The human is continuously extracting the gas & petrolium product from the internal part of earth surface. Have anybody think over the creation of cavity inside of earth surface, may cause sliding of earth structure or movement of earth or motion of earth around the sun. I feel, It should happen but not able to capture it. Is there any literature over it or is it going blindly because we don’t have the alternative sources of efficient energy.
The earth isnt incredibly likely to collapse. The fluid is pressurized, and below a certain pressure it becomes economically unfeasible to extract the oil. The cavity is still "full".
Some advanced methods involve pumping water into the "cavity" to cause the oil pressure to rise. Again, this isnt leaving a true unpressurized cavity.
Finally, the matter extracted, while large in human terms, is very small in terms of mass of the earth. All that matter was theoretically on the surface at one time, so if putting it from underground to aboveground changes the movement of the earth, then putting it underground in the first place also should have changed the movement.
