Physicist Carlo Rovelli's new book argues that modern physics—relativity and quantum mechanics—reveals we cannot achieve an ultimate, objective understanding of reality independent of observation. Instead, Rovelli proposes that all properties are relational, existing only in connection to other things, fundamentally rejecting the notion that physics can exhaust what can be known about the world.
Paul Dirac examines how mathematics and physics are fundamentally interconnected, tracing the evolution from Newtonian mechanistic physics through relativity theory. He argues that while the principle of mathematical simplicity guided classical physics, Einstein's relativity demonstrated that deeper mathematical beauty and elegance—rather than surface simplicity—characterize the universe's fundamental laws.
Scientists from Nagoya University developed a method to detect hidden matter around black holes by analyzing gravitational waves produced when black holes merge. The study shows that hidden matter affects the frequency and fade-out speed of ringdown waves differently, potentially revealing whether black holes possess extra structure beyond mass and spin predicted by Einstein's theory.
