that’s the law of inertia based on newtonian physics than einstein’s theory of relativity.Those with high IQ please enlighten me here :
If I were to hop at the front of a moving bus, aka at the driver side, a few hops on the same spot should technically send me to the back of the bus immediately because the bus is moving, right ? So why am I still hopping on the same spot ? Why is gravity in the moving bus and gravity outside different ?
To an outsider, I am moving because the bus is moving. But I am still hopping at the same spot inside the bus leh. Why?
Any physics affacionado here care to explain ?

the basic law of inertia can fully sexplain this phenomenon. don’t need the theory of relativity yet. einstein’s theory more cheem and can solve deeper questions.Still dealing with gravity and time, so it's still relativity.
You have set yourself a very deep problem in time and motion physics. You are "hopping" in a bus that is moving on the road and planet earth is rotating and orbiting the sun which is moving in the aether (vacuum gas) medium of space and our galaxy may be rotating wrt other galaxies... Few people can answer this question well.Those with high IQ please enlighten me here :

That's exactly the point I bringing out. It seems every object has its own gravity and its own relation to time.Try setting yourself a more elementary problem. Our earth is orbiting the sun at about 30km/sec (how's this speed as compared to your car speed 100km/hr?). Why is that you standing on the planet earth don't get "fling" away towards outer space?
When the Americans landed on the moon, they were not "flung" away into outer space. The moon does not rotate on its own axis, only orbiting around the earth. So no counter-balancing forces.That's exactly the point I bringing out. It seems every object has its own gravity.
My take on why we're not flinging away is probably the earth is rotating on its own vertical axis as well as traveling in a horizontally circular trajectory around the sun and those two opposing motions somewhat cancelled out each other, keeping us rooted to the ground. I supposed once earth stopped rotating on its own axis, then we're all be flung into space at terminal velocity immediately.
Appreciate your answer but please don't stop me from asking deep questions. I think I'm entitled to that privileges unless you're some sort of authority to stop me, which you obviously are not.
NASA doesn't agree with you on this one.When the Americans landed on the moon, they were not "flung" away into outer space. The moon does not rotate on its own axis, only orbiting around the earth. So no counter-balancing forces.

Same reason as hopping on a flying plane. You are already moving at same speed as the transport.Those with high IQ please enlighten me here :
