How Earth is at the Center of the Universe
The question of what is at the centre of the universe has plagued scientists and non-scientists from centuries. In the past people believed our earth was at the centre of the universe and everything, including the sun, revolved around it. This concept was known as geocentrism and various dictionaries define it as "a belief or theory that the earth was at the centre of the universe".
But this geocentric concept was disproved when it was scientifically discovered that the earth and other planets revolve around the sun. And it was also proved that it is not possible for our earth to be at the centre of the universe, because it is just one tiny object located somewhere in the mighty milky way galaxy. Besides, the universe consists of millions of such mighty galaxies with each consisting of billions of planets and stars. For example, if you look at the picture of the milky way above you can clearly see that it is impossible to precisely locate where the earth is. Also anyone can immediately conclude that the earth cannot be at the centre of such a shapeless milky way either. So case closed.
Now this is where everyone who opposes geocentrism is wrong and I still say that the Earth is definitely at the centre of the universe.
To understand my unscientific statement look at the way I see the universe. For a brief moment forget about what is revolving around what. That is, don't bother if the earth and other planets are revolving around the sun, or if the sun is somehow revolving around something else, etc. Let anything revolve around anything. Now look at the picture below to understand the meaning of the word centre.
Geometrically, the black dot is said to be at the centre because the radius r is radiating equally on all sides around the dot. Now assume our earth is that black dot and forget about the existence of all the other planets, stars, suns, galaxies, etc., around it. Let them become invisible. That is, imagine that the earth is all alone in the universe for a moment. Now as we all know the universe has no end as it extends to infinity in all directions. And no scientist has yet proved that the universe has an end geometrically. So with this mathematical information on hand, let us come back to the circle and start extending its radius indefinitely into infinity. When the radius starts expanding does this not mean that the earth is standing at the centre of the universe when the space around it is radiating in all directions into infinity equally? So doesn't this prove that earth is really at the centre of the infinite universe?
Now let me tell you one more cosmic secret. It is not only the earth that is at the centre of the universe. Every cosmic object like the sun, planets, stars, moons, asteroids, etc., are also at at the centre of the universe because space radiates equally around those objects also into infinity. Just apply the same circle analogy to these objects also and the conclusion will be the same. Hence, all cosmic objects in the universe are always at the centre of an infinite universe. Isn't the universe amazing?
Happy to be disproved. Please send your views to email@example.com
Finally, we shall end this article with a quote by Blaise Pascal who said - Nature is an infinite sphere of which the centre is everywhere and the circumference nowhere.
