Black Holes are among the strangest things in the universe. These cosmic monsters are incredibly massive, but cover only a small region. Classical physics fails to explain what happens inside a black hole. Einstein’s theory of relativity works well inside a black hole but breaks down at its center. It is commonly believed that a […]Read More Rotating Supermassive Black Holes could act as portals to another universes
Einstein’s Theory of Relativity forbids ordinary matter from ever reaching the speed of light, as it would require infinite energy. You might have heard of ‘warp drive’ in the science fiction series Star Trek. Warp drive is a hypothetical spacecraft propulsion system that can travel faster than light. A warp drive spaceship could travel faster than […]Read More Warp Drive engines might help us travel ‘Faster than light’ one day
Black holes bend space-time so abruptly that even light finds it difficult to escape their gravitational pull. Nobody knows what happens at the center of a black hole because the known laws of physics break down at the singularity. This puts them among the strangest known objects in the universe. But, mathematically speaking, a black […]Read More How fast do black holes spin?
Whatever we know about black holes comes from the equations and theories put forward by physicists like Albert Einstein, Stephen Hawking and others. A long standing goal in astrophysics is to directly observe the immediate surroundings of a black hole and test whether the observations match with the predictions. The Event Horizon Telescope (EHT) project […]Read More Six Amazing Facts about the ‘First Image of a Black Hole’
The concept of gravity was introduced by Issac Newton in the year 1687 AD. Newton described gravity as the force of attraction between objects having mass. Albert Einstein drastically changed this view of gravity when he published his famous general theory of relativity in the year 1916. According to general relativity, gravity is not just […]Read More Why does gravity travel across dimensions?
Time travel has always been a part of science fiction movies. Imagine going back in time to see the dinosaurs or traveling to the future to witness the Milky Way-Andromeda collision! Einstein’s Theory of Relativity tells us how ‘speed’ and ‘gravity’ affect time. Time slows down significantly around massive objects like black holes, neutron stars, […]Read More 5 ways to travel back in time
‘Theory of Relativity’ is a generalized term used for two different classes of theories given by Albert Einstein namely special relativity and general relativity. General relativity was originally published by Albert Einstein in the year 1915. Before general relativity, it was believed that gravity is a “force” which acts between objects that have mass. However, […]Read More Theory of Relativity explained in simple words
