Who knew a piece of paper could blow your mind?
Science enthusiasts, that’s who. Because it turns out you can theoretically reach the end of the universe just by folding a plain old sheet.
Clever clogs might argue that it’s impossible to fold a piece of paper more than 12 times – a record currently held by California high school student Britney Gallivan thanks to a 1.2km-long piece of tissue back in 2002.
However, physics nuts might also point out that you’d only need to fold a piece of paper 42 times to create a tower that would reach the moon.

YouTuber Nikola Slavkovic set about explaining the staggering theory in layman’s terms, telling viewers: “Hypothetically speaking, if the average paper thickness is 10th of a millimetre, how many half folds do we have to make so that the final piece of paper is 1km tall? Twenty-three folds.
“How many folds to reach space 100km above us? Thirty folds.
“How many to reach the moon? Forty-two. The sun? Fifty-one.”
Finally he asked: “How many folds would you have to make so that the final piece of paper is 93 billion light-years [long], or the diameter of the observable universe?
“Wait for it... 103 folds.”

Slavkovic went on: “Yeah, I'm surprised, too. But we are not talking about linear growth here – one, two, three, four five, – we are talking about exponential growth.”
We won’t even attempt to explain that term right now. Just enjoy the paper.
