An excellent time travel movie: Timecrimes

I watched Timecrimes on Netflix streaming video.  It was excellent. It met many of my criteria for a good time travel movie:  It had a time machine and they used it several times, there was a time loop and the protagonistic had to work hard to eliminate and prevent any paradoxes.

The middle of the movie was really slow but presented a lot of details which were critical to the ending.

The movie is in Spanish, looks like there will be a new English version in 2011.

Vote against your incumbent

Here is my hopeful prediction of Nov 3, 2010, the morning after the 2010 mid-term elections. Speaker Pelosi and Minority Leader Boehner hold a joint press conference to discuss the stunning results of the elections.  71% of incumbents were voted out of office.  Republicans took control of congress with a 235 - 200 majority.  66% of Republican incumbents were voted out of office, 75% of Democratic incumbents lost their seat.  Only 114 incumbents were re-elected, and more than half of those won by less than 1%.

Speaker Pelosi takes the podium first.

"Good morning.  I've asked Minority Leader Boehner to join me here today so we can jointly address what can only be considered as the most stunning mid-term elections in the history of this great country.  With 75% of my fellow Democrats losing their jobs I can only say that this speaks to the core of anger and disgust Americans feel about Congress.  Despite overwhelming majority populations many congressional districts held by Democrats for decades will switch hands to a Republican representative next January.  Even my own district almost elected an independent, I only won by 0.3% of the vote.  When questioned about issues the voters showed strong unhappiness with the scale of the new health care reform bill.

I accept full responsibility for this failure, it's clear that Democrats failed this country.  I will not stand for any leadership position in the new Congress.  My goal is to mentor the 175 newly elected Democrats as they begin helping this country as quickly as possible."

Minority Leader Boehner now takes the podium.

"I would so much love to brag about our great victory today, we took control of the House and voted out so many Democratic incumbents.  But I think only a fool would regard last night's elections as a victory for Republicans.  66% of my colleagues, including myself, were voted out of office last night.  Our policies and methods of opposing the health care reform bill were frequently mentioned as reasons for voting for Democrats.  We failed the American people and we failed our party.  Democrats now control districts with overwhelming Republican majorities.  Congress has been devastated, burned to the ground, and remade whole again by the will of the people.  As I leave office I can only take a small measure of comfort in thinking about the fresh new faces who will take office in January and restore American confidence in our Congress.

I apologize to everyone for this failure.  And I am sure this is a great day for our country."

Wishful thinking.  If only people will do it.  Please vote your incumbent out of office even if it means voting against your party.

Where are the aliens?

"Peering far beyond our solar system, NASA researchers have detected the basic chemistry for life in a second hot gas planet, advancing astronomers toward the goal of being able to characterize planets where life could exist. The planet is not habitable but it has the same chemistry that, if found around a rocky planet in the future, could indicate the presence of life."

If organic molecules are so prevalent where are all the intelligent space-faring aliens ?  The lack of evidence for aliens is strong evidence that we are alone, the random evolution of intelligent life is so rare that we are the only ones in the entire galaxy.  Note that this is not the same as saying "the random evolution of life is rare".  There probably are bacteria in most solar systems.

Atheists and the Fermi Paradox

The basic argument of an atheist is "If there is a God then prove it, where is the evidence?  I can't see him, I've never seen a miracle, there is no evidence of supernatural powers or beings."  Replace those words with aliens and you get the exact same argument.  Anyone who argues against the existence of God has to give the exact same arguments against the existence of aliens. I'm in the opposite category, despite my faith I say "There are no aliens in this galaxy, prove me wrong."   It's unreasonable to say that even one other intelligent species evolved in our galaxy because that requires wild coincidences about why they aren't here.  Some of those coincidences say:

1 They evolved at almost exactly the same time as we did (beating the odds of 13 billion to one)

2  they aren't explorers, they just stayed home, and they never sent out robotic exploration ships

3  they killed themselves (war, suicide, plague) before launching robotic exploration machines

4  they all died because of natural events (asteroids, supernovae, plague) before launching robotic exploration machines

5  their robots came and left before we noticed and left no evidence of their visit, and are probably secretly watching us

6  they have a Prime Directive and they won't visit us until x happens .... and maybe never

Many people confuse the evolution of life with the evolution of intelligent life.  They say life evolves easily and that life is everywhere in our galaxy, but they are not talking about intelligent life, they are talking about bacteria.   The Rare Earth explanation for the Fermi Paradox is not about planets, it's not about atmospheres, and it's not about bacteria.  It's about space faring sentient life.  I could not care less if there are bacteria in every stellar system in this galaxy.  That is boring and has nothing at all to do with the Fermi Paradox.

The evolution of intelligent life is rare, extremely rare.  So rare that the rate per galaxy is well below 1.0 per 13 billion years.  If FTL is possible then the Fermi Paradox requires that the rate of evolution of intelligent life is about once in 13 billion years per universe.  That means we are alone in the entire universe.

Prove me wrong with evidence, not conjecture.  Don't tell me what "we all know to be true" especially all you atheists, because you won't accept that argument for the existence of God.

Have physicists discovered alien life?

Work published in 2008 from Israel claims detection of element #122.  If true the implications are stunning.  The only possible method of generating element 122 is by artificial nucleosynthesis, a technical feat beyond the capability of modern day humans. While subsequent study may have disproven the theory this opens up a new method of proving the existence of aliens.  Even a single atom of element 122 (or higher) would be an artifact proving the existence of alien life...

Or time travel, it's always possible that in the future human will make the element and then send back in time either coincidentally or as an actual component of the time machine.

Regular readers of my blog know that I propose there are no aliens anywhere and never have been.  So if element 122 is really discovered I claim it's proof of time travel, not aliens.

Scifi Optimists versus Scifi Pessimists

Scifi pessimists say - we'll never be able to feed 8 billion people. Scifi optimists invent algae which can fix nitrogen from the air, generate fertilizer, and live in a symbiotic relationship with roots of food plants in airborne greenhouses.

Scifi pessimists say - global warming will kill us all.

Scifi optimists invent CO2 scavenging algae which generate carbon nanotube filaments used for building space elevators.

Scifi pessimists say - the sunspots won't come back and we'll all freeze in another ice age.

Scifi optimists invent CO2 storage bins which absorb or release tons of CO2 every day for precision climate control.

Scifi pessimists say the ozone layer will disappear and we'll all fry.

Scifi optimists invent airborne ozone replenishing units staffed by extremely attractive people.

It's too bad there are so few scifi optimists.

Darwinism and the Fermi Paradox

For those who might misinterpret my prior comments on Darwinism here's a clarification. The philosophy of Darwinism leads many people to use the word "paradox" to describe the lack of alien visitors. They all "know" that the evolution of sentient life is easy, so facile, that the Milky Way "must be" teaming with intelligent life. Therefore the lack of alien visitors to Earth is a paradox.

So here's the real science. There is no evidence that any aliens have ever visited our solar system. There is no evidence of artificial constructions in any solar system, star cluster, or interstellar location in the Milky Way. There is no evidence of any artificial construction in any galaxy we can see.  There is no SETI signal, there is nothing.

The overall statistics of these observations lead to the following conclusion: the evolution of sentient space faring species is so rare that we might be the only one in the entire universe. The implications for Darwinism are devastating. While the evolution of bacteria might be trivial, and every solar system in the entire universe might contain primitive life, the evolution of intelligent life appears to be nearly impossible.

For over 10 billion years our Milky Way has been easily capable of supporting space faring explorers. Robotic spacecraft could explore the entire galaxy in about 100 million years. If they aren't here yet this means they waited at least 99% of the life of the galaxy before starting. Why did they wait? Statistically it's possible that we are the first, or one of the first, and nobody has been around long enough to explore the entire galaxy: statistically possible, and highly improbable. Either every single species has an impediment to building robotic exploration craft (remember it only takes one) or there aren't any.

For 10 billion years no extra-galactic species has constructed an object visible from Earth. Perhaps such structures are impossible. I doubt it. This is evidence that there are no aliens in other galaxies.

I claim there aren't any aliens anywhere in the entire universe, we are alone, and there is no evidence to the contrary. Many people have speculations, deeply held beliefs about Darwinism, Drake equations, planetary search data, ... but in the end these speculations are irrelevant. Visual observation is all that counts.

So the implications for Darwinism are this, the rate of evolution of intelligent space faring species is about once per universe per 13 billion years. It appears there are millions or billions of planets/galaxy capable of supporting an evolving ecosystem. So for any given planet in the entire universe the chance of evolution of intelligent life is about 100,000,000,000,000,000,000 to 1.

We didn't beat the odds, we just had the winning lottery ticket. If you bought 100 million lottery tickets you would not be surprised to find that one of them had the winning numbers. Out of billions of planets ours held the winning ticket in the Darwinian lottery.

More ideas on the Fermi Paradox

Many recent blog posts continue to try to explain the Fermi Paradox.  I'll try to explain why these writers just don't get it. http://enfranchisedmind.com/blog/posts/the-fermi-paradox/

Many people still are confused on several points about the Fermi Paradox.  Let's start with the name.

The word paradox is used because everyone "knows" it's a "fact" that there are countless intelligent aliens in our galaxy, despite the fact that none of them have made any obvious contact with humans or visits to Earth.  The use of the word "paradox" is sloppy pseudoscience.  We don't know, in fact pure empiricism suggests we know the opposite.  The complete lack of evidence of aliens in our galaxy is overwhelming evidence that we are alone.  The phrase "Fermi Paradox" has become so ingrained that it is almost a single word, and it will be difficult to eliminate it.  So I'll keep using it even though I'm convinced there is no paradox.

The reason so many people believe in this "fact" is pure and simple.  Darwinism has blinded us to objective science.  We all "know" Darwinism is true, and we "know" that it's "easy" for intelligent life to evolve.  Therefore we cannot possibly be alone.  Let's try to be scientists on this topic.  Regardless of your opinion on Darwinism, the obvious evidence is that we are alone.

There is no evidence of intelligent alien life anywhere within or without our galaxy.  Look around, and specifically look at other galaxies.  We have excellent images of roughly 10,000 galaxies.  Not one of them shows an artificial construction.  Assuming each galaxy is 10 billion years old, that means that not once in 1e14 galaxy-years has an alien race built a galactic superstructure, visible from our galaxy.  Not once.  How can any scientist look at this evidence and claim anything other than "humans are alone" ?

And let's be clear, the existence of alien bacteria on a rock orbiting Alpha Centauri has nothing to do with this discussion.  I could not care less if every star in this galaxy has primordial life, or even highly evolved tool makers.  This is only about intelligent, sentient, technologically advanced space-faring civilizations.  Bacteria are irrelevant.

Another point of confusion is the difference between "manned" exploration of the galaxy versus robotic exploration.  Frequently bloggers cannot distinguish between these.  They say that there are not enough aliens to staff the exploration ships, therefore the exploration of the galaxy will be a lot slower than "commonly" accepted.  Again they "know" that aliens would probably not send out self-replicating robots to explore the galaxy.

The fact is that even one self-replicating robotic exploration craft would find every solar system in our galaxy in a matter of 100 million years.  That means that for the first few billion years of the existence of the Milky Way no sentient race has built automated exploration craft.  Or does it?

A statistical analysis of the evolution of humans from self-replicating RNA demonstrates that evolution is wrong.  There are too many permutations available which lead to dead ends.  Two billion years on a single planet is not enough time for all the dead ends to be explored.  The current theory of Darwinism requires that life "randomly" chose a viable path 99% of the time, instead of a dead end.  Most mutations don't work, they result in dead babies, or sterility, or severe biochemical imbalances.  Yet evolution on Earth has mysteriously chosen a viable living mutant baby most of the time.  What an amazing coincidence !

But what if we combine statistics with the Fermi Paradox?  Suppose our galaxy has seen the existence of 1-2 intelligent species that built self-replicating robots.  And instead of hardware, the primary substance of those self-replicating robots is biological?  Suppose that instead of 2 billion years on one planet, evolution has really had 10 billion years on a million planets.  Now the statistics make sense, now we no longer need a miracle of statistics to explain our own biology.

So here's the resolution of the Fermi "Paradox".  In the Milky Way (a few million planets over the past few billion years) intelligent life evolved once (or maybe 2-3 times).  That species built self-replicating biological explorers which seeded the galaxy.  We are the result.  Humans are either direct products of alien robotic exploration craft, or we are the first and only intelligent species to evolve in the entire universe.

I prefer the second, I say that the rate of evolution of intelligent life in the Milky Way is about once per 13 billion years.  So prove me wrong, with evidence.  Real evidence.  And don't waste my time talking about what we "know to be true".

Joe Haldeman's Accidental Time Machine

Just finished listening to Joe Haldeman's "The Accidental Time Machine" from Audible.

As a time travel story it was excellent, there was a time machine, multiple uses of that machine, time travel was a key element of the story, and there was even a time loop. The overall story dragged at many points, especially when he fell into the trap of anti-Christian ranting.  Then it rushed far too quickly through the climax.

Why is it that smart scifi writers can't imagine a world where Christians are heroes and live respectable lives? At least the anti-Christian stuff was relatively tame and the rest of the book was good enough to overcome it.  The narrator was well casted, he sounded about 23 and exactly like a physics graduate student.

New Dune Novels

I haven't read them yet but here are 2 new Dune Novels, written by Frank Herbert's son Brian, and Kevin Anderson.  Paul of Dune is a sequel to Dune (prior to Dune Messiah) while the soon to be released Winds of Dune takes place between Dune Messiah and Children of Dune. I will read them when I have time.  Hopefully they'll write a sequel to Children of Dune, I'll buy that one immediately, as a hardback.  I find The Tyrant to be the most intriguing character of any science fiction book I've ever read.

Has Optical SETI discovered aliens?

Optical SETI offers a much higher chance of finding a real signal because of the simple fact that there are no known natural sources of nanosecond pulses (or shorter).  Any 10 nanosecond pulse of light can only be from intelligent life (or of course a shocking new natural phenomenon). Recently a researcher in Australia has detected a pulse.  Unfortunately the details of the signal are not available.  Thanks to Sentient Developments for pointing out this article.

The details of optical SETI are a lot more complex than radio based SETI.  Radio SETI is fairly clear, just listen for a signal which shouldn't be there.   But optical SETI requires some understanding of light pulses.  For example, every day our own sun puts out flares, which would look like pulses from a few light years away.  Supernovae, gamma-ray bursters, novae, and variable stars all put out more light at some point than normal.  So what makes an optical pulse natural versus synthetic?  The answer is time.

There are no natural phenomena which generate nanosecond light pulses**.   A nanosecond pulse means that a burst of photons is detected, and all the photons arrive within a few nanoseconds of each other, then no more arrive until the next burst.   In general this means the light was generated with a laser.  Lasers are a little easier to understand, all the photons are the same, same color (or wavelength), and same phase.  There are continuous lasers which have no pulses, they emit a steady stream of photons.

From a few light years away it is plausible to measure the photon color and determine that a light source is a laser, but unlikely.  For example, amateur astronmers know that a planetary nebula emits OIII lines at 501nm.  All these photons are the same color but they are absolutely not from a laser.  With extremely precise spectrometry it might be possible to determine that a certain set of photons came from a laser.  But there would be a lot of arguing.

However, if the laser is pulsed, and the pulse width is less than 100 nanoseconds, then this signal came from a laser built by an intelligent species.  It's not even necessary to measure the color of the photons.  If they are nanosecond pulses then we are not alone.  All that is needed is that the pulse be bright compared with the background.  For example, point an 8" telescope at a magnitude 6 star.  The telescope collects some number of photons/second, let's say it's a million.  So on average about once every microsecond a photon hits the detector.  Now suddenly a pulse of 5 photons arrives, all within 10 nanoseconds.  Even if that pulse is not repeated it stands out like a beacon, 5 random photons never arrive on top of each other.  A 5 photon pulse means we are not alone.  This works until the average photon rate is around a 100 million per second, so really bright stars will drown out possible optical signals.

With a photomultiplier tube, boxcar integrator, and a decent oscilliscope we amateur astronomers could build our own optical SETI equipment and discover intelligent life.

-------------------------------------------------------------------

**  There is of course always the chance that a shocking new natural phenomenon will be discovered which emits nanosecond pulses.  If you discover that you might have to settle for a Nobel instead of aliens.
