This is actually the first time I've really been convinced that dark matter really is a thing (even if we don't know what it is. Thank you so much Katie for making it so much easier to understand after 15 years!
I went to university for physics, so I've always been skeptical (in the actual science way, but never got to the point where I could evaluate the scientific papers and the state of research. I can finally put to bed the mental noise of wondering whether dark matter is too manipulable a solution

I read and looked into a story of a particle going through a computer, changing a bit, and causing a game to teleport the character.
A guy was playing Mario 64, and a particle (I forget which while typing this) passed through his PC at a specific angle that pushed a bit to the next number.
Is that an example of You'll only interact with a neutrino once
We are constantly being bombarded, but only once in a lifetime does it interact with something on the way through.

Fun fact, positron emission tomography, commonly known as a PET scan, uses the 511 KEV annihilation of antimatter generated by the anthropogenic technetium 99 metastable as well as a number of other radioactive elements to map the inner workings of living processes and give us diagnostics information that previous generations could only have dreamed of in a full-on Star Trek sort of way.

I watch this podcast 10% to learn new stuff (I double majored in Physics, and _loved_ astronomy, so I have a cursory understand of what Dr. Mack is explaining, 30% to feel moved as John learns new stuff, and 60% to hear the amazing ways John Green will turn the wonder of understanding our place in the universe into a SEGUE TO A COMMERCIAL FOR LIFE INSURANCE. 10/10 no notes

Alright, I have to know. When she described a spiral galaxy as a disc of visible matter embedded in a sphere of dark matter, did anyone else picture the end of the first Men in Black movie, where the cosmic being is playing marbles with galaxies (They may have been universes, not galaxies. It's been a long time since I last watched that movie)

I am so loving this series. It is so blissfully matter of fact. It shows what we have done and learned and are doing and learning.
Oddly enough I knew about the ship steel as I once visited a whole body counter that had to be shielded with that same ship metal. It’s just all so damned neat.

Thank so much for bringing us such a beautiful blend of human awe & angst with kick ass science. This is such a wild and wonderful series and I loved this episode particularly. I feel sure that the giants who came before you both will be happy to have you on their shoulders telling the stories!

Hmm. Could the phenomena we observe with galaxies be caused by unidentified curvature of space time
Like. Maybe galaxies exist where they do and function the way do because space time is curved differently there

I would love to listen to the Dr. Mack 5 hour version of this episode! I am fascinated by dark matter and our search for it and will listen to as much as Dr. Mack is willing to share which sounds like a lot!

I think Einstein was right in the fact that space is made out of the same thing matter is. In that regard, what we attribute to dark matter is actually just space itself being clumped up just as matter does.

Yes! So glad this show is continuing. I wasn't sure if it was recorded on advance and was afraid it was canceled due to John's hiatus.
I hope your rest is going well John, you deserve it.

Just marvelous! How cool it must be to do this as a career- if I were young, I'd be an astrophysicist & the math, well, that was always the problem for me, but I just love this hard stuff.

I feel like there's a good chance that this series of videos will be as influential to some future young scientists as the cosmos series with Carl Sagan was for some previous generations

It was episode 6 when I noticed 2 people sitting in the foreground looking at the stars. Of course, most of the time, I am just listening or watching the subtitles or the pulsar pulsing.

The chances of neutrinos interacting with your body are a trillion to one they say
The chances of neutrinooooooooos interacting with your body are a trillion to one
Yet still they come

Seriously, whoever thought about promoting life insurance with this series need a raise immediately. Wow, this is really heavy existential dread. let's sell insurance with it!

First off, I really, really love this series. But I think I need to watch some make-up tutorial or puppy video to come back to myself again, now.

Did everyone pause at the end of the bullet cluster explanation, study the picture, then rewind the explanation and go, Ohh, I get it!

Dear Subtitle team. at 52 minutes Katie talks about 'parity', and is incorrectly subbed as 'parody'. No shade, I love all the hard work
