how long could you survive in space?

Answer 1

To experience the vacuum is to die, but not quite in the grisly manner portrayed in the movies Total Recall and Outland. The truth of the matter seems to be closer to what Stanley Kubrik had in mind in 2001: A Space Odyssey.

According to the 1966 edition of the McGraw/Hill Encyclopedia of Space, when animals are subjected to explosive decompression to a vacuum-like state, they do not suddenly balloon-up or have their eyes pop out of their heads. It is, in fact, virtually impossible to compress or expand organic tissues in this way. Instead, death arises from the response of the free gasses trapped within the tissues.

If decompression takes 1/2 second or longer, even lung tissue remains intact. When the ambient pressure falls below 47 mm of mercury (similar to the pressure at the surface of Mars), the water inside all tissues passes into a vapor state beginning at the skin surface. This causes the collapse of surface cells and the loss of huge amounts of body heat via evaporation. After six seconds, the process of cell collapse involves the heart and lungs causing circulatory interruption, followed by acute anoxia, convulsions and the relaxation of the bowel muscles. After 15 seconds, mental confusion sets-in, and after 20 seconds you become unconscious. You can survive this for about 80 seconds if a pressure higher than about 47 mm mercury is then reestablished, otherwise, you turn into freeze-dried dead meat on a stick.

So forget the fairy tales people!

Answer 2

Two three minutes tops. Are you think SPACe without a SUIT.

If you talking with a suit, I think I'd go stir crazy after two weeks unless I could take off the suit and walk around.

I think I could hack a flight in a ship the size of a bus for maybe 6 months if I had a lap top computer to work with and lots of DVDs to watch.

Answer 3

i don't know how long for sure, but space is a giant vaccum with absolutely no air pressure, has extremely high radiation everywhere, enough to give you cancer in about 2 seconds, and is about -200 degrees to -300 degrees between the moon and the earth. then if you go between the earth and venus, it's about 200 degrees or more. the earth is in the exact perfect place for life. to sum it up, you wouldn't live over a minute, or maybe not even 2 seconds.

Answer 4

The Earth has been floating round in space for a pretty fair amount of time and we are still here.

Answer 5

space isnt cold as it were, space is the absence of heat if that makes any sense. as theres no water molecules or air in space my guess would be you'd freeze in a very very fast time. perhaps 10 seconds. most people assume that in space because of the lack of air and pressure you'd implode/explode, i believe you would freeze because of the extreme lack of heat would chrystalize every cell in your body as solid ice. but as ice expands it would probably turn your body inside out. you would be a blob. a solid block of frozen blob in 10 seconds or less.

Answer 6

A couple seconds. Your body's internal pressure would cause you to explode in the near vacuum of space.

Answer 7

Without a spacesuit, About 17 seconds max :
- You would become unconscious within 15 seconds because there is no oxygen.
- Your blood and body fluids would "boil" and then freeze because there is no air pressure.
-Your tissues (skin, heart, other internal organs) would expand because of the boiling fluids.

Answer 8

Without life support systems (I assume you mean): less than submerged in water on our own planet.

Say, 120 seconds!

Answer 9

30 seconds, no pressure, and very cold. The first thing that happens is your eyes freeze over.

Answer 10

Well judging by my height and weight, the distance I am from the sun, my IQ, my favorite TV show and the amount of fingers I have I'd have to say about............
