So, looking at the point of something coming from nothing, so instead of that, the beginning of the universe, it's now almost universally described as a period of incredible expansion at any fraction of time. So that's referred to as cosmic inflation, which differs from a singularity that sounds almost like you're splitting hairs. The singularity itself, when you look at it as the classical description of the singularity where the universe comes from, it contains all the matter and time it takes. So, singularity, you can think of a singularity as a black hole, you can think of a singularity as what they thought of as a point in which the universe began, but singularity, it can be described as a state of probable impossibility where physics and math breaks down, which we would think of as like the heart of a black hole. However, in terms of space, scientists are likely talking about infinite density, but not infinitesimal size. You could have a singularity extend across the entirety of space. A singularity should, in most cases, be thought of as a phenomenon of time and not a specific place in space. You could have a huge amount of density, an incredible amount of density somewhere, but it's not located at any particular place in space. So, the Big Bang singularity could be at the cosmos past, but not in a particular place and not at a single point. But a large singularity doesn't sort of jive well with the cosmic microwave background, because the cosmic background is almost flawless, it's actually too perfect, and the light from it is extremely uniform.
