Corrected entry: After the Ancient device releases O'Neill and he collapses, Carter checks his pulse. She is kneeling to his left, yet reaches for the right side of his neck. Anyone trained in basic first aid and CPR (as Carter should be, with her field medic training) is taught that you always check the pulse on the same side of the body where you are sitting, so as not to risk compromising the person's airway by accidentally compressing the windpipe.
Corrected entry: When Jack is on the Asgard planet, there are a couple of shots of a red corridor/hall with a lot of Asgard standing around - this set is taken directly from the later levels of the Nintendo 64 video game 'Perfect Dark' with minor colour changes to the set.
Correction: This can't be, because this episode was originally shown in 1998 and Perfect Dark wasn't released until 2000.
Touchstone - S2-E14
Corrected entry: When SG-1 retrieved the Touchstone in Nevada after the thieves escaped through the second gate, why did they not just take the Touchstone back to Medrona using the second gate? Considering the world was on the verge of destruction, they thought they would have the time to fly back to Colarado and use the gate at stargate command. The NID guys escaped through the second gate right before SG1 got the Touchstone. And there was a DHD connected as well, so all they had to do was enter in the address on the DHD.
Correction: Because it would be suicide. Getting to Medrona would be fine, but when they got back they would find themselves a smear on the inside of the iris. They didn't have their GDOs, why would they, they are on Earth.
Corrected entry: When O'Neill throws the knife at the System Lord, the knife disappears and you can see the knife already in his hand before the sparks start. Best viewed in slo-mo.
Correction: This is only true if you have watched the version that is edited for violent content, for showing before 8pm. In the original version, you do actually see the knife being thrown into the hand device.
Touchstone - S2-E14
Corrected entry: In this episode, Hammond says that a permanent iris will be welded over the Beta gate. In Nemesis (Season 3), he says "I want the beta gate unpacked and ready for use as soon as humanly possible." What happened to the words 'Permanent Iris".
Correction: In this case, the words "as soon as humanly possible" can be reasonably assumed to mean 'as soon as you can cut the iris off'. It was designed not to open, not to be indestructible.
Corrected entry: Selmak tells Jacob Carter that the symbiote is for life. However, in the episode where Jack gets a Tok'ra (I believe it's called Abyss) they say the Tok'ra could enter, cure and leave.
Correction: The Tok'ra are constantly looking to increase their numbers and aren't in the business of healing people. The agreement was that Jacob Carter would be healed but he would have to join them as a permanent member. However, it's not like they can't make exceptions. Jack desperately need to be healed and the Tok'ra needed the information from the symbiote. Knowing that Jack would never agree to permanently bond with a symbiote they made an agreement that was appropriate to the situation.
The Serpent's Lair (3) - S2-E1
Corrected entry: Lt. Col. Samuels claims that the missiles they plan to launch against the Goa'uld ships are made of the same material as Stealth aircraft and should therefore be invisible to radar. The missiles however, unlike Stealth fighters, have jet engines which are visible to the naked eye, thus negating the Stealth technology.
Correction: The visibility of the propulsion does not negate the fact that the missiles are made of the same material as stealth aircraft and that they are invisible to RADAR. They are hoping that there are no Jaffa looking out of the Hatak windows.
Corrected entry: When a stargate first opens, we see what looks like a splash of water. In "Prisoners" we learn that this is an unstable wormhole being established between stargates, we also learn that anything in the way of the splash will be instantly disintegrated. How then is the Iris not disintegrated when the stargate opens while it is closed? Granted, the iris is slightly inside the event horizon, but if it would not be affected because of that, the splash should be seen coming past the iris. Neither of these things ever happens.
Correction: It is thought of that a wormhole can still be established even if the "splash" is prevented due to the iris as in episode "A Hundred Days" where the stargate is buried, they are still able to dial to it because an iris of sorts was formed (they explain this), they used a proton accelerator (or something) to create a space. Once the space is large enough they can then dial and the "splash" will encompass the whole cavern making it even larger. So for the splash to occur there just needs to be a volume large enough to encompass a minimum amount of the splash.
Corrected entry: The star collapsing into a black hole suddenly seems to increase its gravitational pull on the planet that SG-10 is on. When an object collapses to a Singularity, the pull it exerts on an object does not suddenly change because the mass, and therefore the strength of its gravity, has not changed.
Correction: The gravitational pull of the Singularity doesn't change. The SG team simply didn't know it was there, and its effect increased as the planet's rotation caused the black hole to "rise" in the sky. Just as the Sun doesn't get hotter or colder during the day, it still feels hotter at midday than at sunrise.
Your analogy is flawed because the sun's heat is blocked by the earth until it has a line-of-sight, while gravity's effect goes through the planet. A black hole millions of miles away would have no noticeable gravitational difference during the different phases of the planet's rotation - noon or midnight. The only way what you said would make any sense is if the black hole is small and close to the planet, but then that wouldn't be a black hole from the planet's star collapsing since the mass and distance would be wrong.
Correction: Black holes certainly increase gravitational pull and can tear planets apart. In additions, black holes are pulling in matter around it, adding to its mass.
A star and a black hole formed from it have the same mass and cause the same gravitational pull on objects outside the star's original diameter. Yes, a black hole pulls in matter around it, but that is the exact same matter that would also be pulled into a star of the same mass, so again the star and black hole would have the exact same effect on everything around it, including the planet. Regarding black holes (and stars) pulling planets apart, that is from tidal forces that grow exponentially as they approach a large mass, and again for objects at a distance outside the stars original diameter a star and black hole of the same mass cause exactly the same effect. The reality is when a star collapses into a black hole, some of the matter gets ejected and causes a supernova during the process, so the planet would have been torn apart long before any black hole was present, with the planet's debris thrown away from the event, not sucked towards it.
No, the gravity on surrounding objects does NOT increase, unless the black hole absorbs sufficient amounts of matter to increase it's gravity noticeable. Merely turning a star into a black hole won't affect objects such as orbiting planets.
Correction: I have had First Responder training, which is a step above Basic First Aid/CPR in the levels of EMT training, and there was never a mention of this. If you know what you're doing when you check for a carotid pulse, then you run no risk of compromising the patient's airway as the arteries you're supposed to be pressing on are well behind the trachea.
