re: Questions!
Last week at Paris, one of the conferences was about what happened the past 20 years (the City of Science was opened in 1986)....
The same basic questions were asked at the time (as they are today) and there are still no answers! (Is there life out there, are we alone?)..
Actually, it becomes more ,and more mysterious: the universe is made of 95% of dark energy and dark matter..and we don't even know what they are....
So what matters are not the answers (because they imply certainties and that is dangerous) but the questions and the search.
