There are energies of different characteristics. I do not mean kinetic energy or static energy.

The Speed of Light and How to Define speed? by Sherif S. Monem sherifsmonem

In physics when it is hard to define a subject you try to define it in terms of other undefined subjects and this what makes science great. Such a case is to how to seek and define speed of light? In order to define the speed of light one needs to define what is the distance? and what is the time in absolute sense? I our daily life and on planet earth measuring distance and time we can measure these two terms in close absolute certainty but this is not the case in cosmos and in between planets in the solar system and in between the stars.

Michelson–Morley experiment Limitation and Speed of Light BY Sherif S. Monem

The limitation of Michelson-Morely experiment and deduction that speed of light is constant is encountered that the experiment is performed in uniform gravitation field. This would not be the case where there is gravitation gradient and travelling at vast distances.
