If you fold a paper in half 103 times it'll get as thick as the Universe

The myth: You can't fold a paper in half more than eight times.* The reality: Given a paper large enough—and enough energy—you can fold it as many times as you want. The problem: If you fold it 103 times, the thickness of your paper will be larger than the observable Universe: 93 billion light-years. Seriously. » 7/19/14 3:15am 7/19/14 3:15am

This is the weirdest engine I have ever seen

According to Duke Engineering, their axial engine is the most efficient and lightest engine you can put in boats, light aircrafts, and generators—the mechanical engine of the (near) future! Maybe.
