Fundamental Questions
This is a list of fundamental questions. A resolution to a question is either a satisfactory answer or a conclusion that the question is ill-posed or ambiguous.
| Question | Category | Level | Comments |
|---|---|---|---|
| Why is there something rather than nothing? | Philosophy | Confident | THE fundamental question. Requires a definition of nothing, something, existence and reality. |
| What exists? | Philosophy | Confident | Alternative formulations: 1. What is the nature of reality? 2. What is real? 3. What is fundamental? |
| Does a God exist? | Philosophy | Tentative | Related: If yes, what are God’s characteristics? |
| How did our universe begin? | Physics | Guess | |
| Is there an ultimate causal origin? | Physics | Confident | |
| What is the meaning of the universe? | Philosophy | Confident | Assuming the existence of absolute meaning. |
| Is solipsism correct? | Philosophy | Guess | |
| Are we in a simulation? | Philosophy / Physics | Tentative | Related questions: 1. Is perceived reality an illusion? |
| Does an absolute reality exist? | Philosophy | Confident | |
| What is the role of the observer with respect to reality? | Philosophy | Tentative | |
| Are space and time fundamental? | Physics | Tentative | Related questions: 1. Are space and time emergent? 2. What is the ultimate nature of time? |
For every question I state my personal level of confidence to a resolution. The level should tend to go up with time, but may go down as new findings come in. These are the levels:
-
Certain: I obtained a well articulated resolution, far superior to competing alternatives resolutions, in the form of a proof or similar. For some questions, e.g. some philosophical questions with no hope of entering into the realm of physics, this level cannot be reached even in principle.
-
Confident: I obtained a well articulated resolution, superior to competing alternatives resolutions.
-
Tentative: I singled out a resolution superior to competing alternatives resolutions, but the margin is very small or the resolution not well articulated.
-
Guess: I reduced the possible resolutions to 2 or more options, but I have no clue which one is correct. I have a favoured guess, mainly based on intuition and heuristics.
-
No Clue: No known resolution seems viable or I have no intuition about a random guess. Often due to lack of enough research in the question.
Achieving a Certain level on all the questions above is my life goal. Next best thing is a stable and robust Confident level on all the above.
Great Questions
This second table is about incredibly fascinating questions that do not make my personal cut into the fundamental questions table. In any case they are the source of many sleepless nights of investigation. It is possible for a question to be promoted to fundamental or viceversa.
