Life in other planets
In several articles I argued, based on the theoretical
approaches of Thomas Gold and Fred Hoyle, that life is possible in all
celestial bodies with temperatures below 100-200 degrees Celsius. When the
surface temperatures of the planets, satellites, asteroids and comets are very
cold (for example, below 50-100 degrees below zero centigrade), the internal
heat can melt the ice generating accumulations of groundwater that would allow
the existence of organisms alive
In order for life to be possible, the conditions are
required for liquid water to exist.
This applies to the solar system and all other analogous
star systems and to the independent or rogue planetary celestial bodies (which
are not part of any star system).
That is, there would be trillions of planetary stars (only
in our galaxy) that could potentially harbor living organisms inside them.
On Mars, for example, there could be living underground
organisms at depths of the order of a few hundred meters (where the conditions
for liquid water are given). On the Moon, in Ganymede, Europe (satellites of
Jupiter), Titan. Triton (satellite of Neptune), Pluto and other celestial
bodies similar conditions for liquid water may also occur at depths of a few
hundred meters or a few kilometers.
That is, life would exist everywhere where the temperature
and pressure are adequate for liquid water to exist.
It is not logically admissible, as it is maintained in the
official geography, that life has originated on Earth or that our planet has
exclusivity in that aspect. These hypotheses (I would say beliefs) that the
Earth is unique in relation to life is the last vestige of the ancient
geocentrism.
Interesting is to reflect on the possible existence of life
in comets. They are small bodies (generally less than 10-20 km in diameter)
that do not have much internal heat but that seem to contain a large percentage
of organic molecules (VERY rich in carbon). Surely comets carry the basic
elements of life and perhaps organisms in dormant or active life, probably in
the form of spores, and in some cases even viable microorganisms. We do not
know. But the coherence of nature and the universe makes us think that life is
(almost) everywhere. As Fred Hoyle maintained: "Life is a property of
matter" -
