They have these "levitation-like" shots in a zero gravity space ship.

At first I thought maybe a wire harness or they did this with a chroma key/green screen
Then I believe the closeup shots around 3:01 gave it away. Pause at 3:01 and it looks like she's laying on a glass layer that for the most part looks invisible but here you can see small scratches on the glass. Also how her hair appears to be laying on top of something instead of floating in some of the closeup shots.
Anyone know what the name of this "invisible glass" is or is it just regular glass that they hid with lighting and post?
