What would happen if a man went into space without a specialized suit?

you’ll freeze to death before you run out of air and before gravity crush you(if your in a gravitational field of that proportion

You die of anoxia (low level of pO2) in about 90 seconds.

studie show if you ever go out of the atmoshpere with out a specialed space suit yu WILL implode/explode ect with in a few min inside or outside of the spaceshiip.

once ur in space..theres no force there to keep ur body intact n compressed..so w/o the suit..ur body’s natural outward thrust wil take its toll n ur eyes..veins..evythin will burst n u ll be dead meat in minutes!! Id say it ll take less than2 mins

You could not implode - that requires an external pressure much greater than the internal pressure. While we are at sea level, our internal body pressure is in equilibrium with the external air pressure - around 15 pounds per square inch.

If you went into space in a (15 pound per square inch) pressurized capsule, and were then suddenly dumped outside into a near vacuum (near zero pounds per square inch) your 15 pounds per square inch internal body pressure would tend to cause your body to EXPLODE.

To get an idea of the force: imagine a 10 inch by 10 inch area in the middle of your rib cage - the total force pushing your rib cage outwards across that area would be: . 10in x 10in x 15 lb / in² = 1500 pounds which is about ⅔ ton. It is debatable whether that would cause your rib cage to explode, however you cranial cavity would almost certainly be able to remain intact and protect your brain for a short time.

You would probably not be able to hold what little air you had inside your lungs and that would rapidly escape via your nostrils and lips.

The sudden pressure change and rupturing blood vessels would probably cause “shock” and loss of consciousness, but whatever degree of shock was caused by the trauma, you would lose consciousness and become brain-dead within about 5 minutes.

You would not die of cold in deep space - your body would only lose heat by “radiation” there being no air through which thermal energy could be lost by conduction or convection.

Your body heat would be preserved for quite a long time in a manner similar to the preservation of heat in a Thermos “vacuum flask”.

This shot from a dream sequence in the film “Total Recall” is probably as close as you are likely to get to imagining the low pressure vacuum scenario in your question.

If you remained conscious until your death you would be aware of the outwardly acting forces due the imbalance of external and internal pressure and the trauma of rupturing capillary vessels. You would die due to lack of oxygen ( asphyxiation ) whilst becoming acutely aware that your attempts to breathe were totally futile. Your mind would probably cause you to experience rapid “flash back” of life experiences - you parents, childhood, sexual partners time with your own children etc.. Lack of oxygen would cause anaesthesia and the initial pain would diminish significantly - most probably becoming a xix or fear and “euphoria” during the final few seconds.

If I could like your answers multiple times, I so would. Every time I read one, I go back to check your age again, because your occasional humor makes me think you’re my age, but then your answers…dear lord, there’s no way you would have this much information in there if you’d only been on this earth as long as I have. Sorry for the random rant, but you’re my favorite, officially.
