✨Cosmic rays and radioactivity are connected, revealing a weirder, more wonderful universe.
🌌Physicist Paul Dirac unified quantum mechanics and special relativity in his Dirac equation.
⚛️The Dirac equation predicted the existence of antimatter, leading to the understanding of a mirror universe.
🔬The discovery of antimatter and its properties have practical applications in medical imaging.
🔥When matter and antimatter come into contact, they annihilate each other, releasing immense energy.
What are cosmic rays?
—Cosmic rays are high-energy subatomic particles that bombard the Earth from outer space.
What is the Dirac equation?
—The Dirac equation is a mathematical equation that unified quantum mechanics and special relativity.
What is antimatter?
—Antimatter is composed of antiparticles with the same mass as regular matter particles but with opposite properties.
How is antimatter used in medical imaging?
—Antimatter electrons, known as positrons, are used in PET scanners for advanced medical imaging.
What happens when matter and antimatter come into contact?
—When matter and antimatter come into contact, they annihilate each other, releasing a tremendous amount of energy.
00:06In 1912, Austrian scientist Victor Hesse discovered cosmic rays pouring in from outer space and their connection to radioactivity streaming from the interior of atoms.
02:06Physicist Paul Dirac unified quantum mechanics and special relativity in his groundbreaking Dirac equation.
02:43The Dirac equation predicted the existence of antimatter, leading to the possibility of a mirror universe.
12:40Antimatter is routinely created in laboratories and has practical applications in medical imaging, such as PET scanners.
13:31When matter and antimatter come into contact, they annihilate each other, releasing a massive amount of energy.
