Scale of the Universe

The most astounding fact… https://www.youtube.com/watch?v=9D05ej8u-gU

Powers of 10 Video https://www.youtube.com/watch?v=qxXf7AJZ73A

Let’s look at some numbers Earth: 12,700,000 meters Jupiter: 170,000,000 meters The sun: 1,400,000,000 meters Earth to sun: 150,000,000,000 meters Milky way: 1,200,000,000,000,000,000,000 meters Observable universe: 930,000,000,000,000,000,000,000,000 meters

Lets visualize some of that…

Add a scale of 10…
