A Kurzgesagt animation on supernovae, the most powerful explosions in the universe. It explains their role in creating elements and what would happen to Earth if one occurred nearby.

Veritasium explains the many-worlds interpretation of quantum mechanics, drawing heavily on Sean Carroll's book. It walks through the Schrodinger equation and why wave collapse may be unnecessary if the universe keeps splitting.

The 2016 Isaac Asimov Memorial Debate, moderated by Neil deGrasse Tyson, in which a panel of physicists and philosophers debates whether the universe is a simulation. Participants include David Chalmers, Zohreh Davoudi and James Gates.

A very short clip of Carl Sagan saying that to make an apple pie from scratch you must first invent the universe. It illustrates how everything depends on a chain of prior things.

A short Tim and Eric Awesome Show sketch, The Universe I, II & III, in which the cosmos is shown in a deliberately absurd way. It is an Adult Swim surreal comedy bit.

Douglas Adams gives a talk at UCSB, recorded shortly before his death, about the odd lives of animals and what they suggest about humanity's future. It draws on his Last Chance to See work and is funny and wide-ranging.

David Tong, a Cambridge theoretical physicist, explains at the Royal Institution that the fundamental building blocks of nature are quantum fields rather than particles. He covers what we know about these fields and how they fit into the Standard Model.

An Every Frame a Painting video essay asking why Marvel films lack memorable musical themes. It blames temp tracks and directors scoring to filler music.

Sean Carroll introduces his video series on the biggest ideas in physics, such as symmetry, space and matter, as informal discussions with follow-up Q&A videos. This is the short opening video of the series.

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.

Max Brunsfeld of GitHub presents Tree-sitter, a parsing system for programming tools that supports incremental, error-tolerant parsing. He demos its integration into GitHub.com and Atom for syntax highlighting and code navigation.

The BBC TV version of the Babel Fish passage from The Hitchhiker's Guide to the Galaxy, with Ford and Arthur aboard a Vogon ship, narrated over the show's hand-drawn animated Guide entry.

A screencast showing how to use the fzf command-line fuzzy finder in the shell and in Vim. It covers searching files and also using the Vim plugin for help tags, buffers, lines and grep matches.

Veritasium explains how cosmic rays and other particles flip bits in computer memory, with examples including a Belgian election count error, plane incidents and game glitches. It is inspired by a RadioLab episode on bit flips.

Kurzgesagt explains why, even with science-fiction technology, most of the universe is permanently out of reach because of cosmic expansion and finite resources.

A PBS Space Time episode asking whether time began at the Big Bang. It explains that the Big Bang is not what most people were taught and what 'start' of the universe really means.

The Eames Office's 1977 film Powers of Ten starts at a picnic in Chicago and zooms out by a factor of ten every ten seconds to the edge of the universe. It then zooms inward to a proton in a carbon atom.

A visual scale comparison of stars and cosmic objects, from planets up to some of the largest known stars, set to music. It is meant to convey the vastness of the universe.

PBS Space Time explains the Hubble constant tension, in which two precise, independent methods of measuring the universe's expansion rate disagree. It covers why this calls some standard cosmology into question.

Kurzgesagt explains black hole stars, a hypothesized kind of giant star with a black hole at its core that could be a route to early supermassive black holes.

A 29-minute cinematic timelapse by melodysheep that journeys trillions of years into the future, covering the death of the sun, the end of stars, proton decay, black hole evaporation and the fate of the cosmos.

An Isaac Arthur episode on civilizations in the far future, past the Black Hole Era. It covers iron stars, Boltzmann brains, reversible computing and the idea of reversing entropy.

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 Symphony of Science music video that auto-tunes samples of Carl Sagan, Richard Feynman, Neil deGrasse Tyson and Bill Nye into a song about the wonder of the universe.

CGP Grey explains the elegant ratio of A4 and the metric paper sizes, then zooms out across scales from the Planck length to the observable universe.

Sabine Hossenfelder explains how special relativity leads to the block universe, in which past, present and future all exist equally, and asks what that means for whether the past still exists.

An Isaac Arthur episode on civilizations in the dark, post-stellar universe, including black hole farming, accretion disks and the Penrose process as energy sources.

A short video built around an animation of the roughly 10,000 galaxies in the Hubble Ultra Deep Field, placed at their measured redshift distances. It gives a brief history of deep field images and ends with a 3D fly-through.

A PBS Space Time episode asking whether the universe's information can ever truly be lost, tying quantum mechanics, determinism and black holes together. It sets up the black hole information paradox.

Stuart Armstrong of the Future of Humanity Institute gives an Oxford physics talk on what exploratory engineering suggests about the Fermi paradox. He argues that von Neumann probes and Dyson spheres are plausibly buildable and asks what traces advanced civilizations would leave.
