Allan's Perspective is not recommended for the politically correct, or the overly religious! (Some people have opinions, and some have convictions ..., what we offer is Perspective!)

My wife is right, I am anal retentive...., so now I keep a can of WD-40 next to the toilet! (Sometimes I feel like I'm just a bobble-head on the highway of life!)

How to feel small.

We thought you might enjoy a visual approach to knowing what the Universe looks like beyond our galaxy. Well, the SDSS team has outdone themselves, with Miguel Aragon, Mark Subbarao and Alex Szalay teaming up to create the following video of a fly-through of approximately 400,000 galaxies in our Universe, of a journey spanning 1.3 billion light years. This, for reference, is less than 2% of the diameter of the known, observable Universe, but is a large enough sample to give a fair representation of where we live. This is what your Universe looks like; enjoy! (Each spot of light in this video represents an entire Galaxy containing 100 BILLION stars!)
