Michelson and Morley: Four Time Failures?
In the late 19th Century, two men tried to find out how fast the ether wind blowing through our Universe was going.
Michelson was particularly confident of his abilities, for he had done much to determine the speed of light already.
Ether was the substance that it was thought to have to exist in space, so that the "wave" of light would have something to go through, much like air is needed for a sound wave to go through.
The experiment was based on measuring the speed of light and seeing how much faster or slower it went when it was going "upstream" or "downstream" relative to the ether winds.
Here is a link:
Flashlet of the experiment!
So you know, set the ether wind for as fast as you can, for full effect. Obviously when the light is split into two beams, one will have it's speed shifted by the ether wind more then the other will.
And they will not be in sync when they are reflected back.
The discrepancy will tell you the speed of the ether wind, which was all the experiment was trying to find, for they "knew" ether existed.
Yet.
Set it at zero speed, and watch the light split...then rejoin in perfect sync.
This is what happened the first time, leaving two very puzzled scientists. Nothing happened. No difference. Given that their math already told them what the difference was supposed to be, this is where government defense scientists would just publish that and be done with it.
These two assumed that they had not worked hard enough. That the speed was smaller then they thought. That they needed more accurate instruments, more elaborate procudures.
So they did all that. And tried again.
And failed.
Leaving two very frustrated scientists, for they did know their own worth. Or had thought they knew it. This is where a University research team suggests that it is "unfeasible to continue at this time" and wanders off in search of a defense grant.
These poor guys. They knew ether was there! So they came up with an elaborate theory that would have ether cling or puddle on the earth, much like air can puddle.
And after much more work and development, went out to California, found a real high mountain, and conducted the experiment on top of it! In the 19th century!
And failed! A third time.
This might be where even a crack company research scientist might think about filing this in the "circular file", and quietly moving on.
They published. They published their complete and utter failure.
They didn't give up though.
Now, they figured, okay, maybe there is no ether. But light is still moving...relative to what? If not ether, what is the light speed relative to?
And decided that it was relative to the source that emitted the light, much like bullet's speed is relative to the source, the gun.
And they set up experiments to determine that.
And they failed. For the fourth time! The light was not relative to the source of the emissions.
And they published that, too.
So what was the point of the lives of these four time failures? Well, in science, even a disproving of something is a bit of data. And these two had rather thoroughly shown everything that light speed is not relative too. Which allowed a certain patent clerk named Albert Einstein to realize in 1905 that the speed of light was a constant!
And that all else was relative to it!
Would he have discovered that, without knowing of their work? Doubtful, and certainly not so soon. Modern Physics would have been delayed, perhaps fifty years. Or given the scarcity of men like Einstein, our chance might have passed us by for discovering Modern Physics, and we'd yet live in the world of classical physics.
A world where instead of WWII ending when it did, the Japanese killed 50,000 more of us as we fought for every inch of Japan. Where China stomped us in the Korean war. Where Russian and America fought war after war, decimating our cities and farms conventionally, since there were no nuclear weapons to deter.
A world where we we had no orbiting satellites beaming down information and weather patterns and phone calls. No moon trip. Higher costs for power. No nuclear medicine.
And who knows if we'd have won against the Soviets, or made a peace that bore resemblence to surrender?
Or both been so decimated as to give fresh opportunity to China, Japan or Germany?
Actions have consequences, and the actions of these two unsung heroes loom large. They followed all scientific rules. All procedures. They were meticulous in their planning, in their theories, and most of all, in their honesty.
They never doubted reality. They doubted themselves, their work, their interpretations...but never reality. Yes, ultimately they were wrong, there was no ether, light was relative to nothing. But you get so much further working to correct what you can, to do what it is in your power to do, rather then complaining that the Universe is not acting as it is "supposed" to!
They were true Scientists, and their names deserve to be remembered.
