How does artificial gravity on the Ascension work?

Within the generation ship Ascension, there appears to be normal Earth-like gravity. Yes, I know about the twist from the end of episode 1x02,

that they are not really in space.

Nonetheless, there must be some explanation from the point of view of the people on board the ship (some of which even seem to be scientifically minded).

My impression was that it's generated through constant acceleration along the direction of flight. This seems to match up with the visuals, in that decks are stacked along the length of the ship, so "down" as seen by the crew points to the aft of the ship in the direction of flight.

This would require a constant acceleration of 1G (or at least something sufficiently close to it), which brings some mathematical problems.

On the other hand, this answer swiftly assumes that the acceleration of the vessel might be a lot lower than 1G:

Of course, we could use a lower rate of acceleration. For making a 100 years journey to Alpha Centauri, the slowest rate you can have would be to continuously accelerate at 0.00175g

This might point to some alternative means of creating the artificial gravity aboard the ship that I did not consider.

Thus, is gravity indeed supposed to be generated by acceleration, or is there some other source?

To the downvoter: Note that I am not asking for an explanation of a fictitious future technology here. The series this refers to is, by its premise, based on today's technology (or rather, even upon that of the 1960s). Given that it is, in a way, a part of the very premise of the series that there are no "obvious plot-holes" in the setting, one can expect that this feature of the ship is supposed to make sense either based upon some existing concept, or hand-waved in-universe towards the protagonists at some point.

languages - Do we ever see written English in the Star Wars films?

In Empire Strikes Back , we see a transcription of what R2's beeps and bloops mean, but it's not English (sorry for the low quality, it's from the 2004 DVDs): I'd assume it's what Basic looks like when written, but is there some point in the the Star Wars films we see written English instead? (This sort of spun off from a discussion in How do people understand astromech droids? .) Answer At one point there was English but it has been phased out in subsequent versions of the films. Chris Gould at DVD Active did a comparison of all versions of each of the Star Wars films, and in his comparison of Episode 4 , there are a couple of screenshots showing how the power gauge for the Death Star tractor beam was changed. I imagine there are probably more to be found in his other comparisons but I haven't got around to reading those yet.

Was the "pure soul" of Harry's what had really hurt Voldemort?

In the Order of the Phoenix, Voldemort possesses Harry, and it hurts. Greatly. I think that Dumbledore explained that it was because Voldemort's rotten soul was incapable of assimilating Harry's pure soul, that Voldemort didn't understand the love and friendship etc that Harry has in his heart. But, I think it was a lie. Remember that in Deathly Hallows, while looking for information regarding Horcruxes, it is discovered that it is in fact possible to merge a soul fragment back, but that the process was extremely painful. Now then, if Voldemort tried to possess Harry, and Harry had a fragment of Voldemort's soul, I think that it could have been the true cause of Voldemort's pain: the fact of having his soul so close of another fragment. I think that Dumbledore knew that fact, but had to lie to Harry because it was inappropriate to let him know that he had one of Voldemort's soul fragments at the moment. Is that right? Or was it truly the pure soul of Harry's...

star wars - What "exactly" happens when someone turns to the Dark Side?

When I saw the original Star Wars saga as a kid, the concept of the Dark Side imprinted in me was quite simple. You did a bad thing, so you're a bad person so you go to the Dark Side and keep doing bad things. Now, obviously this doesn't hold true in reality. In my mind it is perfectly reasonable for Luke to kill the Emperor and Vader and then just flee the Death Star and rejoin the Alliance. After all they are at war, those are enemy officers that have captured him and are taunting him by threatening with death of all loved ones and the whole operation was intended to kill the Emperor anyway. The same would hold true for Anakin. He could have killed Mace Windu to save the Chancellor and Padme but that doesn't mean he's going to then go mad and kill all Jedis including children. It doesn't add up from a merely psychological point of view. He had a set of objectives and that made him want to keep the Chancellor alive (quite valid by the way, Mace Windu is quite clums...

star trek - Warning regarding forward saucer section in Nemesis?

In Star Trek: Nemesis , just before the Enterprise rams into the Scimitar, Picard sends a text message from his captain's chair arm pad to Troi — who is manning the helm in lieu of the crewman who was just blown out through what was once the view screen — indicating that she should put full impulse on standby. (Literally, if you watch the scene closely, Troi's console prefaces the order with "TXT MSG" !) My question is: Did Picard also somehow warn crew members in the forward saucer section about what was about to happen? The ramming of the Scimitar was a heat of the moment decision. Considering that he also resorted to calling the auto-destruct sequence shortly after (which ended up being offline), he probably was of the mindset that any losses would be acceptable in order to hault Shinzon's march to Earth. Still, I'm curious. Answer The original script indicates that he called for the crew to " brace for impact ". Whether that call (or the comma...
