The Black Holes And The World War I

-
    After 10 years the publication of special relativity theory (SRT), Albert Einstein (1879-1955) published the general relativity theory (GRT) in November 1915, a new gravity theory (the most successful theory at that time was the Newton's theory of Universal Gravitation). Einstein himself thought that the field equations couldn't be solved  precisely.




    On that occasion the World War I happened and a German physicist and astronomer who was serving the German army provided the first exact solution to the Einstein fields equations of GRT in the same year. His name? Karl Schwarzschild. The solution formulated by Schwarzschild describes a spherical non-rotating mass, static, non-charged electrically, it's in fact a vacum solution and is usually called the schwarzschild spacetime. 


    Unfortunately Schwarzschild died at age 42 from a disease developed while at Russian front, but his work was fundamental on black holes understanding.
    Looking for references? The reading of the book Biography of Karl Schwarzschild could help.

"Feline Quantum Dilemmas: Schrödinger's Cat and the Cold War of Naps and Espionage"

Have you ever heard of Schrödinger's Cat? It's like the ultimate feline existential crisis mixed with a touch of quantum quirkiness. Picture this: there's a cat inside a sealed box, and until you open it, that cat is simultaneously alive and dead. It's like having a cat that's both plotting world domination and peacefully napping on your couch at the same time. Schrödinger's Cat is the OG of indecisive pets, and every time you check on it, it's either throwing a kitty party or attending its own funeral. Now, let's time-travel for a moment and imagine if Schrödinger's Cat had been around during historical events. What if it had been a secret agent during the Cold War? The CIA would have been like, "We have a top-secret mission for you, Agent Whiskers. You're going to simultaneously spy on the Soviets and enjoy a saucer of milk. Just don't let anyone catch you doing both at the same time." It would have been the purr-fect double age

Did Einstein Win His Nobel Prize For Relativity Theory?

Albert Einstein      Albert Einstein (1879-1955) was probably the most famous scientist who ever lived on this planet, and as famous as he, was his Relativity Theory (Well, at least in the scientific community) : grossly this theory says that gravity is nothing more than the curvature of the space-time (a mathematical identity where the space and time are trated as the same in a four-dimensional manifold). Spacetime Curvature      Although it is his masterpiece, this did not yield a Nobel Prize: the relativity theory is in fact the most accurate theory by the experiments carried out of all times, it predicts gravitational waves, time dilatation, Black Holes.     In 1905, Einstein published four important papers, between these papers there was the start of the special relativity theory in addition to what expl
