But we "see" light traveling across interstellar and even intergalactic distances moving at the present speed of light.
In the case of my avatar, this is a period of several months - 20,000 years ago. For me to make this animated gif I would have to have been "Adam" himself if the "light speed deterioration" theory was true. ******* "The Man" won't let me load my old animated avatar back up. But here's a thumbnail:
Consider: When Voyager 1 was first launched in 1977 it reached the distance of the moon after a couple of days. Its regular radio transmissions took a predictable 1.3 seconds to reach Earth. When Voyager 1 reached Jupiter, it took a little around 35 - 40 minutes for the signal to travel to Earth (depending on where Earth was in its orbit around the sun- 43 minutes to reach the sun itself). Currently its taking about 14.36 hours for a transmission to be received. The space throughout our solar system is predictable in nature and light travels prdictably throughout the solar system.
The eclipses of Jupiter's moons were observed by Galileo and he recorded a strange "variance" in their timing. That "variance" was of course due to the 35 - 40 minute travel time for the light to get from Jupiter to Earth. Today, math wizards with too much time on their hands can go through Galileo's 400 year old observations find the speed of light hasn't changed at all. Looking at my avatar gives proof that the speed of light hasn't changed in the last 20,000 years.
This pic shows that it hasn't changed in the last 167,000 years: A star with a "halo" around it explodes and becomes visible on earth for the first time. Over a period of years the shock waves continue out toward the "halo" of gasses and there they cause rapid compression and the subsequent fire show that we see later.
This is from the Large Magellanic Cloud- a "companion" galaxy to the Milkyway and about 167,000 light years away. The first pic is from 1987 and I believe they go up through 2002. Light travels at the anticipated speeds through "intergalactic space" and we observe no anomolous behavior over the space of 167,000 years.
In the following example- we observe a star going "supernova" close to 10 Billion years ago. And "10 Billion" is a conservative estimate of the distance. We are observing ongoing physical processes across vast distances of space. The smaller objects are known to be galaxies that are more than 12 Billion years ago (and away).
******* Add another note here: The YECs (Young Earth Creationists) will often bring up some recent experiments of "faster than light speed" and "slower than light speed" experiments. In all of these experiments, the change in light speed was only accomplished over very short distances- and I mean very short- micromillimeters. And the effects could only be achevied by passing the laser amplified light through some sort of medium like cessium. Einstein's "constant" (the 'c' in EMC) is qualified to be "within a vacuum." They knew even back then that an intervening medium will effect the light. But Einstein and so many others, can be proven today to be correct- at least for dates up to around 10 or 12 billion years.
I have yet to find anyone, including YECs who will try and say that there is solid cessium between Earth and the nearest galaxy. They just bring up these things and then withold crucial data from you in order to deceive. Sorry, but I've been debating these guys for more than a decade. There's not one YEC (including those with "ministries") on the circuit who hasn't been found out to be involved in some sort of deliberate falsification or twisting of the facts. It's a money making charade. And sometimes it doesn't even take that much money.
