Dark Energy Turns On When Galaxies Are Born ⚡ экспресс
A new mechanism has been proposed linking dark energy to the formation of large-scale structures. As dark matter condenses into halos (clouds), it shifts the equilibrium of a scalar field, locally generating vacuum energy. If the field is massive enough, its influence is confined within the halo, but when averaged over the universe, uniform dark energy emerges, dominating around redshift z~1. The model agrees well with the latest DESI data. Each halo acts as a microscopic generator of cosmic acceleration.
The universe is expanding faster and faster, and scientists blame it on dark energy. Its origin is explained in a new way: dark energy isn't eternal, but appears only after dark matter clumps together into lumps — future galaxies.
The mechanism works like a pump that turns on when pressure drops. Inside the clumps of dark matter, a repulsive force is born, acting as dark energy. The more structures form, the stronger this effect — each galaxy becomes a tiny generator, accelerating the cosmos.
Calculations show: dark energy began to dominate about 7 billion years ago, when the universe had accumulated enough large clumps. This matches recent observations. The most surprising thing: if dark energy had been constant from the beginning of time, it would have prevented the formation of galaxies. In this model, it "politely" waited until structures emerged, and only then switched on accelerated expansion.
