In Interstellar, how could you build a space colony without bringing the Blight with you?


In Interstellar, there is a Blight destroying all the world's crops. If Plan A involves launching a space colony, presumably full of crops, etc., how could they avoid bringing the Blight with them?



At the end of the film we see that they've actually created space colonies. How did they manage to launch and populate them without bringing the Blight with them?




Answer



Common agriculture


Many current diseases of wheat and other crops are mitigated by chemical treatment of the seed grains - you can do pretty harsh things to them that will kill many different kinds of bacteria but still leave a seed that will germinate. It doesn't make them immune, but it allows you to re-plant them in a new disease-free location.


This is pure speculation, but if similar things are done right now, then a similar procedure could be developed to "cleanse" seeds of Blight.


Quarantine



Another common option is to identify some spots that aren't yet reached by the disease and use them to gather clean seed stock before it's too late. If really all (100% not, say, 99.9%) the world's crops are destroyed, then it still leaves seeds that are stored securely in the few isolated 'seed banks' that we have. Again, they won't be immune and need to be planted in a safe location, but even if you have a very small number of seeds (say, a dozen grains) then you can reproduce them in large quantities if you have a need and resources to do it.

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.

What is Tolkien trying to say in this letter?

In a draft of a letter, later recorded as #246, Tolkien makes a strange statement. I am interested in the first few sentences of the letter, but I will include the remainder for the sake of context. In the 'Mirror of Galadriel', 1381, it appears that Galadriel conceived of herself as capable of wielding the Ring and supplanting the Dark Lord. If so, so also were the other guardians of the Three, especially Elrond . But this is another matter. It was part of the essential deceit of the Ring to fill minds with imaginations of supreme power . But this the Great had well considered and had rejected, as is seen in Elrond's words at the Council. Galadriel's rejection of the temptation was founded upon previous thought and resolve. In any case Elrond or Galadriel would have proceeded in the policy now adopted by Sauron: they would have built up an empire with great and absolutely subservient generals and armies and engines of war, until they could challenge Sauron and destroy ...

tolkiens legendarium - Was Galadriel's temptation of Boromir instrumental to his fall?

We know Galadriel tempted the members of the Fellowship, did she tempt Boromir with visions of taking the Ring and saving Gondor? In the books, Boromir willingly accepts the judgement of the council that the Ring should be destroyed, but after the meeting with Celeborn and Galadriel his personality seems to change. Was the temptation offered by Galadriel in some way responsible for Boromir's fall? Answer It's likely, but not certain I believe it is likely Galadriel tempted him with the ring, and in doing so re-ignited a pre-existing idea to take the ring, but to be clear lets break this down into three parts. Boromir at the Council of Elrond Boromir after setting off Boromir after being tempted Boromir at the Council of Elrond Boromir pleas for the ring to go to Minas Tirith, to help Gondor in its defense against Mordor. “ Why should we not think that the Great Ring has come into our hands to serve us in the very hour of need? Wielding it the Free Lords of the Free may surely...

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...
