Rebecca Watson's video critiquing physicist Sabine Hossenfelder's earlier video on gender care for transgender minors, arguing it mishandled the evidence.

Quanta Magazine explains the 2022 experiment that claimed to create a holographic wormhole on Google's quantum computer. The description now notes that a later independent analysis questioned whether any wormhole was created.

Physicist Jacob Barandes discusses his view that quantum mechanics can be formulated without wave functions, using a stochastic, probabilistic approach. The long interview covers measurement, the foundations of quantum theory and the history of the field.

Physicist Sabine Hossenfelder explains how 5G works and examines the health concerns around millimeter wave radiation. She reviews the scientific evidence and the open letters from scientists.

Physicist Angela Collier's roughly hour-long video on how string theory was hyped to the public and what that did to science communication. She traces the history of the theory as a narrative and argues it is interesting but was oversold.

Physicist Angela Collier argues that dark matter is not a theory but a set of observations, covering rotation curves, the CMB and why modified gravity struggles to explain them.

Physicist Angela Collier's nearly three-hour critique of Richard Feynman's public legacy. She examines how his books, written with Ralph Leighton, shaped a mythologized great-man image, and covers his personal behavior.

Veritasium explores why energy is not conserved in general relativity, using Emmy Noether's theorem linking symmetries to conservation laws. Physicists interviewed explain energy loss in an expanding universe.

Lex Fridman interviews physicist Roger Penrose on consciousness, the limits of computation, quantum mechanics and his cyclic cosmology. It covers his views on AI and the big bang.

Angela Collier, a physicist, revisits her earlier dark matter video, explaining dark matter as a set of observations rather than a theory and discussing MOND comments.

Physicist Angela Collier gives an hour-long critique of Avi Loeb's alien claims and reputation, placing them within the broader topic of physics crackpots. The Loeb discussion starts around the 24 minute mark.

Fraser Cain interviews JPL physicist Slava Turyshev about using the Sun's gravity as a lens to image distant exoplanets. They cover how the lens works, how a spacecraft would align with it, and mission design.

Lex Fridman interviews Harvard astrophysicist Avi Loeb about the interstellar object Oumuamua, aliens and black holes. Loeb lays out his argument that it may be an artifact rather than debris.

Physicist Angela Collier rants for 42 minutes about why violin plots are a poor way to show data, citing papers on violin and bean plots. It is part lecture on how to read distributions and part opinionated critique.

Physicist Angela Collier uses Gell-Mann amnesia to critique pop-science figures, especially Michio Kaku, and works through an eigenvalue problem along the way. It is a long, rambling commentary on how experts see simplified explanations of their own field.

Physicist and YouTuber Angela Collier argues in this hour-long video that AI as commonly described does not really exist. She covers the limits of the tools, biased datasets, and why they should not be used to make decisions.

Theoretical physicist Nima Arkani-Hamed gives a public talk on why spacetime may not be fundamental and what might replace it, including newer approaches to scattering amplitudes.

Lex Fridman interviews MIT physicist Max Tegmark, co-founder of the Future of Life Institute, about the case for pausing giant AI experiments and the risks of advanced AI.

Physicist Angela Collier critiques 'vibe physics', the idea that non-experts or billionaires can make scientific discoveries by chatting with AI chatbots, drawing a parallel with vibe coding.

Astrophysicist Dr. Becky explains the Hubble tension, the disagreement between expansion-rate measurements from the cosmic microwave background and the distance ladder, and what early JWST Cepheid observations add.

A PBS Space Time episode asking whether our universe could sit inside a black hole. It covers what physicists think happens inside black holes and the arguments for and against this idea.

Veritasium explores what general relativity says about black holes, white holes and wormholes, with help from physicists Geraint Lewis and Juan Maldacena. It introduces Penrose diagrams and the idea that other universes may be implied.
