It is difficult to keep folding paper in half. The reason for that: there's no paper big enough. The hypothetical though: if you fold paper 103 times, the thickness of it will be larger than the observable universe - which is 93 billion light years.

The average paper thickness is 1/10th of a millimeter (0.0039 inches). Every time you fold paper, you double its thickness.

Folding the paper in half a third time will get you about the thickness of a nail.

Seven folds will be about the thickness of a notebook of 128 pages.

10 folds and the paper will be about the width of a hand.

23 folds will get you to one kilometer—3,280 feet.

30 folds will get you to space. Your paper will be now 100 kilometers high.

Keep folding it. 42 folds will get you to the Moon. With 51 you will burn in the Sun.

If you fold it 81 times, it will be 127,786 light years, or as thick as the Andromeda Galaxy.
