Lex Fridman (https://en.wikipedia.org/wiki/Lex_Fridman), the interviewer, is an interesting character.
But Lord Martin Rees (https://en.wikipedia.org/wiki/Martin_Rees) has a brain the size of a galaxy. When you move the cursor to the foot of the YouTube window you can see that the progress meter is divided up into segments, each with a title of what was the subject of that segment. So you can immediately go to a segment that you know will interest you.
I chose to listen to it all. Then I went back to 'Vast Universe', let it run through that and the following two segments 'Alien Life' and 'Space Exploration'.
