Breathing Test
Pyrolytic-release experiment
Lifing things should breathe. That is, they take in gasses from the air
and incorporate it into their bodies.
Use radioactive labelling:
- Some elements have a radioactive form.
- The radioactive form is the came chemically as the
ordinary nonradioactive form.
- But the radioactive form decays (with a certain half life.)
- The decay can be detected because high energy particles are emitted.
- Example: C^14. Lets call it C*.
The experiment:
- Get some regolith.
- Put it in an atmosphere with C*O_2 and C*O.
- Supply some (artificial) sunlight.
- The life forms incorporate C* into the proteins (or whatever) in their
bodies.
- Let the regolith sit for a while in plain CO_2.
- Heat it to vaporize the life forms.
- Look in the gas given off for C* decays.
Control experiment:
- Get some regolith.
- Sterilize it with high heat.
- Put it in an atmosphere with C*O_2 and C*O.
- Supply some (artificial) sunlight.
- The life forms are dead and do not incorporate C* into
their bodies.
- Let the regolith sit for a while in plain CO_2.
- Heat it to vaporize the life forms.
- Look in the gas given off for C* decays.
Result: Some C* seen in the experiment, but some (although less) was also
seen in the control experiment.
So the result was rather inconclusive. It appears that the regolith is just
chemically reactive.
