Has Science Just Proved God?” I had the privilege of debating alongside Michel-Yves Bolloré, under moderator John Nelson, on whether modern science points toward a divine creator. Watch here ▶️ youtu.be/DO5iArbukzg #ScienceAndFaith #Cosmology #Philosophy (1/2)

Thanks @danfalk.bsky.social and @reviewcanada.bsky.social for this thoughtful review of our #BattleoftheBigBang @philhalper.bsky.social @uchicagopress.bsky.social

Why dark energy does not rule out a cyclic cosmos. @nafshordi.bsky.social and I debunk this commonly held myth in our new video www.youtube.com/watch?v=dHzo...

@chanda.bsky.social was my first PhD student, and this was my first PhD cake! She has now surpassed me in every way, and I couldn’t be prouder.

Thanks @chanda.bsky.social for the plug! @uchicagopress.bsky.social

Celebrate this anniversary with me by 1. Preordering my next book

I’m doing a public talk with @perimeterinstitute.ca in Waterloo! www.eventbrite.ca/e/how-the-un... (Tickets are free but you have to be quick — Eventbrite ticket reservations open at 9am Eastern Sep 2, which is in… 5 minutes)

What if scientists hadn’t waited until this point to speak about politics Every time I see a headline like this, my brain just shouts Like what if scientists hadn’t sat around silently watching everyone around them get attacked Maybe the fight on campus would have gone differently

The only prayer that matters when it comes to the regular and repeated murder of American children while they are at school is the kind of prayer that is taking action, the kind of prayer that materially fights for the living, the kind of prayer that says "never again" and means it, from MN to Gaza.

Time is running out to apply for our workshop: "50 years of the black hole information paradox: November 3 -7 , 2025" at Simons Center for Geometry and Physics scgp.stonybrook.edu/archives/45328

This is one of the worst developments in higher education in an era of terrible developments. If faculty classroom speech is government speech, there’s no such thing as academic freedom. It would lead to a collapse of free inquiry and classical liberal education.

#BattleoftheBigBang is having a party 🥳
