Nowadays almost everyone is familiar with the word "BIG BANG" reason being The Big Bang Theory series, but only few know what big bang actually means. The word Big Bang literally means very big/huge blast which many(including myself) believe to be the cause of the creation of this universe. Basically most of the people supporting the big bang theory believe this whole universe began from a single singularity and our universe came into existence as the singularity expanded. In simple terms, about 14 billion years ago Big Bang happens prior to this all the matters and spacial energy were the part of the singularity(whatever existed before the big bang) although everything we see in this cosmos wasn't in the singularity, big bang certainly became the foundation of the creations we see today. Edwin Hubble was the first to come up with the idea of Big Bang. He observed that the universe is constantly expanding and the velocity of a galaxy is proportional to its dist
Although we enjoy our life here on earth, there are pretty interesting and weird things that happens throughout the space. So, following are the list of some interesting things that takes place in the cosmos :- 1. Decrease in the force of attraction as the distance increase. It is a very basic phenomena which was discovered by Newton as his "Law of universal gravitation". As per Newton's law of gravitation, the force of attraction(gravity) decreases as the distance between two gravitational bodies increases. This is a universal phenomena which can be seen throughout the space. As per Newton, all the objects attract each other through a certain force called as gravitational force. "fg=gm1m2/r2" is the equation which was discovered by newton as the law of universal gravitation. 2. Mass of the object increases with the increase in speed. E = mc 2 is the most famous equation made by Albert Einstein, this equation is a part of the famous "T
