I don't believe there was any serious attempt to measure the speed of light before
Galileo. That was a couple of millennia after the golden age of the Greek philosopher
'scientists', who, I believe, assumed the transfer of light to be instantaneous, and the
perception of distant events to be simultaneous with the event.
They'll leave your car at the speed of light, and when that light passes anybody, they'll measure the speed of the light as it passes them to be the speed of light.
by getting boners.
In 1600 Galileo attempted to measure the speed of light using lanterns and shutters
Are you asking when the speed of light was first estimated, or are you asking when the speed of light was first actually measured?
speed of light is constant velocity and does not accelerate so there is no g force
Roemer was the first to measure the speed of light.

The Danish astronomer Olaus Roemer was the first to measure the speed of light. (within 25 % of the actual value)

Roughly speaking, light moves about a million times faster than sound in air.
Light is faster because speed does not move. Speed is a measure of the rate of movement but, in itself, it does not move - at all!
The speed of light isn't a distance so it has no length it is a measure of speed, which is roughly 186000 miles per second.
Light travels at about 186,000 miles per second
It doesn't work that way. The light-year is not used to measure the speed of light. It works the other way round: First, the speed of light is determined through other methods, then the distance called a light-year is calculated based on that measurements.
