    Dimensionless numbers, not dependent on any mere mortal, subjective arbitrary unit of measurement like length (meters or yards or cubits - same difference) or time.
    Whether you are on Earth or a planet in Andromeda or a billion light-years away, if you study subatomic structure you WILL bump into the fraction 1/137. Just like you will in geometry with 3.1416.

    A bullet fired from a gun goes more or less at Mach 1, correct?
    It’s thirteen years to the sun at the speed of a bullet?

    Spacecraft towards Mercury, or the Parker Solar Probe go much faster than that, take a few years to make it there, but they are doing so picking up speed in flybys of first Earth, then Venus, then Mercury, in several, ever tighter orbits.

    It’s both fun and illuminating to try and visualize these things in new ways. In this case, from the viewpoint of a bullet.

    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”.

    It actually could be part of the background urban texture in a cyberpunk world. Like Jollybee or Chow King, Taco Chief could be a large Asia-based chain, peddling… I mean serving… generic tex-mex in places like Bangkok, Kuala Lumpur, Brunei, Jakarta and Manila, in the year 2050.

    Yeah, but what about “Groove Is In The Heart”, then?

    Also: it’s “Pump The Jam”, not “Pump Up The Jam”.

    EDIT: Well here I stand, corrected. I can’t believe my mind’s been Mandela-effected for thirty years, I’ve always thought it was just “Pump The Jam”.
