Description

Speed of Light in Vacuum (c)

The speed of light in a vacuum, denoted as 'c', is a fundamental physical constant valued at approximately 299,792,458 m/s. It is the upper limit for the speed at which information or matter can travel, according to Einstein’s theory of relativity. This velocity is pivotal in physics, cosmology, and electromagnetic theory.

Third Cosmic Velocity (v3) – Solar System Escape

The third cosmic velocity, around 16670 m/s, is the speed required for an object to leave the Sun’s gravitational influence from Earth's orbit. It's relevant in interstellar travel and deep-space missions, marking humanity’s reach beyond the solar system. Only a few missions, like Voyager, have achieved such velocity.
