Do you believe satellite is a conspiracy? Why?

Greetings, how are you steemit friends? Glad to see you again and hopefully healthy always, today I want to discuss something that we often experience, in fact, there are some friends who contact me asking "when will I continue the calculation of labor and material needs needed on construction work?", in fact. The discussion that the labor and material computations I have written in previous posts is sufficient for a friend who wants to build a simple house, and maybe I will continue the post next time. Today I will try to discuss what we often see, but is it true that everything we know is true? Hopefully useful.

At night, we often see so many stars in the sky. Without us knowing among the many stars there are also satellites, such as natural satellites (moon and so on) but there are also artificial satellites, really?

ARTIFICIAL SATELLITE

---

Russia first created an artificial satellite Sputnik I in 1957 that serves to identify the atmospheric density, after success with the launch of the satellite space program in several countries continues to be spurred, such as the participation of the United States and several other countries in the following year.

Keep in mind, the satellite is a celestial body that circles the earth at a certain distance, the artificial satellite is divided into 3 types ^wikipedia.

1. Low Earth Orbit (500 - 2,000 Km from the earth's surface)
2. Medium Earth Orbit (8,000 - 20,000 km from the earth's surface)
3. Geosynchronous Orbit (35.786 Km from the earth's surface)

Each artificial satellite is used for various purposes, such as for space research, communication, navigation, observing the earth, for military purposes, and so on.
It is estimated there are about 13,000 artificial satellites circling the earth, and several thousand of them are no longer activated. Wow?
Have you ever imagined there are about 13,000 objects above your head every day?

What if we have a little opinion?
If true there are about 13,000 satellites in space, then can you find it with a telescope?
We often see astronauts floating in the sky, Why? Maybe you will answer "because there is no gravity" but is there really no gravity out of space?

It has become common knowledge, that the moon circles/orbits the earth because the moon is affected by Earth's gravity, is it true? maybe you will answer "the distance of the earth with the moon farther than the distance of the earth with artificial satellites". According to the Wikipedia source the average distance of the earth with the moon is about 384,400 km, while the distance of the space station with the earth is 360 km, the question is, if the moon that has a longer distance from space station only has gravity, why the astronauts precisely closer to the earth just floating (no gravity)?

You may find an answer from a Ph.D. from the University of Sidney who says that actually, astronauts and space stations are actually falling, not floating, because the speed of the space station around the earth is very fast which causes the space station does not fall hit the earth's surface (speed of space station about 28.000 km/h), instead of falling to hit the earth, space station would eventually orbit the earth.

The constant acceleration caused by the space station due to the falling force actually causes the astronauts to feel not experiencing gravity (float). In accordance with Derek Muller's explanation, the astronauts in space station actually fall instead of floating in the absence of a gravitational force.

As we know, that the speed of sound is 1,235 Km/h while the speed of the satellite is 28,000 km/h or 28,440km/h or about 22.6 times the speed of sound, the question is, how great is the man creating a technology up to 22.6 times the speed of sound? As we know today one of the fastest combat aircraft ever created by humans is SR-71 Blackbird which is about 3.529 km/h or about 2.8 speed of sound.

FACT

The average speed of the satellite around the earth is 28,440 km, with this speed, the satellite is very difficult to find by space photo hunters. As we know space is a vacuum, the aerodynamics form is not taken into consideration by satellites, it is different from rockets launchers carrying satellites that should be designed aerodynamics because a rocket body will rub against an air so that the higher the rocket's speed a shape is designed to be more aerodynamic so that its speed is not hampered when the rocket body rubs against the air.

It should also be remembered that artificial satellites also have different speeds between one satellite with another, it happens because the farther the satellite from the center of gravity then the speed of the satellite around the earth is getting slower.

Did you know that a satellite does not require fuel to orbit the earth, solar panels are only enabled to generate electricity to be on a smaller scale to operate satellites (sending data, maneuvering avoiding space junk, etc.). This is in accordance with first Newton law ^wikipedia.

	First Newton Law "In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force". (∑F=0).[wikipedia]

You only need the initial velocity obtained when the satellite is released by the launch rocket.

The most terrible thing is when satellites collide with each other, according to the record that there has been a satellite collision in 2009 at an altitude of 789 km from the surface of the earth. although all satellites have been programmed to avoid accidents they may be different during the field exercise so that collisions cannot be avoided.

The rest of the satellite collisions are scattered in space with varying sizes, the rest of the satellite collisions then into space trash and join the orbiting center of gravity with an average speed of 28,440 km/h.
A regular gun bullet has an average speed of 300m/s, whereas a satellite waste has a speed of about 28,440 km/h or about 7,900 m/s. It sounds like deadly junk :D

CONCLUSION

---

In accordance with current technological advances, artificial satellites are one of the human needs, apart from being a means of communication and satellite research is also required by the military to spy on.

Currently, there are still some organizations that deny that satellite actually exists, one of them is Flat Earth Community, they assume satellite is a means of a conspiracy of elite countries. (I have no idea :P)

Whether satellite is true or not, we now recognize that we have tried to solve many of the mysteries of the universe through science, and some countries have special budgets for space programs, especially the launch of satellites.

If the satellite is the result of a conspiracy, then the question is, why? and who benefits from the conspiracy?

This is the only thing I can write on this occasion, over all the mistakes and lack of unintentional writing as a servant of God, I apologize.

Thanks to friends who have visited this blog and provided constructive comments, as well as scientists who are willing to sacrifice their time for a better civilization.
