How do we know that nothing can travel faster than the speed of light?
Why we cannot make a vehicle which can move at a speed greater than the speed of light?
We are travelling at light speed according to photons. But we shouldn't be able to reach the speed of light, so why does this happen? Speed of Light: How fast can we move? What happen if we moving with the speed of light? Why is that there is no limit for acceleration but limit for speed (speed of light)? Special Relativity: What would stop someone accelerating beyond the speed of light if they had achieved 99.9% of the speed of light? Why does driving at 60mph in a sedan feel faster than the same speed in an SUV? When a motor vehicle speed is limited by law, then why do manufacturers design cars that can go significantly above that limit? What happens to an object if it reaches the speed of light? Why do cars let you go over the speed limit? Why do we assume that travelling faster than the speed of light necessitates time travel? If an object could travel at the speed of light, what would happen to it? What would happen if we travel at the speed of light? What would happen if an object would reach the speed of light? Why is the speed of light not infinite? What would happen if I travel with a speed of light? If you could travel the speed of light, what would happen? Why and how speed of light is not relative? (see details) Why isn't acceleration of cars limited? What would happen if someone ran faster than the speed limit? Why did Einstein assume that the maximum possible speed is the speed of light? Why does light travel so fast? Why does mass increase with velocity as an object approaches the speed of light? Why speed = distance/time? If a car could travel the speed of light what would happen when you turn the headlights on? If a car travels at the speed of light, will its headlights travel at twice the speed of light? Do cars with bigger wheels travelled fast than those with smaller? If in theory an object reached the speed of light what would happen to it? Why can humans feel acceleration, but not constant speed? Why does everything with time slow down as one travels close to the speed of light? Is the speed of the amplitude of light faster than light?
