Our nearest star, aka “the Sun,” sent an M-2 Coronal Mass Ejection our way on 14 July. Barry Snyder speaks about the effects of such phenomena on Earth and Earthlings, especially during this time in the cycle of polar reversal and weakening of Earth’s magnetic field. Musical guest Tim Blais provides an explanation of the one-way arrow of Entropic Time with his A Capella Science parody of a familiar Billy Joel song, and Benjamin the Donkey offers commentary with his Limericks of Doom.  Sequitur theme music is by Zympht.

Entropic Time
Tim Blais

Whoa, arrow of entropic time.
Whoa, arrow of entropic time.

If you made a scrambled egg tonight,
There’d be no return to yolk and white.
And when it’s fried, you
Can’t turn it back to raw food.
That is the arrow of entropic time!

Structure decomposes til it’s gone.
Hot spots cool and entropy grows on.
My room was cleaner –
Now looks like Godzilla’s been there.
Not my fault; blame it on entropic time.

Whoa, arrow of entropic time.
Whoa, arrow of entropic time.

Stars explode and leaves turn brown and fall.
That’s thermodynamics’ second law.
But from a deep view,
That doesn’t need to be true.
Time-symmetry precludes entropic time.

Maybe this won’t last very long.
Our cosmos’s light, a fluctuation.
In that case, it’s probable we are
A brain without a jar,
Decomposed in a moment.

Who knows if that’s true and I’ll be gone –
Thermalized before you hear this song.
I’ll take my chances
Though I can’t disprove these answers.
‘Cause there’s a reason for entropic time.

One must go right back to the start –
The order from whence all things fell apart.
All life hinges on that state that was.
We hope to find its cause
But it’s more than we know now.

Maybe there’s a time-symmetric space
Birthing big bangs all over the place
That then disperse as
New baby universes
With their own direction of entropic time.

Whoa, arrow of entropic time.
Whoa, arrow of entropic time.
Whoa, arrow of entropic time.
Whoa, arrow of entropic time.
