You can hear me discuss my new book, The Random Universe, with my colleague Brian Keating on his excellent Into the Impossible podcast.

An award-winning astrophysicist looks at how the understanding of uncertainty and randomness has led to breakthroughs in our knowledge of the cosmos All o...
Is the Universe pre-determined or random? In this conversation, @defjaf dives deep into why the universe may be fundamentally, intrinsically random. Plus: Is inflation on life support? What's the truth behind the Hubble tension? Is cosmology is approaching the event horizon,

Nobel prize in physics for the development of machine learning techniques. Interesting choice — incredibly consequential (it lies behind large language models like ChatGPT etc), but arguably not “physics”.

With work on machine learning that uses artificial neural networks, John J. Hopfield and Geoffrey E. Hinton “showed a completely new way for us to use computers,” the committee said.

"The Bizarre Shape of the Universe" Watch this YouTube video about COMPACT (@CompactCollab) and our PRL paper on cosmic topology: https://t.co/kip75qhuQp Thanks a lot, Elizabeth Fernandez (@SparkDialog), Jade Tan-Holmes and Tom Groenestyn for creating such an incredible video!

12/ 📚🔬 We chat about Marc's paper with Wang & @defjaf called the Polarization Pursuers Guide. The paper presented the possibility of measuring B-mode polarization of the CMB experimentally, inspiring me to design the experiment called BICEP which led to @BICEPTWO & @BICEP_Keck.

It is extraordinary that the USA gets treated to a dismantling of the Tory party orders of magnitude better than the tame efforts anyone dares attempt here. (And no, it's not the swearing that makes the difference - it's the accuracy of the attacks.) https://t.co/nWscZOrpiJ

Me, talking topology.
Here's your Monday afternoon listen 🎵📻 Professor Andrew Jaffe (@defjaf) from @ImperialPhysics was on @bbc5live to discuss his investigation into the shape of the universe 👇 https://t.co/4yNXbWC8Aj

I sometimes forget how important R.E.M. were to me, for a very long time.

Rather than stretching to infinity and beyond, the universe may have a topology that can eventually be mapped

An overview of the work we in @CompactCollab are doing to figure out the topology of the Universe. Thanks to @PhysRevLett for focussing on it.
The first report of the COMPACT Collaboration finds that Cosmic Microwave Background data does not yet rule out the Universe having nontrivial topology, such a twisted 3-torus. Letter: https://t.co/ugzWloTaYO
