She must know the truth

I love that every Sci fi show eventually does the "out of phase" episode, and I love seeing the fun twists and flavorings they use to make it "their" version.
Like Stargate sg1 and their crystal skull radiation and advanced dimension-shifting technology episodes.
And my personal favorite lampshading for this is actually from Stargate. in the in-universe parody show "Wormhole X-treme" one of the main character parodies asks "if I'm out of phase, why don't I fall through the floor?" and the response from the writer/director/producer/whatever he was, was something along the lines of "I'll have to get back to you on that"
- Wormhole X-treme is the best. They criticize and second guess every plot-issue on the series.
  My favorite is on the last season:
  I'm writing the story for this episode, and the characters are stuck on $complex_situation$. I don't know how to get them out, do you have any idea?
  Why don't they $stuff_stagate_did_2_episodes_ago$?
  What? No! That's stupid! - and goes on for a minute or so enumerating all the problems with the plot.
  
  My favorite part is all the inside jokes they pack in as well. You don't really get all of them as a viewer, but I've watched every episode with commentary, and a lot of interviews with a lot of the directors, producers, prop/costume/sfx people.
  Nothing beats the "special effects coordinator" guy screaming BIGGER at everyone after they show him progressively larger explosive effects.

  Indeed.
- Lower Decks, per usual, had the best take on this trope.
  in the in-universe parody show “Wormhole X-treme”
  That whole episode was such a gift.
- In Batman Beyond, the out of phase person is a bad guy. He's using a machine to control his phase. Eventually he loses control of it and he really does fall through the floor. He's stuck in the center of the earth for the rest of the show.
- EXTREME WARNING if you have something important to do today. The above link is to TV Tropes. It's too late for me, but you still have a chance to be productive today!

Multiphasic structural integrity fields
- Gravity generators are on each floor!

I believe there was originally a line of dialogue about there being resistance when they pushed through objects, which was supposed to explain why they don't just fall. That line was cut, but IIRC it is still referenced indirectly when Geordi's hand gets zapped and he says that there was more resistance to pushing through stuff afterwards.
That wouldn't explain why there is enough resistance in the floor to stand and walk, but not enough resistance in walls to prevent them from easily passing through. Presumably their mass and the pull of gravity are unchanged, so the resistance would have to be enough to counteract their weight. And even if they did weigh less, they still propel themselves forward through walls by pushing off the floor, so either the floor needs to be more solid, or they should be nearly weightless and move by paddling their feet through the floor until they build up momentum enough to smash through a wall. Also, if they are applying pressure to objects they pass through, shouldn't people they touch feel it?
Personally, I'd probably explain the floors specifically being impassable by blaming it on the way the artificial gravity is generated.
I don't have a good explanation for how they can breathe, how they see without interacting with light, how they can hear clearly when matter isn't really touching them and therefore can't conduct sound, etc.
- I don't have a good explanation for how they can breathe, how they see without interacting with light, how they can hear clearly when matter isn't really touching them and therefore can't conduct sound, etc.
  That is obviously due to a phase shift in the quantum fields, which is correlated to the mass of the interacting matter (through the Higgs field). This leaves you interacting with light stuff like air and light, but prevents you from interacting with solid stuff like walls (and potentially force fields, if that would fit the episode).
  Of course, artificial gravity affects the mentioned phase shift by bending spacetime.
  And now I must go, before my handwaving creates enough energy to form a black hole.
  
  Your technobabble is on point, you should be in the writers' room!
  
  Then how come other people can't see them?

And how did they breathe?
- Ro died before ever learning the answer to that one...
  
  Jesus, they killed her too? How many interesting secondary characters did they off on that show?

I looked it up on Google, they couldn't "look down" and thus couldn't fall.
- This is the exact same reason dogs don't fly around. They can't look up.

Obviously, it has to do with basic operations of the main deflector dish polarising the outer hull and parts of the floors
- Now who can argue with that? I think we're all indebted to TheFerrango for clearly stating what needed to be said. I'm particulary glad that these lovely children were here today to hear that speech. Not only was it authentic Star Trek technobabble, it expressed a courage little seen in this day and age.

I like to think that they did... a few inches... till their shoes hit the spinny-ma-thing gravity generator below the deck.

Don't even ask the harder question of why they were able to stay inside the ship as it moved.
- Inertia dampeners.
- They were part of the ship's frame of reference. This applies to standard physics but is explicitly true if there's a warp bubble around the ship.

Question for the writers or Q, not Picard.

Another question: How you fall down in space?
