Would tiny life forms contribute to the amount of Dark Matter?
highly unlikely, but may be.....
The Speculation of Tomoko Adachi
I speculated that a kind of tiny organism such as "nanobacteria" or a kind of "extremophiles" could be one of many candidates of Dark Matter. This is still a very crude idea. I hope you can hel me to shapen the idea and give me a good way or methods to test my sepculation.
Waht is Dark Matter?
Materials made of protons, neutrons such as brown dwarfs, black holes and dubbed as MACHOs, Massive Compact Halo Objects.
Strange and exotic new material such as neutralino, subatomic and supersymmetric particles called WIMPs, Weakly Interacting Massive Particles.
We generally learn about the universe by seeing or detecting radio waves, infrared, optical, ultraviolot, X-ray, and gamma-ray emissions. Dark Matter does not emit any of above detectable emissions, simply put, Dark Matter does not glow. However, baryonic MACHOs can be detected by gravitational microlensing.
Tomoko's Arugument: Diagram1
We still don't know either Dark Matter is baryonic or non-baryonic, or combination of both. I think it probably is combination of both. I would like to focus on baryonic candidates at this time because the theory of non-baryonic matters are still being developed and requires information concerning "big-bang creation" thermal equilibrium and supersymmetry.
The baryonic matter such as brown dwarfs and wandering planets are detectable and increasing their numbers.
Nanobacteria and extremophiles are microbial life on Earth. Unlike the better known bacterial life, many of the archaea can thrive in extreme environments like volcanic vents and acidic hot springs. They can live without sunlight or organic carbon as food, and instead survive on sulfur, hydrogen, and other materials that normal organisms can't metabolize.
I would like to introduce some exotic organism and explain why I think that a tyny organisms could be a candidate for Dark Matter.
Recent discover of life forms
Extremophiles: Tiny organism that can live and maintain their lives in an extreme environment.
A bacteria was found inside the camera that is retrieved from the moon in 1969, mission Apollo 12. The camera was on the moon surface for two and a half years.
A long surviving bacteria was found in the gut of a well-preserved mastodon. The bacteria has survived for 11,000 years. They make colonies. If the population is sufficiently dense, the majority will release protectant and die. The restr can continue to live and multiply using nutrients from the dead comrades.
