Space

I think whatever happens, your blood will stay red. No point of becomming blue. So I think its a myth

From Nasa.gov:

“You do not explode and your blood does not boil because of the containing effect of your skin and circulatory system. You do not instantly freeze because, although the space environment is typically very cold, heat does not transfer away from a body quickly. Loss of consciousness occurs only after the body has depleted the supply of oxygen in the blood. If your skin is exposed to direct sunlight without any protection from its intense ultraviolet radiation, you can get a very bad sunburn.”

They have a whole page discussing this here: http://imagine.gsfc.nasa.gov/docs/ask_astro/answers/970603.html

Why would it be blue? At most, it would tend toward a little on the purple side as the hemoglobin lost some of its oxygen, but it would never be blue.

your blood wont be blue but darker red like you have a higher iron content (I realise you wouldnt) as for the vacum this is a predicted thing and it has not actly been tested therefore there is no definitive proof that there is a vacum in space for all we know when you go into space nothing will happen tot he human body but as there is no oxygen and no gravity it is a nationaly recognised theory and in all honestly is prabley the correct one

yes you will be pulled apart and yes your blood will be blue

im pretty sure blue blood isnt a myth…but you wont be pulled apart, no.
