What Happens When Speed Exceeds Light? Causality and Paradoxes
New ReviewSummary: If you point a powerful laser at the moon, and spin it 100 times per second, the dot on the moon will move 3X the speed of light. This is ok. The maximum speed limit is not a limit with which things can move, but is a limit on...

What Would Happen If You Traveled At The Speed of Light?
If you travel at the speed of light, your mass will increase exponentially. The speed of light is 300,000 kilometers per second (186,000 miles per second). When you move at this speed, your mass will become infinite. Therefore, infinite...
