Why didn’t the world fall into space?

  1. The Earth revolves around the Sun in the great expanse of space. The orbit around the sun is around the sun’s equator. So, the question is whether or not it will go down if it goes around in this line.

This is a question that many people ask when they see the Sun from Earth and the planets orbiting it.

Before answering this question, the planets revolve around the sun in the plane above. The view that there is below must be cleared first. Anyone who draws a picture of the Earth moving around the Sun usually puts the north side of the world at the top. So, for everyone who sees this horizontal picture, the north side is the upper side. The view from the south side is seen below.

The consequence of this is that if people are standing, In this picture, we tend to see the upper and lower as if the lower has become So, seeing that the “bottom” of the world is empty, the question arises as to whether the world will fall to the bottom as seen in the picture.

Here, let’s take a look back at how the world turned upside down.

The world is big. We humans are stuck on the planet because of its gravity. So our lower side is the earth, and our upper side is outer space. For a person standing at the North Pole, the northern sky is above him, and for a person at the South Pole, the southern sky is above him.

So, for us in the world, It is obvious that it is due to the gravity of the world. So the world is in open space, and there is no up and down?

It is not. On top of the world There is one below. But not up and down like in the pictures.

The earth is drawn by the sun. The Earth revolves around the Sun because it cannot escape from the Sun’s immense gravitational pull. So, the sun is at the bottom of the world.

When people fall from the height of the sky, they fall to the world below, right? So why didn’t the earth fall into the sun?

The world is actually falling towards the sun. It has been falling nonstop for thousands of years. But at the same time as this is falling, the world is moving forward. So when the forward speed and the falling speed collide, it will fall, but it will never reach the sun again. Go ahead, fall down. It goes around the sun as it falls forward.

It is similar to the satellites orbiting the Earth. Satellites in Earth’s orbit are moving forward while circling the Earth and falling down at the same time. This forward movement and fall are timed so that they can orbit the earth without falling back to earth.

As the planets revolve around the Earth, they gradually slow down. If this slows down, you can speed up again. If you can’t put it this way, the downward velocity will not match the forward velocity, so it will fall to the earth.

This process is called “Free Fall” in physics terms.

The first person to think of this concept was Newton, who was able to develop the formula for gravity.

He gave the example of shooting a cannonball from a very high place in the world. If you shoot this cannonball, it will fall down due to the earth’s gravity as if it were going forward and fall to the ground. If the cannonball is fired at a higher velocity, it will travel farther forward before hitting the ground.

He continued to think that if the cannonball were fired at a much higher velocity than before, it would travel much further before hitting the ground. If you could fire a cannonball with enough velocity, the cannonball would fall downward, but its velocity would carry it, so it would fall and not hit the Earth. Because the world is curved, the cannonball falls under it, but it is no longer able to reach the curve of the world.

The result of this is that the cannonball falls all the way to the earth but never hits it, and life goes around the earth. (Atmospheric resistance is hidden here.)

If the Earth didn’t fall into the Sun because of the Sun’s gravity, it would continue to travel at its own speed and be blown away into space.

It’s not the only world that keeps falling towards the sun like this. All the planets in the solar system are constantly falling towards the sun while rotating.

So nothing falls into the sun. This is not the case. There are meteorites and asteroids that fall into the sun. But after falling, these objects completely disappear as they burn up and evaporate under the hot sun’s temperature.

They are not falling from planets to the sun. The moon orbiting the earth is falling on the earth all the time. Because of this fall, it is able to orbit the Earth without escaping from the Earth’s gravity.

Similarly, the moons of planets orbiting other planets in the solar system are constantly falling onto the planet they are orbiting.

Our sun. The sun is always falling into the center of the Milky Way galaxy. But since the sun is moving forward, it is in free fall just like the earth is orbiting the sun, and it is orbiting the center of the Milky Way Galaxy. Not only the sun, but all the other stars in the Milky Way orbit around the center of the galaxy. In other words, all the stars in Mickey’s Way are always falling into the center of the Milky Way Galaxy.
