Eli5 The scale of 18 quintillion

626 views

I recently got into no man’s sky and heard the estimated number of planets (as above) I was floored but felt it’s larger than I’m grasping it and even larger than the way I explain it to others.

I recall from a tiktok or something that if everyone in the world played the game and found a planet 24/7, 365.2425 days, it would take approx 15000 years to find every single planet

Edit: these analogies are super helpful, thank you so much!

Is my time scale accurate also?

Assuming a human lives to 100 years they will live for 3,155,695,200 seconds.

Assuming the earth has 7 billion people who will live for those 100 years, that will be 22,089,866,000,000,000,000 seconds.

That number is 22 quintillion.

18 quintillion seconds is longer than the universe has existed.

If you were to travel 18 quintillion centimeters that would be 1,900,000 million lightyears. That is about 20 milky way galaxies edge to edge.
