Local Group is gravitationally bound, in fact, among the largest such objects in our corner of Laniakea. Hence, with the proviso that dark energy/accelerated expansion paradigm won't wander away (of course, there do exist models where expansion itself, not even dark energy alone, counts as an illusory effect), Local Group will stay with us, instead of being torn into shreds by scalar field(s) driving the relentless expansion. Some folks prone to theology like to equate scalar field that permeates the Universe with God (of the gaps). Your mileage may vary. I abstain from judgment (day), but Higgs field that bestows particles (and us humans) with mass looks like a more promising candidate. Again, of course, models may be constructed where Higgs field and dark energy, and through the latter the expansion of the Universe, have something in common, particularly if early dark energy could be produced with a dark Higgs field trapped at the origin.

However, recent data seem to support even more interesting hypothesis, about dark energy weakening in time.

I could recommend to you a couple of my own reviews on such topics, however, I write pop sci essays mainly in Russian, so perhaps they are unhelpful for you. Still, one random example. Or another one.
