well this might sound crazy but the person/people who actually went at the speed of light is aliens in ufos because there way more complex than us humans so they are able to surpass us in speed
Light speed is the fastest known speed.
It is known as a light year.
i dont think there is one
It is known as a light year.
the speed of lightspeed of light
As far as is known nothing with mass can travel at the speed of light. There are 'things' that exceed light speed, such as wave guides, but mass or information cannot do so.
Assuming the speed of light in air is already known (it is close to the speed of light in a vacuum), you might check how the light refracts when it changes from air to water (at what angle), and then use Snell's Law.
The speed of light remains constant regardless of the motion of the observer or the source of light. This principle is known as the constant speed of light in a vacuum, as described by Einstein's theory of relativity.
No, according to current scientific understanding, light travels at a constant speed in a vacuum, known as the speed of light, which is approximately 299,792 kilometers per second. This speed is a fundamental constant of nature and cannot be exceeded by light or any other object.
299,792,458 ms-1 also known as c / speed of light.
Light waves in space travel at about 186,282 miles per second or approximately 300,000 kilometers per second. This speed is constant and is known as the speed of light in a vacuum.
Light does not accelerate. In a vacuum, light always travels at a constant speed of approximately 299,792 kilometers per second, known as the speed of light. It only changes speed when it passes through different mediums.
