A PBS Space Time episode asking what matter, mass, and energy really are, starting with inertial versus gravitational mass and what mass-energy equivalence means.

HN recommends it, and the whole channel, as a clear and deeper-than-usual physics explainer.

@MetricExpansion2022 · in “The Shameful Decline of Scientific American”

Pithy, but I’d actually argue the opposite. As someone who consumes quite a bit of science content on YouTube, it’s actually quite jarring to go back to traditional TV science shows. It feels a lot less information dense and more time-wasting. An interesting example is when Veritasium, who normally does the usual YouTube science content, got some big budget funding for one video [1] and produced it in a style more like what you’d see on TV. It was striking how there was so much filler and dramatization to try to make it interesting, and the whole thing felt dumbed down compared to his usual content, for example [2], which is deeper and relatively information-dense. And there are channels like PBS Spacetime which go far, far beyond anything I’ve ever seen in any media aimed at a general audience [3]. [1] link [2] link [3] ▶ this video

The YouTube channel PBS SpaceTime gives an excellent overview of these same ideas. The presenter is great at making things as simple as possible, but not simpler. ▶ this video link link

"The True Nature of Matter and Mass" - ▶ this video This whole channel will be up your alley, but this video and "The Real Meaning of E=mc^2" one directly answer your question.
