A “POSITIVE” EVALUATION OF THE FEASIBILITY OF “STAR WARS” CONCEPTS
Author Mark Brake wrote in the Introduction to this 2016 book, “For the better part of two decades, I’ve explored the relationship between space, science, and culture. This book does just that. Through the lens of Star Wars, we see the universe in a new light. Almost on a daily basis science unveils something new, and potentially shocking… In short, the universe is a strange place. Star Wars is a response to this cultural shock---the shock of finding ourselves in an increasingly marginal position in a hostile cosmos. The stories of Star Wars help us come to terms with this new universe unveiled by science. Star Wars works by conveying the taste, the feel, and the human meaning of the findings of science. Star Wars puts the stamp of humanity back onto the universe. It makes human what was once alien.”
He notes, “To maintain its crew’s well-being, a station needs like support systems … However, reduced gravity can also lead to various health problems such as bone and muscle atrophy… Earth’s gravitational attraction is due to its huge mass, but … assuming Death Star I has a diameter of 75 miles and a mass of 134 quadrillion tons… we can work out the gravitational force at its surface… a person weighing approximately seventy kilograms would feel a gravitational pull of about a quarter that of Earth’s. This would be more than the gravity felt on the moon… Another way to produce a gravitational-type force is to spin the craft like a merry-go-round… On a spacecraft, that pinning against the wall would feel similar to the way gravity acts to pin us down. The wall would effectively become our down, and the center of the spin would become our up. Using this idea, engineers have proposed the creation of a giant bicycle wheel habitat… this idea was … featured in ‘2001: A Space Odyssey.’” (Pg. 32-33)
He explains, “[Han Solo claimed that the Millennium Falcon] ‘made the Kessel Run in less than twelve parsecs!’ In case you didn’t know, distance can have many units; one of which is the parsec. A parsec is … equivalent to how far light can travel in 3.26 years, which is nineteen trillion miles. That’s more than five thousand times the distance to Pluto. So Han Solo’s claim is that the Millennium Falcon made the Kessel Run in less than 230 trillion miles… this is 4.5 times further than the brightest star in the sky, Sirius. This is a distance that can only be achieved through hyperspace.” (Pg. 38)
He acknowledges, “We are a very, very long way from interstellar travel. The major problem is how to support life on such extreme journeys… imagine trying to leave the solar system. That being said, we have managed to send something that far. It’s … the Voyager I space probe, launched in 1977, [which] is now more than twenty billion kilometers away (134 times the distance from the Earth to the Sun)… In perspective, if it were heading in the direction of the nearest star, Proxima Centauri, it would still take more than 73,700 years to get there.” (Pg. 46)
Of the emergence of Life on Tatooine, he comments, “It’s evident that Tatooine has oxygen. Otherwise, Luke and his family would not be able to breathe there unaided… However, since there appears to be a serous lack of plant life… Where is the oxygen coming from? Ruling out the possibility of vast colonies of oxygen-producing bacteria existing somewhere on the planet, there has to be another option. It’s possible that the oxygen was produced in the past when Tatooine had a climate that could support a great deal of plant life. It’s been calculated that if photosynthesis suddenly stopped and no more oxygen were released on Earth, it would take … more than thirty-five thousand years to deplete the oxygen through respiration. So we could potentially be seeing Tatooine … after the loss of its main oxygen producers.” (Pg. 96)
About antigravity proposals, he observes, “If we want to defy gravity by hovering, we’re currently limited to technologies such as lighter-than-air crafts, vehicles with ducted fans… rotary wings, or jet propulsion. These technologies only work up to a maximum altitude or ceiling, above which there isn’t enough air pressure for them to function properly. The operational ceiling of repulsorlift technology … [is] meant to work by pushing against a planet’s gravity. So its operational ceiling would be the altitude at which gravity is too weak for the repulsorlift engines to support [Cloud City’s] weight. This antigravity is ubiquitous in the Star Wars universe, but nothing like it exists in the real world… As of right now, though… it looks as if the idea of a floating city just isn’t feasible.” (Pg. 105)
He says of the Force, “The Jedi are an exclusive organization of force-sensitive individuals, but when we eliminate the element of the Force, we see how similar they are to individuals in reality. They represent a hope of achieving something beyond ourselves, whether it’s superhuman powers, or a connection with some entity that’s bigger than us yet within us all. George Lucas said, ‘I put the Force into the movies in order to try to awaken a certain kind of spirituality in young people. More a belief in God than a belief in particular, you know, religious system.” (Pg. 150)
He states, “According to Star Wars canon, a tractor beam works by manipulating gravitational forces to grab objects… Where does modern science stand on this matter? According to Einstein’s theory of relativity, gravity is caused by a warping of space-time due to the presence of matter or energy… a tractor beam … could warp the space-time in front of an object casing the object to fall towards the warped region. The problem is that as far as we currently know, gravity cannot be focused; it operates in every direction from its source… Therefore gravity is possibly not a good solution unless a way can be found to control it and shield it from particular directions.” (Pg. 201-202)
He says of holographs, “In Star Wars the images are fully three-dimensional, allowing the subject to be viewed from every angle. Considering in some cases the holographic unit is sat in front of the viewer, the problem becomes, how do we get the image of the subject from all angles? At the moment we can only speculate on such a technology. When Anakin goes on a rampage in ‘Revenge of the Sith,’ Yoda and Obi-Wan watch the events unfold on a holoprojector… For this to work, the holoprojector would have to use some kind of sensor that can register a subject’s position and features within the particular field of view.” (Pg. 212)
He explains, “The Force incorporates ideas from many cultures such as the Chinese principle of Qi and the Roman Catholic god. The famous Jedi well-wish ‘May the Force be with you’ is an obvious refiguring of the saying ‘The Lord be with you.’ So it’s possible the Force is meant to be something more spiritual than scientific. Perhaps the Force represents an all-powerful and ever-present God, with the miracles of Jesus replaced by the abilities of the Jedi. Despite the possible symbolism, this abstract theory would bring us no closer to knowing what the Force REALLY is. The problem is, at a quick glance, these miracles and tricks appear to have no real mechanism through which they can be reliably understood.” (Pg. 232)
This book will be of keen interest to Star Wars fans who want to explore the feasibility of its fictional ideas.
