It is later revealed that thousands of other monoliths exist elsewhere in the Solar System. TMA-2 replicates itself by a form of symmetrical binary fission and exponential growth to create thousands or millions of identical Monoliths in just a matter of days. When they encountered a living world that had features in favor of the evolution of intelligent life, they left behind the monoliths as remote observers that were also capable of taking a variety of actions according to the wishes of their creators. Tycho Monolith, designated TMA-1 (Tycho Magnetic Anomaly One), is a large black crystalline monolith found on Earth's moon in Arthur C. Clarke’s 2001: A Space Odyssey and its film adaption. Dr. Floyd reaches out to touch the monolith. The concept was inspired by Arthur C. Clarke’s 1951 short story, The Sentinel. This Monolith was officially dubbed Tycho Magnetic Anomaly One, or TMA-1.

They also observed Jupiter and its watery moon, Europa.

Their assessment seems to prove true, as subsequently Frank Poole and the other humans land on Europa and attempt to start peaceful relations with the primitive native Europans. In the year 2513, the first Monolith to be encountered by humankind's prehistoric evolutionary predecessors (the ones featured in the first novel) was found in Olduvai Gorge, buried in ancient rock, and was retroactively dubbed "TMA-0". The Monoliths come in several different sizes: TMA-0 and TMA-1 are both about 11 feet long and TMA-2 is two kilometres long on its longest axis, whereas the Monolith on Europa is considerably larger.

human) interference. In two instances, millions of Monoliths are generated for a limited time purpose. Also, the final monolith is described as a transparent crystal that becomes less transparent when active.

In 3001, millions of copies of TMA-2 assemble themselves into two megastructure disks that attempt to block the Sun from Earth and from its colonies in the Jovian system.

Its artificial construction suggests that it was left behind by “monolith aliens”.

The Firstborn were in many ways physically different from human beings, though from another point of view they were fundamentally the same: they were creatures made of "flesh and blood", and hence, like human beings, they were mortal. In the novels (not in the films), the dimensions of the monoliths are in the precise ratio of 1 : 4 : 9 (the squares of the first three positive integers). As described in Clarke's novel, the Firstborn discovered later how to transfer their consciousness onto computers, and thus they became thinking machines. Kubrick approved, but was disappointed with the glassy appearance of the prop on set, leading art director Anthony Masters to suggest making the monolith black. Hackers at Large, 2001. Though the monolith could be approached without incident, anyone who did so found that their fingers skidded across the absolutely frictionless surface, repelled from the monolith by some invisible barrier, making it impossible to actually touch the monolith itself. It was first assumed to be a giant nickel-iron meteorite, but not even that could produce such an intense field. The first Monolith appears at the beginning of the story, set in prehistoric times. It also influences the fictional history of the series, particularly by encouraging humankind to progress with technological development and space travel. This was taken from the 1951 short story "The Sentinel" that the first story was based on. While it is unclear what the composition of the Monoliths is, they clearly have mass, which is about the only observation that can be made. The epilogue to 3001: The Final Odyssey reveals that the Firstborn had been monitoring humanity's final confrontation with the Monoliths in the Sol system, but chose not to intervene.

The existence of this species is only hypothesized by the rest of humanity, but it is obvious because the Monolith was immediately identified as an artifact of non-human origin. The term "Tycho Magnetic Anomaly" is something of a misnomer when referring to "TMA-0" and "TMA-2", since neither of these is found on the Moon (let alone in Tycho Crater) and neither one of them emits any significant magnetic field, as described in the novel 2010: Odyssey Two (the characters in some of the novels refer to this anomalous nomenclature quizzically). Halman mentions that it was damaged by the impact of Mount Zeus, which is discovered to be a single vast diamond, a shard from Jupiter's core that struck Europa's surface some time following Jupiter's transformation. The second, in 3001: The Final Odyssey, are generated to block both the Earth and human-settled Ganymede from their primary star in an attempt to destroy the humans.

However, they are not completely indestructible: TMA-4 has suffered from damage caused by a giant meteorite of solid diamond that collided with Europa in 2061: Odyssey Three. They may be able to assume any size, because in 2010: Odyssey Two, the Star Child, created from the astronaut Dave Bowman, cryptically notes that the Monolith is actually one size – "as large as necessary".

In the movies, all the Monoliths are black, extremely flat, non-reflective rectangular solids. Astronauts find that this magnetic anomaly is caused by an alien Monolith buried about 15 meters below the surface. "After three million years of darkness, TMA-1 greeted the lunar dawn.".

During the Dutch hacker conference HAL, a replica of the monolith was erected. TMA-1 is fashioned to the exact proportions of 1:4:9, and is dated to about four million years old. Therefore, the aliens created increasingly complex automated machines to oversee and carry out their projects over the eons. The response of the characters to their discovery drives the plot of the series. An identical (except in size) object was found later, orbiting Jupiter (on a moon of Saturn in the book, although this was changed to Jupiter in the sequel book, 2010: Odyssey Two). All of that electric power was expended in the one radio signal. (2010 The Year We Make Contact Soundtrack), 02 Ode To The Sun (Intro). It is believed to be watching over the Europans in a manner similar to TMA-0 in the first book.

Both TMA-1 and TMA-2 produce occasional, powerful, directional radio transmissions. 01 Metro Goldwyn Mayer & Prologue. It is nicknamed the Great Wall after the Great Wall of China, due to its horizontal orientation.
