What We Research at the Perimeter Institute for Theoretical Physics.

Researchers at PI build on the two great revolutionary advances of 20th century physics – the relativity and quantum theories:

Einstein discovered that space and time are not separate entities, but are different aspects of a single geometrical entity called spacetime, which dynamically twists and warps as it dances with matter and energy. This dance, called gravity, governs the behaviour of the universe on large scales, from the solar system and galaxies to the entire cosmos as a whole.

The fathers of quantum theory, on the other hand, such as Bohr, Heisenberg, and Schrödinger, discovered strange new laws that were eventually seen to govern the behaviour of all matter and forces on very small scales – the atomic and subatomic worlds, with the exception of gravity, whose quantum nature continues to elude physicists.Both are profoundly powerful theories which not only explain, with extraordinary accuracy, many previously puzzling aspects of the universe, but have also successfully predicted a wealth of completely unexpected new phenomena, from black holes and gravitational waves to lasers and quantum teleportation.
