👉 In physics and mathematics, "supereffective" is a concept used to describe a phenomenon where an object or system can achieve a state of superluminal speeds. This means that the object or system can travel at greater than the speed of light but still remain in a state of constant motion. This concept is often associated with black holes and neutron stars, which are thought to be the source of superluminal phenomena such as gravitational waves and the phenomenon known as "the black hole's
