modern physics and cosmogony;
a neutron star, a black hole and a recurrent nova (that last I had never heard of before);
the ultimate effects of technology on society;
cosmic life and alien intelligence;
personal interactions and relationships;
language and communication;
the cosmic role of intelligence.
I find Sean M. Brooks' division of Poul Anderson's career into three phases helpful and illuminating:
the Psychotechnic History, an early phase series, was abandoned because science had moved on and the author's views had changed;
the Technic History and the Time Patrol are mature works of the middle period;
The Boat Of A Million Years closes the middle period and opens the later period;
the Harvest of Stars Tetralogy, Starfarers and Genesis are later period future histories addressing new themes and very different from the already mature works of the middle period.
There remains a great deal more to be said about Starfarers.
