Can Water Create Infinity? - Terence Tao on Lex Fridman
🧑🔬✨ Meet the Speakers of Soapbox Science Brussels 2025! ✨🧑🔬
🔳 Introducing Sasha Viktorova, postdoctoral researcher in pure #mathematics, studying how shapes behave in higher dimensions and what happens at their most special points: #singularities.
📅 Catch her live on June 28th, 2PM, at Carrefour de l’Europe / Europakruispunt.
🤝 We are still looking for volunteers! Help us make this event a success and fill the form at https://lnkd.in/eCQEHMGp
🚀 Wow, who would've guessed #space-time #singularities aren't just #cosmic #drama queens with an existential crisis? Turns out they're harder to kill than a #B-movie villain with a secret contract. 🕵️♂️🔮 #Quanta Magazine’s deep dive into this is like trying to kill a vampire with a plastic spoon. 🥄🧛♂️

The #Zhukovsky #Aerofoil (sometimes transliterated as #Joukowsky from #Russian), is a 2D model of #streamlined #Airflow past a #wing. It uses #ComplexVariable and is an #AnalyticFunction (i.e. #Differentiable everywhere, save at isolated #Singularities). Take a circle in the #ComplexPlane which is not quite centred at the #origin but passes through the #coordinate (1,0) or (z=1+0i).

I've just discovered (should be Sir) Roy Kerr (https://en.wikipedia.org/wiki/Roy_Kerr) , #NewZealand mathematician famous for his solution for rotating black holes published a paper last month which showed #singularities do not have to exist in a #BlackHole, at least not how the 2020 Nobel prize winner Sir Roger Penrose described. For #Physics this is a huge deal. For #NewZealand media it wasn't worth a mention. But, here is a description of what he's done if you are game. https://flip.it/iwDh4a
What if #Singularities DO NOT Exist?

“You & Mia can’t become #singularities,” said Ava.
“Can’t guilt-trip us into staying together,” said Tom.
“Think,” said Dan. “Why aren’t you with her now?”
“It’s not about a wedding dress. Mia didn’t cancel an appointment. She’s too loyal,” said Ava.
“I need to go home.” #vss365
@TruthSandwich This forced me back to Hawking and Ellis.
They say, "One should probably also regard a null geodesically-incomplete spacetime as singular," for a couple of actually not very strong reasons.
(One is: the Reissner-Nordström solution is (a) singular, and (b) timelike geodesically complete but null incomplete. So let's hope the latter implies the former.)
And I guess everyone has just run with that ever since (other than Roy).
Roy Kerr vs. the singularities
http://www.unitaryflow.com/2023/11/roy-kerr-vs-singularities.html
"Although Roger Penrose won the Nobel Prize in physics just a few years ago for demonstrating how black holes come to exist in our Universe, singularities and all, the subject isn't closed. We've never peered beneath the event horizon, and have no way of detecting what's inside. Using a powerful mathematical argument, [Roy] Kerr argues that singularities shouldn't physically exist. He may be right."

We’re approaching an era of British mysteries where a one hour show is 59 minutes and 54 seconds of the detective being demonstrably depressed, and 6 seconds of the crime being solved by pulling up security camera footage from the exact moment and location of the crime. #tv #singularities #television
Mathematical analysis of singularities in the diffusion model under the submanifold assumption
It occurred to me that #resolution of #singularities is very similar to giving birth. The outcome is an exceptional line and a total transform of your life … #mathjoke (with apologies to #algebraicgeometers )
The new result shows that #blackholes gain #mass in a way consistent with them containing #vacuumenergy, providing a source of #darkenergy and removing the need for #singularities to form at their center.
