Hey, this is Science Feed, and this post is about Falcon 9, one of the most advanced rockets in the world.

SpaceX has designed and developed it for payload transfer to Earth orbit and space. Over the time period of 10 years, Falcon 9 has been launched 85 times, in which 46 launches were able to land. Due to its capability of landing, SpaceX has saved costly parts of the rocket. This rocket uses rocket grade kerosene (RP-1, it is cheaper but less explosion hazardous fuel, which is a highly pure form of kerosene) as its fuel and liquid oxygen as an oxidizer.  In 2007, SpaceX started the development of Falcon 9 which was boosted by the funds provided by NASA.

Have you ever thought why we have not found any advanced intelligent organism yet? Or is there any other type of life form outside our planet Earth? These are the basic questions that come into mind when we talk about Fermi Paradox. Fermi Paradox Fermi paradox is the lack of compatibility or contradiction between the high chances of existence of extraterrestrial civilization in the universe and lack of evidence to find them or communicate with them. This was termed after the name of physicist Enrico Fermi. It casually came in head of Fermi during talk with his colleagues and he asked, "Where is everybody?". Early and Related Theories Before Fermi Enrico, the founding father of modern rocket science  Konstantin Eduardovich Tsiolkovsky, a  Russian scientist, proposed Zoo hypothesis. In Zoo hypothesis, it is speculated that the extraterrestrial civilization knows about our existence but instead of contacting us, they opt to do observation on us similar to animals in zoo.  The ot

By the basic definition evolution is "the process by which new species or populations of living things develop from preexisting forms through successive generations."  And by scientific terms it goes, "species can change over time, that new species come from pre-existing species, and that all species share a common ancestor." Now we read above lines again and find that both of them are basically the same thing while proving to be wrong at the same time. While many naturalists / geologists proposed their theory on the evolution of life only two of them gained massive attention, that is one being Jean Baptiste Lamarck, one of the best-known early evolutionists, and the other being infamous English naturalist that the world known as ‘Darwin”. Lamark first ever published his views in the year1801, later in “Philosophic Zoologique" in the year 1805 and subsequently in year 1809 in his book 'Histoire Naturelle Des Animaux Sans Vertèbres’. His works entails th
