*Definicija jakosti gravitacijskog polja se matematički može dobiti i na alternativni način uvrštavanjem jedinične mase u drugi [[Newtonovi zakoni gibanja|Newtonov zakon]].
*Ako neko tijelo promijeni položaj u prostoru, jakost njegovog gravitacijskog polja u proizvoljnoj točki prostora će se promijeniti u skladu s tim pomakom tek nakon onoliko vremena koliko je potrebno da svjetlost dođe od tijela do te točke.

Citat teksta o Gravitaciji iz engleske Wikipedije:
"Gravitation, or gravity, is a natural phenomenon by which physical bodies attract with a force proportional to their mass. Gravitation is most familiar as the agent that gives weight to objects with mass and causes them to fall to the ground when dropped. Gravitation causes dispersed matter to coalesce, and coalesced matter to remain intact, thus accounting for the existence of the Earth, the Sun, and most of the macroscopic objects in the universe. (Wikipedia).
...and common, Croatian and English, comment:
The planet Earth and the Sun are connected toward the geocentric theory, what proves version of Calendar and theory of Leap year of the author Boris Špadina.
