End of the world THEORY

how interesting is science. But for now idk if this theory is right or wrong but that's why it's called "theory" who knows.

How does Earth keep its orbit around the Sun and not come closer to the Sun.

Answer 1:
The Earth is always being pulled towards the Sun by gravity. If the Earth were stationary compared to the Sun, it would fall into the sun under the force of gravity. However the Earth is actually moving sideways compared to the center of the Sun at 3 km/second (~2 miles/second). The Earth is not moving fast enough to "escape" the Sun's gravity and leave the solar system, but it is going too fast to be pulled into the Sun. Therefore, it keeps going around and around - orbiting the Sun. It is rather like a tether ball. Think of the top of the post as the Sun and the ball as the Earth. The string between them is like the force of gravity keeping them the same distance apart. When you hit the tether ball it spins around the post. If there were no air or rope friction, the ball would spin forever without getting any closer to the post. That is essentially what the Earth is doing when it orbits the Sun - it the vacuum of outer space, it does not loose speed to air friction, so it just keeps going around the Sun.

Answer 2:
Well, that's a good question, and Newton worried about the same thing! Actually, due to conservation of angular momentum, all the planets are in fairly stable orbits, with minor changes over millions of years, but no chance that they will fly off or anything! The earth's orbit is in the shape of an ellipse, which means that we get a little bit closer and farther from the sun over the course of a year. We also wobble in the tilt of our axis, so that the North Pole does not always point to the star Polaris, which is currently our north star. But, the orbits are pretty stable, because there is a fairly constant gravitational force between the sun and the earth keeping the earth in its orbit. The strength of this force changes slightly over the course of an orbit,being a bit stronger when the earth is a bit closer - at those times(currently, when the northern hemisphere is having winter) the earth actually orbits a bit faster. (Not to be confused with spin!)

Answer 3:
The Earth is "falling" around the Sun. The Earth has some initial momentum - it is moving in a direction,which is perpendicular to the direction of the Sun from the Earth. The Sun's gravity is enough to keep the Earth from flying off in a straight line, away from the Sun, but not enough to bring the Earth closer in - the Earth is continually changing its direction of movement, but in such a way that it follows a nearly circular path around the Sun.
If the Sun's gravity were stronger, it would pull the Earth in closer, but then the angle between the Earth's motion would also be changing more rapidly, so it would continue revolving around the Sun.
This concept is called the conservation of angular momentum, which is one of the basic principles of physics

Answer 4:
Kepler's law and Newtons laws explains this very well. If we could just STOP the Earth for a moment relative to the sun and then allow it to freely move it WOULD fall into the sun. But the earth was born from a ring of material that was MOVING around the sun on a stable orbit. So after the debris coagulated to form the earth, this initial orbital energy was retained. Hence the earth is moving on a stable orbit of fixed radius. Look up Keplers laws the period of revolution of a body squared is proportional to the distance between the sun and the body cubed.

Some of your theory TS I highly doubt it, though I am not a theoretical physicist.

Sakto sila sa babaw, magkaduol ta sa adlaw magka kusog atong velocity.. Another thing ang sun dili mo boto kya bloated sa planet, planets will disintegrate (most likely). Muboto ang sun if mahutdan na siya ug fuel and start creating Iron and process of extinction will follow next

Nice explanation kudos. Most astrophysicist called the swing as Galactic dance to make it fancy hehe

[Nefarian]

When I wrote this theory I never really think about Physics hehe. Just my observation of things.

There are things that physics can't explain. We don't even know 90% what's under our oceans kana na nuon sa outer space hehe.

ge lang nindot unta tog sa akoang lifetime i can see it with my own eyes hahahaha pero ma wa sad ang life sa earth maikog tas uban

if we do not ground our conjectures on observable physical laws, our theories reflect something else that will not resemble what is actually happening, rendering our final conclusions invalid.

there are things that physics (and science) cannot readily explain (at the moment). however it does not necessarily mean that it never will as the boundaries of known science expand every minute with each accumulated observed knowledge.

our reservations, however, should not be placed against science and its explanations, but against those alternative explanations when science cannot readily provide an answer. time and time again, these alternative explanations have proven to be weak than the science that it dares to replace.

OT: a written statement of tesla mounting an attack on einstien's theory of relativity...
"I have worked out a dynamic theory of gravity in all details and hope to give this to the world very soon. It explains the causes of this force and the motions of heavenly bodies under its influence so satisfactorily that it will put an end to idle speculations and false conceptions, as that of curved space. According to the relativists, space has a tendency to curvature owing to an inherent property or presence of celestial bodies.

"Granting a semblance of reality to this fantastic idea, it is still very self-contradictory. Every action is accompanied by an equivalent reaction and the effects of the latter are directly opposite to those of the former. Supposing that the bodies act upon the surrounding space causing curvature of the same, it appears to my simple mind that the curved spaces must react on the bodies and, producing the opposite effects, straighten out the curves.

"Since action and reaction are coexistent, it follows that the supposed curvature of space is entirely impossible -However, even if it existed it would not explain the motions of the bodies as observed. Only the existence of a field of force can account for them and its assumption dispenses with space curvature. All literature on this subject is futile and destined to oblivion."

lingaw kos inyo mga theory dah...hahaha

[janrey1986]

nice theory..this gave me some thoughts to ponder today..
