So, if you are still out to see it, set your shields for Jules Verne level physics if you want to enjoy it to the end.

Thanks, I'll keep that in mind once I get around to watching it.

On a random note.

Finally seen Star Trek: Into Darkness.
Great movie, but i had my suspense of disbelief set to ordinary Star Trek level, so near the end it got over overpowered and blew out, making me finish the movie in nitpicking mode.

Which blast took down your shields? I can think of a few bad ones in that movie, although I liked it in general...

The Enterprise was behind the Moon.
Engines cut out.
It starts falling...
To Earth.

From right next to and behind the Moon.
To Earth.

People inside were falling earthwards as the ship tumbled, just like in Jules Verne's Moon cannon projectile.

Within 10 minutes it was in the atmosphere.
From the Moon, on a free fall.

That's not just bad physics, it's cartoon physics. It's bad even by Star Trek standards.

Well, after than i just started nitpicking.
Like, why the big bad was throwing the good guy onto the bulk of the shuttle they are fighting on instead of tossing him off, why there were no radiation suits near the warp core, why copy the key line from the original movie instead of making it in character, why did that big character in the beginning died in a world where there are working cryonics and knowledge how to make regeneration blood, etc, etc.

But that's ok. After the puppeteer tumbled off the ceiling of the theater it's hard to keep keeping track of the puppets.

Same here, although I wondered if a spacecraft can have velocity inside of the warp bubble, but not move because space is moved around it? In other words, if you need to warp space around an object, wont it already have a velocity relative to the inertial reference frame that would have to be killed?

(ie, say the Enterprise is sitting in LEO. The warp drive starts up & it starts moving. Once it drops out of warp, doesnt it have 7600 m/s velocity in whatever direction was prograde when it created the bubble?)

But yeah, the falling to Earth one was pathetic. More than that I really disliked the poor use of "Cold Fusion" at the start of the movie. :thumbsdown:

Meh, it's Star Trek. Technobbabble phlebotium is expected there.

But when engines failed it was explicitly said that they got caught in the Earth's gravity field, not that they are still drifting towards it. If only that one line was 'engines are down, and we are still moving straight towards Earth', all the rest would have been quite tolerable.

@Artlav: Yeah - falling from moon in 10 mins was pretty bad on physics part, however it's Startrek so I can suspend my belief for a while. Lower than usual Startrek level but still movie was pretty nice to watch IMO

@BruceJohnJennerLawso: Depending how this bubble actually work.

I think (and this is speculation here as it's beyond my understanding of general relativity) that by manipulating spacetime you can easily cancel out ar adjust any movement of the ship in relation to your target. Looks like startrek does that way.

On the other hand in "The Night's Dawn Trilogy" by Peter F Hamilton they had to cancel out speed difference at target after jumping from one system to another. For that they used fussion engines (He3 powered).

*More advanced, sentient and partially biological ships were using their's "spacetime distortion cells" both for warp travel and movement inside solar system.

Generally agreed. This one was such a frustrating thing to see, pieces of intermixed with absolute gold. The scenes with the Jupiter shipyard were amazing for me.

Well yes, that was the whole point of going to warp, but you cant get rid of inertial velocity without going the conventional rocket route. On the other hand, you could stay in warp for as long as you need to burn the ion engines to get rid of the relative velocity, but that could take some time.

[Speculation] From my limited understanding of general relativity applying thrust while still surrounded by warped (expanded part) space should make great difference in dV. [/Speculation]

No offence intended, but I would really like to see how that works .

I haven't studied GR a great deal yet, but I should be able to converse a bit more intelligently soon. I did have a conversation with my Physics prof, where he indicated that he thinks the future of space travel lies with the Albucierre drive. In light of the holes in that idea Ive heard of since, I will need to ask him in a bit more detail about its validity.

You know what gravity losses are right? Taking general relativity into acount it's moving away from positivelly curved space to flat space.

In case of warping technology moving away from negatively curved space (expanded/bloated) would give you additional net thrust away from it. Gravity gains.

Huh :scratchhead:

I have heard of gravity losses, but to me understanding physics means being able to do all the calculations, so I cant claim to really understand it just yet.

But just to sanity check the idea, if additional kinetic energy is being gained/lost, where is that energy coming from?

 

[Urwumpe]

It is simply work done in the gravity field. When you move from a high gravity potential to a lower one, you gain energy (= you fall).

The Alcubierre drive now assumes that you simply have exotic matter with negative gravity.

But! Now the trick question: How much energy do you gain when you are not moving relative to the gravity field, like in the Alcubierre drive?

The fun really is: The spacecraft with the Alcubierre drive is not moving at all. Space moves for it and the spacecraft only needs a bit of velocity relative to space. When the Alcubierre drive is powered off, it would slow down to this initial speed again.

I liked the warp effect from the 2009 Star Trek...don't know why they added blue trails that are left behind once the ship goes into warp. Not really bad but...i need an explaination. :rofl:

Simple. Walter White had to escape ABQ after Hank told his friends at the DEA. So he used his meth money to buy a TARDIS from Henry Van Statten, then took Jesse to the year of the 'Trek movie, and hid away in the warp nacelles. Thus whenever the Enterprise warps, it blows all of his 'product' out the windows.


...duh

As I was playing Ace Combat 04, I noticed that the rocket being launched from the Comona Islands looked like the Ariane 5.

Oh wow, it does. I never thought twice about it.

Well, I'm all up-to-date on Attack on Titan now. Possibly one of the best series I've ever seen. Quite impressed.

Just realized how much is wrong with the built-in altitude autopilot.

Back in the day I used to play flight sims with the old Microsoft Sidewinder Force Feedback Pro (version 1 - gameport interface). Yes, I bought the stick. Why? I was a flight sim noob, eager to get the best, and I bought John King's cheesy Flight Simulator 2000 pitch hook, line, and sinker.
