Defying Gravity/Headscratchers

The Anti-Grav Phlebotinum
OK, so their suits have some magnetic nanite system that holds them to the floor. Fair enough. And their sleepwear must do something similar, despite not going below their knees. And, since giving them realistic crew-cuts would be unacceptable due to Rule of Sexy, they presumably use nano-conditioner to sort that out, as their hair hangs straight down even when they're floating around naked. As for why anything they're holding appears to weigh the same as it would on Earth until they let go of it... er, A Wizard Did It.
 * And it's just dawned on me how ironic this complaint is given the name of the show...
 * They explain it with nanite infused clothes using magnetic fields to simulate gravity, and they use this funny hairspray stuff for the hair.

FLT Communication?
How the hell are they still in real time communication to Earth? Even at the closest apex, surely there's a few seconds lag.
 * This Troper always figured on some sort of quantum entanglement-based communication system. Then again, he usually tries to defend show creators.
 * Entanglement doesn't transmit information from one place to another.
 * Could the lag just be edited out for pacing?
 * The creators specifically mentioned that they considered the crew sending messages to Earth and back, but decided it would mess up the pace they wanted. Although being able to send a signal from a spaceship to a cell phone is a little farfetched.
 * Fridge Brilliance: The method (whatever it is) is derived from the communication between Alpha and Beta as spotted by the radio astronomers on the show. The coversation there obviously lacked a time lag. So while the method is not explained, how it was discovered is.

Mars
So, Alpha doesn't like someone for an arbitrary reason and decides to kill them?
 * Based on the way Venus was handled, no. Alpha decided to push them and see if they'd risk staying in the storm. Thanks to Gos, the didn't which is why Alpha's still on Mars and people are dead.
