Clearly, we exist, as do the stars and galaxies we see, so something must have created more matter than antimatter, making the Universe we know possible. But how did it happen?

But before we get to that, let’s take a look at how “material” – physical matter – first came about. If we are aiming to explain the origins of stable matter made of atoms or molecules, there was certainly none of that around at the Big Bang– nor for hundreds of thousands of years afterwards. We do in fact have a pretty detailed understanding of ho...
To truly answer the question of how something could arise from nothing, we would need to explain the quantum state of the entire universe at the beginning of the Planck epoch. All attempts to do this remain highly speculative. Some of them appeal to supernatural forces like a designer. But other candidate explanations remain within the realm of phy...
Conformal cyclic cosmology offers some detailed, albeit speculative, answers to the question of where our Big Bang came from. But even if Penrose’s vision is vindicated by the future progress of cosmology, we might think that we still wouldn’t have answered a deeper philosophical question – a question about where physical reality itself came from. ...
For a philosopher of science, Penrose’s vision is fascinating. It opens up new possibilities for explaining the Big Bang, taking our explanations beyond ordinary cause and effect. It is therefore a great test case for exploring the different ways physics can explain our world. It deserves more attention from philosophers. For a lover of myth, Penro...
Jan 3, 2022 · How did the whole system of cycles come about? Then we finally end up with the pure question of why there is something rather than nothing – one of the biggest questions of metaphysics.

I formalize "something can come from nothing" as ∃x∄y (x COMES FROM y), or "there is some thing x such that there is no thing y that x comes from. The negation is ∀x∃y (x comes from y). – David H.
