The speed of light is arbitraily determined; that is, it was initially defined in terms of a standard measurement, the metre, but is now the basis for its own measurement (the definition of a metre having changed to be 1/299792458 of the distance light travels in one second and the second determined by the vibrations of a particular species of atom). Thus its speed is known exactly, because that is the definition of the units it uses.
What else can I help you with?
Who are the scientists who calculated the speed of light?
Ole Romer
Is there a tool for measuring the speed of light?
No, but the way that scientists measured the speed of light was having a group of scientists stand on two mountains within visibility, then one group flashes open a light or lantern and they count how long it takes to reach the other mountain using a stopwatch. Then they subtract human reaction time to the equation and do some simple equation using the time they counted to find the speed of light.
When did scientists attempt to measure the speed of light?
Are you asking when the speed of light was first estimated, or are you asking when the speed of light was first actually measured?
Who broke the speed of light?
Nobody did, as far as we know.
What did Aristotle contribute to the discovery of the speed of light?
Aristotle did not directly contribute to the discovery of the speed of light. The speed of light was first measured by Ole Roemer in the 17th century using observations of Jupiter's moon Io, and later refined by other scientists. Aristotle's work primarily focused on natural philosophy and did not extend to the study of light and its speed.
Do scientist study other galaxies because they want to learn about the speed of light?
No. We already know a good deal about the speed of light. Scientists study other galxies to learn how galaxies work.
Who are the scientists who calculated the speed of light?

Why do scientists measure light intensity?
to know how is the light heavy
How can scientists create a portal to a parallel universe?
Scientists do not know how to create a portal to a different universe. They don't even know if it is possible. Alternate universes are merely theories. In the television show The Flash, they are working on this and it may take Flash traveling the speed of light.

How do you make a timemachine?
the only way i know how to time travel is that if you started at earth and went for a huge distance traveling at the speed of light (299,792,458 meters a second or 186,282 miles per second) then when you come back to earth you would have traveled in time. But the problem is we have nothing that can go near the speed of light and a lot of scientists say absolutely nothing can go faster then the speed of light.
How do they time the time it takes for the light coming from the sun to reach the earth?
Scientists measure the time it takes for light to travel from the Sun to Earth using the speed of light. They know the distance between the Earth and the Sun and divide it by the speed of light to calculate the time it takes for sunlight to reach us. The speed of light is approximately 186,282 miles per second (299,792 kilometers per second).
Is the earths orbit faster than the speed of light?
We know that the answwer must be "No", simply because we know that NOTHING is faster than the speed of light.
Is the bullet train faster than the speed of light?
No, not quite. We know that for sure, because nothingmoves faster than the speed of light.
Why do you measure distance in the universe in light years?
It's the fastest speed anyone can prove exists. Any speeds in excess of light speed are still just theory. Some scientists believe it is the fastest speed that will ever be achievable.( a cosmic speed limit.)
How do scientists measure distance in space?
Scientists measure distances in space using a variety of methods, including parallax, radar ranging, and analyzing the light emitted by objects in space. These techniques allow scientists to calculate distances based on the speed of light and the time it takes for light to travel between objects.
