How Cold Can You Go? | 50x50 Science

102K views · 3w ago · 13:02

In the heart of New York City, physicists are making exotic states of quantum matter - states that have possibly never before occurred in the Universe. Today, as part of the 50x50 Science Across America series, Cool Worlds visits the coolest place of them all to see how this happens...

575K views · 1mo ago · 18:40

Go to for a free sample pack with any purchase! There's been a lot of news about a possible detection of a dark matter particle - did we finally just crack one of the grandest challenges in modern science?! Today, we break down what dark matter is, how the search experiment works, and what was found.

AI Has Poisoned Everything

281K views · 1mo ago · 18:32

A video essay and opinion piece on what worries me most about AI. Like so many of the big issues in our lives, it's not a black-and-white good-vs-evil dichotomy. Although it's certainly a powerful and amazing tool in many use cases, something I often use myself with great wonder (e.g. we often use AI to upscale grainy clips), I fear its irresponsible (and perhaps unavoidable) exploitation may push us into an intellectual dark age.

Why Finding Aliens Could Doom Humanity

The "Great Filter" is a pivotal idea in astrobiology. It may very well explain the Fermi Paradox. Today we explore what it is, some candidates for it's cause, and the shocking consequences it implies with respect to our future detections.

We're Finally Unlocking the "Cosmic Shoreline"

225K views · 5mo ago · 18:02

Head to an exoplanet seminar or conference and you'll constantly hear astronomers talking about "the Cosmic Shoreline". But - what the heck is that? Why is it so important? And why is JWST dedicating a huge amount of telescope time to studying it?

Why We Might Live in a "Barely Habitable" Universe

295K views · 12mo ago · 16:10

Intelligent design purports that the Universe was made by a creator - God. One of the arguments often invoked to make this case is that the physical constants of the Universe are (apparently) finely tuned to permit life. But cosmologist Denis Sciama presented a thought-provoking analysis of this line of thought and suggested it might be possible to even test intelligent design. Join us today as we explore this fascinating concept.
