So beyond even our broadest imagination! I suppose there are also planets out there.
And what is beyond the universe that we can see? Boggles the mind.
That’s the problem with all of these estimates of how many galaxies and planets might be out there - it’s all based on the Universe that we can currently observe, and from which observations we can extrapolate.
We’ll improve in our ability to see as time goes on; but
we’re never going to be able to observe all of it. It will just keep on going and going, beyond our ability to observe, forever.
(That’s the sort of infinitude that God - by His nature - specializes in, and that we will never be able to wrap our little brains around, at least while we’re in this flesh :-)
