Observations of Jupiter's moons provided the first real evidence that light had a speed and wasn't instantaneous. Essentially, the orbit of Jupiter's moons was known fairly accurately over the short term, but over longer time periods (a few months) the moons appeared to lag behind or speed ahead of their predicted positions. Eventually it was realized that this was because the Earth-Jupiter distance changes as they orbit the Sun, and the difference was due to the extra time the light required to reach us when the distance was further.

∙ 12y agoThe speed of light was predicted, by J. C. Maxwell, before it was measured.
Modern measurements began around 1860. The better the measurements
became, the closer they came to the speed that Maxwell predicted.

Is sound the fastest speed possible?
No!...Speed of light is the fastest speed possible, but now a new particle called lepton is more faster than light...rather it is has the fastest speed discovered till now.It travels in the same wave as light travels i.e tranverse waves.
Who discovered that the electric current flows at the speed of light?
A german physicist named Gustav Robert Kirchhoff was the first scientist to show that eletric current flows at the speed of light through a conductor.
What did Isaac Newton discovered about light?
he discovered that light has 7 colours
Is it light speed or the speed of light?
speed of light I think well it sounds right:)
Is it possible to travel at the speed of light in water?
The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
What is Michelson famous for?
he discovered the speed of light
Why is light speed the ultimate?
This is because nothing else in the entire discovered universe moves as fast as the speed of light!
Who discovered the equation energy times speed of light squared?
Einstein
Who was the first to find the speed of light?
it was MAxwell the dude who discovered electromagnetic waves
What did Olaus Roemer invent?
Olaus Roemer discovered the speed light in 1676.
What can be discovered if something is found which has greater speed than light?
probably all kinds of technology
Is sound the fastest speed possible?
No!...Speed of light is the fastest speed possible, but now a new particle called lepton is more faster than light...rather it is has the fastest speed discovered till now.It travels in the same wave as light travels i.e tranverse waves.
Who discovered that electromagnetic waves can travel through empty space at the speed of light?
James Clerk Maxwell.
Who was the scientist who discovered that heavy and light body of the same substance fall at the same speed?
Galileo I think.
Who discovered that the electric current flows at the speed of light?
A german physicist named Gustav Robert Kirchhoff was the first scientist to show that eletric current flows at the speed of light through a conductor.
When was speed discovered?
The second species in any environment.It was either a predator and wanted to move faster than the first to catch and eat it, or it was the prey and wanted to get away! So several millions of years before the first humanoid.
How did Albert Einstein determine the speed of light?
Albert Einstein did not determine the speed of light, rather that the speed of light was the maximum speed possible in the universe. The speed of light was discovered in the late 1600's by Danish astronomer Ole Roemer, using Jupiter and its moon Io. It was later used in Maxwell's equations of electromagnetism, and then later used by Albert Einstein in his theory of special relativity.
