You'd think these guys have gone to tremendous lenghts for nothing. Well, if you count proving a point about fact-checking and scientific veritability as "nothing", that is.

It's not just about the true total length of blood vessels in the human body, mind you:

This is an interesting overview of the origins and characteristics of the Proto-Indo-Europeans, as well as theories regarding how they managed to spread through Europe and Asia. A new theory of the origins of the language released in July 2023 is also discussed and challenged.

This is the original landscape-format version of the short movie Cosmic Eye, designed by astrophysicist Danail Obreschkow. The movie zooms through all well-known scales of the universe from minuscule elementary particles out to the gigantic cosmic web. This project was inspired by a progression of increasingly accurate graphical representations of the scales of the universe, including the classical essay "Cosmic View" by Kees Boeke (1957), the short movie "Cosmic Zoom" by Eva Szasz (1968), and the legendary movie "Powers of Ten" by Charles and Ray Eames (1977). Cosmic Eye takes these historical visualisations to the state-of-the-art using real photographs obtained with modern detectors, telescopes, and microscopes. Other views are renderings of modern computer models. Vector-based blending techniques are used to create a seamless zoom.

Astrophysicists from NANOGrav have announced they've found the gravitational wave background! This is a brand new way to study the universe, so let's go over exactly what this means for humanity!

Have you asked yourselves how bikes stay up? I mean, what's the physics behind this?

It's largely a mystery, meaning it's not yet properly explained, although there might be some clues about how it actually works.

Curiosity Stream does some quite good videos in explaining stuff from scratch. This whole channel is awesome.

I love Chuck Nice. Not just because he makes Neil deGrasse Tyson's podcast much more watchable (listenable?) And he has some good points here. Which he of course presents in his typical funny way. Enjoy watching! I sure did.

Look around you. Where are you? Where is this place you are occupying? Somewhere in a room, maybe in a city on a continent on a planet orbiting a star in a galaxy among billions. But… where is all of that? While this may feel like a daft question, it turns out that the concept of an absolute position is something humans made up.

In a nutshell, the universe is a big bag of space that has things in it. If someone removed all these things, the stars and planets and black holes and dust, there would just be empty space left. In empty space, the concept of having a position loses all meaning. Empty space is uniform, the same everywhere.

And of course it's Terry Pratchett. From The Hogfather. Deep.

Although one third of the population suffers from motion sickness, scientists aren't exactly sure what causes it. Like the common cold, it's a seemingly simple problem that's still without a cure. And if you think it's bad on a long family car ride, imagine being a motion sick astronaut! Rose Eveleth explains what's happening in our bodies when we get the car sick blues.
