Space and decomposition of matter?

The body would freeze-dry and be completely impervious to rot. All bacteria that cause rot would be freeze-dried also. Radiation only hurts living tissue. A space coating would form on the body in the direction of travel (dust) and if the body was rotating the dust would be uniformly distributed.

Just like you, I can only speculate. The cold and "absolute" dryness of Space would prevent the body from decomposing. If it was in a space suit or coffin, that would prevent normal decomposition but cosmic rays would be more intense thus contributing to dessication,

If the body was in a full vacuum then no I do not believe that it would. however yes if it was in a spaceship or coffin. most decomposition occurs from the inside out.

Starry-eyed is correct, "The body would freeze-dry and be completely impervious to rot."

Also, gravity is not what holds your body together. A human body is WAAAAAAAAYYYYYY too small to have enough of its own gravity that would be strong enough to hold anything together.

.

it would pull apart due to a lack of gravity. It would probably not decompose because the bacteria in the body would die.

decomposition depends on bacteria, the body would be solid and so would the bacteria
