What Did Helen Do?
Or A Jumble of Space-Time Discontinuities.

_________________________
An alternate Universe branched off of the original. Our apologies for the
inconvenience. We had originally intended to devote today's article to the
recent Jupiter impact. That event will be the focus of Thursday's
DA...unless another branch off occurs.
Now, in this new reality, we return to Helen of Troy. Yes, we did hear that
exasperated sigh followed by the despairing lament, "Mythology again?!"
Please bear with us, Ursa Major.
__________________________


*What did the real Helen do?* That was the intriguing question a few
subscribers asked us yesterday. If you missed yesterday's article, we
mentioned that the mythological Helen of Troy, the one whose face launched
a thousand ships and burned the topless towers of Ilium, was abducted by
Paris and spirited away to Troy. Her abduction precipitated the famous
Trojan War. However, Hera, who hated Paris with an unslakable passion for
having awarded the golden apple to Aphrodite, was said to have stolen Helen
and replaced her with a cloud that looked, felt, and even sounded like the
original. Paris actually kidnapped this cloud. The entire 10-year skirmish
was therefore fought over a fog-based doppleganger instead of the "real"
Helen. She was said to have remained safely in Egypt while the Greeks and
Trojans fought valiantly -and vainly- over her.

Well, some readers asked, "What did she do while she was in Egypt? What did
she do after the Trojan War?"

Second question first. Well, while the Greeks were joyfully sacking Troy,
Menelaus was reunited with Helen who, on their first evening together,
promptly dissolved at, by all accounts, a particularly tender moment. (And,
yes, we are going to avoid the details.) The chagrined Menalaus then
complained to Hera, the goddess of marriage. His annoyance was
understandable. Nothing ruins intimacy more than realizing that you've just
bestowed lavish affection on a cloud bank. Hera instructed Menelaus to
travel to Egypt to collect his wife. He was also told not to mention the
deception to the other Greeks. (Menelaus was wise enough to have taken THAT
secret to his grave.) Helen then returned to Sparta with Menelaus on her
own accord. She and Menelaus conceived two children, Hermione (no, not that
Hermione) and Niccostratus. After Menelaus' death, Helen was said to have
traveled to Rhodes where the queen Polyxo, bitterly envious of Helen's
lasting beauty, had her hanged.

As for what she did in Egypt.
Who knows?
We have scant knowledge of what transpired in Helen's life during her stay
in Egypt because, well, unlike the physical Universe we inhabit, the
mythological Universe is riddled with space-time discontinuities. It is a
patchwork montage of sagas, poems, legends, and epics. As brilliant as many
of these accounts were, they were far less than comprehensive. They had
gaps, some as wide as a yawning maw. After all, Homer's masterwork, the
Iliad, focused primarily on the last fifty days of the Trojan War.
Apollodorus covers the entire Trojan war, but did so in an almost cursory
fashion.

One finds these space-time holes through not only mythology, but throughout
literature. Who knows what Hamlet ate for breakfast three days before his
father died? How did Scrooge react when Bob Cratchit asked for New Year's
day off, too? If the ancient mythological poets, the true gods who created
the mythological Universe, didn't write about a certain time or event, that
time or event will remain forever non-existent.

Our Universe isn't like that.
At least on the macroscopic level, these discontinuities don't exist. For
instance, something is happening at Mount Everest's summit at the moment,
even though nobody is present to witness whatever is transpiring. That is
true of the moon's far side, the Sun's interior and the ice-coated renegade
planets currently careening through intergalactic space. For instance, who
knows what happens in this star dome when nobody is inside it? Perhaps in
the middle of some quiet night years ago, a holographic iridescent
icosahedron released long ago by the hyper-mathematicans of Beta Pavonis
glided through the dome, down through the floor and then through the planet
en route to deep space. Perfectly possible, but never knowable. (Here we
will cheerfully ignore the philosophers who wonder if the unobserved truly
exists. Philosophers are brainy types who delight in making difficulties.)

When we interact with the mythological, we must acknowledge its surfeit of
space-time discontinuities. '

If nothing else, consider this article to be the longest, most insufferable
"I don't know" ever to be found outside the halls of Congress.

Tomorrow, equinox talk....we think.
