Is it true that if you fold a piece of paper 42 times it will reach the moon?
Reality: Given a paper large enough—and enough energy—you can fold it as many times as you want . Problem: If you fold it 103 times (only if you could ) , the thickness of your paper will be larger than the observable Universe: 93 billion light-years. Yes,on folding the paper 42 times ,it would reach the moon.
How big would a paper be if you folded it 100 times?
With just over 100 folds, the thickness of the paper would be equal to 93 billion light-years. The reason for this is exponential growth. Here’s how the thickness of the paper would grow due to exponential growth. The average paper thickness in 1/10th of a millimeter (0.0039 inches.)
What is the maximum times a paper can fold?
The commonly accepted wisdom is that you can’t fold a single sheet of paper in half more than seven times. The problem with folding paper in half multiple times is that the paper’s surface area decreases by half with each fold.
Is it impossible to fold a paper 8 times?
Trying to fold an ordinary sheet of A4 paper suggests that even eight times is impossible: the number of layers doubles each time, and the paper rapidly gets too thick and too small to fold. Such ‘geometric growth’ effects are dramatic: in theory, 26 folds would make the paper thicker than the height of Mount Everest.
Can you fold a paper 103 times?
If you fold an A4 sheet of paper 103 times its thickness will roughly be the size of the Universe. Turns out, according to Dr Karl Kruszelnicki, if you do this 103 times the sheet’s thickness will be larger than the observable Universe: 93 billion light-years.
Can you fold a paper more than 7 times?
Yes, absolutely. A piece of paper can, in fact, be folded more than 7 times. It has been done many times in many places all around the world. It’s just that the people who accomplished the feat used a lot of paper!
What happens if you fold a piece of paper 400 times?
A paper will torn as it is not very elastic. On folding it so many times, it’s thickness is gonna be astronomical. It is not possible to get a paper huge enough so that it can be folded so many times.
Why can paper only be folded 7 times?
It’s commonly accepted that you cannot fold a single sheet of paper in half more than 7 times, no matter what paper finish, size, or basis weight you’re using, for two main reasons: Every time you fold your sheet, you reduce your total surface area by half, so eventually you simply run out of surface area to fold.
What if we fold a paper 50 times?
In fact, if you had a sheet of paper, and folded it in half 50 times, how thick would it be? The answer is about 100 million kilometres, which is about two thirds of the distance between the Sun and the Earth.
How thick is a piece of paper when folded in half?
“The first time you fold it in half, it becomes 150 mm long and 0.1 mm thick. The second fold takes it to 75 mm long and 0.2 mm thick. By the eighth fold (if you can get there), you have a blob of paper 1.25 mm long, but 12.8 mm thick.
What is the dimension of 400 folds of paper?
For 1 fold of paper is same as division with 2. For 2 folds is same as division with 4. So after 400 folds, its dimension becomes = 1250 micrometer², which is much tinier than human fine motor skills. So it’s practically impossible, by human hands.
What happens if you fold a piece of paper 103 times?
But oops, there is a problem: if you fold the paper 103 times, the thickness of this ream of paper will exceed the known size of a universe, which is 93 billion light-years. Seriously, how can a paper of 1/10 millimeter thickness become bigger than the universe?
How many kilometers are in 42 folds of paper?
The formula for finding out how many of something you’ll have after doubling it N number of times is as follows where O is the original number (or size in our case). A standard sheet of paper is about 0.1 mm so 42 folds would give us this: That’s 440 billion millimeters, or 439,804 kilometers.
