It's thousands of times more likely in my book that there is no actual matter than this blind stab, posed as a joke then coronated, is the origin. Thanks for playing.
The idea that there ever was a singularity is already ruled out by observational evidence. The “primal atom” of the original idea by LeMaitre and the idea of an infinitely hot and sense singularity are both obsolete. The current “Big Bang” usage refers to the initial hot, dense state generated by the inflationary period that preceded it. The inflationary period was a period where no matter and radiation existed; the energy that existed was energy inherent to empty space. This energy, unlike matter and radiation, does not dilute with spatial expansion but remains constant. The result was a period of exponential expansion. Like any exponential growth, this has the property that for some time x, the size will double over that time. So at time 0, the universe would be at some size a, at time x it would be 2a, at time 2x it would be 4a, and so on.
However it is also a property of such growth that if we look at past times, the size of the universe at time -x would be a/2. At -2x it would be a/4 and so forth. The real important conclusion from this is that no matter how far back you go, the size cannot be zero. Therefore no singularity. In modern usage the term “Big Bang” refers to the event when inflation ceased and the energy from inflation was transformed into the dorms we are now familiar with - namely matter and radiation. This would have been a smaller, hotter, and denser state than the current universe, but not a singularity.
If your idea of overthrowing the Big Bang theory is proof that there never was a singularity, then the JW telescope will fail in that regard. That job is already done.
