The observable universe is 93 billion light years across.

Well, it's roughly 100 quintillion (10^20) times the size of the Earth.

For comparison, imagine taking this whole 1920 pixel by 1080 pixel video and making

If you were to take each row of one thousand, nine hundred and twenty pixels and string

them all end to end, then shrink that huge distance down to the size of one pixel of

the video, string the new video's pixels out end to end, shrink it all down AGAIN to the

size of one pixel of video, and string the pixels out end to end once more... that one

tiny white pixel represents the earth, and the string of all the pixels all together,

is one tenth of the diameter of the observable universe.
