A more lighthearted summary of MiHsC, occasionally veering into a Yorkshire accent:
Inertia means you coast along, no-one ever explained the why,
but when you accelerate, a horizon opens behind you as you fly.
The horizon's like a black hole's, so it gonna be damn hot.
You'll see Unruh-heat, if accelerating, but nowt at all if not.
Heat is waves, and MiHsC theory says: they must fit from you to the horizon
because partial waves would let you see behind Mach's forbidden curtain.
So from behind you, horizonward, there'll be fewer waves impacting
The waves in front'll push you back, just as inertia's long been acting
OK so far, but can MiHsC say why in deep space physics fails?
In that slow realm the waves are as long as Hubble's cosmic scales.
So there MiHsC disallows more waves and inertial mass collapses.
Quite a shock, but maybe welcome if you've 'et too many biscuits.
Galaxies spin so fast the centrifugal force should explode 'em all.
MiHsC reduces this inertial force just right: it's really on the ball.
Cosmic acceleration is predicted since before accelerations disappear,
the Unruh waves grow too long to fit into Hubble's sphere.
Dark matter is like Ptolemy's epicycles on steroids, by computer.
MiHsC works with just a few lines, on a piece of paper.
