WORM HOLES

Most of us are familiar with the fancy scientific term " Worm hole " through movies or YouTube videos. It's bizarre physics and potential for manipulating " Space " and " Time " is what we are interested in. However, like most scientific phenomena, most of us have a pretty vague or partial understanding about how a wormhole works. For instance, the image posted along with this post is what many of us thinks a wormhole might look like. But in reality, a wormhole, if it exists, would be spherical rather than a circular tunnel . This is because we experience space as a 3 dimensional entity ( 3 D ). Movies like " Interstellar " could shed some light on the appearance of worm holes.A wormhole is also called an " Einstein-Rosen Bridge ". A wormhole visualised in 2-D: Wikipedia A wormhole can be seen as a tunnel having two ends which connects two different points in" Space-Time " (different location,different points in time, or b

SCHRODINGER'S CAT

  Nothing explains the state of " Quantum Superposition " as brilliantly as the Erwin Schrodinger's famous thought experiment :  " The Schrodinger's Cat " .  Although at times regarded as a Paradox, this thought experiment was devised to point out the errors in the Copenhagen Interpretation   of Quantum Mechanics , which suggested that " a particle exists at all states at once until observed ".    In this hypothetical scenario a cat is kept in a sealed chamber along with a Geiger counter ( an instrument for detecting and measuring ionising radiation) a radioactive sample and a bottle of poison. If the Geiger counter detects ionising radiation due to decay of radioactive sample, then the bottle of poison will break and the cat will die. Now Radioactivity is a " Spontaneous"  phenomenon meaning there is only a probability for the sample to undergo decay. Since the chamber is sealed we can't know for sure whether the cat is alive or de

BLACK HOLES

The term " Black Hole " was coined by American astronomer John Wheeler in 1967 but their existence was theorised by Albert Einstein back in 1916 itself. Contrary to most people's beliefs, black holes are not some " Cosmic Vacuum  Cleaners ". That's not how they work. A black hole can be thought of as a place in space where gravity is so strong that even light, the fastest thing in the universe according to Albert Einstein, can't escape its pull. The strong gravity is due to the fact that all of its matter has been crushed to a very little space called a " Singularity ". In order to understand that, we need to look at the formation of black holes. Mainly there are 3 types of black holes: Stellar  Supermassive Intermediate Stellar Black holes:   The most co mmon type of black holes found in the universe so far. As their names indicate, these are formed by stellar death or the death of a massive star. When a massive star burns through the las
