thrive on and thrive out while you still can,
for the cosmos is expanding like a memory that fades
a memory like
your lover being yanked out of your hands by a forward-clanging train
you choke on puked out smoke and steam and hold back dirtied tears
while a painful hasty nothing grows between what once was One
felt unsure if you could ever catch again the outstretched fingers
they once were yours…
the rockets flying right past stars nearly at light-speed
are struggling to connect anything
much less merge the species of far-flung galaxies
scoop up eons of light to go and eons more coming back
after all this travel time will we be any closer?
the lover also wants to know…
sometimes i wonder whether we should sit and wait for ansible
or other instant protocols for instant message needs
to talk not just to future times that won’t know who we are
but to every living crawling swimming flying walking thing
not the least of which is all the forms that we will take someday
i’m afraid that if we wait too long even we humans won’t be one,
we’ll be humans A and humans B,
or worse, at this rate,
humans A and humans Z
and one will sign and one will talk
and one will smell what you mean and the other just baulk
at the way those other guys try to communicate with their noses and their complex pheromones
and if we stay spread apart in time and space it won’t be long till everything
is a universe apart
oh, being apart…
even to you today your other half is half-alien
not even two continents away
the alien beeps and groans still sputter out down from your speakers
despite such wicked throughput, the quickest ping, and best intentions
skype is just not true to life
and it’s looking like what’s not so close is far too far away
what’s a man to do?
can we keep the light years at bay?
some will say to multiply in people and in rockets,
to exponentialize our meager efforts and
to try to reach the stars that are breaking off and slipstreaming away
it seems it comes down to this notion that we must always grow
and be the beings that end up being all and everything
lest we find ourselves stuck entropically
on some lonely swimming rock in space
crumbling till our final grain of sand
becomes the finest mote of dust on hand
to be exhaled in the universe’s
final tiny breath.
but how much force can the soul withstand while plastered to the sky?
and can we learn how to drench with love the distant planets’ hearts and minds?
to join, unite, and conquer this darkness
the forced separation a lover feels
can it be made right?
will we find a way to create light?

The Fermi Paradox, Phase Changes and Intergalactic Colonisation
A new model shows how the spread of ET civilisations can undergo phase changes, providing deeper insights into the Fermi Paradox
In 1950, the Italian physicist Enrico Fermi raised the question that now bears his name. If there are intelligent civilisations elsewhere in the Universe with technologies that far surpass our own, why do we see no sign of them?
Since then, the so-called Fermi Paradox has puzzled astronomers and science fiction writers alike. And although there are no shortage of ways to approach the problem, nobody has come up with a convincing explanation.
Now there is another take on the problem thanks to a new approach by Igor Bezsudnov and Andrey Snarskii at the National Technical University of Ukraine.
Their approach is to imagine that civilisations form at a certain rate, grow to fill a certain volume of space and then collapse and die. They even go as far as to suggest that civilisations have a characteristic life time, which limits how big they can become.
In certain circumstances, however, when civilisations are close enough together in time and space, they can come into contact and when this happens the cross-fertilisation of ideas and cultures allows them both to flourish in a way that increases their combined lifespan.
Bezsudnov and Snarskii point out that this process of spreading into space can be easily modelled using a cellular automaton. And they’ve gone ahead and created their own universe using a 10,000 x 10,000 cell automaton running over 320,000 steps.

“Part and parcel of the what leads many to an Extropian mindset is the realization of scale, both in space and time. We’re allotted seventy to a hundred years of life compared to a fantastically large number of years that the Universe has been in existence. We live on a tiny little planet in a universe so large that the movie above doesn’t even begin to do it justice.
We’ve made up mythologies, religions, politics, cultures and national borders to limit our perspectives so that the enormity of scale doesn’t overwhelm us.
Once it has overwhelmed us – and the movie above is definitely a good starting point – it becomes difficult to understand why two artificially constructed groupings of humans want to fight each other. We really only need to take a step back and realize how similar we actually are.
We’re all one people, one human race that – for now – is locked to a small planet, one of the planets in an insignificant solar system in the corner of a young galaxy called the Milky Way.
Some day in the future, we will be more than this, so let’s try to overcome our territoriality and caveman brains before we get there, okay?”
– by Breki Tomasson, as seen on The Extropist Examiner
Mind, through the long course of biological evolution, has established itself as a moving force in our little corner of the universe. Here on this small planet, mind has infiltrated matter and has taken control. It appears to me that the tendency of mind to infiltrate and control matter is a law of nature.

We are on the edge of change comparable to the rise of human life on Earth.

Self-organization and extropy are themselves fundamental principles of the physical universe, to the extent that the laws of physics themselves may have developed through a process of self-organization.

The explosive nature of exponential growth means it may only take a quarter of a millennium to go from sending messages on horseback to saturating the matter and energy in our solar system with sublimely intelligent processes. The ongoing expansion of our future superintelligence will then require moving out into the rest of the universe, where we may engineer new universes.

Technology expands data by 66% per year, overwhelming the growth rates of any natural source. Compared to other planets in the neighborhood, or to the dumb material drifting in space beyond, a thick blanket of learning and self-organized information surround this orb.

The universe might end in intelligent life (rather than as either a ball of fire or as scattered ice). Not life as we know it, but life that has acquired the capacity to shape the cosmos as a whole, just as life on Earth has acquired the ability to shape the land, the sea, and the atmosphere.
— James N. Gardner
The surface of the Earth is the shore of the cosmic ocean. Recently, we’ve waded a little way out … and the water seems inviting.
