This is an interesting animation of 45 minutes
or so in duration illustrating the scale of just a
small portion of the Solar System and the speed
of light:
I think this is super cool way to understand the enormity of
space. You might want to note in your description that if you
were actually a photon traveling at the speed of light you
would not experience any time or distance. The time you are
expressing is the time as measured by a stationary observer.

Wow! Photons! Speedy little buggers, aren't they? I haven't
been on a ride like this since Dr. Eleanor Arroway (Jodie
Foster's character) took her eighteen minute voyage to
nowhere!

Like everything else in physics, our Universe strives to exist
in the lowest possible energy state possible. But around 10-36
seconds after the Big Bang, inflationary cosmologists believe
that the cosmos found itself resting instead at a "false vacuum
energy" – a low-point that wasn't really a low-point. Seeking
the true nadir of vacuum energy, over a minute fraction of a
moment, the Universe is thought to have ballooned by a factor
of 10+50!
