Here’s something to give you an idea of the scale of our universe – to the limits of current science.
There’s a link to a “swirly” version at the bottom if you want to have fun with the zoom.
Nassim Haramein observes that we’re right about the middle of the scale. That suggests it’s because we’re the observer. The universe itself is larger than we yet know and is in turn contained within an even larger structure, etc. etc. Such visualizations as this do help us get a sense of it though.
