A type of matter which is found near other matter. It cannot be observed directly (it is "dark"), but can be noticed as a result of the pull of gravity from the dark matter. Astrophysicists believe that more than half of the Universe could be in the form of dark matter.
The branch of geometry which deals with curved surfaces and spaces. Calculus is used to analyze the shape of these surfaces and spaces. Differential geometry is a key tool used in the study of General Relativity.
The SXS project is a collaborative research effort involving multiple institutions. Our goal is the simulation of black holes and other extreme spacetimes to gain a better understanding of Relativity, and the physics of exotic objects in the distant cosmos.
The SXS project is supported by Canada Research Chairs, CFI, CIfAR, Compute Canada, Max Planck Society, NASA, NSERC, the NSF, Ontario MEDI, the Sherman Fairchild Foundation, and XSEDE.
