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.
The explosion of the star creates a shock wave that compresses nearby interstellar clouds. Yes. When the material from the explosion encounters an interstellar cloud, it creates a shock wave in the cloud that compresses the cloud very suddenly. This sudden compression can initiate star formation in the cloud.
