  • How big is the Universe?

    We don't know. We know that it's been around for at least 10 billion years, and the light in our Universe has been traveling since then. Thus, if the "edge" of the Universe exists, it is at least 10 billion light-years away from us. It's possible that the Universe is bigger than that, though — maybe even infinitely large!

Inspiration

Come, you lost Atoms, to your Centre draw,
And be the Eternal Mirror that you saw:
Rays that have wander'd into Darkness wide,
Return and back into your Sun subside.

From Farid al-Din Attar's
twelfth-century masterpiece
The Conference of the Birds

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.
