ScienceAlert Article:  The Entire Known Universe, in a Single Image.  Here's What It Looks Like  Created by musician and artist Pablo Carlos Budassi , there is lots more information available in his Blog: Observable Universe Logarithmic Illustration Blog   The entire observable Universe can be featured because the distance scale diminishes exponentially the further you go out from the Earth according to the following scale: This scale is featured on the version of the illustration that features helpful labels: Further information on the logarithmic projection for maps is provided by Philippe Rivière including an interactive sample projection centered on Iceland which can be observed as variables are altered:   The Log-Azimuthal projection   As we look further and further away we also look further and further back in time since light although fast, does take time to travel long distances.   NASA...

Light Invisible

It is very humbling to contemplate the electromagnetic spectrum and the tiny sliver that encompasses the full range of colors we can perceive.   For his Chemistry Lab , Ken Costello considered this to mean that in terms of the full spectrum we are indeed...  "The entire light spectrum (also known as the electromagnetic spectrum) spans light waves that are miles long to waves that are extremely short. The light we see (visible light) only spans about 1.5% of the entire light spectrum. So we would be legally blind considering what we could see." Experiment 7: Light as a Tool To clarify the extent of this blindness, Ken Costello compared full spectrum perception to the color picture of a mountain scene (left) and then removed all but 1.5 percent of the color (right) to emphasize the 1.5 percent of the electromagnetic spectrum that we can actually perceive: Clearly we are missing a lot and it is only by using powerful scientific instruments that w...
