• How old is the Universe?

    Current models of the Universe's past, together with observations indicate that the Universe is roughly 14 billion years old. Now, we know that our models aren't exactly correct, but they are pretty close to the correct answer. That means that there is a little wiggle room in this number, but it's pretty nearly right. In fact, astronomers have seen stars that are at least 10 billion years old.

About SXS

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.
