Wow. Bleak. Maybe I shouldn’t have watched all five episodes in one afternoon, but I haven’t been this depressed since Dark Knight. What happened to the randy, swashbuckling Captain Jack that we loved?
On the SciNoFi front though, Torchwood gives us the opportunity to revisit the topic of eyeball spy cameras, last seen in an episode of Dollhouse this spring. As Stephen noted in a post at that time, scientists have been working on plugging directly into the brain (in cats at least) to locate and interpret visual processing activity.
Interestingly, the Torchwood contact lenses appeared to be a much more basic technology: essentially small video cameras that could transmit images back to a laptop and also display text messages to the wearer.
Given how far we have to go in understanding the brain, a contact lens camera is probably a more straightforward and only marginally more detectable solution for this kind of surveillance. Eyeball sized cameras are already commercially available.
Welcome back to the Codex Futurius project, this blog’s never-ending quest to explore the ineffable scientific ideas raised by science fiction. In an earlier entry in the Codex, Jill Tarter of SETI talked about whether we and intelligent-alien species X would recognize each other’s transmissions as such. Now Kevin Grazier–JPL physicist, Hollywood sci-fi adviser, and official friend of Science Not Fiction–looks at the next big question: how we could communicate with any aliens we encounter.
My heroes are in a first-contact situation, meeting an alien face-to-face for the first time. How could my heroes and the alien learn to communicate with each other?
Both knowingly and unwittingly, humans have been broadcasting their presence to the Universe since the 1920s—when coherent transmissions in the radio portion of the electromagnetic spectrum became widespread. Our radio and television broadcasts do not stop at the edge of Earth’s atmosphere; rather they propagate into space at the speed of light. While these signals attenuate with distance, they are detectable nevertheless: NASA still regularly communicates with the twin Voyager spacecraft despite the fact that they are over 100 times further from the Sun than Earth and that each of which transmit data to Earth with less power than a common household light bulb. This means that an alien civilization as far away as 58 light-years could potentially be trying to make sense of “Lucy, you’ve got some ‘splainin’ to do!” (There are 105 G-type stars—ones like our own lovable Sol—within this I Love Lucy-sphere.)
Welcome to another juicy installment of the Codex Futurius project, this blog’s never-ending quest to explore the timeless scientific ideas raised by science fiction. This question about what kind of aliens we may eventually run into goes to Rocco Mancinelli of SETI. Thanks to Dr. Mancinelli for the enlightening contribution and to Jennifer Ouellette, the director the NAS’ Science and Entertainment Exchange (SEEx) program, for connecting us with him.
What is the most likely form an alien would take?
Life’s architecture is difficult to predict because it depends on many factors involving the interaction of the environment and life through evolution and natural selection. We can, however, make some generalizations based on the vast number of morphological forms that life takes on earth.
Put two stars of Battlestar Galactica on stage with an artificial intelligence expert and two leading robotics professors…and you suck the sci-fi out of the room and replace it with reality (sort of). The World Science Festival event “Battlestar Galactica: Cyborgs on the Horizon” drew a large crowd at the 92nd Street Y on Friday night, for a discussion of how human brains might soon fuse with computer chips to create real cyborgs.
Moderator Faith Salie introduced the panelists: Nick Bostrom, director of the Future of Humanity Institute at Oxford University; Michael Hogan, also known as Colonel Saul Tigh; Hod Lipson, director of the Computational Synthesis group at Cornell University; Mary McDonnell, a.k.a. President Laura Roslin; and Kevin Warwick, professor of cybernetics at the University of Reading in England.
Salie asked each panelist to define what a cyborg is. Everyone had different answers: Warwick said it’s something that is part human, Lipson said it’s a moving target or a physical device that takes on biological life, and Bostrom said it’s the essence of human intelligence.
Here’s another entry in the Codex Futurius project, this blog’s never-ending quest to explore the timeless scientific ideas raised by science fiction. This question about communicating with aliens goes to Jill Tarter of SETI. Thanks again to Jennifer Ouellette, the director the NAS’ Science and Entertainment Exchange (SEEx) program, for connecting us with Tarter.
Would/will we recognize an alien transmission right away? Is there a chance we could miss such a transmission, or they ours?
We will recognize the sorts of electromagnetic signals for which we have built good matched filters: nanosecond optical laser pulses, narrowband radio continuous wave or pulsed signals. If signals are of some other type (e.g., a modulation scheme with higher dimensionality, or something other than electromagnetic waves) then we will not detect them, except by serendipity as we build new instruments to study our universe in different ways, or by using increasing computational power to look for more complex types of electromagnetic signals.
If signals are transmitted via a technology that we haven’t yet invented, we will miss them until we manage to invent the appropriate technology (remember that we are a very young technology (~100 years) in a very old galaxy (~10 billion years). I suspect we have a lot more to learn.
On this day in 1968, 2001: A Space Odyssey was released (watch the original trailer). Even though not everyone might agree (Phil, I’m looking at you), 2001: A Space Odyssey is one of the greatest science fiction movies of all time, both for it’s ambitious story and its groundbreaking visuals. Even after four decades the special effects are holding their own (mostly — there are a few obvious cardboard cut-outs in orbit), and the movie still sets the bar for its realistic depiction of space hardware, and life in space.
Alas, the year 2001 has come and gone without moon bases, or privately operated orbital shuttles, but we’re getting there — the International Space Station may not have a Hilton, or rotate to provide artificial gravity, but at least it did just get its last major array of solar panels in place. And although PanAm Airways doesn’t exist any more, let alone the Orion III Space Clipper, private spaceflight did take a step forward recently with successful test flights of WhiteKnight Two, the launch vehicle for Virgin Galactic’s SpaceShipTwo private suborbital spacecraft.
2001: A Space Odyssey‘s influence on later science fiction is impossible to underestimate, and the balletic spacecraft scenes set to sweeping classical music, the tarantula-soft tones of HAL 9000, and the ultimate alien artifact, the Monolith, have all become enduring cultural icons in their own right. Still, for those barbarians who find the measured pace of the masterpiece a little slow, check out this awesome one minute version of the movie. In Lego.
Opening today is Monsters vs. Aliens, the latest digitally animated movie from Dreamworks. While you can see it in regular cinemas, Dreamworks is really hoping that people will flock to IMAX theaters to watch MvA in 3D. The movie was produced with the goal of riding the current 3D cinema wave in mind from the beginning.
In many previous “Made For 3D” efforts, this has resulted in a lot of gratuitous and self-conscious “Look Ma – Depth!” activity, with characters carefully moving to face the screen so they can throw an object or thrust a hand at the audience. Mercifully, there’s only one or two such incidents in MvA. For most of the movie, the 3D is in the service of the storytelling, not the other way around. In particular, the 3D is often used as way to easily establish scale—handy in a movie where giant alien robots square off against puny (and not so puny) Earthlings. The movie also has a lushness about its virtual sets, something which I think Dreamwork’s rival, Pixar, has had an edge on, at least until now.
Opening today is the remake of the 1951 science-fiction classic, The Day The Earth Stood Still, starring Keanu Reeves and Jennifer Connelly and directed by Scott Derrickson (who Science Not Fiction interviewed earlier this week). In the original movie, Klaatu came to inform the Earth that the galactic community was Not Happy about the stockpile of nuclear weapons humanity was building up. This time around, it’s the erosion of planetary biodiversity that has our alien neighbors ticked off. It’s actually not an unreasonable motivation — many astrobiologists suspect that bacterial life may be somewhat common in our galaxy; even in our own solar system there are several possible habitats, including Mars and Jupiter’s moon Europa. But they have speculated that more advanced lifeforms are exceedingly rare: consider that for 85 per cent of the 4 billion years life has existed on Earth, no multicellular creatures arose. So the rapid extinction of many species here would be a significant blow to the biodiversity of the entire galaxy, not just the Earth’s.
Sometime in the future, a group of renegade scientists and technologists will take a time machine to now. They're spilling the secrets of tomorrow here at Discover's Science Not Fiction blog.
