If you take a piece of paper and rip it in half, stack the pieces together and rip it half again and continue to do that for 50 times how tall would the stack of paper be?
Depends on how thick the paper is and how much space between each sheet of paper. And, as much as I hate to say this, math would be a far easier way to figure it out than ripping up paper.
And if you do it 103 times it'll be larger than the observable universe.
