If you are only using this for sleep, you're going to miss out on the most important galactic information known to mankind. This answers so much of the things I think about, and it does so in a graphic format where I can actually imagine the scales of things I never could before. Thank you for this video, Jason Kendall! Oh, and by the way, this was done in 2018. We have since taken an actual picture of the SMBH in the center of our galaxy, or at least the accretion disk that proves Einstein's theory about black holes.

This is wonderful to watch...feels like I'm in school at my favorite class with my best teacher! I recall the 8 year old me being asked what I wanted to be when i grew up ,by my grade 3 teacher "A scientist"...was my reply without hesitation. That never happened, but here I am ,62 years later, just as in awe now as i was then. Thank you so much for giving this old man such an enjoyable viewing experience!

[@dima76]

What do you mean "it never happened"? Being a SCIENTIST is about being TRUE, being OPEN, being brutally FACTUAL, and - obviously - being CURIOUS! NOT about getting degrees, writing papers and making academic careers - all that is so so secondary! What is living if not doing RESEARCH? I bet you are smarter and practically more useful and helpful than 99% of the new University Graduates in WHATEVER field : )) Sounded to me like you kept true to the essence of what BEING the scientist IS, and at 70 years old still have the sense of awe and wonder when learning new things about the Universe AND a sense of simple, humble human appreciation to find the few minutes for thanking the author - YOU ARE a SCIENTIST, SIR, pure and simple, let all these diploma-waving ignoramuses know! :))

2:07 Questions about "1) Redshift": 1. All celestial bodies exibiting redshift, and thus moving away (from our perspective), are bodies situated milions/billions of lightyears away. Thus the redshift we see today happened millions/billions of years ago. Thus the observation we make is no longer up-to-date by millions of years. Are we sure they are still redshifting or are they blueshifting bouncing back, but that light has not traveled back reaching us yet? 2. If our perspective is not the center of where celestial objects are redshifting from, moving away from us, is it logical to expect the same redshift movement everywhere? That would be rather a coincidence.

Hey jason, I doubt you will even get to read this because I imagine you are extremely busy but, I've been watching all of your videos over the past few months and I felt compelled to leave ya a comment. Your videos are so I'm depth and I just love gaining all of this knowledge from your videos. My daughter has now begun to watch them she is 12 and she sticks to the iPad like glue watching your vids!! Woo keep it up man your amazing, and thanks again from the Taylor family!!!

[@JasonKendallAstronomer]

That’s great! These videos weren’t made with 12-year-olds in mind. But if she is into them, and really likes talking about them, find all the STEM resources you can and get them to her. School resources won’t be enough. I took college classes proper in 8th grade and was fully enrolled at university before 9th grade. I graduated high school with half a computer science major done. I ended up with an excellent career. I still went to and finished high school, I just had permission from the high school to take classes that were not currently offered. If she is great at math, then have her follow the path of my mother who dropped out of high school to go to college and become the youngest graduate student at Harvard at 19.

I remember what the milky way looked like in the early 60's from Maui Hawaii. I lived in a small town by the sea . It was quite beautiful as there were practically no lights at that time. Especially during the new moon phase.

[@JasonKendallAstronomer]

Sadly, Cole those days are gone. Perhaps one day again.

[@cole6499]

[@Stroke-it-2-Handed]

[@shananagans5]

No doubt. We used to have a boat on Elephant Butte (southern New Mexico) and the views at night were amazing. Not perfect but it was remote enough to get amazing views.

[@warpdriveby]

I've only been a visitor, but I have gotten to see the night sky from the summits of Mauna Kea and Halealala, both views were so dark and clear that it took me more than an hour to re adjust to the constellations, because for the most part, I could barely tell which one I was seeing. There were so many more stars visible, and they appeared so much more uniform in brightness that I struggled to find even the most obvious landmarks otber than the Milky Way.

[@Darthaurelius]

Who would have thought 20 years ago watching you play baseball for the Pittaburgh Pirates that you had such knowledge of astronomy. I'll never forget I was at the game when you broke your ankle. Still to this day, I can't get the image out of my mind. That injury was right up there with the hit from L.T. that broke J. Theismanns leg.

[@JasonKendallAstronomer]

Very funny story about that.... I was once contacted by a gushing fan of his. I played along but said "please don't let anyone know about this email" (which was different at the time) "but I want to thank you for your support, and I hope you're able to come watch more Pirates games!" I knew that if I impersonated him, I had to do him quite right, and make sure he got all the praise. Same thing applied when someone mistook me for Michael J. Fox on an airplane once.

[@thanez86]

Great lecture series, I really appreciate it. It's helping me big-time to place individual knowledge into a broader picture, meanwhile I'm getting the occasional revelation, such as the spiral arms of a galaxy not being spirals at all really, but are instead individual blobs of gas and stars in their individual orbits that are currently lining up to show us a spiral as we take a snapshot. The spiral is a lie. I found a fun little blooper at 3:14:40 as G350.1-0.3 was called a "galaxy emitting cluster", hehe.

[@JasonKendallAstronomer]

Thanks for the blooper find. When I get around to remastering this video, I'm sure I'll fix that. And actually, the spiral isn't a "lie", it is what we see if you aggregate the view. That is similar to saying that a cloud in the sky is a lie because it's an aggregate of water droplets. Or a dog is a lie because it's really a collection of diverse cells, most of which are non-dog bacteria.

[@thanez86]

@@JasonKendallAstronomer True, I was being flippant with the lie thing. That's what happens without a /s tag :P

Sorry for my ignorance, but i have a question. In the image at 1:21:29 taken by ESA's Planck, the background shows something like the lines of an electromagnetic field, what is it?

[@JasonKendallAstronomer]

That image specifically shows the microwave light emission due carbon monoxide. It’s a simple molecule that forms easily and is a tracer for hydrogen gas clouds. Here, Planck is trying to map it to remove it from their primary goal of seeing the cosmic microwave background.

I heard this term cosmology before, but in a religious context, like Jewish Cosmology, or Hindu Cosmology for example. What the relationship is, if any, I'm still trying to understand.

[@JasonKendallAstronomer]

Cosmology is the study of the entire universe. It used to be the purview of religions, which tried to explain Where It All Came From. But now, we understand so much more. It is now a precision science. Religions still give each their own human-centric interpretation of “Why Was This Made For Me”, and “What Is It All For”? Science seeks to understand the reasons for the natural phenomena that are in abundance. We now have the tools to understand how the universe has changed and grown from the very earliest times. Scientists debate and research the boundary points of knowledge, not resting on or aiming to reinforce one final story, in the manner of a religion. The goal of science is to offer explanations to what’s observed, and see if they fit and if they fruitfully lead to more questions.

Famous science fiction, notably Star Trek, have a theory of convergent evolution to explain why all of the aliens look human/humanoid. It was a little handwaved because they couldn't make good looking ALIEN aliens back then. You may also be interested in Steven wolfram's computational physics research, where the evidence is pointing to physics being this way because we observe them this way, and if you get far enough away physics may actually work differently.
