“In universal law of gravitaion what is the word “attraction” actually refers to?
I am already on the earth surface and attached to it.Then what is the meaning that earth still attacting me accounts for.
Does that mean earth want me to attarct me towards its center point (ie.., into the inner core of the earth’s interior).
Please answer I am puzzled and worried about my analysis.
Explain with reasons…”
Asked Gopi Krishna
Yes, Earth continues to attract you until you reach its centre.
Every body attracts all other objects towards its centre, not to its surface!
First, I am a physics ‘hobbyist’; I have only rudimentary (read college classes) in physics and I absolutely recognize that I know very little about the subject except what I have studied and can find online. However, I have a theory that the flow of time causes space in much the same way that the flow of electricity causes magnetism (the ‘right hand thumb rule’, for example). This would explain the supposed curvature of space since it would flow in a circular motion nn degrees against the flow of time. This idea could explain, in a way, the faster-than-light expansion of space nanoseconds after ‘The Big Bang’ since it wasn’t space that exploded but rather time that exploded meaning time ‘flowed faster’ immediately after the big bang causing a massive, near instantaneous expansion of space at that time. (As you can see, I have far too much ‘time’ on my hands…) The problem I have – and hope someone can answer – is that I can think of no way to prove or disprove this experimentally; not so much my ancillary thoughts of time and the big bang but rather if time causes space, how can this be disproved or proved experimentally?

“Is the acceleration due to gravity different in south pole and north pole?”
As per theory, acceleration due to gravity changes with altitude, depth and latitude.
If we consider that the variation of g with latitude is caused by rotation of earth only, then the value of g will be same for both north pole and south pole.
But, the change in the value of acceleration due to gravity with latitude is caused by the shape of earth too. So it depends your distance from the centre of earth when you are at north pole or south pole.
For calculations the polar radius is taken same at North as well as south pole. So, value of g can be taken the same for both poles.
