If the entire known universe were the size of the earth...

How big would the earth be in it.

The size of an atom?

Depends what you mean by the “entire known universe”. Wikipedia says the diameter of the observable universe is 93 billion light years. Using that number, 93 billion light years divided by 8000 miles is 6.8 x 10[sup]19[/sup]. 8000 miles divided by that number is about 0.2 picometers. That’s about 10 to 100 times smaller than an atom, which is about 3 to 30 picometers.

The smallest atom, Helium, is about 31 pm across.

Whoops, I was off by a factor of 10. I should have said an atom is 30 to 300 pm, and the scaled down earth is 100 to 1000 times smaller than that.

Which makes the mini-Earth much larger than a single atomic nucleus (regardless of type), but much smaller than a single atom (regardless of type) including the “size” of the electron cloud.

The Milky Way, on the other hand, would be surprisingly large - the disk being around 40 feet across.

I would be like a God
Except for the 4 billion other now God-like people running around of course

You’d be a very, very tiny sub-atomic god.

Wait, i dont get to retain my normal size?
Now that’s a deal breaker that is

And I’m wondering who the three billion non-godlike folk would be.

You misread :smiley:

Except for the 4 billion other now God-like people running around of course

The other 3 billion are republicans

Im kidding :slight_smile:

There were 3 billion other non-godlike people running around. [/reddawn]
