Consequences of gravitational force, and the influence of the moon on the earth
The gravity, based on popular knowledge, was discovered in 1666 by the physicist and mathematician of English nationality Isaac Newton after, one day like any other, when he was sitting under a tree from which an apple would fall to the ground. From there arose his inspiration to develop his future research in which he would conclude with the discovery of what we know today is gravity, of course, in a more primitive way. He already had certain previous knowledge, but his work would end up being called Philosophiae Natural Principia Mathematics, where he establishes his universal law of gravity.
Starting with the effects of gravity in our lives, its influence on our body and earth, we can mention how we adapt to it, because it can be concluded that this is necessary. Our weight, as such, is a result of our mass multiplied by the magnitude of the gravity exerted on planet Earth that would be 9.8 m/s, and as such, more or less strength will be required to be able to move with some ease. This assuming that we do not practice any very demanding physical activity, because if that were the case, even more strength is needed by our muscles to counteract the attraction to the soil that seriously exerts.
Scott Kelly is an ex-overtonaut who was located almost a year (340 days) in the E.AND.Yo. or the International Space Station. This astronaut states that spending a lot of time outside the earth can lead to "devastating effects" both physically and mentally, given that "the total and absolute isolation of all terrestrial comforts consumes one" or that mentions the astronaut. In total this man has spent approximately 520 days in space;The 340 days in a row that he spent outside the planet Earth was part of an experiment that was carried out to investigate the numerous consequences that spend a lot of time outside the earth, live without gravity, and with high radiation can have in the human body. The astronaut had a twin brother who was "monitored" directly from Earth to compare differences. Scott Kelly mentions that when he returned to Earth he felt dizziness since his body had to get used to gravity, he also mentions that approximately 7% of his DNA behaved differently, but this is not something that can be seen or feelingFinally, what was most noticed was the stature difference of 5 cm due to the lack of gravity, this is even more amazing or peculiar when it shows that this astronaut was approximately 51 years old when he left on his trip and at this age thepeople do not grow entirely on earth. This experiment in general gives us a more "widespread" idea of what is affected by gravity not only in our daily life but in the long term also.
Apart, it is essential for the purposes of this essay to mention the influence of the gravity exerted by the moon in our lives. Throughout history, many religious, artistic and cultural symbolisms have been attributed to the moon. It is iconic in many ways, however, it is of importance that transcends the interpretation of the human being, has a very important physical effect in our lives and for the earth. This also has its strength of gravitational attraction, because every massive object has its own gravitational field that depends on the mass of the object in question. Although the moon is a satellite, obviously smaller than our planet, it remains an object of great mass that exerts remarkable strength on Earth.
One of the clearest examples of this is found in the tides, the frequency and size of the tides are affected by this previously mentioned influence;It is known that the closer an object of the other is, the force of attraction between them will progressively increase. Following this rule, in a hypothetical case in which the moon was much closer to the earth, the water level in the seas increases extremely, the tides would be able to completely submerge, and make it disappear, to whole cities likeLondon or New York, according to an expert in a BBC documentary. Continuing with this, the tides create a friction in the rotation of the Earth that, by itself it is minimal, but over thousands of years it accumulates to generate a significant difference. Without the moon the days would be shorter and the nights, apart, much darker because the brightness of the moon, although it is a reflection of the light of the distant sun, is enough to give visibility at night. Finally, something very important is that this moon attraction also maintains the angle in which the earth revolves on its own axis, which prevents it from changing and there are no events, however dramatic it seems like, catastrophic.
In conclusion, it can be denot. As this has been from the beginning, it is easy to assume that it will be until the end of the world as we know it. It is expected that properties of gravity are still discovered that allow us to know more about the universe that surrounds us, and how it can help us in our constant scientific development.
