How to yo-yo without a string attached… So many crazy tricks and the science that makes it possible.
‘Cymatics’ is the science of visualising audio frequencies. All of the experiments are real.
We already know that water can have three states of matter: solid, liquid and gas. But scientists at the Oak Ridge National Lab (ORNL) have discovered that when it’s put under extreme pressure in small spaces, the life-giving liquid can exhibit a strange fourth state known as tunnelling.
Why is there something rather than nothing? Why does so much interesting stuff exist in the universe? Particle physicist Harry Cliff works on the Large Hadron Collider at CERN, and he has some potentially bad news for people who seek answers to these questions.
Most of us already know that darkness is the absence of light, and that light travels at the fastest speed possible for a physical object. In short, this means that, the moment that light leaves, darkness returns. In this respect, darkness has the same speed as light. However, in some instances, darkness actually moves faster than light.
