The Meaning Of Life

Hey everyone, it's been a long time since i have last posted but this is one of the posts that i had to share with you.    Do you ever just sit back and think that if life had been different? If you had been someone else and would have led a more prosperous and tension-free life? I have been there too and while thinking about that, i questioned myself, what is the benifit?    We all take birth, we all die and nobody gains anything out of it. If according to the people, "God" created us then can please anyone explain it to me, Why?       If he created us then he must have a purpose and i don't seem to be completing any task that he has given us. Why did he create us? What does he get out of it?     In Hindu religion it is stated that after 80 crore births as animals, plants or insects, you finally take the form of a human but for what? To study my whole life and then give up trying?     To always be in stress and worry about my future? I didn&

Black Hole : Life - cycle of a star





This is my 4th post about black holes but this is a different story, this post is about how black holes are made under the observation of deep science and astronomical science.

   
            When a giant star like Betelguese, which has the core of a lakh times greater than the sun, is on its death stage it forms a red giant. In a red giant, hydrogen is exhausted and forms thermonuclear energy which would give tremendous amount of heat and light, Its mass also increases. This would happen in every size of star.

              After this, the thermonuclear energy gets exhauted eventually, which results in the sun being so cold that it would be blue in colour. This stage is known as Blue Giant Sun. This is common in every star's life.  

                       This is the most important stage in the life of a star as huge as Betelguese. In this stage the core gets no energy so it starts to pull itself apart or eat itself due to its own gravity. This causes a massive explosion. This results in an empty space between the singularity(i.e- The depleted core) which has tremendous gravity. This stage is known as Black hole


      SPECIAL NOTE-  Our sun will not be a black hole as its size is medium compared to other stars. NASA predicts that the sun will be white dwarf
