The Zooms
The magnification rate of “Fractal Zoom” is approximately 2.4 times closer per second. I calculated this from information they provide in their video’s description.
The zoom rate of “Powers of Ten” is stated by the narrator as being “10 times further every 10 seconds”. This means a magnification rate of about 1.2589 per second.
I took me a while to work out by what factor I should speed up the “Powers of Ten” video. I also had to do a (very clumsy) cut between the “Picnic to Universe” section and the “Picnic to Atom” section.
