what is the speed of light in mph
As an object approaches the speed of light, its mass rises precipitously.
If an object tries to travel 186,000 miles per second, its mass becomes infinite, and so does the energy required to move it.
For this reason, no normal object can travel as fast or faster than the speed of light.
How fast is 100% the speed of light in mph?
