Those are some “dizzying” numbers, so let’s think about them another way…
For this timeline to show the actual entirety of everything that EVER happened on the planet Earth, the timeline would have to be 181,500 miles long. That’s long enough to wrap around the Earth more than 7 times!
And to show all of time since the Big Bang, the timeline would have to be 544,500 miles long, which would be long enough to wrap around the Earth nearly 22 times, or to put it another way, would be long enough to stretch from the moon and back again, with plenty left over.
