Airship Rotating Earth: Can it be Done?

In summary, an airship does not have the power to rotate the Earth, unless it is able to make flight path corrections. The Earth's orbit would need to be circular for the airship to be at the center. Mechanical energy and kinetic energy are involved in this process, with the equations E = -MmG/R, Ek = mv^2/2, and Ep = -mMG/r being relevant. It is important to note that the mass of the airship, as well as the physical limitations, play a significant role in the feasibility of this scenario.

If the airship is not powered, no, with the exception that a circular orbit will have the Earth at the center.

If the airship has some power to make flight path corrections, it could do anything it wants as far as the shape of the orbit, within physical limits.

ok so, I read that mechanical energy(E): E=-MmG/R
R=(a+b)/2
a-semi-major axis
b-semi-minor axis
,of course kinetical Ek=mv^2/2
m-spaceship weight
Ep=-mMG/r
v^2/2-MG/r=-2MG/(a+b)
and
a-sqrt(a^2-b^2)=<r=<a+sqrt(a^2-b^2)
and v^2 for some r is less than 0
M>>m

1. Can an airship rotate the Earth?

No, an airship does not have enough power or propulsion to rotate the Earth. The Earth is a massive object with a circumference of over 40,000 kilometers and a mass of over 5 quadrillion metric tons. It would require an enormous amount of force to rotate the Earth, which is not possible with an airship.

2. Can an airship change the rotation speed of the Earth?

No, an airship cannot change the rotation speed of the Earth. The Earth's rotation speed is determined by its mass, gravitational pull, and angular momentum. An airship does not have the necessary force to alter these factors and thus cannot change the Earth's rotation speed.

3. Could an airship affect the Earth's axial tilt?

No, an airship does not have the capability to affect the Earth's axial tilt. The Earth's axial tilt is caused by the gravitational influence of other celestial bodies, such as the moon and the sun. An airship does not have enough force to counteract this gravitational pull and change the Earth's axial tilt.

4. Is it possible to use an airship to slow down or speed up the Earth's rotation?

No, an airship cannot be used to slow down or speed up the Earth's rotation. As mentioned before, the Earth's rotation speed is determined by its mass, gravitational pull, and angular momentum. An airship does not have the necessary force to alter these factors and thus cannot change the Earth's rotation speed.

5. Can an airship affect the Earth's orbit around the sun?

No, an airship does not have enough power or propulsion to change the Earth's orbit around the sun. The Earth's orbit is determined by its mass, gravitational pull, and the gravitational pull of other celestial bodies. An airship does not have enough force to alter these factors and thus cannot change the Earth's orbit.
