Deuterated dichloromethane
Deuterated dichloromethane, also known as deuterated methylene chloride, is a chemically modified form of dichloromethane (DCM) where the hydrogen atoms are replaced with deuterium, a stable isotope of hydrogen. The molecular formula of dichloromethane is CH₂Cl₂, and when it is deuterated, the formula becomes CD₂Cl₂.
Deuterated ethanol
Deuterated ethanol, also known as deuterated ethyl alcohol or ethanol-d, is a form of ethanol (C₂H₅OH) where one or more of the hydrogen atoms are replaced with deuterium (²H or D), a stable isotope of hydrogen that contains one proton and one neutron.
Anatoly Dneprov (writer)
Anatoly Dneprov was a Soviet and Russian science fiction writer, known for his contributions to the genre during the mid to late 20th century.

Hubble's law
Hubble's Law is a fundamental concept in cosmology that describes the relationship between the distance to a galaxy and its velocity moving away from us. It states that the farther away a galaxy is, the faster it appears to be receding from us.
Mean motion
Mean motion, in the context of celestial mechanics, refers to the average angular speed at which an orbiting body travels around a primary body, typically expressed in degrees or radians per unit time. It provides a way to quantify how fast an object moves in its orbit, ignoring the gravitational influences that cause variations in speed due to the elliptical nature of most orbits.
