The term protomatter may reference: in programming, a Java logging framework; in cosmology, a theoretical primordial plasma, ylem, in the Big-Bang generation of matter;
Protomatter is a key component of the Genesis Device prototype—an experimental terraformation device introduced in Star Trek II: The Wrath of Khan. Protomatter is presented as an unstable substance that, due to its instability, is considered unethical for usage in scientific research.
Ylem (/ ˈ iː l ɛ m / [1] or / ˈ aɪ l ə m /) [2] [3] is a hypothetical original substance or condensed state of matter, which became subatomic particles and elements as are understood today.
The above definition is not endorsed by the International Astronomical Union, and other working groups may choose to adopt the same or a different definition. The dividing line between a planetesimal and protoplanet is typically framed in terms of the size and the stages of development that the potential planet has already gone through ...
Simple illustration of particles in the solid state – they are closely packed to each other. In a solid, constituent particles (ions, atoms, or molecules) are closely packed together. The forces between particles are so strong that the particles cannot move freely but can only vibrate. As a result, a solid has a stable, definite shape, and a ...
An artist's illustration giving a simple overview of the main regions of a protoplanetary disk, delineated by the soot and frost line, which for example has been observed around the star V883 Orionis. [15] The nebular hypothesis of solar system formation describes how protoplanetary disks are thought to evolve into planetary systems.
A quark (/ k w ɔːr k, k w ɑːr k /) is a type of elementary particle and a fundamental constituent of matter.Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei. [1]
A protoplanet is a large planetary embryo that originated within a protoplanetary disk and has undergone internal melting to produce differentiated interiors.
