Wrong. Einstein did not have the power to force the speed of light to be absolute, "by definition", or any other means. The speed of light is a Lorentz scalar because that's what it is measured to be. Further explanation: If I decide to force two clocks to obtain one-way light ...

titled "On the Electrodynamics of Moving Bodies",Albert Einsteinasserted that the speed of light in a vacuum, measured by a non-accelerating observer, is the same in all inertial reference frames and independent of the motion of the source or observer. ...
lidar experimentWith the aid of modern electronics the speed of light was directly measured by timing the delay of a light pulse from a laser in reflecting from a mirror in experiment performed in educational Physics Laboratory.doi:doi:http://dx.doi.org/Krassimira Kardjilova...
What are the basic si units for the speed of light? How can you find the speed of light using an equation? How was the speed of light discovered? How did Albert Michelson measure the speed of light? What unit is light energy measured in?
In the 18th century, Ole Roemer calculated the speed of light by observing the eclipses of Jupiter’s moon, Io. In the 19th century, James Bradley measured the speed of light by observing an aberration. In the 20th century, Froome calculated the speed of light by using laser interferometers...
How was the speed of light first measured? In 1676 the Danish astronomer Ole Christensen Romer made the first quantitative measurement of how fast light travels. He carefully observed the orbit of Io, the innermost moon of Jupiter. As the Earth circles the Sun in its own orbit, sometimes it...
Light is often measured as light minutes, particularly in relation to astronomical units. What is the exact speed of light? The exact speed of light is 299,792,458 meters per second. This number can be converted into many different units of measurement, but this is the most common....
One of the first measurements of the speed of light was by Ole Rømer in 1676 by observing themoons of Jupiter. The speed of light was first measured to high precision in 1879 by the Michelson-Morley Experiment. How do we know the speed of light?
