Trying to exceed the speed of light clashes with the basic principles of how energy, mass, and time work in our universe. It’s like hitting a universal speed limit that cannot be broken because of how physics and the universe operate.
To understand why nothing can exceed the speed of light, we can think about a few key concepts from physics.
-
Energy Requirements: According to Einstein’s theory of relativity, as an object moves faster and approaches the speed of light, it needs more and more energy to continue accelerating. To reach the speed of light, an object would need an infinite amount of energy. We can’t produce infinite energy, so we can’t reach or exceed the speed of light.
-
Mass Increase: As an object’s speed increases towards the speed of light, its mass effectively increases too. The closer you get to the speed of light, the heavier you become. At the speed of light, the mass would be infinite, which is physically impossible to achieve. This increasing mass makes it harder and harder to speed up as you approach the speed of light.
-
Time Dilation: Another weird effect of moving very fast, close to the speed of light, is time dilation. This means that time actually slows down relative to objects or observers that are moving slower. At the speed of light, time would stop completely. This is difficult to imagine, but it’s a result of the fundamental way the universe works, according to Einstein’s theories.

Space and Time: Light speed is not just a number; it’s a critical part of how the universe is structured. The speed of light links space and time together in the fabric of the universe. This speed is the same no matter how fast you are moving when you measure it, which is unique and different from how we experience speeds in everyday life.
