A sonic boom occurs when an object exceeds the speed of sound, leading to questions about whether a "gravitational boom" would form if an object surpassed the speed of light. The discussion clarifies that while light can slow down in different media, no massive object can exceed the speed of light in a vacuum. The concept of Cerenkov radiation is introduced, which occurs when particles travel faster than light in a medium, creating a Mach Cone of light. However, it is emphasized that massive particles cannot reach or exceed the speed of light, and thus a gravitational wave cone cannot be formed. Ultimately, the speed of gravity is equivalent to the speed of light in a vacuum, reinforcing the impossibility of surpassing this limit.
