Gravity defined precisely with quarks – squaring the circle to achieve fine description of black hole physics, and understanding the formation of key constellations

Gravity is redefined by drawing on the author’s works and inputting quark physics in a way consistent with it ; it allows to better understand black hole dynamics, black hole eruptions and some constellation patterns in the sky (the Scorpio, Ursa Minor and Ursa Major as well as Cassiopea for instance). The concept of gravitational lensing is rapidly differenciated from black hole eruptions. Some final remarks underline a possible threat for missions to the Moon.
