Pente - 5 paintings in sequence

The idea behind these paintings was to create an imaginary sculpture, floating and travelling in an endless space. This sequence is depicted in 5 stages across the canvases. During the journey additional panels and rods have been employed plus a bubble which crowns the image of the fourth stage. In the final stage the bubble engulfs all panels and rods which have collapsed within.  Is this the end of the journey?
