Its no problem, its well understood..
Just a note, the speed of light is only constant in vacuum. If travelling through various mediums gas, water, liquid sodium etc it's speed reduces considerably.
Around 23 years ago scientists succeeded in reducing its speed to around 38 miles per hour by passing laser light through extremely cold liquid sodium.
Scientists slow speed of light to crawl; research had Stanford underpinnings
When light travels through other mediums, besides a vacuum, we will get the honey bee affect. Honey bees do not go from point A to point B, directly. They will stop along the way to smell the flowers. This will take longer than expected to get to point B.
When light bends going from air to water, the second longer path is connected to the meandering of light among the flowers; water molecules. Light would be hard pressed to miss every atom in a dense medium, like it can in a vacuum.
Relative reference is well understood. However, most theory in cosmology and astral physics does not have a relative reference disclaimer, attached, so the layman does not just assume these theories are good for the entire universe.
The work around this limitation for the heavenly sciences is to use Einstein observation that the speed of light is the same in all references. If we used the speed of light as the frame of reference, for all heavenly science observation, we could say we now have universal theories, without the need for any relative frame disclaimers.
A few years back I developed a theory that the speed of light reference, was the ground state of the universe. I called it the ground state because the forces of nature spontaneously head in that direct. Gravity, for example, curves space-time in a direction toward the speed of light; more and more curved. The speed of light frame is finally achieved by black holes; time and space become points.
The forces of nature begin with inertial matter. As they act they will give off energy; photons, that travel at the speed of light. We constantly see a partial conversion of inertial matter back to the speed of light ground state; photons. The sun uses gravity to induce fusion with a lot of c reference generated; light.
Currently, we treat the speed of light like a ceiling, but is is actually more like the floor of universe, as inferred by the direction of potential flow via in the four forces. If we used up all the potential in the four forces connected to matter, we would have only energy and a speed of light frame.
Photons travel at the speed of light, but they also show finite attributes that we called wavelength and frequency. If use Special Relativity, and we traveled neat the the speed of light, all measures of time would dilated become. Photon clocks; frequency, is not homogenized by the speed of light. Photons are not fully in the speed of light reference, but have two legs, with one leg in the inertial frame; stays finite.
The expansion of the universe, by causing a red shift is there to lower the value of the inertial legs of emitted photons; longer wavelength means less inertial energy potential per photon. This is consistent with the speed of light floor; pure speed of light reference without any space-time addendum. The Big Bang was the ceiling of the universe and since then we are heading back to the ground state at c.
