BLACKHOLES 🕳️

              


 B4-Blackholes 


In this blog I am going to talk about  holes.
Oh ,don't worry not the holes you were thinking about ,but a space entity that you must have heard of several times.
________________________________
The first question that arises is
WHAT IS A BLACKHOLE ? 🤷🏻‍♂️
They are a region of space-time ( 🌌-🕤) having such a large gravity that no particle ,not even electromagnetic radiation (like light 💡) can escape it. 
Therefore it appears completely dark .They can be compared to black bodies as they absorb all light.
The boundary of blackholes is called event horizon.
________________________________
Hawking Radiation
Earlier scientist and astronomers thought that blackholes are completely black and indistinguishable in space , but the astrophysics genius Stephen Hawking combined the concepts of Theory of general relativity in curved space time and Quantum Physics to predict that blackholes are not completely dark but emit a radiation (from event horizon) whose spectrum is same as a black body whose temperature is inversely proportional to it's mass.
This radiation was named Hawing Radiation.
His predictions were confirmed when the first image of blackhole was captured from the Event Horizon Telescope (EHT) 🔭.

Billionaires and Their Favourite Foods

    Photo Courtesy: Author  B20_ Billionaires and their favourite foods        Recently, I had a strange dream which seemed very real. In my dream I was seated besides Steve Jobs,  Elon Musk,  Bill Gates and Warren Buffet, and all of us were having dinner. Salt Bae and Gordon Ramsay served us the delicious food and we enjoyed the meal. When I woke up it seemed that I was inside a dream,  just like Leonardo Dicaprio was in Inception.     Therefore, I thought that it would be a nice idea to read and write about the favourite foods of some billionaires.     Just wait to know Jeff Bezos' and Steve Jobs' most relished dish. 1. Bill Gates       Bill Gates just loves eating burgers 🍔 , no matter what's inside it. As long it is a burger it's the favourite food of the former Microsoft CEO & Co Founder Bill Gates.
