Hard to wrap my mind around this one. Anyone have any good analogies that fit?

I guess like some fireworks where you’re watching the trail of the rocket then suddenly the sky lights up with hundreds of bursts.
I would love to hear about the speed of causality? Or was everything created (and I mean everything) created on the figurative head of a needle and that was the actual start. Then a totally separate event was the explosion that create time and space. It could have happened 10 trillion years later less than a planck time unit? But all the matter and energy was compacted into oneness.

They explain it pretty well, basically the “everywhere” is all contained in the “singular point”, like a stack of cards which then you throw up in the air, everything everything was one “thing”, the stack, and suddenly there’s a bunch of things moving away from each other. the problem is that this analogy involves something “breaking” or separating, which wasn’t the case with the big bang
Before the Big Bang, in whatever way the concept of “before” makes sense, reality existed in a state of maximum entropy, not unlike what it will be after its heat death. Energy existed, but was maximally spread out and uniform: there were no differences anywhere, and so nothing could happen, not even matter. Time and space had no meaning.
Then, for reasons we don’t understand, entropy suddenly dropped in a region of this space-less space. Energy very suddenly concentrated in one very small part of reality. This was not the Big Bang: this was the condition that gave rise to it. Now that there was a difference in energies between one part of reality and another part, things could happen. Time and space took on meaning.
In the next instant -actually the *first* instant- that part of reality began the long, slow process of cooling down to rejoin the rest of reality. *This* is what we who are inside this universe perceive as the Big Bang. Despite the name, it wasn’t an explosion -it was the universe beginning to cool- and that’s the key to understanding why it happened everywhere at once.
Just to answer this question and another, very similar, question at the same time: Imagine two gigantic cakes are catapulted toward each other.
It may be more than two cakes, but the metaphor still works.
(And where the cakes came from matters, as well as the catapults, but those are questions for a different day.)
So, you have two cakes: One chocolate, and one yellow (Because other flavors suck. Yeah, I said it.)
One cake is some of the ingredients of our universe. The other cake is the other ingredients of our universe. But they haven’t mixed yet, so our universe isn’t actually yet a thing.
So they fly toward each other at a crazy speed, because of being thrown by the catapults, and they slam into each other. There isn’t really a single point of contact. They both kinda just mush into each other and explode in all directions.
Thus, the Big Bang.
And this also explains the ‘What about before?’ question, because Time only existed in one of the cakes. There is no such as ‘Before’ the Big Bang, because Time didn’t even exist in our universe yet, because the universe, itself, didn’t exist until after the Big Bang.
The big bang is obviously not possible and it’s only used because we have no idea what the hell happened.
My theory is since everything else observable is cyclical that the big bang was merely the inversion of whatever existed prior.
I subscribe to the idea that inside blackholes is another universe. Composed of whatever has been absorbed into the blackhole and shot out the other side. Since everything observable is consumed by a blackhole it makes sense the other side is another replication of our existing universe materially.
Making us even smaller than we even imagined inside our single universe.
Just like a field of flowers blooms all at once, because the season is just right – space bloomed.
And just like in a very big field, where you can spin and see flowers as far as the eye can see, we can spin and see space as far as the telescope can see.
Maybe there is an edge, but so far we haven’t seen it. All we see are flowers.
None of these analogies helped me understand. Can someone explain like I’m four instead?
