How Einstein used the invariant speed of light to overturn a view of space and time that had stood for centuries.
The Strangest Theory We Know Is True
After 99 years, Einstein’s greatest scientific achievement is undefeated.
Faster Than Light
There’s been a couple of questions about the possibility of traveling faster than light, so let’s explore that a bit today. The short answer to whether one can travel faster than light is no. The inertial speed of an object can never exceed the speed of light. This means if you measure the speed of an object passing you, it will always be less than the speed of light. The longer answer is “it’s complicated.”
