Couldn't there be a better name for this? Sounds like it could be easily confused for a deception trope.
I have removed the 'reactionless drive' part from Firefly as according to http://firefly.wikia.com/wiki/Firefly-class_transport_ship
it has two engine types: Bussard ramjets on the nacelles and an "Enhanced graviton accelerator core" that powers the main "Firefly drive". The former is conventional reaction engine technology; the latter is a bit more murky but seems to suggest the same, particularly as gravity as known cannot violate conservation of linear momentum.
I deleted the second-level bullet added to the following entry:
- Robert Charles Wilson's short story "Divided by Infinity" takes the idea of quantum immortality (a legitimate — although not universally accepted — implication of quantum mechanics) and starts running with it. It is shifted toward the soft end by the otherdimensional books at Ziegler's bookshop, however.
- Nope. Actual science, if niche.
- Nope.
...because (a) as the comments of other scientists here indicates, it's pretty speculative, and (b) there's no real explanation given as to how the Mangled Worlds hypothesis would explain the otherdimensional books.
Alien 3 seems about as hard as the first two films (to me, anyway). Sure, the chestburster grows into an adult fast, but you could say the same about the Xenomorph in the first movie. Also, having elements of its host is explained as horizontal gene transfer, and the first two films also had Xenomorphs that had human-like features like bipedalism (so the Runner alien just follows the logic of the first two films).
