The blood may not boil in a temperature/boiling sort of way, however your blood carries a lot of gasses in solution. When you drop the surrounding pressure the gasses come out of solution. Think of the CO2 coming out of solution when you open a soda that you shook up. Something very similar would happen to your blood as it quickly turns to foam.

Maybe Bones was just trying to describe it in a way that Kirk would understand?

There were no geniuses creating this movie, only hacks. Take the time travel question in post 203. Perfectly reasonable yet totally untouched by the movie. Why is this? Because time travel was used as a very simplistic vehicle to serve two purposes. #1 is to provide a scary monster, the big bad future ship with big mean spikes on it and punk romulans with bad attitudes. A very lazy bad guy out of the bad guys 101 movies book. #2 is to provide another lazy tool for the reboot. Instead of trying to fit into the original cannon which would take actual intelligence and skill just wave a magic wand and say “hey time travel, we don’t have to fit into an already established cannon”. Since they used time travel simply as a device to provide these two things they stopped there. They didn’t care to ask what kinds of other questions time travel of this nature creates.

There are so many things horribly wrong with this movie that it would take many more articles. It’s just so sad to see how many people actually enjoyed this mindless romp. This is why we are given movies like Transformers2 and GI Joe that have no intelligence at all to them. But then that was the point of this reboot, to make Star Trek likable to the new generation of young non-thinkers.

Nero returns 154 years in the past – why doesn’t he go back to Romulus and tell them about the supernova? They would have 154 years to think of a solution or to evacuate!
Narada would also give Romulans a huge technological advantage – probably enough to defeat the Federation…

I have a couple of things to add, though (I didn’t have time to read comments, sorry if there are duplicates):

Space jump
- why does the drill have spikes? Spikes would only make sense if the drill was physically drilling through the planet.
- why did they have to drill? Wouldn’t it be enough to just launch the “red matter” towards the planet?

Delta Vega
- what are the odds of Kirk’s pod dropping exactly on that in-the-middle-of-nowhere planet/moon and run right into Spock’s cave? It’s a classic “Casablanca” scene (”Of all the gin joints, in all the towns, in all the world, she walks into mine”) :)
- was Enterprise already on course to Earth? Did they make a detour to drop him off?
- a little off topic issue: the creature’s anatomy is extremely weird and not at all appropriate – I would expect some kind of space-penguin or a walrus, not a side-headed mantis…

Supernova
- just one thing – speed of light! The blast wave cannot possibly travel faster than light. Since Milky way is 100 000 ly across, even if the star was in the (geometrically) best location (center of the galaxy), it would still take at least 50 000 years for it to destroy the entire galaxy. If Romulus was orbiting that star, the destruction would be very swift (couple of minutes) and nobody could even realize it in time (unless they predicted the explosion – like noticing the star has expanded several times :))). Otherwise, it would take years (if not hundreds or thousands) for it to even reach Romulus, so it’s pretty hard to “be late”
p.s. in the “trying to save Romulus” scene, Spock is near the blast wave, and he can see it – therefore, it’s much slower than c – so, we’re talking tens or hundreds of years before it reaches the CLOSEST planetary system…Romulus could have been easily evacuated…

Titan
- another way to hide is just to be BEHIND the moon. The only way to detect them would be to search for some kind of EM reflection on the clouds of Saturn, and that sounds pretty improbable…Of course, emerging through Titan’s clouds is much more cool :D

Nero’s choice
- what happened with that black hole? Did it stay in the Solar System? I guess it would be a worse problem than Nero :D

Cheers!

If the hole is perfectly spherical, then theoretically there is equal pressure on all sides of the hole, which would prevent collapse. The material (rock or whatever) should hold up to it, since it was already under that kind of pressure before the whole was dug.

I assume the difference here is between a solid core and liquid core planet. On our planet there is uneven force on the hole due to plate shift forces and other gravitational forces such as the moon. If Vulcan doesn’t have either of these, i say a hole to the center is possible.

Though if there is no fluid core movement, whats to create the field that stops the solar wind?
