So, if the speed of light appears to reach the observer at the same time no matter the observers velocity, then does that mean that light from the nearest star reaches us just as quickly as light from the farthest galaxy?

The speed of light is measured using a unit called meters per second (m/s) or kilometers per second (km/s). It is typically measured by using a device called a laser interferometer, which measures the time it takes for light to travel a certain distance.
The speed of light in a vacuum is approximately 299,792,458 meters per second or 186,282 miles per second. This is considered to be the maximum speed at which anything in the universe can travel.
The nearest star to Earth is Proxima Centauri, which is located approximately 4.2 light years away. This means that it takes light 4.2 years to travel from Proxima Centauri to Earth.
The farthest galaxy from Earth is GN-z11, which is located approximately 13.4 billion light years away. This means that it takes light 13.4 billion years to travel from GN-z11 to Earth.
No, according to Einstein's theory of relativity, nothing can travel faster than the speed of light. This is considered to be a fundamental law of the universe and has been supported by numerous experiments and observations.
