The Milky Way galaxy is relatively calm by the destructive standards of the rest of the Universe, and compared to its own very violent past. But just recently we discovered that its violent past was much more recent than we thought - and could even happen again.

It just occurred to me the role Matt (and others like him) serve. Imagine if (or remember when) Matt wasn't on YouTube and we had to be told about these things from.... journalists. Those brilliant people who accurately convey the latest developments in various fields. Like Carl Sagan and Neil Tyson, Matt is in a prestigious line of knowledgeable scientists with the skill of communication. He bridges the gap between working scientists and lay people like us. He's our "journalist" with his finger on the pulse of the latest goings on. And he KNOWS WHAT HE'S TALKING ABOUT. *I* may not always know what he's talking about, but I can have faith that HE does. Unlike when the news tries to tell us something. Thank you Matt!

"Which actually makes Earth a Taurus, which explains so much."

This is why I like this channel. Never too serious they can't enjoy the funny side of thing. Always so detailed your head gains some angular momentum.

Brilliant!

"Whatever is happening here on earth, the universe remains awesome!"

I needed that...

"Whatever is happening here on Earth, the Universe remains awesome."

Thank you.

"...has been relatively calm, for as long as we've been observing it."
That made me chuckle, considering astronomical time-scales.

Consider this: If Sagittarius A got active again 10, 000 years ago, we'd still be 16, 000 years away from realizing. Unless we develop superluminal means of observation or travel first, that is.

Me: I'm passionate about the space and science. I love how the language of math can elegantly describe the beauty of the Universe.

PBS Space Time: Saggitarius has a snack followed by a burp, to make bubbles.

Okay, my ten minutes are up, time to get back to...

OH COME ON.

Thanks for working hard to keep this going even when working at home! Greatly appreciated.

Thanks for the second video in a row that doesn’t hurt my brain to try to understand

”Galactic Core”

*painful Mass Effect flashbacks*

"The Mandalorian famously pioneered the use of video walls as backdrops to replace rear projection and chromakey. Now that ILM's done all that hard"development work, the tech is spreading to other TV shows. Clearly, to allow you to properly appear standing in front of the floating spacetime effect and keep up with the competition, PBS is obligated to buy you a wall-sized video display for your apartment.


I have spoken.

It always amazes me how we can explore the center of a star or some of the most extreme places in the universe by using instruments while STAYING HOME :). So even in a pandemic we can still explore the universe.

Number 3: Why didn't they call it a "Hubble bubble?" Seems like they missed an opportunity.

[eager]

Paused this in the first minute, just to acknowledge the pure brilliancy in ”whatever happens here on Earth, the Universe remains awesome”. Thank you!

[CloudsGirl]

"Whatever's happening here on Earth, the universe remains awesome."

...Have truer words ever been spoken?

[aniaugus]

10:55 - That one dish looking other way: Nope, not gonna look xD

[peterc]

Thank you! Your work end effort for educating and entertaining us is much appreciated in this time! Greetings from Prague, Czech Republic.

[dwigtschrude]

Thank you Matt and everyone at PBS Digital Studios for keeping space time going right now! Although according to the anthropic principle we can only be living in a universe where space time persists through a global pandemic

Whats an astrophysicists favorite candy?
