Where Do Galaxies Come From?

Thanks to the Space Telescope Science Institute (STScI) and NASA’s James Webb Space Telescope for supporting this video! In particular, thanks to Dan Coe of STScI for taking the time to chat with me about what we do and don’t know about baby galaxies and how they're born.

The last time I was this early the "UK was in the EU" joke was funny

if all I had to do was say "yo" I'd have all the galaxies

The fact that the time scale for Galaxy formation is so much longer than the time scale for a human life just shows how on the cosmic time scale, our entire lives pass in the blink of an eye. I wonder if there are life forms that evolved somewhere in the Universe which can, in fact, live for billions of years, and then personally witness the formations of galaxies.

I was a big gassy baby from what my mother told, but I'm not a galaxy.

I just want to say I really liked that age analogy, it helped me understand the diverse scope of our study of the universe. Analogies in your videos are very helpful!

"Everything was just spread out gas and a LOT of dark matter"

Sounds like the Universe had some really bad Taco Bell.

That little doodle at 0:58 is super adorable

Last time I saw an original awesome comment was.. lol never

[locouk]

It's great using a topical sponsor for your video, it makes sense and held my interest more.

It should not be called invisible matter, like you said it only interacts with the known universe through gravity, it should be called Ethereal Matter.

That was a clever potty joke at 2:24! Well played.
