Please note that this website is currently a work in progress! Lots of interesting data and statistics to come.
Cosmos should be compulsory viewing in every school worldwide. Such a fantastic series
This video gave me a theory about the movie Arrival that the heptapods came from the fourth dimension and the 12 heptapods was actually 1 heptapods projection into our three dimensions. The main thing that made me think this might be true was the fact that they each had 90min time slots, every 18 hours, to enter the pod. That's 1/12. So each country basically took turns going into the same heptapod, talking to the same aliens. The heptapods all arrived at the same time, and left at the same time, because it was just one heptapod projecting into our world. Also coincidentally (or not), a cube has 12 edges, so based on Sagan's example of using a cube, that could be why there were 12 heptapods.
This is one of my favorite segments in cosmos, alongside the one explaining the doppler effect. I have a playlist of the entire show that I fall asleep to every night.

The entire series, I cannot even begin to recommend it enough. You can also find all of his books as audiobooks on youtube. Most of Pale Blue Dot is even narrated by him.
A 4th dimensional being would be able to see the insides of everything in our dimension same as we can see everything in a 2D image.
Anyone else get a very Matrix Agent Smith vibe from the way he talks. Maybe Hugo based it on Carl or maybe it’s just a little coincidence? Once I heard it, I couldn’t un-hear it.
"Flatland" is a great. A quick read with a bunch of cool thought experiments. Another part that stands out to me is when the main character (a triangle) visits Pointland.
I still don't get it. Can we touch a fourth dimension or is it just hypothetical?
Carl Sagan is one of my all time heroes. What a great man.
This video has been sitting on my suggested videos list on youtube for a while. Glad this post finally got me to watch it
