METEOR

Why In News:

Ø  Over the weekend, a dazzling comet fragment illuminated the skies across parts of Spain and Portugal, providing astronomers with a rare display.

Ø  Comets are small solar bodies primarily composed of ice. They follow elliptical orbits around the Sun. They are known for their distinctive appearance and unpredictable appearances in the night sky.






Composition: 

Ø  At the heart of a comet is a solid core called the nucleus, primarily composed of water ice, frozen gasses, dust, and rocky material.

Ø  This nucleus can vary in size from a few kilometers to tens of kilometers in diameter.

Coma:

Ø  As a comet approaches the Sun, the heat causes the nucleus to release gas and dust, forming a glowing cloud around the nucleus called the coma.

Ø  The coma can expand to many thousands of kilometers in size.

Tails:

Ø  Comets are famous for their tails, which are composed of gas and dust particles pushed away from the Sun by the solar wind and radiation pressure.

  Quantum Nonlocality: §   While classical physics assumes locality, the principle of nonlocality is a feature of many interpretations of quantum mechanics. §   Nonlocality describes the apparent ability of objects to instantaneously know about each other’s state, even when separated by large distances (potentially even billions of light years), almost as if the universe at large instantaneously arranges its particles in anticipation of future events. §   This is in direct contravention of the "principle of locality" (or what Einstein called the "principle of local action"), the idea that distant objects cannot have direct influence on one another, and that an object is directly influenced only by its immediate surroundings, an idea on which almost all of physics is predicated. §   Non locality occurs due to the phenomenon of entanglement, whereby particles that interact with each other become permanently correlated, or dependent on each other’s states a...
