What if you fall into a black hole?

After getting bored from you lectures, assignments and exams, it's a good idea to go out for a spacewalk. Isn't it?😄 Oh wait! Jumping into a black hole seems to be a better one. Have you ever imagined the situation into a black hole ? What would happen if you enter into it? The reality might be weirder than your expectations. Well, a black hole is that cosmic mystery which may tear apart all the physical laws into pieces. So, you might have to think out of the box. Before entering into the black hole you have to pass the accretion disk which is too hot to be imagined, spitting out Hawking Radiation,  and finally the event horizon. Suppose, anyhow, you have succeeded in overcoming these nightmares, what's next?  There are the opinions of a few intellectuals about the further possibilities: 1. If you were to take a jump into a black hole, your body would most closely resemble "the toothpaste being pushed out of a tube," said Charles Liu, an astrophysi...

Birth of the Universe

We all are living in a world full of interesting facts and mind blowing stories, and for many of us, one of the most questionable statement is the -"CREATION OF THE UNIVERSE". We live in a beautiful blue planet, earth but why are we here? Why is this so? Why the universe is in the way that it is?? Almost every religions believe that the god, a super power led to creation of us. Lord Krishna has the whole universe in his mouth, African god 'Mbombo' vomited the universe and there are infinitely many never-ending stories about God all over the planet but all are not acceptable. Different stories across the world lead to the two theories explaining the creation of the Universe: 1) Steady State Theory 2) Big Bang Theory Steady-state Theory Some scholars believe in the Steady State Theory. According to this theory, Universe was always the same. It has neither the beginning nor the end. This theory insists on the constant density of the universe. As we kno...

The concept of Black Hole

Don't be fooled by its name. A black hole is not really a hole as its name suggests. Before diving into the topic let's first be familiar with a few terms. Image of a Black Hole Escape velocity - The lowest velocity with which when an object is thrown from any cosmic body [planets, stars etc] escapes or moves out of its gravitational pull. The escape velocity of the Earth is 11.2 Km/s. Event Horizon - The boundary after which no light or other radiation can move out after striking a black hole. Light cant escape out completely from the pull of a black hole but it does come to a certain limit, that's event horizon of a black hole. A Black Hole is a super dense, massive object with an infinitesimally small volume having escape velocity higher than the velocity of light. And nothing can move faster than light so, nothing can escape out of a black hole. This is the reason it appears completely dark because even light can't reflect back from it. Think of a star...

Aditya L1, after Moon India's all set for the Sun

After the successful launch of chandrayan-2 ISRO is planning to cement its another pillar in the area of Aerospace. India is setting its foot on the Moon, then why leave the Life-giver, the Sun unexplored. Yes, you heard it right India is planning a new mission to study the Sun. The spacecraft named, " Aditya-L1 " (Aditya means the Sun)  has been chosen for this purpose. The mission will probably be started by the end of 2020. Things you must know about Aditya L1. It was originally named Aditya-1, which was made to carry just one payload, VELC (Visible Emision Line Coronogaph). Aditya-1 was a 400 kg satellite scheduled to be launched at 800 km from earth surface in low earth orbit. Later it was realized that if it is launched at " Lagarangian point ", it will be fee from any hinderance e.g. eclipse. Then the mission name was named Aditya L1 mission . [Lagarangian point is a point between earth and sun where the satellite will lie stably rel...
