ANDRE BORMANE: I think that it is ail but a certainty
-that alien life exists in our universe. -(g rowl s)
The universe is so vast,
there's so many countless billions
of planets orbiting other stars.
The chemistry of life is really fairly simple.
wasps) -(trills)
We know that the conditions under which life began on the Earth
exist in billions upon billions of other places in our universe.
And I think that we will probably have evidence of microbial life at least...
within the next 10 to 15 years
either on Mars, one of the moons of Jupiter or Saturn,
or in some other exotic environment like that.
Alien intelligence? That's a much harder guess.
ISAAC: My planet regards humans and other biological life forms as inferior.
Oh, that's great. Thanks.
I suspect that intelligence like ours is probably pretty rare,
because if it were common, I think we'd know about it by now.
It's probably rare in the sense that there are so many stars,
so many galaxies in our universe,
if even one in a million stars in our galaxy
had a planet where intelligent life evolved,
well, that would be tens of thousands
of intelligent civilizations across our galaxy alone.
But the distances are so vast
that the idea that we could sort of be at this level of technological development
where we're using radio waves, for example, to communicate,
and another civilization in another pan of the galaxy
is at the same state of development,
but if it's 5,000 light-years away,
they would have to be 5,000 years ahead of where we are now
for us to be getting their first radio signals.
There has to be these extraordinary coincidences in time for us to be able
to communicate with those kinds of civilizations at those distances.
But if I had to bet money, I'd bet it all on, "Yes, we will discover alien life."
You guys, we're on the edge of the frontier of explored space.
That doesn't excite you?
