How did the Milky Way get its shape - Scott Hershberger

Rating: 4.0; Vote: 1
Explore the ever-evolving structure of the Milky Way galaxy, and find out how it got its spiral shape. -- Thirteen billion years ago, the gas and dust particles that eventually became our Milky Way were whizzing around in every direction. Despite the wild motion of its parts, the galaxy as a whole was rotating about an axis. So why did the Milky Way, like most galaxies, become flat, and not spherical like stars and planets Scott Hershberger explores the ever-evolving structure of our galaxy.

I greatly appreciate how this was explained, as complex concepts such as Space is challenging for my poor banana brain hahah.
So, if our Milky Way and Andromeda merge and such, assuming that life (flora and/or fauna, microbio, anything etc) is still existing at that point, what happens
Will it impact the gravity of the planets Or change their orbit trajectory around the Sun
I am just genuinely curious: -)

Imagine how easier is to get from a planet to another in the center of the milky wave. Maybe there its easier to create extraterrestial life. Im thinking about this thanks to the density waves, closer to the center they are stronger if im not wrong. Anyway, im no expert, just trying to have a talk about it: D

When most dinosaurs went extinct
I know it isn't the focus of the episode (which is very well done, but I'm ecstatic that birds being dinosaurs is more common knowledge now.

the person conceptualising these animations is doing a fantastic job. i can imagine it is very difficult to come up with engaging storyboards for complex but short video topics

I don’t understand it. I hear only words that seem Unsubstantiated themselves: like angular momentum. What does that mean in the environment of our solarsystem

This video is inaccurate. Our galaxy looks more like a Pringle's potatoe chip with the surface curved up along the edges. Our galazy is not flat.

Astrophysics has always been a head scratcher for me. Guess there’s some questions that will remain a mystery for me
reply

Yeah, right. everyone knows it's because of Spiral Power, the power of evolution! As proven by Simon the Digger.
