What is Gravity?

Image
  So what exactly is gravity? We define gravity in many ways, including stating that it's a "force" in the universe exhumed by massive objects but  Albert Einstein defined gravity as - it was a "consequence" of the bending of spacetime. I'm sure you have your own ways to describe what it is and what it isn't, but the technical definition is that it is: "a natural phenomenon by which all the matters with mass or energy including planets, stars, galaxies, and even light (it is a form of energy) are brought toward (or gravitate toward) one another." To put it in your perspective, every object, even you and I, have our own personal gravity field. The problem is that while we do exert our own gravity, it pales in comparison to what the Earth's is. Thus, when two people stand next to each other, the lighter person doesn't get pulled directly into the other person, because Earth's gravity overrides that. The Earth as a whole has such a str...

Are We Living In a Space Opera Universe?

Image
We humans are always excited to learn about planets, galaxies, stars, asteroids, and what’s there deep in space. This urge for exploration has led us to execute many successful space missions. These all have become possible due to technical advancements but the people had already imagined some stories and concepts set in space and those narratives are space operas. Let's look into our space opera universe which is made up of trillions of superclusters in which there is a tiny cluster called VIRGO supercluster, and a supercluster is made up of trillions of clusters among which there is a small cluster called  VIRGO cluster, a cluster is made up of several galaxies in which there is a galaxy called MILKY WAY, a galaxy is made up of several solar systems of which there is our solar system which has eight planets and a star called the sun, amongst these eight planets there our planet called EARTH where we are living. Millions of years ago, our universe took birth. From birth to now, it...

Graphene- The Wonder Material.

Image
Graphene was first demonstrated by Andre Geim and Konstantin Novoselov, two physicists from the University of Manchester, in 2004 for which they had won Noble Price in 2010. Scientists argued that strictly 2 dimensional crystalline materials were thermodynamically unstable and could not exist. Graphene is a single layer (monolayer) of carbon atoms, closely bound in a hexagonal honeycomb lattice. It is an allotrope of carbon in the form of a plane of sp2-bonded atoms (though carbon has a valency of four, due to similar reasons as that of graphite as it is derived from it) with a molecular bond length of 0.142 nanometres. Strength of Graphene Layers of graphene stacked on top of each other form graphite, with an interplanar spacing of 0.335 nanometres, these layers are held by Van der Waals force. The separate layers of graphene in graphite are held together by Van der Waals forces, which can be overcome during exfoliation of graphene from graphite. There are about 30,00,000 layers of g...
