- TL;DR Summary
- The Big Bang theory did not preclude prior big bangs; still so? Must ejecta have traveled along radii from one center? If so, how could they collide later?
I understand that the Big Bang was an explosion from an extremely tiny mass with particles and quanta traveling away into empty space (anything out there at the instant of this bang being too far to hit yet). I also understand that some ejecta from the Big Bang have been colliding since then.
The mental image I have is of a sphere exploding once and so that every particle or quantum travels along a radius from the center of the original sphere. However, that would mean that the particles and quanta, once ejected, could never collide with each other.
But since they do, something's wrong with my mental image. What am I getting wrong? For example, were there multiple explosions over time? By analogy to an unlikely scale, could it be that the original mass was like a basketball that exploded producing golf balls with some golf balls exploding later so that quanta from one golf ball flew into quanta from another golf ball? Multiple explosions separated by time would support multiple centers for the radii of travel.
Or was some precollision travel nonradial? If, with a single-explosion model, not all radii used for travel had to be equidistant from each other, could gravitational effects have differed allowing unequal attraction between traveling particles? If so, do we have any idea what caused the unequal distribution of radii used as travel routes?
Or did the universe have something like a ceiling that some particles or quanta reached or approached with the ceiling-like structure causing them to bounce or otherwise be redirected back into the thus-bounded universe?
Or is the explanation for the collisions something else?
