Quantum cosmology with final states can explain the accelerated expansion of the universe
Teleology is the idea that some processes in nature are directed toward a goal or an end. Today, it is commonly asserted that teleology is a remnant of antiquated ways of thinking about causation, and that it is not compatible ...
Physicists uncover a metallic altermagnet with d-wave spin splitting at room temperature
For many years, physics studies focused on two main types of magnetism, namely ferromagnetism and antiferromagnetism. The first type entails the alignment of electron spins in the same direction, while the latter entails ...
