Can someone explain why Ford can't move the jumper from inside?
I understand newton's 3rd law but if you're sitting on a chair you can move it with some momentum without touching anything else.
When he pushes on the Jumper, it pushes back. He transfers that force back into the Jumper through the floor/air. The equal but opposite reaction has to leave the Jumper to achieve thrust.
I could be wrong though.
"BRITTA? WHAT KIND OF LAME NAME IS THAT?"
I thought the same but it confuses me that you can move chairs or your bed this way.

Chairs and/or your bed isn't generally half disintegrated in an open wormhole. They lost their momentum of moving when they got stuck.
Or better yet... you try moving your chair and/or bed through an opening that is just one bit too tight, it won't work either (even without the disintegration). No matter how hard you push or bump against the object. The reaction will come right back at you being bumped back.
I think momentum would also be a factor. The jumper will resist the change in motion because of its size and there was no way Ford would push it hard enough to get it through the gate. It's like trying to move a car by drop kicking its grill.
..or trying to get out of a swamp by pulling your own hair
I think (but I could be wrong) that you need an external hinge for the role of the fix point. When you move the chair, it's the floor. When you move a swing, it's the rope junction.
Looking at the blurb for the ep, I wasn't looking forward to watching this; switching between SG-1 and SGA episodes is time-consuming and means I can't rush right into the next episode in a series, after all . I assumed that pretty much the whole episode would take place in the jumper and would be pretty boring, but I'm so glad that it was more entertaining than I thought it would be.
Kavanaugh, though. Oh, god. I've seen people mention that there's some weird chemistry or sexual tension between him and Elizabeth, and just having the thought makes me want brain bleach. Just no.

Kavanaugh -- oh, we remember him fondly. He was such a "lovable" character.
I paired him once with McKay for a ficathon. Was a pinch hit, but everyone deserves a story written for them in these things so I volunteered.
Was it a slasher fic?
In the discussion about why Ford couldn't move the jumper, the post about getting stuck in the doorway with a chair--why omit friction? You can overcome the friction of the chair against the carpet with the momentum from rocking, but you can't overcome the additional friction of the doorway.
So maybe you could move a jumper a little bit through internal momentum, but you can't overcome the friction of the engine pods against the gate.

Just re-watched this episode. Nice touch using an old scientific discovery about the Stargate (wormhole closing after 38 minutes) and tying it into the main plot of the episode while the expedition still being able to learn something more of their enemy. Also, nice usage of recurring and guest characters. I just wish there were more episodes like this, where everyone is making effort to solve the team's problems in the Puddle Jumper.
Just re watched this, and I forgot that at the beginning Mackay pulls Ford out of the Event Horizon by his hand that was not in all the way. I thought once you started into the worm hole you were de-materialized and ONLY re-materialized on the other side?
Weir could have kept her mouth shut till later true, but I think she felt like she needed to assert her authority in the situation. Being in a position of authority and having those under you act like Cavanaugh did would annoy most leaders silly.
Then his little temper tantrum later about "you treated me badly", I think Weir was spot on in correcting him then for sure. It did set up the antipathy Cavanaugh would have for the chain of command from then on.
All in all good character building.
P.S. Cavanaugh with his "blow the rear hatch idea" saved the day!
Did I mention good character building?

Ford is an extreme example of this, but it happens with people "testing the waters" by putting a hand in and then pulling it nervously out. O'neill has also intentionally put a hand into a wormhole before to keep the gate active and then pulled his hand out ("Shades of Grey" - Season 3, Episode 18). In that case it was an incoming wormhole, though.
