Question

If you were in space and cut yourself would you bleed blue?

Answer 1

No, firstly hemoglobin doesn't turn blue when de-oxygenated, it actually turns a darker red and secondly your blood would still be oxygenated when it came out of you.

Veins in the skin appear blue for a variety of reasons only weakly dependent on the color of the blood. Light scattering in the skin, and the visual processing of color play roles as well.

Answer 2

If you are in a spacesuit you would bleed red. If you were outside of your spacesuit you wouldn't be able to cut yourself because you would expand in the vacuum that is space. :D

Answer 3

Forgot to mention the explosion part ^

Answer 4

I was thinking the same thing cr1! So vg9, where in space do you mean? or rather why do you think it would? due to the lack of O2 in the air or the weightlessness?

(Explosive decompression! -- just because I wanted to say it :P )

Answer 5

Had me thinking of the movie Event Horizon when I saw the question. All of the blood is oxygenated within the body, so it would be red when it came out...all at once...in a 'splosion.

Answer 6

Eeeewww o.O

Answer 7

only one person has ever been subjected to very low pressures near vacuum so in reality we knew very little about what would happen to the human body after it has been exposed to the vacuum of space. just a heads up ^^

Answer 8

Of course its all in theory. Not that many volunteers that want to be ejected into a cold oxygen-less environment!

Answer 9

Who knows it could be fun *jumps* that being said there are probably a few scientists out there that are curious enough :P

Answer 10

Haha the astronaut subjected tot he near vacuum temperatures reported feeling the saliva on his tongue begin to bubble... soo maybe not so much fun.
