So this video says that the whole visible universe is less than 1000x that of the Planck luminosity.
Thus I declare that the Big Bang was at most 1000-something times bigger than all the stars in the visible universe.

Since energy cannot be created nor destroyed, the Big Bang dissipated into the universe, and therefore the universe is 1000-something times bigger than what we can see.

How's that for being a nerd?

For the lazy, the d00d comes up with this at just after the 7:30 mark in the video.

Not quite my field of expertise, but this reminds me of the controversial dark flow hypothesis (there's a rather interesting video by PBS Space Time about this particular topic), as it also points to vast regions of the broader universe located beyond the cosmological horizon.
