From Wikipedia, the free encyclopedia

Spacetime, according to general relativity, is bent by objects with mass, causing time dilation.

Philosophy of physics is the study of the fundamental, philosophical questions underlying modern physics, the study of matter and energy and how they interact. The main questions concern the nature of space and time, atoms and atomism. Also the predictions of cosmology, the interpretation of the results of quantum mechanics, the foundations of statistical mechanics, causality, determinism, and the nature of physical laws. Classically, several of these questions were studied as part of metaphysics (for example, those about causality, determinism, and space and time). Today, the philosophy of physics is very close to the philosophy of science, and is the most active subtopic within it.
