Instead of remaining parallel as we move through space in the arrow of time, we get closer to other mass because our paths bend, our clocks running at slightly different beats.
But it wasn't really an explosion, it was more like a spontaneous, insane inflation that found itself suddenly huge and empty, only after it was through with that particular stage did it zap itself full of energy and matter everywhere all at once. Then it continued growing in volume and thinning out via regular ol' relativistic expansion.
EDIT: looking a little bit closer, there's the thing about zapping all over itself after Inflation, it was almost perfectly half-and-half matter/antimatter, which then proceeded to join and annihilate into pure energy, but for some reason probably related to the Weak Force, just a little bit more matter was created than antimatter.
And that's what we are and see today, 1 part out of every 8 million-and-one.
For every 4,000,000 parts antimatter, there were 4,000,001 parts matter, only that 1 left over particle of matter, multiplied a bazillion times.
That's just a whole other level of amazing than just saying "an explosion".
"Before we bone, I must tell you... I ate radishes earlier. Perhaps you should, too."
And that's how you get on equal footing before jumping into the sack.
Was it some sort of blind hookup Tinder-like, and the "password" was a real, actual piece of cheese?
Like with spy craft, "I'll be at the plaza at 10pm, sitting on the bench in front of the fountain. I will be wearing a Gary Coleman "OBEY" t-shirt and carrying a dark green backpack. You will ask me for a piece of cheese".
A steep so slope, it keep you woke!
Seriously, don't drive down this thing in your semi-truck tired, don't even think about going down that waterpark slide unless you're well rested when you get there.
Imagine this spot being your best alternative as a civil engineer, that's one helluva mountain range. What's this, like a pass between the Karakoram or something? Somewhere in the Andes?
You could even overdo it, smothering that triangle with clingy affection, as some sort of rare "sacred and perfect" thing, focusing only on some limited types of symmetries... the skin-deep ones.
More specifically - this is the most Helena Bonham Carter in a Tim Burton movie... etc
