How close are we to achieving the speed of light?
To summarize, according to the immutable laws of physics (specifically, Einstein’s Theory of Special Relativity), there’s no way to reach or exceed the speed of light.
Is it possible to go faster than the speed of light?
No. The universal speed limit, which we commonly call the speed of light, is fundamental to the way the universe works. Therefore, this tells us that nothing can ever go faster than the speed of light, for the simple reason that space and time do not actually exist beyond this point.
Why can’t anything move faster than the speed of light?
Consider this… the speed of light is 300,000 kilometers per second (186,000 miles per second) and when an object moves at this speed, its mass will become infinite. Therefore, infinite energy will be required to move the object, which is impractical. That’s the reason why no object can move at the speed or faster than the speed of light.
What if an object travels at 90\% of the speed of light?
On the other hand, if an object traveled at 90\% of the speed of light, then its mass would be 2 times its original mass. Can we travel at the speed of light? No, we cannot travel at the speed of light. You see, if an object travels at the speed of light, its mass will increase exponentially!
What is the relationship between speed of light and mass?
It means that if an object moves at a velocity that is 10\% of the speed of light, then it would experience an increase in its mass by 0.5\% of its original mass. On the other hand, if an object traveled at 90\% of the speed of light, then its mass would be 2 times its original mass.
What is the speed of light in a vacuum?
The theory of special relativity showed that particles of light, photons, travel through a vacuum at a constant pace of 670,616,629 miles per hour — a speed that’s immensely difficult to achieve and impossible to surpass in that environment.
