The size of the visible universe ...

[Kablooie]

I was wondering if I could visualize the width of the visible universe so I decided to try scaling things down to a more imaginable size.

The visible universe is estimated to be around 93 billion light years in diameter.

So ... if universe was the size of the U.S., i.e. 3000 miles...

at that scale our whole solar system would be little smaller than A SINGLE PROTON.

Hmmm.
Boggles, don't it?

For the calculation I used:
universe diam / solar system diam = 55 trillion
wid of U.S. = 4828,032 meters
wid of US / 55 trillion = 8.8^-8 meters or roughly 1 picometre

1. I found this size comparison...

<snip>
If the Milky Way galaxy (in reality, nearly 600,000 billion miles in diameter) was reduced to the size of a grain of salt, the visible universe would be just over 915 feet wide—about the length of three American football fields. Finally, a size we can picture!

What is lost in this analogy is the sheer mass of the Milky Way galaxy and how much reduction is needed to reach this result. In fact, this manageable cosmic scale would mean we have reduced the universe 3.2 septillion times—or 3.2 trillion trillion times. Our solar system, never mind the Earth, would be smaller than a single hydrogen atom!

Amazing!

3. At the scale I worked out the milky way would be about 1.5 meters

2. ... and it's all we have

The rest is a 99.99999999999999% cold, airless and barren void.

4. of course

the entire universe could be much larger than the visible universe!!

5. According to a calculated estimate...

the entire universe's size may be 10^23 times larger than the size of the observable universe.

That means that if the entire universe was 3000 miles wide, the observable universe would be much, much smaller than one proton.

I'm all boggled out.
