I would like astronomy simulators to allow us to see stars as dishes/dots of
different colors according to their distance: violet the closest star till red
the most distant star of the set. You would also be able to select the size of
them and/or the size would also be according to the distance - the closer ones
would be bigger - you would just say how big you wanted the closest one and
how small the most distant. It would be a very visual way to differentiate
stars distances.
I call this new field of Astronomy research: String Astronomy...
