Abstract:
In a previous paper the author identified four evolutionary levels of technical civilisations (planet dwellers, asteroid dwellers, interstellar travellers, interstellar space dwellers). This classification scheme is extended here with six new levels on the basis of travelling abilities. The new levels are the following: intergalactic travellers, faster-than-light travellers, parallel universe travellers (with four sub-levels within this category). The detectability of the civilisations is analysed and it is connected to the perspectives of the SETI.
