VIKI appears in the film I, Robot . [embedded content] ( warning, spoilers in the clip ) Does this character appear in any original writings from Isaac Asimov or was she purely a creation of the film?

The stealth mode of starships plays a huge role in many Star Trek films and episodes and is a strong advantage in combat. I remember an episode revealing that the Federation developed a secret stealth technology (afair on Riker's former ship with another captain appearing in this episode) that even made it possible to fly with the ship through matter. Nonetheless, while stealth technology seems standard for Romulans, Klingons (Ferengi, Vulcans?) and does not break any intergalactic laws (do these exist at all?), the Federation doesn't use it? Answer The Federation signed a treaty with the Romulans specifically forbidding the Federation and Starfleet (probably all life forms that are members of the UFP) to even research cloaking technology. They don't use it, because it keeps the peace truce with Romulus. From Memory Alpha : In 2311, with the signing of the Treaty of Algeron, the Federation explicitly agreed not to develop cloaking technology . The Bajoran Provisional G...

After Gandalf died from the injuries he sustained whilst fighting the Balrog , he was resurrected by Eru: Gandalf's body lay on the peak for nineteen days, until he was resurrected by Eru and sent back to Middle-earth alive In the Two Towers movie, we don't get much of an explanation: I've been sent back, until my task is done. [embedded content] In the books, do we get a better explanation of who sent Gandalf back and why? Is Eru mentioned specifically? Answer Here's what Gandalf says about his resurrection: "Then darkness took me, and I strayed out of thought and time, and I wandered far on roads that I will not tell. "Naked I was sent back - for a brief time, until my task is done. And naked I lay upon the mountain-top. [...] I was alone, forgotten, without escape upon the hard horn of the world. There I lay staring upward, while the stars wheeled over, and each day was as long as a life-age of the earth. Faint to my ears came the gathered rumour of all ...

First Age: Eärendil goes to Valinor and most of the Valar want him dead (correct me if I'm wrong) for daring to step foot on their soil. Second Age: Manwë strikes Númenor with Thunder and Lightning instead of sending emissaries, killing many men invoking Ar-Pharazôn to attack Valinor. Can anyone shed some light as to why the Valar acted this way toward them? Answer No. The Valar were looking out for Men as best they could, but they were hesitant to get very involved, because of the mortal nature of Men and their prior experience with Elves. Remember that Men very quickly fell from grace, as well, so they were in a 'state' more like the rebellious Noldor than they were, say, the Vanyar. To Hildórien there came no Vala to guide Men, or to summon them to dwell in Valinor; and Men have feared the Valar, rather than loved them, and have not understood the purposes of the Powers, being at variance with them, and at strife with the world. Ulmo nonetheless took thought for them, ...

After Arya saves Jaqen H'ghar and the other guards he was with, Jaqen promised her he would kill any three persons she named. Why didn't she name Tywin, who would was leading the war against the North, or Cersei and Joffrey, who were holding her sister captive? Answer In the books we get a clearer look into Arya's head. By the time Jaqen showed up, Arya had a amassed a long list of people she wants dead (her night time prayer in the TV show). Her first kill was an experimental spur of the moment thing (although the identity of the victim is different in the books). The second kill wasn't much better in terms of having deep thought behind it. Realizing this, Arya knew that she had to make the third kill count. Through a mixture of procrastination, not being able to make a decision, and being drunk on her power over life and death (her persona as the Ghost of Harrenhall) time slipped by and Tywin left. Knowing that sending Jaqen after Tywin (or other people not close by...

One theme of Harry Potter is that it deals with life's unpleasant realities. Harry's parents cannot come back to life and Harry will never meet them, this side of death. And there's no simple way to defeat Voldemort. Whatever happens, people are going to get hurt and others will die. There are consequences for one's actions and there is a price to be paid for one's gain. But this almost doesn't happen in the case of saving Buckbeakat the end of Prisoner of Azkaban . They use the time turner and break a few rules and basically avoid the law of cause and effect. Buckbeak's death, while unfair, was still a result of the choices made, and the results of those choices when nasty people can do what they want without checks and balances. Is there a price they pay for saving Buckbeak? Are there negative consequences, or did those involved manage to pull this off without facing negative consequences? Answer Had they not saved Buckbeak, Sirius would have (again) suf...

We know the zombies have a fairly simple existence, they can only perform basic functions (like walking) and only care for eating flesh. Yet in the Walking Dead series literally years are passing since the first outbreak and these zombies are still active. Wouldn't their brains eventually die due to low glucose levels or something? So even if the zombies are still active years later, why so many of them? We know there are other groups in the Walking Dead universe constantly killing lots of zombies every day, at a pretty good rate. Is this ever explained? Answer They do In Letter Hacks #14 and #111 it's stated Zombies eat for impulse and posess no functioning digestive system, with what they've eaten being forced out once its full, unprocessed. It's not required for their sustained animation. Robert Kirkman wrote on Reddit: ...In the beginning of the show we saw walkers do things like using a rock to help bash the doors in or turning a door knob, is there a reason we...
