I am ABSOLUTELY THRILLED to announce that, as of June 1, 2022, I will be joining the @Perimeter Institute for Theoretical Physics as the inaugural
Hawking Chair in Cosmology and Science Communication
(auto-CCs at YouTube link)
More about the role: I'll be working with the Cosmology group and the Centre for the Universe at @Perimeter to continue my research into dark matter and the early universe. And I'll ALSO be working with Perimeter's fantastic outreach team to bring physics to the world!
I'm super excited to start my new position at @Perimeter in the spring! I'll still be maintaining my connection with @NCState, who have been extraordinarily supportive of my research and public science work since 2018, but I'll be living in Canada full time starting in June! 🇨🇦
I can't wait to start working with the whole Perimeter team in Waterloo!
One consequence of this move is that the postdoc ad I put out a little while back is now a bit out of date: jobs.ncsu.edu/postings/152233 -- I'm still hiring a postdoc, but it's now a joint position, with the option to be located at @Perimeter with me (and with a later start date).

I talk a little bit here about what cosmologists CURRENTLY mean when we say “the Big Bang” (a.k.a. “Hot Big Bang”) — the hot dense glowing plasma phase of the early universe. NOT a singularity. We don’t have any evidence a singularity ever happened!
Here, I talk about the language ambiguity around the term “the Big Bang.” It’s best to think of the Big Bang as the theory that the early universe was hotter, denser, and in some sense smaller than it is today. But a singularity isn’t part of that picture! vm.tiktok.com/ZM8gVfVxr/
This is the best belt (strong woven canvas with this cool buckle design) and I can’t for the life of me find somewhere to buy another one exactly like it. 😕 Anyone know anyone anywhere who sells these things? The original brand doesn’t anymore.
I have worn this belt nearly every day for like 20 years; I would love to find another one!
Update: Someone miraculously found exactly this model of belt on eBay! Unfortunately it was a small (32”) and mine is something like 39”. The search continues…
I know that “experimental astrophysics” & “experimental cosmology” typically refer to research using observatories or detectors for signals other than visible light to learn about the universe but it’s still fun to imagine they’re cooking up stars and black holes in the lab 👩🏼🔬🪐
Fusion researchers talk about "creating a star" in the lab (e.g., lasers.llnl.gov/education/how-…) but that's more like triggering the physics behind how stars work, which is not quite the same. Creating a black hole in the lab, though, might actually be possible angelsanddemons.web.cern.ch/faq/black-hole…
If CERN *did* create a black hole in the lab, it would tell us some very interesting things about our Universe! It would confirm some speculative theories about the possibility of higher dimensions of space, and it would even give us hints about the stability of the Universe (!)
I will report back as to whether I see any incredible aurora and/or discover any downsides to being airborne at high altitude during a geomagnetic storm 🤩😬
Just spoke with @LBC about the discovery of what might be a planet in another galaxy: bbc.com/news/science-e…
Which is very exciting! But (and I didn't get to this in the interview) there are reasons to be skeptical about this claim.
The astronomers observed a dip in the bright x-ray light from a binary system consisting of a massive star locked in an orbit with a compact stellar remnant: a black hole or neutron star. The claim is a planet passed in front of the system and briefly blocked the x-ray emission.
Such a "transit" event is certainly plausible -- we've detected thousands of exoplanets via transits in our own galaxy! But this case would be a VERY lucky situation. The alignment would have to be perfect and the timing EXTREMELY lucky to have caught it.
At Nashville Airport, heading home shortly. Mask use here (as in all US airports) is mandatory, but is currently standing at about 50%. Maaaaaybe as high as 70% if you pretend that noses don’t exist. 😑
See you soon Raleigh
I am back in Raleigh! My suitcase, alas, is not ready to come home yet. The airline tells me it will be on its own flight tomorrow afternoon. While I respect its desire to assert its independence, I would really have preferred having access to my clothes and toothbrush tonight.
