Ok i know we all know about gravity. But we still don't know what is that thing inside earth that pulls us all like a magnet! Isn't that a sad fact that we are still quite oblivious to this fact. Knowing gravity's equation is not enough!

Raj: I don't see how that link you gave or your explanation answers my question! Do you have proof of your magnet theory? Although it sounds good, i give u that!

it is an extremely good question. The apple additionally exerts a tension on earth. however the strain the apple exerts is extremely very small whilst in comparison with how lots the earth exerts. So the apple falls on earth. you additionally can prefer to comprehend that Newton's rules are in basic terms one explanation Gravity. Einstein has extra at the instant defined Gravity returned with known Relativity. Einstein defines Gravity as a bending of area-time by skill of remember. So the apple isn't in all probability pulled in the direction of the Earth. It follows the curvature of area-time around the Earth. Whoa! superb ?

Some answers seem to indicate that gravity has something to do with magnetic forces. It so does NOT !
magnetism and gravitation are completely different forces. there are 4 fundamental forces in nature. electromagnetic force is not the cause for gravity.
gravitational attraction is due to mass alone. anything which has mass will attract anything else which has mass. the newtonian theory tells us what will be the force of attraction, although it doesn't tell us why does masses attract each other.
einstein's theory gives another viewpoint. it says gravity force is just the manifestation of objects moving along geodesics in a curved space-time.

There is no "thing inside the earth". It is the earth. Everything that has mass attracts everything else that has mass. The earth attracts you, you attract the earth. Your girlfriend attracts you, though the gravitational attraction is probably a lot less than the hormonal.
Science consists of theory, experimentation, revised theory, revised experimentation. If not knowing the cause of gravity surprises and saddens you, it is because you do not understand science. There is still much in our universe to be discovered and understood. Learn more about gravity, and maybe you will be the one to figure it out!

The apple fell because plant hormones triggered at the onset of seasonal sun differences caused tree sap to stop filling the vesicles leading to the fruit body and daughter seeds contained within. The ensuing drying action of evaporation led to the eventual failure of the stem holding the apple to the tree at the natural cleft between the fruit body and the parent plant.
Gravity did what it does. Gravity is caused when the normally flat featureless expanse of spacetime is made to divot from an accumulation of matter. The fabric of space-time continually tries to return to its natural resting state. It struggles with the grains of matter caught in its folds. Eventually, a pearl forms from the pressure. Intangible layers of retracting spacetime intersperse the object and force everything closer to the center of the object (I always picture a giant hand smashing down the top of a hamburger bun).
The physical experience of gravity is spacetime attempting to return to its normal resting state.
Now that is always followed by the question "What is spacetime?"
Spacetime is usually interpreted as a four-dimensional object with space being three-dimensional (infinite in those three measures though) with time playing the role of the fourth dimension.
Time is the relative rate of change between electron particles and magnetic waves. Electron particles give rise to magnetic waves and magnetic waves generate electron particles. The two pulse and create each other. One flows into the other leading to more of the first.
The physical experience of this occurring is the passing of time. It is relative, in that it progresses at different rates depending on the speed you are traveling, your mass, distance from gravitational fields, and proximity to objects of greater mass (as well as other variables that are too esoteric to bring up here).
Space is the expansive plane that is both expanding and contracting in all directions at the same time.
You are right. Knowing an equation is never enough. You must know what those expressions are intended to explain. We do know what that thing is that forces us to the ground. We call it gravity. That is the experience we recognize when all of existence is pressing down on us from heaven trying to return to the nothing it wants to be.

Gravity pulls us down the same way as the apple fell to the earth. Without it, we would all float away. Yeah Earth's core is pretty hot...with all that MAGMA! ;) The Sun has a magnetic pull to it as well! It also has a crust, mantle and core just like the Earth only our planet is cooler so we can survive on it!

Magnetic pull. You need to understand a bit of geology to understand the effects of gravity.
Earth is made up of 3 nested spheres, namelly:
1. Core, 2. Mantle and 3. Crust.
Each layer is composed of many minerals and metallic elements, which by course of time, act as a huge magnet. As you know all the organisms, living and non-living have metallic composition within. Thus the gravity comes into picture.
