Is it possible that a tiny amount of dark energy(much smaller than even the iron core of earth) could lower the gravity on a planet without breaking the planet apart? I mean, dark energy is basically anti-gravity. If our universe did not have much dark energy, the gravity of dark matter would overcome the anti-gravity of dark energy and our universe would go through a Big Crunch and possibly after some time, another Big Bang.
If so than could this allow earth-like planets with larger radii and more mass than earth, possibly even mega-earths(rocky planets above 10 earth masses) to have a reasonable amount of gravity for human colonization while still having a density comparable to that of earth?
I mean, with super-earths and to a higher extent, mega-earths, the only way you could have a similar density to that of earth with a larger mass and radius is for gravity to be higher. If gravity gets too high, the heart would work itself to exhaustion and our bones would more likely break, even with perfect balance. Broken bones can lead to arterial bleeds and untreated arterial bleeds are most often fatal because of the high pressure in the arteries. And if gravity was similar to earth gravity, it would most likely be a gas planet a lot like Saturn.
So basically without dark energy, for a massive planet, there are 2 possibilities.
Could dark energy solve this problem if it was in the core of the planet? Could it make it so that it has a density comparable to earth(so it is rocky) without the Jovian gravity and instead with a similar gravity to that of earth despite its higher mass and radius?
