“Why is there anything at all?”

I must admit I’ve been bothered by the fact that we ultimately cannot find a satisfactory answer for why something like existence itself, well, exists. We now know the Big Bang (probably) wasn’t the origin of everything, and that the current stage of the universe we find ourselves in is just the latest stage of an eternally evolving universe that may very well be part of a larger multiverse, but where did that come from?

“Everything must have a cause” according to Leibniz’s “Principle of Sufficient Reason,” and yet all the causes offered up so far, from God to random quantum fluctuations, don’t give a satisfactory answer. It’s been suggested that this ultimate question of metaphysics is the philosophical equivalent of attempting to square the circle, but I cannot find myself accepting that. There has to be some sort of answer, and this is the territory that allows theism (or at the very least deism) to subtly creep back in, the ultimate god of the gaps that may very well never be shaken out of its hiding spot.

The idea that there exists things humanity will never even hope to comprehend is something far more suitable for Lovecraft’s universe than the scientifically enlightened (for a given value of “enlightened”) one we find ourselves in, and the fact this may very well be true is what disturbs me on a fundamental level. I am afraid I cannot give a satisfactory answer to this, and nor can anyone else. I am sorry.


Gravity, what is it? No one knows exactly *what* gravity is. We can predict its behaviors but not much else, because even relativity’s only an incomplete view. We don’t know exactly what the essence of gravity is, nor the answer to other conundrums like why gravity is so weak compared to the other three forces, and to be frank, speculation aside, we may never know the answer to this haunting riddle, the riddle that has haunted scientists since the days of Galileo and Newton, what is gravity?

This video by the excellent as always John Michael Godier elaborates more on this subject: https://www.youtube.com/watch?v=6MA7jLKnQ4c

I highly recommend it.
