Here's what Einstein's theory of special relativity actually says:
* The speed of light in a vacuum is constant for all observers, regardless of their own motion. This means that no matter how fast you're traveling, you will always measure the speed of light to be approximately 299,792,458 meters per second.
* Nothing with mass can travel at the speed of light. As an object approaches the speed of light, its mass increases infinitely, requiring an infinite amount of energy to accelerate further.
* It's theoretically possible to travel faster than light, but this would require exotic matter with negative mass, which hasn't been observed. This hypothetical phenomenon is called "superluminal travel" or "faster-than-light travel."
So, Einstein's theory does not suggest that we can travel faster than light, but rather that it's impossible for objects with mass to reach the speed of light.
