If you take a couple of quarters to represent the Milky Way and Andromeda galaxies,
how far away would the two quarters be from each other?
Various Googling suggests that the distance to the Andromeda galaxy is about 25 times the diameter of the Milky Way: (2.5 million LY vs 100,000 LY). So that’s around 2 ft.
Contrast that to this proportion: if our Solar System were the size of a quarter, the Milky Way galaxy would be the size of the continental United States. Each quarter would be thousands of feet apart. This is why galaxies routinely collide but individual stars don’t.
And, depending on estimates, you’re looking at about $75,000,000,000 USD in quarters spread across the United States.
Lets get to it, these quarters aren’t gonna roll themselves…
Nit: Andromeda is about twice as large as the Milky Way (220 kly to 120 kly), so it’s actually closer to a dime and a fifty cent piece.
Nitpick: “Wrap” themselves
