Liebling Wins Buchalter Cosmology PrizeBrookville, N.Y. (March 9, 2015) –Dr. Steven Liebling, professor of physics at LIU Post, received the third place Buchalter Cosmology Prize for co-authoring “Simulating the Universe(s): from Cosmic Bubble Collisions to Cosmological Observables with Numerical Relativity,” published in the Journal of Cosmology and Astroparticle Physics.

Building upon the idea that our Universe arose within a particular bubble among many, each representing a separate universe and existing within a larger Multiverse, in “Simulating the Universe(s),” Liebling and his co-authors developed an algorithm and conducted simulations to determine the effects of a cosmic collision between two bubble universes. The hope is that this work leads to observational tests to see if such a collision occurred in our Universe. The research develops fully-relativistic (i.e., obeying Albert Einstein’s theory of general relativity) predictions that could support the theory of eternal inflation (an extension of the Big Bang theory that asserts that some regions of space-time continue to expand exponentially, producing an infinite Multiverse).  

“Experimental cosmology is advancing so rapidly that it's exciting to contribute to theory that can ultimately be tested by actual observations,” said Liebling.

The Buchalter Cosmology Prize seeks to reward new ideas or discoveries that have the potential to produce breakthrough advances in our understanding of the origin, structure, and evolution of the Universe. The panel of judges recognized the work of Liebling and his collaborators as “a significant advance in linking theoretical predictions with potentially observable signatures of bubble universes in a multiverse cosmology.”

An expert in black holes, numerical and computational modeling, and relativity, Liebling co-authored the paper with Dr. Carroll Wainwright of the Santa Cruz Institute for Particle Physics and Department of Physics at the University of California, Santa Cruz; Dr. Matthew Johnson of the Department of Physics and Astronomy at York University and the Perimeter Institute for Theoretical Physics; Dr. Hiranya Peiris of the Department of Physics and Astronomy at University College London; Dr. Anthony Aguirre of the SCIPP and Department of Physics at the University of California, Santa Cruz; and Dr. Luis Lehner of the Perimeter Institute for Theoretical Physics.

“It’s an honor to be recognized with the Buchalter Cosmology Prize and I am very happy for my collaborators,” said Liebling. “It's always nice to know your work is valued.”
