In a multi-fold universe, gravity emerges from eIn a multi-fold universe, gravity emerges from entanglement through the multi-fold mechanisms. As a result, gravity-like effects appear in between entangled particles or regions. When applied to astrophysics, these effects are analogous to additional matter within or around galaxies. This way, we recover behaviors that match expected and observed effects when dark matter would be present or missing. No New Physics is introduced in terms of new particles beyond the Standard Model or modifying long range gravity: only the modeling of gravity as emerging from entanglement, in a multi-fold universe.ntanglement through the multi-fold mechanisms.
