AGAINST GRAVITROPISM: ART AND THE JOYS OF LEVITATION
Eduardo Kac
"Gravitropism" means growth in response to gravity [1]. I use the term gravitropism in art beyond its biological origin, to underscore the fact that gravity plays a fundamental role in the forms and events we are able to create on Earth, and that forms and events created in zero gravity to be experienced in the same environment might be radically different. I first wrote about gravitropic forms and events in 1987, while creating and articulating the theory of a new poetic language produced out of light, with protean linguistic events floating and changing in space, freed from material and gravitational constraints. In my original text I stated: "As we experience massless optical volumes -- focused luminous vibrations suspended in the air -- "gravitropism" (form conditioned by gravity) makes way for "antigravitropism" (creation of new forms not conditioned by gravity), freeing the mind from the clichés of the physical world and challenging the imagination". [2] I coined the word "antigravitropism" to retain the affirmative quality of negating or neutralizing gravity.
The powerful gesture of defying gravity in art can be traced back to innovative early twentieth-century sculptors, such as Calder and Moholy-Nagy. While the first reduced the support of massive structures to a single suspended point with his "Mobiles", the second went as far as experimenting directly with levitation, with absolutely no physical support whatsoever. In his seminal book "Vision in Motion", published posthumously in 1947, Moholy-Nagy appears levitating a chisel with compressed air. The photograph is striking: we see Moholy-Nagy's profile and before him the object suspended in the air with no apparent means of support. In previous books Moholy-Nagy articulated notions about the evolution of sculptural form, suggesting that the virtual volume--volume created optically by the accelerated motion of an object--was a new possibility for sculpture. In his film "Design Workshops" (1946), he presented a sequence, less than a minute long, in which colored ping pong balls float in an air jet. As an artist crossing many discipline boundaries, Moholy-Nagy also considered that in the future the neutralization of gravity could be a useful tool in design. It was not until the 1960s that several of this visionary's ideas would find currency. Hans Haacke's sculpture "Sphere in Oblique Air-Jet" (1967), presents the viewer with precisely what its title indicates: a buoyant balloon that stably hovers in space. The sculpture accomplishes this feat through what is known as Bernoulli's principle, according to which a stream of air (or fluid) has lower pressure than stationary air (or fluid). On a practical level, this means that moving air can create aerodynamic lift.
Although the Hungarian constructivist did not explore this notion in his own sculptures, levitation and the conquest of space attracted the attention of artists working in the 1950s. Lucio Fontana's Spatialist movement, for example, made direct references to space. In 1951 he clearly stated: "Man's real conquest of space is his detachment from the earth". Aaron Siskind's 1950s series of photographs "Terrors and Pleasures of Levitation" present the viewer with contorted and airborne human bodies. These compelling images, which evoke humankind's mythical dream of flying, look as though they could be right out of an astronaut training program.
While in all three cases it is really the metaphor of space and levitation that is brought to the fore, the use of magnetism to suspend forms in space became the key element in the innovative work of the Greek kinetic artist Takis. In 1938 Gyorgy Kepes produced a series of photographs and photograms in which he experimented with the visual properties of magnets and iron filings, but it was Takis who, in 1959, introduced the aesthetic of sculptural magnetic levitation with his elegant "Télésculpture". The sculpture is composed of three small conical metal pieces that are attached, through thin wires, to three nails. The three conical pieces are suspended above an irregular plane and levitate in front of a magnet. This was the seed of a complex body of work through which this magician of levitation has investigated the expressive power of invisible forces. In September of 1959, the Moon was first visited by the Soviet spacecraft Lunik 2. As the first probe to impact the Moon, Lunik 2 made evident that human displacement in space was on the horizon. Fascinated by the implications of this idea, Takis realized an event in 1960 at the Iris Clert Gallery, in
One peculiar approach to the suspension of (ephemeral) forms in space is the use of vaporous substances through a technique known as Skywriting, which consists in the writing or drawing formed in the sky by smoke or another gaseous element released from an airplane, usually at approximately 10,000 feet. In the late 1960s and early seventies, artists such as James Turrel, Sam Francis, and Marinus Boezem started to employ skywriting as a medium. Poet David Antin created skypoems over
The artistic use of skywriting further extended the aerial performances set forth in Futurist manifestoes. In addition to the writings of Futurism's founder, Filippo Tommaso Marinetti, including his proposals of "aeropainting" (1929) and "aeropoetry" (1931), of particular relevance is the 1919 manifesto "Futurist Aerial Theatre", by Fedele Azari, in which he wrote: "I HAVE MYSELF PERFORMED, IN 1918, MANY EXPRESSIVE FLIGHTS AND EXAMPLES OF ELEMENTARY AERIAL THEATRE OVER THE CAMP OF BUSTO ARSIZIO. I perceived that it was easy for the spectators to follow all the nuances of the aviator's states of mind, given the absolute identification between the pilot and his airplane, which becomes like an extension of his body: his bones, tendons, muscles, and nerves extend into longerons and metallic wires." Another significant, albeit little known antecedent, is the "Dimensionist Manifesto", published in 1936 by the Hungarian poet Károly (aka Charles) Sirato and signed by Arp, Delaunay, Duchamp, Kandinsky, Moholy-Nagy, and Picabia, among others. The "Dimensionist Manifesto" was published in
Bruscky's proposal explored a scale greater than the Land Art or the Earthworks typical of the period, since his vision of an artificial aurora borealis would reach millions at once, who would see the work simply by looking up at the sky. By contrast, works that manipulate magnetism or electromagnetism often have a smaller, more intimate scale. If Takis' work has a forceful and raw power that emanates from his unadorned handling of materials such as iron and steel, quite different are the levitation projects by the American artist Thomas Shannon.
Many developments in twentieth-century art led to a radical reduction in the use of physical matter to form sculptural volume and to support or present this volume in space. From Gabo's constructions (1919/20) to
The inevitable conclusion is that zero gravity is the next frontier. Artworks have been taken aboard spacecrafts since 1969, when "The Moon Museum", a small ceramic tile with drawings by artists such as Robert Rauschenberg and Andy Warhol, was carried to the Moon aboard a Saturn V rocket on Apollo 12. A significant development was the permanent installation of a sculpture by artist Paul van Hoeydonck (Antwerp, b. 1925) on the surface of the Moon in 1971, also carried on a Saturn V rocket on Apollo 15. Entitled "Fallen Astronaut" (aluminum, 8.5 cm long), the work was placed at the Hadley-Apennine landing site by American astronauts Dave Scott and Jim Irwin (Apollo 15). Next to the sculpture, inserted in the lunar soil is a commemorative plaque, homage to astronauts and cosmonauts who lost their lives in the course of space exploration. In 1989 Lowry Burgess flew objects on the Shuttle as part of a conceptual artwork entitled "Boundless Cubic Lunar Aperture". These works are significant steps towards an art that engages outer space materially, but they were not created in outer space or conceived specifically to investigate the new possibilities of art in true weightlessness. The first works to do so are the sculpture "S.P.A.C.E.", created outside the Earth by American artist Joseph McShane in 1984 and the sculpture "The Cosmic Dancer", created in 1993 by Arthur Woods, an American artist living in
McShane's work was launched into space on October 5, 1984 aboard the U.S. Space Shuttle Challenger. McShane’s piece was produced with the vacuum of space and the conditions of zero gravity and returned to Earth in its altered state. A sphere with a valve and earth atmosphere within was opened once in orbit. The vacuum of space evacuated the sphere, the valve was closed, and the vacuum of space was then contained within. For McShane, the artwork is not the glass object per se, but the containment of outer space within, the potential wonder generated by bringing space vacuum to Earth and to close proximity to viewers. The question concerning the reception of space art necessarily involves a reflection on the experience of it in space. The primary viewers for "The Cosmic Dancer" lived with the "terrors and pleasures of levitation" in conditions of zero gravity. A sharp-angled form launched to the Mir Space Station on May 22, 1993, "The Cosmic Dancer" stressed the cultural dimension of space since it created the experience of art integrated into a human environment beyond Earth. The video that documents the project shows the two Russian cosmonauts Alexander Polischuk and Gennadi Mannakov performing (rotating, hovering, flying) with the sculpture in the confines of Mir, where the sculpture was left. The flaming remnants of the Mir space station plunged into the South Pacific on March 23, 2002.

In the case of Arthur Woods, the performance of the cosmonauts complements his project. As one watches the video documentation, one feels that the cosmonauts stand vicariously for all viewers, that is, all those who in the future will have the opportunity to experience space as a social and cultural milieu, and not only as a research lab. Clearly, the performance of the body in an environment devoid of the forces of gravity is aesthetically rich in its own right. This very issue has been the focus of French choreographer Kitsou Dubois's work for over a decade. Since 1991 she has been flying in microgravity parabolic flights and exploring the gestural, kinesthetic and proprioceptive potential of weightless dance. She has flown alone as well as with other dancers. Dubois is unique in her relentless investigation of zero gravity. In addition to continuously pursuing new levitation opportunities, she has published extensively on the subject, obtained a Ph.D. with her research as the topic of the dissertation, and recreated her experiences in theatrical as well as installation works. As a byproduct of her choreographic work, Dubois has also developed a training method for astronauts based on her new protocols for zero gravity dance.
The spectrum of the live arts in space would be incomplete without theater. In 1999 Slovenian director Dragan Zivadinov staged his Noordung Zero Gravity Biomechanical Theater high above the
While Zivadinov conceived of the aircraft as a theatrical set, and Woods employed a space station as an ancillary element in the fulfillment of the antigravitropic potential of his sculpture, the media artist, architect, and designer Doug Michaels proposed in 1987 the design of a rather unique space station cum artwork cum "alternative architecture". A co-founder of Ant Farm design group ('68-'78), Michaels was the co-creator of emblematic works of the period, such as Cadillac Ranch (ten cars planted nose down in 1974 in a wheat field located west of Amarillo, Texas) and Media Burn (a 1975 performance in which Michels drove a Cadillac through a pyramid of television sets on fire). In 1986 he established the Doug Michels Studio to pursue innovative projects in architecture and design. Michaels, who passed away in 2003, developed with his colleagues in 1987 a concept for a spacecraft to host artists and scientists interested in human-dolphins interaction and communication. The project resonated with the pioneering work of John Lilly, a scientist who defended the idea that dolphins have consciousness and intelligence at a time when this fact was not yet scientifically established. As a result of his research, Lilly went on to author books such as "Man and dolphin" (Garden City, N.Y., Doubleday, 1961), "The Mind Of The Dolphin: A Nonhuman Intelligence" (Garden City, N.Y., Doubleday, 1967) and "Communication Between Man and Dolphin: The Possibilities of Talking With Other Species" (New York: Crown Publishers, 1978). On its January-February issue of 1987, the magazine The Futurist featured Michaels's Project Bluestar, an orbiting "think tank in zero gravity" meant to include both humans and dolphins. According to the proposed design, the marine mammals' ultrasonic emissions would be used to program the central computer. This proposal was as much about the vision
In 1993, the same year Woods launched "The Cosmic Dancer", the Chinese artist Niu Bo started "The Zero-Gravity Project", which he first pursued in

Artworks such as discussed above open a new realm of speculative inquiry into the future of art in worlds other than the Earth. While we remain confined to the blue planet, three possibilities open up for art that engages what could be called a "zero gravity sensibility". First, it is clear that the potential for magnetism and electromagnetism in art is far from exhausted. Second, the increasing access to microgravity facilities in
Electromagnetism holds great potential for sculptural levitation. Yet untapped, for example, is a property known as diamagnetism. Diamagnetic materials repel both the north and south poles of a magnet. All materials are weakly diamagnetic, but it is difficult to levitate ordinary objects. However, with a strong magnetic field and strongly diamagnetic materials (such as neodymium magnets and graphite blocks), it is possible to create stable regions for diamagnetic levitation.
Artists seeking to explore levitation beyond magnetism and electromagnetism can investigate advanced techniques presently only found in research laboratories. A high-temperature electrostatic levitator allows the control of heating and levitation independently and, unlike an electromagnetic levitator, does not require that the floating object be a conductor of electric charge. Acoustic levitators enable the suspension of liquids in a state of equilibrium through acoustic radiation force. Also, liquids can be suspended by a gas jet and stabilized by acoustic forces. Superconductor levitators enable objects to float above a magnet in fog of liquid nitrogen. With a laser levitator it is possible to trap gas bubbles in water and create a condition of stable levitation by applying optical radiation pressure of the light beam horizontally and vertically. Atom chips allow for the trapping and manipulation of clouds of atoms, which magnetically levitate above the chip's surface. Portable quantum labs promise to further expand the magnetic control of atom clouds levitating in free space. At last, as levitation touches biology, molecular magnetism is predicated on the application of ordinary but very strong magnetic forces over a regular object. The forces are directed upwards and take advantage of the very weak magnetic response of the object present in the field, enabling the levitation of objects usually not regarded as capable of levitation (such as plastics) and living organisms (plants, insects, small animals -- and conceivably humans, if the field could be made strong enough). The manipulation of the magnetic properties of nanosized objects is also a possibility, which could include macroscopic manifestation of the quantum behavior of these very small objects. These techniques offer a glimpse into what might be possible when life in the international space station becomes more common, when colonization of the Moon goes from science fiction to science fact, and when the space program overcomes what, in the public opinion, is its most exciting challenge: landing human beings on Mars. The creation of new alloys and compounds in zero gravity and the prospect of interplanetary colonization suggest that space exploration is more than a metaphor in art. It is a material and intellectual challenge that must be met.
NOTES
1 - Gravitropism is a Botany term. Roots have positive gravitropism because they grow in the same direction of gravitational forces (i.e. down). Stems on the other hand have negative gravitropism, as they grow against gravity (i.e. up).
