star trek - How can Delta Vega be so close to Vulcan?


In the new alternate timeline Star Trek movie, the icy M class planet Delta Vega is so close to Vulcan that the latter planet has an angular diameter that is comparable to Earth's moon when seen from the former. It is in fact close enough for an escape pod to reach it from the vicinity of Vulcan.


The Question:


In this case, should not Vulcan's catalogue name be Gamma Vega? Would this make Vulcan the third planet orbiting the star Vega? This star is 25 light years from Earth. Yet the Vulcan system is said to be 16 light years from Earth, which is widely believed to be the same as the real star system 40 Eridani A (though never canonically confirmed).


Also, why is a habitable planet so close to Vulcan not heavily colonized by Vulcans?




Answer



There's not a lot of in-universe information, although Memory-Alpha does say (without citation) that "Its orbit carried it near enough to Vulcan that the other planet could be seen from Delta Vega's surface." Perhaps Delta Vega had a very eccentric orbit. Although that's purely speculation, and it wouldn't explain Vulcan being in orbit around Vega.


From a real-world perspective, Roberto Orci talked about naming the planet after one from the TOS episode "Where No Man Has Gone Before":



"We moved the planet to suit our purposes. The familiarity of the name seemed more important as an Easter egg, than a new name with no importance."



And he also touched on motivation behind the scene in question in an online Q&A thread (comment 464):



"I prefer to think of Delta Vega as being in close orbit (although it could be a moon), but nonetheless, we like to think of that sequence as impressionistic for a general audience. In other words, Nero could’ve beamed Spock prime down to Delta Vega with a telescope or some other type of measuring device to allow Spock to experience the pain of perceiving the destruction of his home world, but that simply isn’t very cinematic."




So unfortunately, you probably just have to chalk it down to "poetic license".

futurama - How much time is lost in 'Time Keeps on Slippin''

In time Keeps on Slippin' , Farnsworth creates a basketball team which he matures by abusing Chronitons. This leads to time skipping forward by random, but ever increasing amounts. How much time was skipped in this way? Answer Unfortunately, I don't think a good estimate can be made for this, for two reasons: Many of the time skips move forward by an indeterminate amount of time. At one point, the Professor mentions localized regions of space skipping forward much more than others. We then see two young boys on the street below complaining about having to pay social security, only to suddenly become senior citizens and start complaining about wanting their money. Thus, each individual could have experienced a different amount of time skippage.

aliens - Interstellar Zoo story

I vaguely remember this story from my childhood: it was about an interstellar zoo that came to Earth with lots of bizarre and unusual species, and humans would file through and gape at all the crazy looking creatures from other planets. The twist came at the end when the perspective shifted to the other side of the bars and we discovered that the "creatures" were traveling through space on a kind of safari. They thought they were the visitors and we were the animals. Neither side knew that the other side thought they were the zoo creatures. Answer Got it. Zoo, by Edward D. Hoch. Published in 1958.

harry potter - What is the difference between Diffindo and Sectumsempra?

In the Harry Potter books, Diffindo is called the 'Severing Charm' and it’s most commonly used to cut ropes and the like. However, in the last book Hermione uses it on Ron but misses, creating a 'slash in his jeans' and his knee gets cut, causing him to 'roar in pain'. We've only seen Sectumsempra used once on screen when Harry directly uses it on Malfoy in the sixth book, but there it's mentioned that he is 'waving his wand wildly'. Wouldn't Diffindo, if used in such a fashion also cause a similar effect? Similarly, if it was able to cut Ron, it would also be able to, say, chop off an ear (George's)? In that case, how are these two spells different, except for Sectumsempra seemingly used exclusively to hurt humans? Answer While Diffindo and Sectumsempra both can be countered by other spells, Diffindo is far more easily countered. Reparo, a relatively common spell, can completely reverse its effect when used once. “He pulled the old cop...

harry potter - How could Expelliarmus beat Avada Kedavra?

I want to be very careful about how I ask this question – I am not asking How did Voldemort die? [CLOSED] Below the text is the relevant passages from Harry Potter and the Deathly Hallows if anyone wants to review them (I'm sorry for the amount of text). How did Expelliarmus beat Avada Kedavra and kill Voldemort? I feel the reason Harry's Expelliarmus overpowered Voldemort's Avada Kedavra curse has to do with who was master of the Elder Wand and how the Elder Wand works. I've always had trouble understanding fully how the Elder Wand works, though. How much did the fact that Voldemort never truly won or mastered the Elder Wand factor into how Expelliarmus reacted to Avada Kedavra and caused Avada Kedavra to rebound and kill Voldemort? An answer based in book canon would be especially welcome, but any canon source really is fine. Harry heard the high voice shriek as he, too, yelled his best hope to the heavens, pointing Draco’s wand: ‘ Avada Kedavra !’ ‘ Expelliarmus !...
