3 Things We Still Don't Understand About the Milky Way

We have been studying our home galaxy for years, but even though astronomy has come a long way, there is still a lot we don't know about the Milky Way.

She's so goofy in the coolest, mommiest, teachery sense. This is a complement!

[europademon]

Unfortunately Mr. Way, it looks like you have a sprain in one of your filaments. Any recent collisions, maybe a dwarf galaxy or two, you might not have noticed?

[losttribe]

Just so everyone knows; I'm galacto-intolerant so I can't have any galactoseismology.

It is shameful that only 72% of people answered that question about the dominant source of mass in our solar system correctly.

[jeremyleyland]

5:04 really? 28% of people got that one wrong? Really?

I always love her enthusiasm. (How can you not be excited about this stuff?) And on the shallow side, I also love her hair!

[navsingh]

Very informational. Keep up the good work 🙂
I love this channel, lot of respect and love from India ✌🏻

I’ve realized in researching astronomy that when astronomers find something moving how they they wouldn’t expect, the first thing they always think of is “did this thing get hit by another thing”. Why so much colliding

4:09 As an aside, now I want to take my kid to story time at the library when Caitlin is reading on the Magic Storytime Carpet. Hank would probably be good with silly voices, too. (Pretty sure Reid would make the kids cry with some gruff, scary voice, though.)

And I'm lactose intolerant so I approve of the Monkey Way instead.

I want to know how come our galaxy, and many other spiral galaxies, have that bar structure in their centers?

[carbon_no]

The “high-velocity clouds” were formed because a “mommy velocity cloud” and a “daddy velocity cloud” called the intergalactic stork to order up a fledgling cloud. Then upon delivery they spiked the younger velocity cloud with an unknown number of shots of caffeine and espresso!

That sudden dramatic description at about the 4-minute mark tho.. 😂😂😂😂😂

Good one

[guillaumelafleche]

One hundred million years? Sadly, at the current rate, we'll have destroyed our only home and killed each other long before that, because we're so intelligent (read arrogant).

[saumyagaur]

I love this woman! How excited she gets by astronomy!

[Kaylad]

I miss listening to Caitlin explain cool stuff on HFS. :'(

[Dyslexic-Artist-Theory-on-Time]

Good info!!! Why don’t you make a video on the alternative theories about the Universe on YouTube this would be interesting and good for the YouTube community!!!

[MuadDib]

Caitlin has decreed!
We now live in the Monkey Way. I welcome this unexpected change away from the confection based name we used to enjoy.

Why use Brilliant when you can use Quora for free?

[lancelobato]

did she said "...that formed the MONKEY WAY" at
