Yesterday, I read several articles about a recently published research on gravitational waves. The research, conducted by NANOGrav, has been underway for the past 15 years. Interestingly, the publication coincided with similar publications from various other countries and institutions. These collective efforts confirmed the existence of low-frequency gravitational waves, which are responsible for altering the very fabric of the universe. What this also proves is that Einstein was correct in his hypothesis and what is more fascinating for is that we are making one more step to understand some aspects and the mechanics of our universe and how we came to existence.
Let's delve into what gravitational waves are.
Gravitational waves are gravitational intensity waves generated by the accelerated masses of an orbital binary system. They propagate outward from their source at the speed of light. The concept of gravitational waves was initially proposed by Oliver Heaviside in 1893 and later by Henri Poincaré in 1905 as waves analogous to electromagnetic waves but with a gravitational nature.

Now, let's learn more about NANOGrav.
NANOGrav, short for the North American Nanohertz Observatory for Gravitational Waves, is a consortium of astronomers who share a common goal of detecting gravitational waves. They achieve this by regularly observing an ensemble of millisecond pulsars using the Green Bank Telescope, Arecibo Observatory, and the Very Large Array. NANOGrav collaborates with international partners involved in the Parkes Pulsar Timing Array in Australia, the European Pulsar Timing Array, and the Indian Pulsar Timing Array, all of which are part of the International Pulsar Timing Array.
So Guys How close do you believe we are in unlocking the mystery of existence ?
