Barak Shoshany

Portrait de Barak Shoshany

Area of Research:
Email: bshoshany@perimeterinstitute.ca

My research in simple terms: I use math to try to understand what spacetime is made of, and what it looks like when you zoom in all the way.


"There is a theory which states that if ever anyone discovers exactly how to quantize gravity, the universe will instantly disappear and be replaced by a universe in which quantizing gravity is even harder.

There is another theory which states that this has already happened."

Barak Shoshany is a PhD student in the quantum gravity group at Perimeter Institute, under the supervision of faculty member Laurent Freidel. He graduated from the Perimeter Scholars International program with an MSc in theoretical physics. Before coming to Perimeter Institute he obtained a BSc in mathematics & physics from Tel Aviv University (Israel) and did summer internships at Weizmann Institute (Israel) and CERN (Switzerland).

Research Interests

Barak's research involves one of the oldest and hardest unsolved problems in physics: the quest for a theory of quantum gravity, which is the unification of quantum mechanics and general relativity. Finding the true theory of quantum gravity is crucial for a full understanding of many of the most fundamental concepts in physics such as black holes, the origin of the universe, and spacetime itself. Specifically, Barak is currently working on one of the most promising and elegant candidates for a theory of quantum gravity, called loop quantum gravity.

In addition to research, Barak is also interested in science communication and outreach. He participates in many outreach activities at Perimeter Institute, and in the past has answered more than 1000 math and physics questions on the popular Q&A website Quora.
