/sci/ - Science & Math

The cargo modules, C5 and C6, were dark and cold, deck upon deck of color-coded storage lockers and shipping containers. He found the crew rations on Deck C5A; sliding open one of the refrigerated lockers, he took a few minutes to inspect its contents: vacuum-sealed plastic bags containing freeze-dried substances identified only by cryptic labels. None of it looked very appetizing; the dark-brown slab within the bag he pulled out at random could have been anything from processed beef to chocolate cake. He wasn’t hungry yet, so he shoved it back in and slammed the locker shut.

Gillis returned to the ring corridor and walked to the hatch leading to the hub access shaft. As he opened the hatch, though, he hesitated before grasping the top rung of the shaft’s recessed ladder. He had climbed down the shaft once before already, yet he had been so determined to reach the command deck that he had failed to recognize it for what it was, a narrow well almost a hundred feet deep. While the Alabama was moored at Highgate and in zero-gee, everyone aboard had treated it as a tunnel, yet now what had once been horizontal was now vertical.

He looked down. Far below, five levels beneath him, lay the hard metal floor of Deck H5. If his hands ever slipped on the ladder, if his feet failed to rest safely upon one of its rungs, then he could fall all the way to the bottom. He would have to be careful every time he climbed the shaft, for if he ever had an accident. . . .

The trick was never looking down. He purposely watched his hands as he made his way down the ladder.

I'm not sure if this is /sci/ related, since it's actually not about theism or lack thereof.
Anyway, I'm an aspiring science fiction writer. And I can hear the protests already, but one of my ideas revolves around life in space. Now, I don't claim to know much about biology or astronomy because I'm a layperson. I know my place in these matters.
I just come to ask a few questions about my fictional "bioverse." Would any of you be interested in discussion?
