Threshold gas mine question

When Thel cuts the cable to the Threshold gas mine, the facility began falling at a fast rate. However, when Thel, Sesa, and Tatarus who were outside of the facility were not thrust away due to the enormous speed. How do you think that happend?

There’s probably some sort of field affecting gravity on the station. I mean Threshold is bigger than Jupiter, so it should have some pretty immense gravity, but everyone walks around on it like it’s earth.

Space-magic.

Yeah, antigravity seems logic.
