Will SETI Find Any Aliens Ever?
Californian
Institute SETI might someday host a conference dedicated to discovery
of other civilization. Each year, the likelihood of this event decreases
along with the loss of trust to the project designed to search for
extraterrestrial life. Pravda.ru interviewed Alexander Uvarov, a
radio-astronomer, to find out why.
In 1609,
Galileo Galilei saw the starry sky through a telescope he invented for
the first time. A year later, the famous astronomer was swamped with
orders from scientists, kings and nobility who also wanted to look at
the Universe through a telescope.
It has been 400
since that moment. Astronomer had a chance to peep into the farthest
corners of space, but never managed to discover signs of alien
intelligence. Over the last 50 years, project SETI has been listening to
the radio of the Universe trying to catch signals of a developed
extraterrestrial civilization, but to no avail.
Now
scientists say increasingly more that project SETU was initially based
on a wrong, excessively refined image of space. There can be numerous
explanations as to why there is no evidence of other life. One such
explanation suggests that we simply do not have any “neighbors.”
Astronomers
do not rule out that the very principal of the quest is erroneous.
There are no guarantees that other civilizations would use the same
frequency as SETI. The radio that was considered to be cutting edge 50
years ago does not necessarily represent a standard for inter-galaxy
communication.
Project SETI was based on sheer
enthusiasm of people who were sure that they would achieve results in
the first years of its existence. Yet, there is no single scientific
hypothesis that would confirm that the method is the right one. The
management of the project is not concerned about it and continues to
insist that listening to space cannot be stopped, and that soon the long
wait will pay for itself.
Are these expectations
justified? Pravda.ru asked Alexander Uvarov, a radio-astronomer an
employee of the Institute for Radio and Electronics, to share his
opinion.
"The latest research reveals that
theoretical signs of other civilizations should be very apparent. The
fact that SETI’s search was not successful most likely speaks of wrong
methods.
Currently, there are many other
technologies that may help find extraterrestrial life. For instance, a
marker of specific substances contained in exoplanets that can only
appear as a result of complex industrial processes. I think that future
research must be complex and involve consecutive application of all
methods in the chosen range of space.
I would
like to hope that SETI project can bring sensational discoveries in its
current form. The latest technologies designed to eliminate
interruptions could play a significant role in it. These technologies
are now being implemented, and it is not ruled out that they will allow
us to hear voices of other civilizations.”
