Willusions.
Henry Wilson DSc
Here on Earth, we mainly EM for that purpose and because of its enormous speed
compared with those of the objects we observe, we normally don't have to worry
about willusory effects. As far as we are concerned, what we see Is a true
replica of what actually happens. At least that was the case before the advent
of the GPS system, in which a correction has to be made for the acceleration of
light as it falls to receivers from different orbit heights.
In the case of sound, a medium is involved and willusions don't normally occur,
conventional doppler shift being just an indicator of relative speed.
However there is one good example of a sonic willusion with which everybody is
very familiar.
THUNDER!!!!!!!
A lightning flash is over in milliseconds yet we hear its sound for maybe ten
seconds. Why? Because the atmosphere is very turbulent under a storm cloud and
features large temperature and pressure gradients. Sound from the upper
sections of the flash travels along a variety of paths and at many speeds
before it reaches any particular point on the ground. The result is a long
rumble of varying strength and quality. Thunder is a perfect example of a
willusion. In the absence of lightning, a similar sonic outburst would attract
all kinds of weird explanations from the scientific witchdoctors
Light from a distant star travels across space in fairly straight lines.
However, its speed relative to planet Earth will vary whenever its source speed
changes. Hence, as with thunder, light from for instance an orbiting star will
arrive at planet Earth in cyclical bursts giving an impression of varying
brightness.
Because willusions are foreign to our everyday experiences, most humans and
paticularly relativity supporters, don't have sufficient intelligence or
imagination to understand that they actually exist and are in fact a common
feature of all astronomical observations.
Thunder was once believed to be a sign of godly anger. The way in which
astronomers try to explain star brightness variabillity is often no less
ridiculous.

Wilson thinks thunder will arrive at planet Earth in cyclical bursts.
There are two types of xmas prezzies. Those that are given by
friends and family and those that are genuinely brought by Santa.
"Even in their ignorance, astronomers recognize two types of cepheid.
I suggest that some are genuine huffpuffs [Santa given] with a short
period and the others are mainly stars with an orbiting companion." --Wilson

...as well as the speed difference with respect to the ground, an effect
familiar from special relativity. Which, as you may recall, you don't seem
to have an explanation for.

Wowzers.
You really don't know much about anything, do you?

And yet somehow this 'bunching' of starlight is not observed.

Yet someone who doesn't do any experiments nor reads any literature has
perfect command of something nobody else has ever seen. Gotcha.

You, obviously, have never had to talk to somebody across the seas using
a half-duplex phone line.

If you have an example of a willusion please tell us about it.
I use a voip phone and don't have any willusory problems.

Sound and speed of light are slow. Admiral Grace Hopper talks about
the latter when she told the story of explaining toit a military higher
up. One of these talks is on-line somewhere.

That's because of error checking.

I don't think your example decribes a willusion but it might be something
similar.

It takes 8 seconds for the sun's light to reach the Earth. Where is
it being checked for errors?

I know you meant 499 seconds (on average).

minutes
where does 'half duplex' enter into this argument?

Thanks for the correction. :-) My head was thinking about
microseconds, so my fingers translated inappropriately :-).

Yep. goofed it up. Thanks.

It was an example I encountered which taught me that sound and
electricity was slow.

You really should look for it. It's very entertaining.

Electricity isn't slow.
However many computer signals are sent forward then backwards again for error
checking (or something like that).

Which shows you don't know what you're talking about. What computer
signals are you talking about? You don't know, do you?
Again, I recommend you view Adm. Hopper's talk.
