Perhaps, but Han Solo made the Kessel Run in 12 parsecs.
It is very difficult to know for certain that basic constants (like the speed of light) have always been the same or are the same everywhere in the universe...
Did you hear that on TV? Did you lose interest, yourself? If you did, how much of it was because you were told everyone else lost interest?
Attention span is a by-product of conditioning. Virtually all mass media is for the purpose of conditioning. Conditioning is done beneath the intellect.
In short, don't watch TV. Your intellect may rescue you from prior conditioning with great effort, but you have stop pouring it over your head first.
No, radar and optics electronics still would work. Work is the key term.
As explained in the video, even Einstein admitted that c was a convention, a working solution. And, even today, we cannot compute the one- way value of c, except by dividing d +d1 by 2. The speed of light is an Ave age, and an average doesn’t require equality of values..... 1.75 + 1.25=3/2=1.5. but 1.5+1.5=3/2=1.5 is not the same as the former equation, although the answer is the same.
Since we cannot overcome the variables presented, like time dilation, or clock speed, we cannot using technology compute the speed of light in one direction. Therefore, c is defined by convention as 186k mi/sec and it works for our purposes, as we can clearly agree.
Dean,
You touch on oneajor issue modern science is stuck on, Uniformitarianism. The idea and belief, absent observation and test, that processes, values and measurements have always been constant. This idea has very little fact involved. Today, tectonic plate movement may be x, but 10k years ago, or more, it may have been x*2,
Which is just as valid an assumption as a uniform process....
We all have the same facts and evidence, it is the lens that we choose to observe or assess with that determines the answers we arrive at.
I happen to hold a biblical world view, so my lens is not as liberal or free as a non believer. IOWs, I look at things through the lens of both observation where possible, and description where applicable. I have not found incongruences that are beyond acceptance.

The answers to your questions are no, no, and no.
I was required to live through it.
And I also listened to a great many individuals, across a wide cross-section of society. I’ve always had a talent for listening; we can learn more that way. Let me emphasize the word “can;” there aren’t any guarantees.
You’re hinting at conspiracy theories. Theories are belief, not knowledge. Knowledge beats belief every time.
Yes. In quite a few things, our baseline is short.
We only have real temperature measurements for a little more than a century, in very limited areas, for example.
Gravity measurements are pretty short term.
Speed of light measurements about a hundred years.
If there is gradual change over millenia, we are hard pressed to measure it.

If you’re asserting that we cannot compute the speed of light *exactly*, I concede the point.
But that degree of exactitude can only be found in the realms of theoretical physics, mathematics, and philosophy. All three fields display a common flaw: practitioners seem afraid of reality - even as they insist their fields of expertise are somehow superior to, or at least prior to, reality.
I realize that the speed of light in a vacuum is not exactly 299,792,458-point-something meters per second, but nine significant digits might be enough to unscramble a whole bunch of everyday problems.
I wasn’t smart enough to attain an engineering degree, but in professional life I was required to work closely with engineers, and theoretical physicists, and mathematicians (but darned few philosophers). We were always buried in practical problems urgently in need of solution, and it was essential to get the various working-group members oriented, motivated, and toiling. A struggle that never ended.
Eventually, it dawned on me that the preoccupations of the “experts” with were not that relevant to the grubby real-world situations at hand. I gave up kidding myself, that we needed to compute the value of c past yet another dozen significant digits, or discover a Higher Truth, to do our jobs.
I remember as a teenager staring up at the moon in 1969 and realizing there were men on it. Why can’t I do that today?
It’s blatantly implausible that we stopped the manned space exploration program because we simply “lost interest”.
Imagine if everything west of the Mississippi was still unexplored by Americans even today and you were told the westward expansion stopped because Americans “lost interest” in exploration. You wouldn’t believe it and you would know something else is keeping us out.
C=(d1+d2)/(t1+t2) but we know that we cannot use two clocks to generate the time each way without violating basic relativity. So, one clock is used and elapsed time is determined for the round trip, so time is an average. An average doesn’t require equality. Cannot prove that time is of uniform speed in both components of d because you’d have to be able to use both time segments measured independently but current technology and physics says otherwise.
If declaring c as a convention satisfied Dr. Einstein, I’m okay with it, and for practically all of our needs, it works just fine.
