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) 🔭.

These habits can be easily developed. The last habit is the most common , everyone that you can think of while thinking about success has that habit. 1. Wake up early I know that you might have heard it a several times that waking up early is good. Your parents must have urged you to wake up early in the morning and you always thought that what's the point? There is no harm in sleeping a little bit more. I don't care if you are a morning person or a night owl , but waking up early is in itself just "magical".

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. He loves to devour cheeseburgers , veg burgers , hamburgers and now ...

STOCKS

        B7_You must have heard of several terms like stocks,shares etc. and wondered what do they mean . Here's the best blog for you to understand these terms  ________________________________     📉 WHAT ARE STOCKS 📈 ? Well there are several ways to define what are stocks. Stocks  are technically defined as the shares of corporation into which ownership of the corporation or company is divided among the stock/share holders. Most of the people can't understand what does it mean , So, I define stocks/shares simply as a part in a company that is provided for sale by the concerned company to people . ________________________________ For eg. If SpaceX🚀 or Tesla🚗 has provided 100 shares of their  company for sale in the stock market then they are offering people to own 100 parts of their company . If you buy 69 stocks then you own 69 shares out of 100 of the company whose stocks you have bought . ________________________________ ...
