Now here’s a film about gear ratios, made in LEGO

That's insane! How many years will it take???????

Theres believed to be about 10^80 atoms in the known observable universe... a googol is 10^100

You wouldn't perceive any movement of the final gear within a human lifetime.

If you assumed the input is running at 1000rpm, then it would take 1x10^97 minutes to complete 1 rotation of the final gear.

1 year is 60x24x365 minutes (525,600 minutes)

So it would take 1.9x10^91 years to complete a single revolution of the output... or about 4.75x10^81 times the age of the earth

I knew that.......

:rolleyes:

Also 'googol' was the answer to the final question in Who Wants to be a Millionaire in the famous 'coughing' episode. Good quiz question that.

Reading that was like listening to white noise!! Lol
 
And a googolplex is 1x10^googol

To write that number down would take around 10^94 average sized books. Which combined would weigh significantly more than the total mass of the entire observable universe...

Or if you were to handwrite it it would take about 1.5x10^91 years, or 1.1x10^82 times the age of the universe....
 
And if you really want to boggle your mind, check out grahams number - which is so large that it couldn't be physically contained within the known universe, but it can be written in a specific notation and the final digits are known.

It's still not the largest computed number, but its getting to the limits of what most people can comprehend in terms of scale.
