Dynamic black holes may obey Hawking-style thermodynamics with an alternative entropy meas

Of the known things in the universe, black holes are among the most extreme. They pack huge amounts of mass densely into a small area, producing gravity that is so strong that even light cannot escape. To describe their properties, physicists have relied on complex equations from

MOF thin films reveal hidden dense packing, challenging decades of porous assumptions

Due to their high porosity, metal-organic frameworks (MOFs) are regarded as promising materials for innovative applications, which is why the Nobel Prize in Chemistry was awarded in 2025 for their discovery. They are used, for example, to store gases, to capture CO2 and for the t
