We investigate a framework for dark matter production based on conversion-driven freeze-out, a mechanism that allows thermalization of dark matter despite very weak interactions. While this scenario ...

Every galaxy is thought to form at the center of a dark matter halo – a region of gravitationally bound matter that extends far beyond the visible boundaries of a galaxy. Stars are formed when gravity ...

A study by Jessica Santiago from National Taiwan University suggests that primordial black holes, which may still exist in the universe today, could be the source of dark matter. These peculiar ...

All galaxies (including our own) are thought to exist inside a giant cosmological structure called a dark matter halo — a cloud-like phenomenon made up of invisible matter that forms a scaffold to the ...

The theory also introduces the G-field, a novel concept that could provide a quantum-based explanation for dark matter. Credit: SciTechDaily.com A new theory links gravity to quantum entropy and ...

Primordial black holes could inhabit the modern-day cosmos, making them responsible for the phenomenon of dark matter ... black holes in a way that normal electrons couldn't.

In the vast expanse of the universe, galaxies form at the core of dark matter halos—gravitationally bound regions extending far beyond a galaxy’s visible boundaries. These halos are key players in ...

This year's Child Abuse Prevention Month emphasizes the importance of supporting parents and caregivers. Prevent Child Abuse Florida offers programs like Circle of Parents and Period of PURPLE ...

This would mean that all the dark matter in the universe emerged when the cosmos was less than a trillionth of a trillionth of a trillionth of a second old, and well before the first normal ...

While dark matter and baryonic matter don't interact or collide in the normal sense, they can interact due to factors like quantum tunneling. These interactions lead to changes in a planet's ...
