Since everything in the universe is moving relative to the other, how can one measure an absolute velocity? Therefore, how can the speed of light be absolute?

"Photons move at a speed less than c, unless they are traveling in vacuum. "
Did you notice the "vacuum" in my post?
Brainv2.1beta said:Admittedly, I did not notice.
However, there still is the problem that if over 50% of the universe can not be converted into a vacuum then the speed of light is not officially a constant.
I would be suspicious of that article. There's a lot I don't understand, but the author made a big deal out of the variability of G (among other constants) without referencing any of the people who have so long worked on that (e.g. George Gillies). That would be like an article on QED that leaves out Schwinger - you have to ask why?Brainv2.1beta said:

Velocity is a measurement of an object's speed and direction. It is typically measured in meters per second (m/s) or kilometers per hour (km/h). Velocity can be measured using a variety of tools, such as a speedometer or a radar gun.
Yes, it is possible to accurately measure an object's velocity using various scientific methods and tools. However, the accuracy of the measurement may depend on factors such as the precision of the measuring tool and the speed and direction of the object being measured.
Yes, an object's velocity can change over time if its speed and/or direction changes. This is known as acceleration, and it can be measured using tools such as accelerometers.
Air resistance can affect the measurement of an object's velocity, especially for objects moving through air at high speeds. This is because air resistance can slow down the object's movement, resulting in a lower velocity measurement than the object's actual velocity. Scientists must take this into consideration when measuring an object's velocity in real-world situations.
Velocity is a measurement of an object's speed and direction, so for an object to have a velocity, it must be in motion. Objects at rest do not have a velocity, but they may have other measurable properties, such as mass and volume, that can be used to calculate their potential velocity if they were to start moving.
