Lorentzian geometry forms the mathematical cornerstone of modern spacetime theory by providing a framework in which the causal structure and metric properties of the universe can be rigorously ...
Physicists from the Eötvös Loránd University (ELTE) have been conducting research on the matter constituting the atomic nucleus, utilizing the world’s three most powerful particle accelerators. Their ...
Describing natural phenomena with geometric language is one of the most important achievements of modern physics. In the context of general relativity, Einstein treats spacetime as a dynamic geometric ...
Higgs meets fifth dimension: A new model suggests the Higgs boson may be a mix with a scalar from a hidden fifth dimension, potentially linking visible matter to dark matter. Spacetime's preserved ...

How Einstein changed our sense of time and space
Einstein’s big shift: He replaced Newton’s pull with curved spacetime, showing gravity as geometry rather than a force. Time isn’t universal: Special and general relativity reveal that motion and ...
Spacetime, the invisible fabric stitching the universe together, could actually be far more complex than previously believed. Long ago, Einstein gave us a set of equations describing how stars and ...
There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...
Spacetime isn’t something that exists; it’s a model for describing how events happen. Treating events as objects creates philosophical confusion and fuels misconceptions, such as time-travel paradoxes ...
