Why simplicity works

Does the existence of a multiverse hold the key for why nature’s laws
seem so simple?

It’s May 1964 and, on a low hillside in New Jersey, the physicists
Robert Woodrow Wilson and Arno Allan Penzias are listening in on the
Universe. They are standing beneath what looks like a gargantuan ear
trumpet attached to a garden shed: the Holmdel Horn Antenna, built by
Bell Laboratories to investigate microwaves as an alternative to radio
waves for telecommunication. When interest in microwave communication
waned, Bell lent out the Holmdel horn to interested scientists.

Penzias and Wilson were interested. Both aged around 30, they planned to
map the sky with microwaves. But they were baffled: when they pointed
the horn at a dark region beyond the galaxy and only sparsely populated
with stars, instead of the silence they expected, they detected a kind
of background hiss – a hiss that filled the entire sky.

Meanwhile, the physicist Robert H Dicke was working on a related puzzle.
Two decades earlier, Dicke had invented the microwave detector. Now he
and his lab were trying to develop sensitive instruments to test the
cosmological predictions that emerged from Albert Einstein’s general
theory of relativity, particularly how it related to Edwin Hubble’s
astonishing discovery that the Universe is expanding. The reigning,
steady-state theory claimed that the Universe had always been expanding,
balanced by a continuous creation of new matter. The rival theorists,
including Dicke, took expansion at its face value, running it backwards
in time to propose that, about 14 billion years ago, the Universe burst
into existence in a cataclysmic explosion from a very tiny point.

An exploding universe should have left a uniform faint cloud of
microwave radiation, which Dicke’s team was determined to find. News of
the group’s efforts reached Penzias and Wilson, prompting Penzias to
give Dicke a call. Over a brownbag lunch, Dicke’s colleagues recall him
picking up the receiver, repeating phrases such as ‘horn antenna’ and
nodding. After hanging up, he turned to his group and said: ‘Well boys,
we’ve been scooped.’ Dicke realised that Penzias and Wilson had
discovered the Big Bang....

The reason why this article seems to explain things so simply is that
it has been tremendously dumbed down.

For instance, microwave radiation is:

"Microwave radiation lies close to radio-frequency radiation in the
electromagnetic spectrum, with operating frequencies in the 900–2450
MHz range."

Radio frequencies are otherwise known as infrared light. So,
microwave radiation is really light with long wave lengths.

So, rather than saying that, the author used a phrase that would
arouse little confusion. We all know what microwaves are. Almost all
of us have a contraption for creating such in our houses. Except that
mostly, we do not know that microwaves are really light which our eyes
do not equip us to see. As are radio waves.

So mr physicist, exactly why should the big bang still be emitting
long wave light (why long wave?) so long after the bang?

You say "dumbed down" then use a grade 3
exposition of the EM spectrum to show how
much it has been dumbed down?

Grade 3? Why then say microwave radiation instead of light waves?
In any case, the real gloss went to theory of relativity and why there
should be any low bandwidth light waves. It is in the math of course.
Far beyond the reach of us lower types.

Really, why do we need separate names for
wifi
radio waves
microwaves

When they really are all different wave lengths of light? And cable
tv, cable internet are really light waves that pass through fiber
optic cables.

My suspicion is that different names for things adds some mystique and
suggests that something new has been invented. New technology,
innovation. Buzz words so the sales guys can make their pitch more
potent.

Besides needing to explain again, after the 3rd grade, that light has
all these various band widths, but is really the same thing, photons
traveling through space. And why a radio waves can travel through
buildings, but visible light cannot.

Willing to acknowledge my lack of the math skills to see why the math
requires microwave residue of the big bang. That does not make me
dominated.

Because "light" means "visible light" in
common parlance, and because that distinction
is important enough descriptively since one
uses a different type of telescope to observe
microwave radiation than one uses to observe
visible (or near-visible) radiation. It
helps tell the story.

Lower types = dumb ones. Check. Got it.

And BTW, it isn't "low bandwidth" waves. It's
low frequency (or long wavelength) waves.

Yes, like I said, dumbed down. The article was praising the
simplicity of the way physics describes things. Not so simple was my
response.

You don't need to be dumb to not groc higher math.

Right, don't know how that word slipped in there.

Hmm, all I said was that not everybody can dance in the meadows of
higher math. Not one word of domination or worship. That is all in
your mind.

It's so dumb calling something that doesn't light up, light waves.
Why doesn't anyone understand that?

It is dumb but factual. We are talking about how that article is not
a demonstration of why simplicity works. It could be a demonstration

after the big bang is not simple.

Calling things light that don't light up would be a complication that
gets in the way of dumbing down.
