The Epistle oF light.
The Orion Nebula contains a very young open cluster, known as the Trapezium due to the asterism of its primary four stars. Two of these can be resolved into their component binary systems on nights with good seeing, giving a total of six stars.
The basic framework for the moving target that is flight comprises an architecture of anchors and change: weights dictate speeds which prescribe duration and altitude. The wooden stake in the ground, sure as the tenuous GPS alignment reluctantly tolerating the gusty wind bucking the 40 foot tall rudder assembly, will be ancient history as soon as we move. But to know where we’re going, we have to know where we started from.
The stars of the Trapezium, along with many other stars, are still in their early years. The Trapezium may be a component of the much larger Orion Nebula Cluster, an association of about 2,000 stars within a diameter of 20 light years. Two million years ago this cluster may have been the home of the runaway stars AE Aurigae, 53 Arietis, and Mu Columbae, which are currently moving away from the nebula at velocities greater than 100 km/s.
And drawn as moths to the flame, pairs and singles, Noah’s children march aboard, halfway to somewhere, their presence now a light reflected forward, as meaningless in the here-and-now as the two-by-two was in the pouring rain, boarding the ark: it’s all about the retelling later.
A nebula is an interstellar cloud in outer space that is made up of dust, hydrogen and helium gas, and plasma. It is formed when portions of the interstellar medium collapse and clump together due to the gravitational attraction of the particles that comprise them. The gravitational forces between particles is directly proportional to the their masses, remember?
“Now” is a moving target, mortgaged by “then,” which in the preflight cockpit is more about “there:” the air nautical miles divided by pounds of fuel burned per each. The symphony of electrons conjures an opus of transformation: if everyone plays his part, there will be a smooth harmony of fire, speed and distance, underscored by dollars transferred and spent, buoying steel and fuel, blood and bone, suspended across the night sky like the fiery tail of a comet from here to there.
When a star burns through the last of its fuel, it may find itself collapsing. For smaller stars, up to about three times the sun’s mass, the new core will be a neutron star or a white dwarf. But when a larger star collapses, it continues to fall in on itself to create a stellar black hole.
It’s always the “after” from which meaning is made. For the ark, that’s arrival. For the pilots, that’s enroute, the record inscribed across the night sky, 500 degree exhaust gas boiling away at -55 C ice crystaline air, backlit by the moonlight as a spider web across the star-flung dome. Keep the fires burning.
Black holes formed by the collapse of individual stars are (relatively) small, but incredibly dense. Such an object packs three times or more the mass of the sun into a city-sized range. This leads to a crazy amount of gravitational force pulling on objects around it. Black holes consume the dust and gas from the galaxy around them, growing in size.
And for those left behind, like those yet ahead, the unseen passage is one of either anticipation or regret, of bidding welcome or goodbye, of time spent or lost. You can’t not feel the diminishing weight of both, lighter the farther and higher you go. No hands hold you, just wings and lift, time and tide, fire and ice in balance. Passage.
Orion’s light is either a promise given or a wish fulfilled, depending on where you see it and when. At light speed, the trapezoid assigned to the mythology, the murky nebulae burning within, left home in the time of Alexander the Great, overtaking you at 41,000 feet a couple millennium later. Either way it’s a lie–a now from then, seen light years away; then as if now.
Just like your flight: you’ve crammed a million footsteps into the counting of minutes rather than lifetimes, footless, seven miles high, an ark sailing on a rolling tide of time and place, borne of fire, trust, hope, and light.
For those in the back, the metal ark is but conveyance. For you, more an arc inscribed across the night, more than passage but less than permanence. Like the silent, obedient constellation, the gas blue light won’t matter until it’s examined in retrospect. You live in the passage, grant the flight its own universal time and space, its million shards of where and when and ultimately, why. But it’s never about “there,” for you. Only leaving there, and flight across darkness: night, the shadow of life, then home, the nexus oF light.
