By now, Nick could visualize where he was with quite a lot of confidence.
In his mind, he saw a big wall with many holes, like a filter.
At some point, the holes would essentially split in two, but those splits were not equal.
One of the ways was much smaller than the other and was near the side, not directly in front.
It was like a big street with a small offshoot.
Anything that couldn't move without the help of gravity, air resistance, or friction would helplessly move down the big hallway into a dead end designed to catch these intruders.
Anything that could move like this would also travel to this dead end since the real path forward was so small and almost imperceivable.
'It's very clear that this is not an entrance but an exit. Nothing is supposed to get in here,' Nick thought.
