Hybrid Ring Narrows the Range to Find the Clue to Early Universe
A high sensitivity particle physics experiment proposed by IBS scientists can unveil mysterious disappearance of the antimatter at the creation of the universe.
Imagine a baseball pitcher throwing a slide. As the ball travels horizontally through the air, it also moves down because of the effects of the force of gravity, making a shape of curve outwards. Then what would happen if time reverses? Will the ball curve reverse, i.e. inwards, just as the ball is thrown back? If you tape the motion of throwing and play the video backwards, you will see the ball still curves outwards with gravity unaffected by the time reversal. This is an example of so called "symmetry in physics," the concept that properties of particles such as atoms and molecules remain unchanged after being subjected to a variety of symmetry transformations or "operations" – in this case, time reversal.
