Have you ever marveled at the mesmerizing dance of Newton's cradle, where balls collide and seem to defy gravity, or wondered what happens when objects collide at different speeds? Today, we're diving into the physics of collisions, unraveling the mysteries behind the conservation of momentum and energy, and exploring the fascinating world of elastic and inelastic collisions.
Have you ever wondered what the universe was like in its very first moments? Not just in the distant past, but in the fractions of a second after the Big Bang? Imagine a time when the universe was a trillion degrees hot, filled with a liquid soup of subatomic particles and pure energy. This isn't science fiction; it's the reality that scientists at CERN are striving to understand. Let's dive into the fascinating world of particle physics and the quest to recreate the conditions of the early universe.
