Wht Cause the Gravity ??
- Thread starter Y2K
- Start date
Unknown yet. Somebody says its gravitons (gravity particles something like gluons in nuclear particles) or gravity waves. OR spacial curvature. But nothing confirmed yet.
But I just want to know whther the reason for gravity is Motion or Rotation of the earth coz one of my friend says that he thinks that its b'coz of the rotation
As far as I know...
There is no universally accepted answer regarding what causes gravity. Though we understand the effects of gravity, exactly what causes it is not yet exactly known to the scientific community, let alone us folks.
Gravity is NOT affected by the rotation of the earth, as far as I know. What your friend might be saying is that there are claims that gravity is due to the rotation of the galaxy. However, arguing on these things are useless as they involve quite advanced physics, which only a few people in the world can understand.
What grade are you in? You will learn about Newton's Theorem of Gravitation in your A/L s if you do physics.
Newton says that any two bodies are attracted to each other, and the force of attraction is directly proportional to the product of the masses of the two objects and inversely proportional to the distance between them. Rotation speed does not come into the equation.

So, what does this have to do with gravity? It is quite simple! When a mass is present in the above space-time it distorts it so that whilst it remains true that travelling through space causes you to travel through time, travelling through time now causes you to move (accelerate) through space. In other words just by existing, you are compelled to move through space - this is gravity.
