Why did Einstein conclude that an object with mass cannot travel at the speed of light?
Why did Einstein conclude that an object with mass cannot travel at the speed of light?
- Because light waves would appear stationary to such an object (correct)
- Because Maxwell's equations would be invalid
- Because it would violate the principle of relativity
