Science behind Science -Know some more

Dinosaurs ruled on earth for about 165 million years. But how did dinosaurs become extinct? What was the cause of their extinction? The most important question how humans came on earth? All these questions will be answered today. So, let us wear our time travel suit and travel to the past with science behind science- About 65 million years ago, an asteroid was approaching the earth as it came under the gravity of earth its speed increased tremendously to 70,000 km/hr.  This asteroid was not a normal one it had a diameter of 10km. As it enters the earth's atmosphere due to friction it turns to a fireball. Its luminosity was at that peak that a big flash-bang was thrown on the earth. It almost blinded all the organisms who were in a radius of 1000 km from the spot. Dinosaurs couldn't see that incident but they could feel the heat. The great destruction had begun. The asteroid hit the surface of the earth. Now, this spot is called the Chicxulub crater today in Mexico's Yucatan...

In our journey to the past, we had seen the first bacteria, the chemo-synthetic bacteria, and the photo-synthetic bacteria then the supermassive continent called RODINIA. But wait, our journey was paused here only, so get your time travel suit and ready to be fired to 1.5 billion years ago with science behind science -  If you hadn't read the previous part of this then click the link given below - ALSO READ THIS:-   How our earth came up as a living planet? - First organism born - truesciencebehindscience . About 750 million years ago, The continent Rodinia has broken apart and the lava flushed out through the earth's crust. Once more the concentration of Carbon dioxide and sulfur dioxide increased in the earth's atmosphere but this time carbon dioxide reacted with water vapor to form Carbonic acid and sulfuric acid and hit the earth's surface forming solid carbonate and sulfate layer. So, most of the atmosphere's CO₂ and SO₂ of atmosphere settled on earth as solid...

Today we live on this planet , occupying all its resources . But you ever imagined how earth became a living planet. Many scientists and astrologists gave theories about how it became a living planet . Today we will know one of the most suitable theories on this topic. So, let's go 4.5 billion years back with science behind science -   According to some theories , our sun 's nebula was called Solar nebula . A small disturbance in the solar nebula started forming our sun. When our sun was being ready to burn till 9 billion years . Some rocky particles and dust started forming a planet , which is today called mother earth . When our earth was ready to be a planet , a big rocky substance came up in the gravitation of earth and revolved around it till now , today it is called moon by us.  Our earth was continuously bombarded every day with several meteorites. Till now, many meteorites had hit earth containing a high volume of ice crystals, nitrogen...

Have you ever felt that the earth is rotating, it is moving around the sun? our sun is not still its also moving with the sun earth is also moving. Moreover, our complete galaxy is in motion. We don't even notice that the earth is spinning at 1656 km/hr and our earth is revolving our sun with almost a speed of 108000 km/hr. It is very interesting to answer these questions because one can be answered by just relating it to our daily life and one is completely related to physics. So, let us find the science behind science- The Reason for Why we can't Feel the Revolution of Earth As I had mentioned above that our earth is revolving around the sun with a  uniform  speed of almost 108000 km/hr but we didn't felt it any time. While we move around with a vehicle that is almost 40-60 km/hr gives us the feel of the movement. How is it so? Is it just an illusion of physics? Let us consider an example, Assume that you are moving in a car on a straight road with no bumps and taking win...
