Yes
A piece of paper can be split in half several different ways. One can cut it with scissors (horizontally or vertically) tear it, slice it with knife or use a professional cutting machine (like guillotine).
But if you mean cutting the paper in half, thick-wise,
that is a lot more difficult to do. If the paper is regular printer or newspaper thickness, regular household methods won't cut it. For that you need laboratory equipment, especially something that can do cutting on molecular level.
It is generally believed that an A4 piece of paper can be folded in half approximately seven to eight times due to the thickness of the paper increasing with each fold, making it increasingly difficult to fold further.
If you fold a piece of paper in half 50 times, you would get a stack of paper so thick that it would reach the sun and back multiple times, with a thickness much larger than the observable universe. It's a theoretical concept as it exceeds physical limits.
In theory, paper can be folded in half more than 7 times, but it becomes increasingly difficult as the number of folds increases. The thickness of the paper and its size are limiting factors that make it practically impossible to fold a standard piece of paper more than 7-8 times.
If you could physically fold a piece of paper in half 20 times, it would result in 2^20 layers, which is equal to 1,048,576 layers. However, due to physical limitations, it is practically impossible to fold a piece of paper that many times.
To make the loudest paper popper, fold a piece of paper in half lengthwise, then fold it in half again. Hold the paper at one end and quickly flick it to create a loud popping sound. Experiment with different paper sizes and folding techniques to achieve the loudest pop.
The answer depends on the piece of paper. You can cut it in half lengthways: it will still be a piece of paper but its width will be half as large!
The height of a piece of paper folded in half once is half of its original height.
You take 2 square pieces of paper and fold both in half. Cut one halfway down the fold line making a split. Put the uncut piece of paper inside the split and tape where you want it to stop sliding.
Folding the piece of paper does not change the thickness of the piece of paper. However, the thickness of the folded paper would be twice that of the original sheet of paper.
Q. What size is half of an A4 piece of paperA. A5 piece of paper 1/2 of A5 = A6 1/2 of A6 = A7
Take a piece of paper and cut it in half (anywhere will do) and you will have two pieces of paper - and your original piece of paper has changed shape.
Any paper can be folded in half for 6 times.
You can't fold a piece of paper 50 times
It is generally believed that an A4 piece of paper can be folded in half approximately seven to eight times due to the thickness of the paper increasing with each fold, making it increasingly difficult to fold further.
Physical change
Any size sheet of paper can only be folded in half 7 times.
With a pair of scissors. Personally I use my mind to will the paper to cut itself.
