How can we describe the wonders of this world? The precision involved placing the different planets, stars, galaxies at a specific distance, their compositions, the movement patterns of those celestial bodies, and their speed of expansion, rotation, and revolutions!
We are living in a scientific era. The scientists could calculate the size, distance, speed, weight, the composition of many celestial bodies in the cosmos. We have many theories to understand various natural phenomena.
Let us take the example of earth, our home. What is the speed of its rotation on its axis? Almost 1000 miles per hour! Its revolution speed around the sun is 67,000 miles per hour! When our planet is moving at such a tremendous speed, we still stand straight, sit, sleep, relax as if it is stationary.
How can we stand so comfortably, despite its rotation and revolution with the cosmic speed? We all know about the gravitation theory and the force that make us stay on the earth. But who has decided the exact amount of the gravitational force needed so that we could evolve as human beings and live on the earth? If the earth had higher gravity or lower gravity than the present value, whether we would have evolved differently? We have enough technology to calculate the speed and duration of the earth’s rotation and revolution. But, how did the earth decided on those values and maintaining the same for billions of years? How did the sun get the exact quantity of nebulous material to evolve the solar system? It is amazing to read about the formation of the sun and the solar system.
Let us explore the genesis of the earth as per the theory:
About 4.6 billion years ago, our solar system was a loose collection of gas and dust (Nebula). There was some trigger, that caused a pressure change in the center of the cloud. The origin of the trigger would have been a supernova exploding nearby, or a passing star changing the gravity. Whatever the reason, the cloud collapsed and created a disc of material.
The center of this disc saw a very high increase in pressure that eventually was so powerful that hydrogen atoms loosely floating in the cloud began to come into contact. In due course of time, they fused and produced helium and initiated the formation of the Sun. The sun was a hungry youngster that ate up 99% of what was swirling around. It still left 1% of the disc available for other things. Small bits of dust and gas began to clump together. And this is where planet formation began.
A Sun-like star usually takes approximately 1 million years to form, with the protoplanetary disc evolving into a planetary system over the next 10–100 million years.
In that complex process, I have no words to express the wonder of the formation of the Sun. What can we say about the subsequent formation of planets, satellites, comets, and other cosmic objects and the precision involved in it? What about the splendor of the genesis of Earth and its evolution as the only planet to host living beings in the entire solar system? Isn’t it a wonder that Earth has got the exact composition of terrestrial, gaseous, and liquid substances that could host living beings in it?
Is it a sheer chance that the earth has evolved in this manner to give birth to the innumerable species on it? Which calculation has worked on the splendid composition of the earth, its speed of rotation and revolution? How was it done? If all of these are natural phenomena, then even the evolution of species on earth and eventual entry of human beings on it!
In this big world, Earth itself is a speck of cosmos, and we are born as human beings, after this complicated process of evolution of life on earth. Isn’t it fortunate to be born as humans in this era?
As we learn more, we have more things to learn about the world. There is no limit to the wonders of this world that could keep us guessing and working to understand them all.
Whether Earth would have been a better place without having humans on it? Maybe, all other species of living beings would have had a better life without human interference in their life. But you never know, some other species would have become powerful and started harming the earth in different ways…
Earth day was here on 22nd April with this year’s theme; Protect our Species to save most threatened and endangered species on the earth.
However, knowing that we have the highest privilege to live on Earth as a most evolved species, shall we show a bit of gratitude and respect to our planet? Could we work towards conserving our environment? We are too small in this big universe. Still, let us do our bit to protect our environment, natural resources, and endangered species on Earth.
Think, how can you contribute to reducing pollution and conserve the environment on Earth. Here is a list from which you could take up an action or make your pledge to conserve the Earth.
- Save water
- Eat less meat
- Quit plastic bags
- Buy local produce
- Reduce your food waste
- Plant a garden/Plant a tree
- Donate unused clothes and household items
- Switch to natural cleaning supplies to clean your home
- Open the window and reduce the use of air conditioners
- Walk, use bicycles and public transport as much as possible
- Reduce, Reuse, Recycle — Three great ways to eliminate waste and protect our environment.
