Interesting video, I was always fascinated by the measurement of Astronomical Unit suing Venus transit and read many books on the subject, yet this was clear and precise to the point. Thank you
So, I randomly used Sydney, Australi and Dallas, Texas as locations and I got a cut through the earth distance of about 11,350 km. Compared to the antipodal distance of 12,756 km. But the time of exactly 8 minutes seems too clean.

I still can't believe how we figured all this out, and how much time and collective human effort it all took!
Jeremiah horrocks in 1639 was the first to put forward the transit of Venus to measure the au not Halley.He got a pretty good estimate too.
What if the sun is 2x the distance and 2x the size? Wouldn't you observe the same thing?
