Interesting things that takes place in the Cosmos.

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.


Law of gravitation

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.


Theory of relativity

E = mc2 is the most famous equation made by Albert Einstein, this equation is a part of the famous "Theory of special Relativity". Basically it means the faster you go the more your mass increases. As per this equation it'll be impossible for any object( which have a mass) to move with the speed of light. Since any object's mass will increase as the speed of that object increases, thus it is impossible to move by the speed of light as we haven't found any object which have zero mass. This is also a universal phenomena which happens all across the cosmos. This phenomenon can be understood by taking a bullet as an example, as a bullet without speed is harmless to us, when it's speed increases resulting in the increase in its mass, it becomes deadly.

3. The distance decrease as the speed increases.

It is a phenomena which was discovered by Hendrick Lorentz and further corrected by George Francis FitzGerald. Although this phenomena seems very basic and simple, it isn't. This phenomena can also be named as space/length contraction. This phenomena does takes place in slower objects but its effects on an object moving with normal speed is so negligible that it gets ignored or unnoticed. As for an object which is moving with a higher speed(electron motion), the effects becomes significant. This phenomena basically suggests that any object which was measured "x" when it was idle, will be measured shorter than its original length when it is moving close to the speed of light.

4. Time passes differently in different areas of the cosmos.


Time dialation

In simple terms, time is relative. Earlier it was believed that time passes equally no matter where you go but this theory was debunked by the "Theory of Relativity" discovered by Albert Einstein. According to the theory of relativity, time gets bent due to gravity. It means, time moves faster where there is less gravity and slower where there is high gravity. This Theory of Relativity also provides a possible way/idea for time travel. Although going to the future is not possible yet, there is possibility for us to travel to the future. All we have to do to travel to the future is to move to a place where there is a higher gravity than earth and then return after certain time. As we do that, we will see more time have passed on earth than that of the place where the gravity was greater, thus it will be a possible time travel to the future.

Life of a star

Sun, a star which is the source of all the life forms on earth is a star, a star which have only half of its life left. So you might be wondering what happens when a star dies, thus following are the whole life cycle of a star :- 1. Nebula. Nebula is basically a lump of dust which consisting hydrogen, helium and many other gases. It is a the first phase of a star or could be said as it's birth place as well. When a nebula collapses, all its gases and dusts combines to form another celestial body called as "Star". 2. Star. This is the infancy period of a star. Star is sphere of plasma born from nebulae which contains gases like hydrogen and lithium. The temperature of a star varies from 2,000° C to  30,000° C. A star produces its own heat and light due to the continuous nuclear fusion.  3. Red Giant. As the time passes, the surface of a star becomes colder while it's size increases. Despite of having a cold surface, it shine many times brighter than its previous...

Mysteries of the Cosmos

1. Formation of galaxies. The biggest mystery of this universe is its own formation. In other words, how the galaxies/universe or any of this is formed. Most of the scientists are sure that this whole universe came to the existence due to a big bang but still there are some other facts to deny this theory. So nobody is totally sure about how this universe came to be. Since the mystery about the existence of stars and planets was solved not too long ago, scientists are now looking at a bigger picture i.e, the mystery of the existence of galaxy. 2. White Holes. Since the theory about the existence of black hole became right, scientists are now looking for the existence of white hole which was also proved by a theory alongside the black hole Theory. Totally opposite to black holes, white hole spits matter and energy instead of sucking it. As no one was able to find a white hole till this day, the existence of white holes is still a mystery. 3. UFOs. UFO or Unidentified Flyi...
