Theoretical scenario: if we somehow mange to build a space travel propulsion system using gravity as "propellant" and electric energy to power up this electro-gravity engine and push against gravity, are there any risks of remaining stranded somewhere in the Universe, in an Universal Gravity Hole bubble?

Defining the concept of "Universal Gravity Holes" as lack of gravity, that is, a location in space where all gravity vectors from any direction perfectly cancel each other, are there such places in Universe? What kind of space would qualify to fit this definition? Can we expect atomic size, macroscopic size, or galactic size places that would fit this definition? Seems to me, the concept of "absolute zero gravity" is absolutely real, and I do not talk about "micro gravity" or "artificial zero gravity". If one considers gravity to be a vector, then the whole Universe is filled with an infinity of "absolute zero gravity points", where the absolute reference is the Universe itself, and the total universal gravity strength is zero. Here is the concept:

  • There is an infinity of relatively isolated pairs of celestial bodies in our Universe, close enough to be considered "insulated" from other celestial bodies
  • Each pair of "insulated" celestial bodies has at least one point with a Local Zero Gravity vector
  • Any other remote celestial body in the Universe has a very weak influence in terms of gravity
  • Assuming the gravity of the rest of the Universe is a vector, then the whole Universe around the two celestial bodies acts trough a vector, from one remote point
  • Slightly moving around any Local Zero Gravity point will reach an absolute universal zero gravity point

    $\begingroup$ Lagrange points do not work that way. The gravity of the two bodies does not cancel out at any of the five Lagrange points; Instead the gravitational vectors add so that the net gravitation at the Lagrange point is what is needed to allow a third body to orbit the center of mass at a period equal to the period of the satellite. $\endgroup$ – notovny Jul 22 at 3:00

    $\begingroup$ I voted to close for needing clarity or details, and that was being nice. $\endgroup$ – David Hammen Jul 22 at 4:09
