The universe has a cosmic speed limit
Light speed, approximately 299,792,458 meters per second, is the universe's ultimate velocity, a fundamental constant that nothing with mass can surpass.
Nothing in the universe can travel faster than the speed of light in a vacuum, a fundamental constant denoted as 'c'. This cosmic speed limit, roughly 299,792,458 meters per second (about 186,282 miles per second), was famously theorized by Albert Einstein in his theory of special relativity. As an object with mass approaches this speed, its mass increases infinitely, requiring infinite energy to accelerate further, making it impossible to reach 'c'.
