This is a pit nitpicky, but in one of the cinematics in the campaign, you see an arm floating in space with red blood oozing out of it (i think it's when Mengsk talks on TV). But shouldn't the blood be blue, because the arm is in space and deprived of oxygen, so the haemoglobin won't have any oxygen to react and change color? What do you think :P
shareYou're right, if it actually happened. The way it played out, I'm not sure if what we were watching was an edited together propaganda film made by Mengsk or depictions of actual events taking place at the same time as the speech.
I tend to lean towards it being a propaganda film, and that the hand was put in there for some sort of symbolic message. If that's true, the color of the blood wouldn't really matter.

Short answer: no, blood would still be red, and probably dark red at that.
I cant check that link, but I would imagine that blood would stay red until the oxygen was removed from it, by being run through the body. Blood doesnt "run out" by itself. When transfusion blood is stored in bags it stays red (though pretty dark) indefinately.
Its almost as though the oxygen (and therefore the redness) is trapped in the cells.
space is very cold, there would also be no oozing

No brilliant astrophysicist here, but my education in physics tells me that there are temperatures in space, so um, unless you can disprove that, you sound like you're clueless. In fact, Kelvin was used, if I recall correctly, primarily, if not exclusively, to deal in the temperatures found in space.

I'm surprised that no one mentions that the cigarette he/she/it's holding shouldn't be lit either.
Anyway, I think Blizzard just wanted to make a nice video.
Wich they did.

dude, it's a video game...
shareTruthfully, almost everyone is wrong.
Because there is no pressure in the veins and arteries of the floating arm, blood would not "ooze" the way it does in the video, only because there would be no internal motion and therefore nothing to push the blood out of the arm.
Also, blood doesn't turn blue when it is de-oxygenated, it turns a deep red. The blue color you see on your arm or leg or whatnot is due to the color of the vein and not of the blood flowing through it.
But, temperature can exist in a vacuum. However, when you get far enough into space that a vacuum exists, it is very cold due to either having no visible sun or being too deep into space to be close to a star. But when you are exposed to the sun in a vacuum, it would burn any exposed skin. Astronauts have to deal with huge temperature extremes in space; -250 in the shade, 250 in the sun, and so forth. Think of it this way: If a vacuum can't hold heat, how does the sun's heat reach us?
Furthermore, the lower the external air pressure, the lower the boiling point. At sea level, water boils at 212 degrees Fahrenheit, or 100 degrees Celsius. Drop the pressure enough and you can boil water at 100 degrees. When you are at a high elevation like the city of Denver is, your boiling point might only be 193 degrees or lower because of the high elevation of the city above sea level.
However, none of the above scenarios would apply because a severed arm would freeze solid in a matter of seconds if it were in deep space like the Terrans were.

uberlechuga is right, blood is red because of the Fe in the heamoglobin, not the Oxygen. and i also thought the cigarette still lit was an mistake, cuz fire needs oxygen to burn.

A common misconception is that blood turns red due to the iron in hemoglobin and its oxides. In fact, it is actually due to the porphyrin moiety of hemoglobin to which the iron is bound, rather than the iron itself. Porphyrins are just a group of organic compounds. In this case, I am referring to the heme, which is the pigment in red blood cells which is a cofactor of the hemoglobin protein. The heme is simply an iron atom in the center of a heterocyclic organic ring, which is called a porphyrin.
shareI always thought that part of the inaguration propaganda film was enhanced for special effects. It wasn't actual footage of an arm but rather added effecct to enhance the impact of Mengsk's speech of "togetherness"
My 2 cents at least.
