Corrected entry: Naomi Doret, the woman who parachuted onto the island, is explaining about the outside world finding the wreckage of flight 815 "off the coast of Bali, in an ocean trench 4 miles deep". The problem with that statement is that Bali is nowhere near the Pacific Ocean, it's in the Indian Ocean. Oceanic flight 815 was a direct flight from Sydney, Australia to Los Angeles, US. That flight wouldn't go anywhere near the Indian Ocean or Bali.
Corrected entry: The numbers that appear everywhere in the show actually originated on a completely different TV show. Veronica Mars. A show about a teenage detective juggling school, boyfriends, and her father's investigation practice, where she helps out. In one of the episodes, Veronica takes a fortune cookie's fortune and puts it against her vanity mirror with the numbers showing - 4 8 15 16 23 42.
Corrected entry: Just after Hurley throws away his stash and everyone comes to get the food from the jungle (balloon), you see the faces of the people running. There is one man slightly to the side running to the food. This is Boone. He is already dead in the first season after getting shot. (00:03:05)
Corrected entry: When Sawyer was playing the tape to the group showing where Juliet was still working for the others; she and Jack walked up and she told them to turn the tape over and play it. On the other side it had her instructions and what they were planning to do in the next two days. She said she told Jack what the others were forcing her to do and what they had planed and when. However, earlier Richard was asking Ben if he wanted him to deliver the tape with the new instructions for Juliet and Ben was telling him he already did the instructions and was fixing to ask Tom where it was when Locke interrupted him by walking into camp carrying his dead father. Plus there was no recorder there for Ben to tape instructions and even if he did, there was no way Juliet could have known what was on the opposite side of the tape for Locke had took it and gave it to Sawyer.
Corrected entry: In Charlie's flashbacks aboard the aeroplane, we see he goes into first class to snort the heroin. As the turbulence hits, he leaves and nearly gets hit by the trolley, before buckling himself in - still in first class. Therefore when the plane goes down, Charlie should've been in the first class section of the plane and consequently shouldn't be alive and on the beach with the rest of the survivors.
Corrected entry: Ethan is inserting a needle into Claire's abdomen, a needle that large inserted into the amniotic sac at that late in a pregnancy would rupture the sac and the baby would have to be delivered. We know that Claire didn't deliver for 2 weeks after she was returned to the beach.
Corrected entry: Factual errors: when we see the statue of the Egyptian statue, it is incorrectly depicted on several levels. First, Taweret was never shown as a human with an animal head, like the gods Anubis, Thoth, Horus, etc., were. She was always carved as an upright, unclothed pregnant hippopotamus. Second, even using artistic license because this is a fictional show, someone should have done some research and realize that Taweret is a goddess and as such, she would not be wearing a kilt because that was only for male gods. Also, no god or goddess would be wearing footwear of any kind but if you look close, you can see that the statue is wearing something that look like Greek or Roman sandals. The only thing that the makers of the show got right is that Taweret is carrying ankhs.
Corrected entry: Towards the end of season five, they talk about how they need to get the nuke to destroy the energy at the swan. However, according to Newton's conservation of energy, energy can neither be created nor destroyed. So blowing up this pocket of energy with a bomb is futile, as it just wouldn't work. However, this is a major plot device, and Farraday, who is a very 'intelligent' physicist, is the one to come up with this pointless idea.
Corrected entry: When Ana Lucia kicks Sayid out of the room where they are holding "Henry Gale" she shuts the door behind Sayid. The door is a light brown color wooden door. Later, when Ana Lucia lets Lock in and shuts the door behind him, the inside of the door is metal. (00:13:25 - 00:37:55)
Corrected entry: Desmond claims that he was saving Charlie's life by saving Claire from drowning by jumping in before he does. However, if Desmond had not had a flash to witness the event of him dying, Charlie wouldn't have known it was happening either as he followed Desmond to the event. As we find out later, they were a mile inland, so there's no way Charlie could have found out until a long time after Claire had drowned.
Corrected entry: In the London pub, Desmond refers to the barman as the "bartender", a word never used in England. He also gets a drink without paying, leaving money on the bar when he leaves - this may be the American way, but in British pubs you always pay when you receive your drink.
