Black Hole

 Hello everybody, I am back with another brand new blog. Today's topic is very exciting it's all about what is a ' Black Hole ' many of you must know it, but some don't know but no worries !! Today in this blog I will tell in detail what is a Blackhole.


A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because the matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars black holes can be big or small. Primordial black holes are thought to have formed in the early universe, soon after the big bang. Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space. Scientists think supermassive black holes formed at the same time as the galaxy they are in. This size of the supermassive black hole is related to the size and mass of the galaxy it is in. Albert Einstein first predicted the existence of black holes in 1916, with his general theory of relativity. The term " black hole " was coined many years later in 1967 by American astronomer John Wheeler. After decades of black holes being known only as theoretical objects, the first physical black hole ever discovered was spotted in 1971. If an object or a material is drawn into a black hole they'll undergo a process evocatively called ' Spaghettification '. This is because gravity is so extreme and increasing so rapidly as you approach the black hole that your head and feet would experience drastically different gravitational environments. The Sun will never turn into a black hole because it is not massive enough to explode. But if hypothetically, the Sun suddenly became a black hole with the same mass as it has today, this would not affect the orbits of the planets, because its gravitational influence on the solar system would be the same.

My Favourite Subject Is Math

 Author: Mehvish Khan Hello, my name is Mehvish khan, and today my topic is “my favourite subject Math”. I know you all have a question, that why math is my favourite subject, not other subjects. Math is my favourite subject because in math we have to solve sums like addition, fraction and many more. I like to solve it, and it is so much fun to do it, and one more question you are having that is we all are facing problem in solving math, and I will tell you the shortest method to solve math. When you solve math, pause, think properly and then answer. This was the first thing, and the second thing is to keep your mind fresh, happy and sharp, so your mind will work so you can answer quickly. So I think all the questions are clear, so friends, tell me how did you like my today’s blog so, if you like it, please give me a like and a heart, so we will meet in another blog and thank you very much for reading my blog and see you soon bye-bye.

They have many advantages but the disadvantages are also there, plastic can kill many creatures and it also leads to many other difficulties as well. We will be discussing the disadvantages of it and that are as followed - Plastic is non-degradable and it fills many areas on earth. It chokes many water bodies, sewer systems, and more. Many animals and birds perish because of plastic as they deplete plastic as a diet. Plastic is widely utilized in packing food items that can steer to cancer. It results in many enormous fire cases. When plastic is thawed for molding or when it is burned, it discharges many lethal gase...
