Introduction For a very long time, it was thought that a black hole only absorbs radiations but this view was changed when Stephen Hawking showed in one of his papers in 1974 that a black hole also emits a special kind of radiation and these emitted radiation results in the black hole slowly losing its mass and eventually evaporates. Now the most obvious question is […]
ARE WE IN A SIMULATION?
Back in the early 1970s, Stephen Hawking wrote an astonishing equation which included quantum mechanics, relativity and information. Hawking’s rather simple equation bought us closer to understanding the relationship between quantum physics and black holes. When an object gets closer to a black hole, the tidal forces crush the object. The information (arrangement of particles in some sense) of these objects shatters away completely. But the […]
ABSTRACT NATURE OF TIME
Time has been a long run debating topic for many people in the scientific community. The notion of time has changed over the centuries in the field of physics. At around the Newtonian period, time was considered to be flowing at a constant rate and everything in the universe was considered to experience the same time. But during the phase of the early twentieth century, […]
UNDERSTANDING THE FOURTH DIMENSION
Hey friends! I assure you that this post would be one of the amazing posts by me. It was very fun to review my old notes and to go through some recent developments on this topic and I assure you to answer all your queries through this post. Before initiating the topic, I would request you to throw away all the methodologies and mindsets for […]
EXPERIMENTAL EVIDENCE OF DARK MATTER AND DARK ENERGY
Hello and welcome back! I hope you, must have read my last post on ‘gravitational lensing‘ and would be curious to know what contributed to the extra mass? In today’s post, I will explore the 95.1% of the invisible energy density of our universe and eventually answer the question. All the matter which you see on earth, in the cosmos constitutes only 4.9% of the energy density of our […]
BIG BANG FOR BEGINNERS
In the twentieth century, Hubble telescope showed us the universe is expanding and the expansion is speeding up which was contrary to the belief that it’s slowing down. After the Big Bang, the universe expanded exponentially and that phase is called inflation. Scientists don’t know what caused the inflation and what stopped it but there are many speculative theories out in the scientific community. If we think from […]
