Rich | Size, Distance and Time in the Universe

Tonight we explore the often misrepresented concepts of size, distance, and even time on cosmological scales.

00:00:00 | Intro

00:01:56 | Parallax and distance to the Moon

00:30:36 | Distance to Alpha Centauri if Earth was a marble

00:32:10 | How the Sun's light rays are parallel anywhere on Earth (Earth is 8,000 mi across, Sun is 800,000 miles across but 116x further away at 93,000,000 miles)

00:45:35 | Often-misrepresented aspects of existence (importance of proper scales)

00:54:56 | "To Scale: The Solar System"

01:03:30 | Linking psychology and astronomy: the social environment shaped our ancestor's cognition

01:10:24 | Deeper dive into commonly distorted aspects of existence (history, progress, time, data, society, technology)

01:26:49 | Million vs billion: better understanding the universe across orders of magnitude

01:37:00 | Recipe for making the solar system to scale

01:40:01 | Behind the scenes

01:42:36 | Pyramids to andromeda: my desk pictures as examples of orders of magnitudes across space

01:49:42 | Million vs billion part 2 

01:57:04 | Parallax and distance to the Moon part 2

02:02:11 | The slow and very impressive accumulation of knowledge, the astronomy book

02:08:09 | An example of why misrepresentation confuses me

02:11:34 | Beginning our solar system

02:31:21 | Taking our measurements of the planets

02:37:29 | Assembling our mr pencil compass

02:46:04 | Drawing the inner solar system to scale

03:04:56 | Our baseball-field model of the inner solar system

03:06:03 | An overtired baby giving grandma a hard time

03:06:51 | Comparing Earth, Mars and the Sun's mass and diameters

03:12:40 | Completing the solar system model (on my desk and on the baseball field)
