In briefVeritasium 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.
In briefA brief demonstration of a railroad tank car imploding after a vacuum is pulled with its safety valves disabled.
In briefUSLaunchReport footage of the September 2016 SpaceX Falcon 9 static fire anomaly that destroyed the rocket and AMOS-6 satellite at Launch Complex 40.
In briefA two-minute minutephysics video explaining why turning a bicycle requires first steering briefly the other way. It covers counter-steering and balance with slow-motion footage and 3D animation.
In briefAn animated Gabbard diagram of objects in low Earth orbit from 1959 to 2021, showing altitude over time. It highlights major debris-generating events and how low-altitude debris decays out of orbit.
In briefThunderf00t applies a simple energy mass balance to weight loss, showing how much exercise is needed to burn off extra calories compared with eating less. He concludes that cutting intake is the easier route and that hunger fades after the first week.
In briefPhysics Girl shows a vortex phenomenon (a falaco soliton) that can be reproduced in a pool on a sunny day. Two vortices are created with plates and made visible with food coloring.
In briefDave Jones of EEVblog demonstrates that a frequency counter can detect gravity through the 2g tipover effect on quartz crystal oscillators. He shows the reading shift as the instrument's orientation changes.
In briefA controlled demonstration by Wabash National of a tank trailer collapsing under vacuum, staged at an industry expo. The tank implodes as air is pulled out.
In briefA short, humorous critique of Helion Energy's fusion approach, framed as a response to a Real Engineering video. It covers low reactivity, neutron production, bremsstrahlung losses and diagnostics.
In briefA short National Geographic piece showing a laser system that tracks and kills mosquitoes, filmed in slow motion, as part of anti-malaria efforts. It comes from Intellectual Ventures' 2010 work.
In briefLex Fridman's long conversation with Elon Musk covering SpaceX, Mars, Tesla Autopilot and self-driving, robotics and AI.
In briefA short test firing of the XRS-2200 linear aerospike engine at NASA Stennis Space Center, which was designed for the cancelled X-33 VentureStar. The engine is shown at roughly 80 percent of max thrust.
In briefElon Musk's 2016 IAC presentation on the technical challenges and architectures for building a self-sustaining human presence on Mars.
In briefCody's Lab obtains pure heavy water (D2O) and drinks it as a taste test, reporting its flavor and feel. It is a short self-experiment.
In briefA compilation of hover tests of exoatmospheric kill vehicles, the small rocket-propelled interceptors used in missile defense, including early prototypes from the late 1980s. It shows the vehicles maneuvering with thrusters in test facilities.
In briefSciencium examines the Mpemba effect, the claim that hot water freezes faster than cold water. It walks through experiments and a published paper questioning the effect.
In briefShort British Pathe newsreel footage of the 1940 collapse of the Tacoma Narrows Bridge as it twisted and swayed in the wind. The only casualty was a dog left in a stalled car.
In briefBenn Jordan measures air quality around vinyl records with a pollution meter and finds high particulate and VOC levels. He argues vinyl should be modernized.
In briefA performance recording of Alvin Lucier's 1969 experimental piece in which a spoken text is repeatedly played back and re-recorded in a room until the room's resonances overwhelm the words. It is a landmark of electronic and conceptual music.
In briefA short explainer from 2swap on the chaotic behavior of double pendulums. It examines how predictable the system is for some starting conditions and whether closed-form solutions exist.
In briefA talk by Eric Weinstein on gauge theory and its possible application to economics and inflation. It proposes extending the Wu-Yang dictionary into a geometric tool beyond physics.
In briefA one-minute clip of an Atlas Agena rocket losing pressure on the pad and collapsing. The Atlas relied on tank pressurization for structural integrity, so a simple failure tore it apart.
In briefTop Gear segment in which Hammond and May try to turn a Reliant Robin into a space shuttle. Launching is easy, but landing it safely is the problem.
