A force called gravity

Many of us must have heard about the word gravity and also gravitational force. But we may not be that familiar with what lies behind the legend called gravity. For centuries Many people before Kepler has always believed that the universe was held in place by divine intervention, anybody who has contradicted Opinion to that was either killed or label a mad man. From earth quakes to tornado to the rise and fall of the oceans tides to the motion of planet around the sun. Many used to believe it work because it was divine intervention.

But there are people who where ready to ask questions and feed thier curious mind about why does thing walk, it took great minds like Isaac newton, Kepler, Albert Einstein to unlock the secret of the universe and the secret behind every motion of planetery bodies and also tides.

What is gravity?

Well gravity is a natural phenomenal by which all body with mass are attracted toward each other.

It took aN apple falling down from a tree and the mind of Isaac newton to laid down the early foundations of gravity, and these simple foundation has helped us to understand our world more, why planets orbit thier stars instead of moving in a straight line. The secret behind how stars shine, and also the rise and fall in tides of oceans due to the gravitational pull from the moon.

Despite how successful Issac newton laws of gravity was, it still had some short comings it could not explain some thing that occur in nature, such as the anomalous motion of the planet mercury and also some other details.

The modern laws that govern gravity are called the General theory of relativity which was discovered by Albert Einstein and these law combined with the Einstein field force equation is the Mathematical frame work behind modern gravity. Well these general relativity has helped alot in human exploration of space and also help to answer questions about the origin of our universe and also the possible end of our universe.

It also helped to answer questions about the anomalous motion of the planet called mercury.

And some solution to the general relativity equation predicted some phenomenal which has been detected natural, such as the existence of blackholes, gravitational waves and many other things.

DO YOU KNOW!!

1.Compare to other forces of nature, the gravitational force is the weakest of all forces, that is other forces of nature such as Electromagnetic force, Nuclear force, are dominant.

2.according to Albert Einstein, gravity is not really a force but a warp in space-time continum. There is quote that says space tells matter how to move and matter tell spaces how to bend.

3.without gravitational force as a dominant force in the early universe, the universe won't have existed today, because Scientist Believe that the force of gravity is what shaped our universe to how we see it.

4.gravitational force also have the ability to slow the motion of time, these is one of the secret behind using a blackhole as time machine in later future.

5.there is a region in our universe where the force of gravity is so strong that even light can't escape it and every laws of physics that you know breaks down, they become ineffective.

6.Scientist don't know how the force of gravity became a weak force despite being one of the dominant force in the early universe. And the force of gravity is infinite, that is no matter where the body might be the force of gravity can still act on it.

Science is everything!!!

Be curious about everything you see, who knows where the next great discovery is coming from.
