Have you ever wondered you are going to travel to Mars? As a common man, it is near too impossible for thinking about the situation but NASA had started a new program called Send Your Name To Mars. Under this program, NASA has started an online form filling. Link to this program will be given. To send your name to mars you have to just go through the link which I will provide you. If you do not know how to fill the form, fill your form with the science behind science- Here is the link "Send Your Name to Mars: Future Mission" Fill the form fast and make your friends jealous of the boarding pass. But don't make them that jealous share th e link to your friends and family as fast as possible. The link is given here for how to fill form and link for the form:- Share the link fast because forms are filling fast:- https://truesciencebehindscience.blogspot.com/2021/02/send-your-name-to-mars-mars-2020.html First, you have to go through the link given below: The link will direct...
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 -

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 carbonate and the level of these poisonous gases decreased very highly.
The decreased level of carbon dioxide resulted that now the earth's atmosphere was not able to hold the heat of the sun so, the temperature also get decreased. This was the time for an ice age. But the ice age also did not last long, the volcanoes blew up once more. The earth's atmosphere got enough carbon dioxide to trap sunlight. The ice started melting on earth.
About 540 million years ago, all the ice had been melted. Now if we go inside the oceans, we could see different types of multicellular organisms such as Anomalocaris, pikaia (they contained backbone in them), opabinia, etc. The single-celled organism had evolved into multicellular organisms.
About 500 million years ago, the earth's atmosphere had enough oxygen, and earth had enough water also but one problem was not allowing organisms to come out of the oceans. The UV rays weren't allowing the marine animals to come out. But this problem also not lasted long. The new layer for our protection was completely built, today that layer is called the Ozone layer.
About 460 million years ago, after the formation of the ozone layer first plant came on land called mosses and liverwort. After them, some multicellular plant's also evolved on earth. Then came the first marine organism that came out of water namely Tiktaalik. This fish moved on land with the help of its fins. Later, these fish were able to live for more time on land this process evolved its organ. After the evolution of 15 million years, this organism changed to a new organism called tetrapods. The organs of this organism were highly modified and this organism needs not to go inside the water. From this organism, only all other organisms evolved.
Later, once more volcanoes got active and this led to a great famine which led to the end of 95% of organisms on earth. Due to this famine, only those organisms lived who adapted themselves to the condition. The organisms which were left started eating everything they could and started living underground.
About 200 million years ago, the matter from volcanoes made some new parts of the land, and the tectonic plates once more combined and led to the formation of Pangea. The conditions on earth were reviving the population of the earth was once more became enough. In this enough population, some new organisms also came into existence commonly known dinosaurs who were going to rule the earth for 165 million years.
The dinosaurs were also categorized in many ways such as some were carnivores other were herbivore, some were peaceful but some of them were angry ones, some lived on some lived in water and some of them flew. Many dinosaurs were 10 times as big as today's bus or elephant. The birds have evolved from the flying dinosaurs only. At the times of dinosaurs, there was a small mammal that looked like a rat and lived under the ground because of the fear of dinosaurs but this character was going to be a boon for them.
These big lizards ruled on our earth for more than 165 million years. But, what happened to them which led to the end of their existence What was the cause for the extinction of dinosaur? We will know about it later.
