Molecular Cloud Barnard 163
Breathing a bit heavily, Barnard turned the last page of Venus by the Lake. “Excellent” he thought, “That was even better than Aurora Over Alaska”. Bodice-rippers were a guilty pleasure of his, and once he got wrapped up in a book, he lost all track of time. But his current mission was mind-numbingly tedious-- mapping the minor black holes of the Cone Nebula Neighborhood. While large black holes could be detected by changes in the trajectories of nearby stars, small black holes could only be found by sending out sprays of tiny probes, at obsessively frequent intervals. He had travelled up and down this sector, following his assignment to the letter, and had found nothing. Barnard glanced at his control panel (all indicators at zero, as they had been for the last month) then stared moodily out into the emptiness of space. “Are we there yet?” he muttered aloud. In the back of his mind he knew he would be breaking contract by skipping even one data collection site. But, come on. This was rediculous. The Arms of NGC 4258 were beckoning…
Barnard settled into his seat, with a fresh-brewed pot of Earl Gray tea and his favorite porcelain cup and saucer nearby. Even in space, especially in space, one must have one’s luxuries. He sighed contentedly…Every chapter or so he paused to make a quick survey of the control panel, snorting irritably when it prompted him to initiate the assigned probe sequences. No one would know if he skipped a few.
In the middle of chapter 9 Barnard realized that his Gravitation Differential Indicator was beeping plaintively. “Oh shit” he said, and then made a decision he would regret for the rest of his life. Before he marked his place in the book, he took a few seconds to skip to the end of the chapter. Yes, his heroine would indeed survive the dreaded Bullet Pillars in Orion…
When he finally turned to the instrument panel he found a chaos of blinking lights and maxed out indicators. “Oh SH*T” he said again. For the next few minutes Barnard struggled frantically with the controls. His hands began to tremble and he found it increasingly difficult to remember the emergency procedures. Part of his mind split off to recall a lecture he had heard during his student days-- a lecture by the brilliant Neil Degrasse Tyson-- not the original of course, but his umpty-umpth clone. He could recall the words with an eerie clarity:
"The gravity at your feet, if they’re close to the black hole, is a little bit stronger than the gravity at your head, and you feel that as something that is tearing you apart. Stretching you from head to toe. The tidal forces unrelentingly getting stronger, as they exceed the molecular forces that bind your flesh…as you snap into two pieces and those two pieces snap into another two pieces…And so you end up moving through space-time like toothpaste through a tube. And if I were to pick a way to go, that’s how I’d want to go. "
As Barnard began to feel an odd sensation in his lower legs, he considered that in spite of the brilliance of Degrasse Tyson, in this particular instance he disagreed with him.
Several weeks later, Neil Degrasse Tyson 137 looked out over a crowded classroom, and in a mellow voice enhanced by centuries of experience, intoned " Matter falling into a black hole is a lot of stuff trying to get into a very small place. And so it is like trying to fill a dog dish with a fire hose; most isn’t going to get in. The black hole chokes on the influx, and the high speed whirlpool of matter produces a powerful magnetic field, coiling around the black hole and shooting the energy outward.
These enormous jets of energy, hundreds of millions of times the power of the sun, can blast right out of the galaxy.
And this, kids, …is the story behind Molecular Cloud Barnard 163."
