We all have heard about Einstein's gravitational waves. But what are these exactly? Let's see...
Gravity is the attractive force with which two objects pull each other.
However, Albert Einstein imagined gravity as well as space and time a little differently. His theory of general relativity unified two separate entities space and time into a single entity called spacetime. Spacetime can be considered as the fabric of universe.
Now, just like a heavy ball creates a curve or distorts the trampoline, mass of an object creates a curve in spacetime. According to Einstein, this curve is gravity.
Now, just like our hands create ripples in water, moving objects create ripples in spacetime. These ripples are termed as gravitational waves. Gravitational waves were directly observed for the first time on September 14, 2015 by Laser Interferometer Gravitational Observatory (LIGO) in the US.

I thought it would be better not to delete or revamp these posts, even if they suck. The bitter truth is that old works always suck, but I take that as a positive tool to convey that I am growing. Besides there's no better way to showcase my journey without these old, messy, poorly written posts!
