AI just got a tough physics exam, and didn’t pass. PhysUniBench tests models on undergrad-level physics. Even top systems got only ~1 in 3 questions right. Why? Find out in our latest article 🔗#AI #Physics.

String theory isn’t just about strings anymore. From superstrings to branes, the field has transformed, raising the question: should it still be called “string theory”?. 🔗 #TheoreticalPhysics #StringTheory #MTheory.

What is AI, really?. From symbolic systems to neural networks, our latest Primer breaks down how today’s models learn, reason, and fall short of true understanding. 🔗 #AI #MachineLearning #DeepLearning #LLMs.

From technology to behavioural economics, the @SloanFoundation's thoughtful approach has shaped major shifts in science. Matt von Hippel (@4gravitons) explores its legacy as Adam Falk prepares to step down. 🔗 #Research #Science #Philanthropy.

From logic trees to language models, AI has come along way. However, it still falls short of reasoning like a scientist. Our latest post explores why scientific understanding requires more than pattern recognition. 🔗 #AI #Science #Reasoning.

Could Dyson spheres be stable? In our latest post, Matt von Hippel (@4gravitons) spoke with Colin McInnes to explore how binary star systems might support megastructures once thought impossible. 🔗#DysonSphere #Space #Engineering.

“This discovery was both profoundly puzzling and incredibly exciting.”. In this excerpt from Battle of the Big Bang (out May 29, 2025), Afshordi and Halper revisit cosmic origin stories and a gripping arc of scientific debate. 🔗 . #BigBang #Cosmology.

Gravity: weak by nature? Matt von Hippel (@4gravitons) explores the Weak Gravity Conjecture—why physicists suspect gravity must be the weakest force in any consistent theory of quantum gravity. 🧠 #Physics #QuantumGravity #WeakGravityConjecture.

Can science be magical? 🌌 Astrophysicist @JannaLevin lives at the crossroads of black holes & burning questions—where equations meet art, & dark energy might whisper of extra dimensions. Creativity isn’t a byproduct—it’s the method. 🔗 #astrophysics.

What is quantum gravity? This Primer introduces key ideas behind efforts to unify quantum mechanics and general relativity, for anyone curious about one of physics’ biggest unsolved puzzles. 🔗 #QuantumGravity #Physics.

AI is enabling new ways of studying the cosmos. Scientists like Shirley Ho (@cosmo_shirley) and Cora Dvorkin (@CoraDvorkin) use machine learning to reveal hidden structures in the universe. 🌌🔬 Read more: #AI #Cosmology #DarkMatter.

Is the pressure to publish shaping science for better, or worse? 📚⏳​Explore how today's academic incentives may be prioritizing quantity over quality in research:🎥 . Dive deeper with insights from @ivanoransky of @RetractionWatch:📖.

In an age of misinformation, scientific literacy means more than just reading—it’s about thinking critically, recognizing expertise, and evaluating evidence. Ethan Siegel (@StartsWithABang) unpacks what it really means to be scientifically literate:.🔗

Today is #WorldQuantumDay—a celebration of the field that has reshaped our understanding of nature and continues to drive innovation. Explore our latest posts on quantum science and technology 🔗 #WorldQuantumDay #QuantumScience

Benchmarking is a key step in separating quantum promise from practical progress. DARPA’s new initiative aims to assess whether error-corrected, utility-scale quantum computing is achievable within a decade. 🔗 #QuantumComputing #Benchmarking #QBI

A new study suggests open quantum systems may preserve time-reversal symmetry, even during decoherence. The results have sparked debate: do they challenge our understanding of the arrow of time, or restate known principles? Read more: #Physics #Research.

RT @4gravitons: New piece on a new startup in a new venue:

Physicists fully map the minimal Bell scenario, revealing all quantum correlations possible—even with partial entanglement. A step forward for theory and device-independent testing. 🔗#QuantumPhysics #ScienceNews.

AI has an energy problem. ⚡ But what if the solution isn’t more power? Matt von Hippel (@4gravitons) explores how @VaireHQ is building an energy-efficient chip based on physical reversibility. Read more: .#AI #SustainableTech.
