WHAT IS GRAVITY?

HOW DOES GRAVITY AFFECT TIME

Before we get started I want to tell you that this is the first article on gravity. We will be publishing the other article of this series very soon and just one more thing this is a small article. So, Let's get started.

Gravity, this is the force that governs our everyday lives. It pulls us down prevents our solar system from flying apart but the ultimate question is, what is gravity? To understand gravity we have to understand what our universe is made out of, So the two basic elements are space and time. Without these two important elements, the universe would not be possible, However too many physicists especially Isaac Newton believed space and time were two different entities that had absolutely nothing to do with each other. But Einstein saw things differently.

Albert Einstein saw things differently to him space and time were actually one and the same, he called this interwoven entity of space and time. Space-time, you can think of space-time as a continuum or fabric that permeates the entire universe. Everything in our universe all the stars, galaxies, and planets rest on this fabric of space-time. 

In the presence of matter and energy such as a planet, the fabric of space-time begins to wrap around the object and this warping of space-time in response to energy and physical entities are what we perceive as gravity and for those of you who are bored there's actually something interesting that comes from this you see gravity as mentioned earlier not only warps space but it also warps time which means the more gravity there is the more time is warped and gravity warps time by slowing it down so increased gravity means slower time and this is weird and wacky property of space-time which can be infinitely beneficial to us.

Black holes have a gravitational pull of about 1 million G's this is strong enough to trap light now. let's say that you got into a rocket ship and traveled very close to a black hole now the gravity near a black hole would be so strong that its effects on the warping of time would be magnified. So while time on earth might be going at the normal pace we're used to in our everyday lives, near a black hole time would be slowed down so much that if you stayed near a black hole for approximately two hours back on earth fifty years would have passed and if you stayed near a blackhole for approximately seven years back on earth five hundred years would have passed and that's just the beginning if you think that gravity is weird on a macroscopic scale to wait till we get to an atomic scale but I'm afraid that would take a whole another article to explain so this concludes part one of the gravity series. 

I hope you really enjoyed this article and be sure to leave a like, comment, and share this article with your friends and family.
