Primordial deuterium abundance

The primordial deuterium abundance is the deuterium-to-hydrogen ratio made by Big Bang nucleosynthesis in the universe's first minutes and preserved in gas that has never passed through stars.

Primordial dwarfism

Primordial dwarfism: group of rare genetic disorders (Seckel, MOPD I/II/III, Meier-Gorlin, Silver-Russell) with prenatal-onset extreme growth failure; MOPDII, the most common form, is caused by PCNT mutations.

Primordial germ cell

Primordial germ cells (PGCs) are embryonic precursors of sperm and eggs, specified by germ plasm inheritance or induction, migrating to the gonad, and undergoing genome-wide epigenetic reprogramming.

Primordial gravitational waves

Primordial gravitational waves are ripples in spacetime generated during inflation, leaving a B-mode imprint in the cosmic microwave background polarization that experiments search for today.

Primordial magnetic fields

Primordial magnetic fields are magnetic fields generated in the early universe, during inflation or cosmological phase transitions. None has been directly detected; they are constrained through the cosmic microwave background, nucleosynthesis, and gamma-ray observations.

Primordial nuclide

A primordial nuclide, often called a primordial isotope, is a nuclide that existed on Earth when the planet formed, formed by nucleosynthesis before the solar system condensed.

Primordial power spectrum

The primordial power spectrum describes the amplitude of density and curvature fluctuations in the very early Universe as a function of scale, seeding CMB anisotropies and galaxy distribution.
