sorry if this is a horrible surprise
but there’s really no such thing as SUNRISE
objects in space have no up or down
they just troll around
the void
devoid
of direction
their only connection
with Earth
a gravitational line for what it’s worth

it’s not even called THE SUN
it’s just a ball of plasma that runs till it’s done
like that light you keep at the top of the stairs
so when you wake up at night you don’t feel scared

to summarise
re sunrise:
all directions are equivalent
(Newton had theories but remained ambivalent)
I mean – is the universe isotropic?
(hot topic)
does it have uniformity in all orientations?
or is it changeable in some situations?
is the CMB dipole purely kinematic, or does it signal anisotropy of the universe, resulting in the breakdown of the FLRW metric and the cosmological principle?
(I can tell by your frown you’re not convincible
but of course I didn’t KNOW all that
as a matter of fact
it couldn’t be easier
I copied it straight from wikipedia)

Anyway – it’s five o’clock – am I awake? – you betcha
there aren’t any taxis so I’m coming to getcha
