It is sometimes said that the three greatest – and toughest, and most significant – remaining scientific questions are these:
- What caused the Big Bang?
- What is the “Grand Unified Theory” that integrates quantum mechanics and general relativity?
- What is the conscious self?
It’s interesting that the last question is up there with the first two: it’s that difficult and that important to answer. And from a contemplative perspective, including a Buddhist one (our own home ground), the self is often seen as a major source of suffering.
