Can We Build a Planet From SCRATCH?

Formation of planet

By SunnyPublished about a month ago 3 min read

Although human activity has not been comparable to a giant meteor impact, our planet Earth will not endure indefinitely. Consequently, we must consider our options as a species in the event of such an occurrence. The most logical course of action would be to establish colonies in other parts of the universe. However, space travel presents significant challenges, and it remains uncertain whether reaching another solar system within a reasonable timeframe is feasible.

Let us consider the possibility of constructing colossal, artificial, planet-sized objects, often depicted in science fiction, such as the Death Star from Star Wars, the planet-building facility in Hitchhiker’s Guide to the Galaxy, or even larger structures like a Dyson Sphere. The civilizations capable of creating such marvels would undoubtedly possess an extraordinarily advanced level of technological prowess. However, it is essential to clarify the scope of our inquiry. Are we referring to an exact replica of a planet like Earth, or a space station of comparable dimensions?

The construction of a space station the size of a small moon or planet presents significant challenges. A moon-sized station would require a precise combination of elements and mass, while a planet-sized station would necessitate substantial engineering efforts. The Death Star, a well-known planet-sized space station from science fiction, would require materials weighing approximately one quadrillion tons for its construction, which is roughly one millionth of the Earth’s weight.

The task of supplying all the material for a moon-sized space station is currently beyond our technological capabilities. For instance, Earth produces approximately 1.5 billion tons of steel annually, which means it would take over 800,000 years to produce enough steel for such a project. Furthermore, the estimated cost of such an endeavor is approximately 852 quadrillion dollars, excluding the logistical challenges of transporting the materials into space. However, assuming these obstacles could be overcome, the actual construction of the space station would be relatively straightforward, as robots could be employed to complete most of the work in the low gravity environment of the moon.

It Is feasible to transport all the required materials into space, although it would be a time-consuming process. Alternatively, we could explore the possibility of extracting materials from asteroids already present in space. Several companies are currently investigating the viability of this approach, and if successful, it could significantly reduce the cost of constructing structures in outer space. Furthermore, it is uncertain whether steel possesses sufficient strength for our purposes, necessitating the potential development of artificial gravity.

Indeed, there are various approaches to constructing a space station, one of which involves rotating the station to generate artificial gravity. This force, if harnessed effectively, could potentially exert enough pressure to deform steel. Consequently, some researchers propose utilizing a carbon-based material derived from asteroids as a more suitable material for this purpose. However, despite the challenges associated with constructing a structure of such magnitude, creating an actual planet poses a significantly greater challenge. Considering that the Earth has been in existence for approximately 4.5 billion years, replicating its conditions presents a formidable task. Nevertheless, it may not be necessary to precisely replicate the Earth to achieve similar conditions. For instance, since gravity is directly proportional to mass, it is possible to construct a structure with one-tenth of the Earth’s mass and shape it to the size of our moon to obtain a comparable gravitational effect. Given the abundance of rocks and debris in space, this approach appears feasible.

Indeed, our planet is the result of the accumulation of sufficient matter. Consequently, if we were able to develop technology capable of replicating this process, it would represent a significant step forward. Some have proposed constructing a fusion facility in proximity to the Sun, which could potentially generate the heavier elements required. These dense metals could then be layered and allowed to cool, forming a stable structure. However, this process would necessitate tens of thousands of years to complete, posing a significant challenge.

From a purely technical standpoint, terraforming an already-formed planet is significantly more feasible than starting from scratch. Nuclear detonations could potentially warm Mars’ atmosphere, while an artificial magnetic field could be created to deflect solar winds, allowing the atmosphere to thicken and the temperature to rise by approximately 7 degrees Fahrenheit.

The concept of constructing a new planet is intriguing, but it currently exceeds our technological capabilities. While the idea of mining asteroids and utilizing robots for assistance is feasible, the realization of such a project would be monumental.
In essence, it is considerably more feasible to examine our neighboring planets and devise a strategy to modify their environments in order to make them less inhospitable. This strategy presents the most probable path for us to discover a habitable location beyond Earth.
