I can't help but notice that at the galactic scale, the journey of the sun is so short-lived. If the galactic year is 230 million and the sun is roughly 5 billion year old, that means the sun is only at its 22nd orbit around the center of the galaxy. Given that the sun has 5 billion more years before turning into a white a dwarf, its whole journey as shining star would last 44 galactic years... assuming the sun doesn't run into another star in the next 5 billion years. Also, great episode and thank you for your hard work.

I can't believe how well done these videos are, and they are free. I'm so grateful.

Surely one of the pinnacles of wisdom and science is the ability to interpret and break-down complex information into everyday terms for those without years of study to appreciate and understand with a curiosity to know more. Great video.

As an old git who has had a life-long layman's interest in such subjects, it's still very enjoyable to learn more about such, even at a fundamental level that helps stitch together other things I've learned so that I get an even greater understanding/appreciation of the bigger picture.... and PBS serves up those juicy morsels with impressive regularity.

I was literally trying to envision the path through the universe the other day and I just couldn't get past what it might look like based on just our galaxy, let alone everything else around us

I love the little “this is what I think” in the outro. That kind of thing just feels so refreshing to my brain after trying to understand all the science of space-time.

Monty Python explained all of this back in 1983: "We're thirty thousand light years from galactic central point We go 'round every two hundred million years And our galaxy is only one of millions of billions In this amazing and expanding universe"
