Genesis life
finding life a second Genesis life that
isn't related to us some else somewhere
else will be will be to begin to
understand how biology can be different
I mean we don't even know if they'd have
the similar biochemistry but on the
other hand you know we're carbon-based
life-forms and carbon which is all over
the universe of course is great at
hooking up with other atoms to make
complex chemistry and since that's what
we are you know they might be
carbon-based that's not crazy we're
having a hard time figuring out what
other ways there might be we're working
on it from the bottom up with synthetic
biology trying to build life in other
ways but I think life elsewhere will
have evolved to be perfectly suited to
its environment
if the environments are similar to ours
then there could in fact be a lot of
similarities
if the environments are extremely
different from those that we enjoy here
on this planet then I think it's
unimaginable I'd love to find out what
we can't imagine in fact as we imagine
the kind of beings we make contact with
they may not be biological beings at all
on earth we are anticipating computers
becoming advanced enough that they may
even deserve the term intelligence in
the next century or so so if we make
contact with a civilization that's
thousands or millions of years more
advanced than we are the intelligence on
the other end of the line may be an
artificial intelligence these
hypothetical forms of life may have
abandoned their biological bodies a long
time ago to create a computer body they
may have the ability to build a quantum
computer with an extraordinary computing
power a super intelligent device with
the same capacity as a conventional
computer that occupies a whole planet
then they may have lost their
consciousness of the self to be absorbed
by a global digital network of minds a
great collective consciousness but in
terms of what they'd be like what they'd
look like nobody can release say except
this probably within a hundred years
we're going to develop Thinking Machines
on earth
here on earth so I think it's very
likely that if you actually pick up a
signal coming from elsewhere it's not
coming from some sort of biological
being it's coming from the Machine the
search for extraterrestrial intelligence
is not really different from the search
for our own future
the absolute ignorance about the
possible aims of an extraterrestrial
intelligence is what has led some
scientists to voice their misgivings
about announcing our existence to
extraterrestrials at least until we know
their intentions toward us
active SETI is a controversial topic no
less than the cosmologists Stephen
Hawking warned do not transmit to et you
know when he said that in 2010 his
concern was that aliens may invade earth
to strip-mine our planet taking our rare
resources
well Hawking is a genius but he can't
predict the future and so there's no way
he could have told that earth-like
planets are distributed everywhere but
even if there is a danger even if
another civilization can come to earth
it's too late to conceal our existence
any civilization with the ability to
travel between the stars can already
pick up our radio and TV signals that
are leaking off into space there is no
added danger of transmitting signals
through active SETI
in any case considering the data we now
know a first contact may be possible in
a short time it's also possible that some
civilization has already listened to our
messages nevertheless how is it possible
that if there are other civilizations we
haven't yet received any evidence of
their existence this is what is known as
the Fermi paradox the physicist Enrico
Fermi famously asked where are they the
idea was if in fact the universe is
populated with life why haven't they
come here the formulation of that
paradox arose when the physicist Enrico
Fermi was working on the Manhattan
Project whose aim was the development of
the u.s. atomic bomb Fermi's answer to his paradox was that
every advanced civilization develops along with its technology the potential
to exterminate itself as was thought to
be happening at that time the fact that
other extraterrestrial civilizations had
not been found implied for him a tragic
end for Humanity
however there are several possible
solutions to the Fermi paradox they do
exist but they are not communicating
with us they do exist and communicate
but we can't hear them they do exist and
have been here but we weren't they do
exist but most people don't know it yet
they have disappeared
maybe these civilizations have already
Destroyed themselves
destroyed themselves as a consequence of
a nuclear war or some other cause but we
find even more solutions to the paradox
well there are a lot of answers to the
Fermi paradox you know one is that it's
actually very difficult to travel
between the stars you know even over the
course of long periods of time it takes
a lot of energy it takes a lot of
commitment and anything that you can
gain in terms of information you could
get a lot cheaper simply by sending
radio signals another possible solution
is that we aren't interesting to them if
some civilization were able to come to
the earth from the stars it would have
to be thousands or millions times more
advanced than ours and we may not have
anything interesting to offer them such
a civilization might consider us as
primitive as we consider a simple
beehive would it make any sense for us
to interact with bees and try to make
them understand our advances in
spacecraft missions nuclear energy or
quantum mechanics or maybe there is
colonization and we just don't happen to
see it because it's not nearby or it
isn't very obvious
paradoxically the galaxy could be filled
with intelligent forms of life but we
are so primitive that we have not even
realized it another explanation for the
Fermi paradox is that we may have
already received those signals but we
haven't realised it we haven't perceived
the signals or we haven't been able to
understand or decode them
in this case some strange signals from
outer space have been received their origins are now being investigated and
they have posed serious questions for
scientists the most famous signal that's
been detected came in 1977 it was at
Ohio State University's big ear radio
telescope and in the course of listening
for signals from another civilization
there was this message that was strong
that was spread out over frequency it
looked exactly like the kind of signal
we would want to get from et during his
work on the night shift on July 15th
1977
Jerry R Eamonn professor of the state
university of Ohio and SETI project
volunteer observed the weird
transcription of the radio signal made
by a computer in a section of paper feed
to confirm later that it was the most
intense anomalous signal detected up to
that point by a radio telescope the
signal of unknown origin had a duration
of 72 seconds and reached an intensity
30 times higher than conventional
signals and had come from the
constellation of Sagittarius in fact it
was so astounding that when the
technician was looking at the printout
the next morning he wrote Wow in the
margin and that's become known as the
WoW signal the computer processed the
signals received into a series of
alphanumeric characters it wrote the
sequence 6eq uj5 which has kept the
international scientific community on
edge until today
'man and his team studied the signal in
detail in the end they were able to rule
out that it had been part of any
interference coming from the earth so
during the following month the operators
of the radio telescope tried to
reposition the signal but they didn't
succeed well many times in the decades
since then astronomers have looked at
the same part of the sky to see whether
they can find the WoW signal again
but we've never been able to replicate
it so the key to progress in SETI is to
be able to find a signal that looks as
good as the vowel signal but now to be
able to find it not just once but over
and over and over again today the origin
of that signal is still under
investigation
kind of interesting signal
