Supernovas are exploding stars in the universe. They are so bright that these stars can indeed be seen throughout most of the universe. They serve as distance markers and track the speed at which the universe expands. Supernova observations have shown an acceleration of the expansion, where this wasn’t expected leading to unknown territories: forces that are not incorporated in any theory up till 2000.
Visualizing the exploding stars seems far away from our body and thus not very connected to garments. But these explosions is also quite “related” if we realize that all the atoms in our body are only made in these extreme exploding stars. We could not have been around if the supernova’s were not dispersing these atoms in the interstellar medium.
We have made a crude visualization of a few of these observations. The flashes are shown on a garment which shows the whole sky. This image is the Microwave background radiation printed on a t-shirt. The oval shape is a special projection called the Mollweide projection.
The Microwave background radiation is at the other end of time in the universe, on the other hand it represents the distribution of mass which leads to galaxies and stars and ultimately to exploding stars.
This picture is a Python Image in Mollweide projection of supernova observations of the first half of 2014: (the numbers are referring to one of the 5 led pannels). (Hopefully all the transformations are done in the right way 🙂
Because a t-shirt is not a screen we had to divide the sky in 5 parts, and if an observation is in these huge parts a led-pannel flashes. The visualization is speeded up: one day has become one second.
Here you can see the action.
In principle the idea was to really have a “live” connection to the universe using a wireless connection from a computer which checks the html page where astronomers put the observations of these exploding stars. For an exhibition in a space with a poor internet connection we have put the data in the script of the microcontroller.
