Reinstall the front wheels and lug nuts and lower the car to the ground. Once the vehicle is at a normal riding height, torque the lug nuts and control arm mounting bolts according to their proper torque.
Gravity is a function of mass. It is the enormous gravitational influences that causes nuclear fusion within stars. Explanation: If you accept, as you must, that gravity is the causal factor of nuclear fusion in all stars then you can infer by extension that the larger the star, the greater the mass; the greater the mass, the greater the gravity; the greater the gravity, the faster the rate of nuclear fusion.
Another scenario that could cause earth to eject from its orbit is our solar system passing closely by another star or body of significant gravity such as a black hole. Considering there are estimated to be over 300 million stars in the Milky Way Galaxy, it's hard to say this not possible.
