Black hole are formed due to the explosion of a big star in a supernova it happens when a star runs out of fuel. A star like our sun will not become a black hole as it is too small to become black hole, it will become white dwarf {if you don't about this you should check my previous blog on ‘stars can die’ like will be down} but what will happen if we crush an object its end limit, lets find it out;

What happens when we crush an object to its end limit? If we find a way to crush all the mass of Boeing A380 to its end limit it will become a black hole with the radius of 3.386 to the power -22 which is very very small, this black hole will last about 1 second or so due to the Hawking radiation. Let's imagine what will happen if we crush our planet to a black hole, what will be the size of our earth? Hmm, it will be the size of a coin but nothing will happen to its gravitational field {as black hole doesn't affect gravitational field}. So if our sun became a black hole it will have the radius of about 3km which is very small compared to our sun. The smallest black hole like XTE J1650500 has the radius of about 12km and has mass of 10 suns. The biggest black hole which is in the middle of our galaxy has the radius of about 12,700,000km and has mass of 4,300,000 suns inside of it. S50014+81 is the biggest black hole in the universe it is 236.7 billion kilometres big and has mass of about 40 billion suns which is incredible.

principals of superposition says that while we are not observing any object, that object goes crazy but when we observe it, it comes to its original position but is it really true, let's find it out; If we randomly shoot marbles which passes through a metal slit to a screen it will make a pattern where some marbles will pass through the slit and hit the screen making a pattern of single line, and if we will add 2nd slit we will see 2 lines.

Now do the same thing but use water, so when water will pass through that 2 slit it will create an interference pattern.

Now again with the same setup use electrons. So when that electron will pass through those slits it will also make an interference pattern like wave but when we try to observe it, it will act completely different it will act like marbles.

 Now you may wonder I'm crazy, no but I'm not it is true. As principal of superposition says that an object has many different positions when we are not looking, in another word, we can say objects act completely differently while we are not looking.

The heaviest object in the universe ‘black hole’. Because of the black hole, we are alive but, we will die if there will be no black hole. In this article, we are going to discuss everything you need to know  about black hole, so let's get right into it; When a big star dies it die in a huge explosion called as supernova after that it becomes a neutron star or a black hole. When we look at a black hole the black part is called event horizon and at the center of the black hole is the singularity. Black holes are black because their gravitational field is too high that even light can't escape. Galaxies are there because of the black hole as black hole are the heaviest object in the universe so it wraps the space time so much that bunch of stars with their plants roam around it. one day or another there will be no galaxy’s remaining because of hawking radiation as black hole are losing energy because of the empty space, as in empty space virtual practicals came into existence and annihilate each other and become nothing. When this process happens at the edge of a black hole than practical which is inside of the black hole will get inside the black hole and the outside particle will be deflected to the outside, so the black hole is losing the energy but this process is very slow. So we can say that there will be no galaxy's remaining later after a long time when there will be no black hole.

Jupiter the most interesting planet in our solar system because of Jupiter we are alive. Now tell me truth who thinks Jupiter is ugly. I know you wouldn't say  but you feel that Jupiter is ugly but after reading this article this will change how you may wonder, let's find it out;

On 2016 Juno arrived at Jupiter and it has taken some amazing pictures of Jupiter, because of Juno now we know Jupiter is not ugly and the most beautiful planet in our solar system. Now you may wonder why didn't we get to know about this before? Some of you guys don't know a satellite was launched before also but it didn't do anything as the gravitational field of Jupiter sucked it in. So why Jupiter didn’t suck this satellite in? As Juno is not circling the planet normally. Because of Jupiter's gravitational field when Juno gets closer to Jupiter it is at very high speed so because of that speed Juno manages to get out of the gravitational field of Jupiter the closest point that Juno gets closer to Jupiter is about 4,200km and the farthest point is 8.1 million km and each orbit takes 53 days to complete.

What is there in light that it is so fast, let's find it out; Light travels 299792458 meters per sec we can't travel that fast. Why can't we go that fast? As we increase our speed we will need more and more energy because we got mass and light doesn't have any mass. So if we try to travel that fast we will need infinite numbers of energy but as light didn't got any mass so it can go that fast. That is what light is the fastest in our universe.

Why don't we have a ring like Saturn? why is it so, let's find it out; Our moon is big very big the diameter of our moon is 2159 miles which is very big. Our moon is too far from earth it is about 361747 km from earth because of our moon is big that is why we can see the moon clearly. As it is so far from earth that is why we have a solid one piece moon if our moon gets closer to earth the gravity of earth will rip the moon apart creating a ring like Saturn but if our moon gets closer to the earth which it is never going to happen.
