DID you know that when it comes to molecular organisation and dis-organisation, high entropy will almost always triumph over low entropy?

It’s due to the unstoppable ‘arrow of time’ and explains why our solar system is on a slow, but unavoidable path to total destruction because all matter is constantly compelled to degrade, disintegrate and die.

At least I think that’s what Professor Brian Cox meant.

Call me blonde, but in his Wonders of the Universe (Sunday BBC2, 9pm), I struggled to get my head around the enormity of what the rock-star of the cosmos was saying.

I put this down, not to me being thick, though some may argue, but to three things distracting me.

One, the endless psychedelic images of nebulas, constellations and space matter set against either sweeping, classical violins or heavy-metal guitars.

Two, even when Coxy was astride a mountain wearing the sun as a halo, and saying stuff like: “The second law of thermodynamics”, my mind wandered to how his pudding basin hair and perfect teeth made him look a wee bit like Johnny Depp as Willie Wonka.

And three, attention trivia fans, the knowledge that in 1997 he was a member of D’Ream when their song ‘Things Can Only Get Better’ became the anthem of New Labour. Yes, really.

As history has noted, things didn’t really get better for Labour, but the professor on the other hand, quite literally reached for the skies – and got them.

During a fallow period when D’Ream clearly weren’t living the D’ream, he obtained a first class honours degree in physics from the University of Manchester and a PhD in High Energy Particle Physics at the DESY laboratory in Hamburg and is now TV and radio’s must-have geek, the prince of planets, the knight of the night skies.

This new show is his universe and he strode majestically across it while informing us that our solar system is stuffed, albeit using poetic language like: “It will be the end of the age of starlight” and “There will be one, last perfect day on earth” – yeah, before it becomes a boiling, uninhabitable death-trap.

As a child I was a sucker for galaxies and milky ways, and not just the sweets; in particular I loved the TV show, Carl Sagan’s Cosmos, where the New York scientist with the sort of voice you’d imagine God to have, told me about life, the universe and everything, while wearing a fabulous scarlet turtle neck.

Sagan, who died in 1996, was the knees, as in the bee’s ones, and I hung on his every incomprehensible word.

Dr Cox is his reincarnation for the noughties, but there remains only one master of the universe – ladies and gentlemen, I give you Sir Patrick Alfred Caldwell-Moore.

Lord of The Sky at Night (Sunday, BBC1, 11.25) – the world’s, get that, the world’s, longest running television show – this ancient, monacled telescopeer is so astonishing, so interesting, so super-knowing, so, well, huge, he’s almost a planet in his own right.

What our Patrick, 88, doesn’t know about what’s going on above our heads in the night-time you could write on the planet’s smallest sub-atomic particle. This week’s Sky at Night was the 700th episode, and Sir Pat was in the mood for celebrating. Which meant inviting even more egg-heads than usual round his gaff in Selsey for a bit of hard-core astro action.

Cox was there, so was Martin Rees, a super-boffin and the official Astronomer Royal, plus Lucie Green, who knows absolutely everything about the sun, which is actually a star, of course.

So far, so scientific.

But wait, who is the clog-wearing geek with the giant mop of mad grey hair lurking in the shadows?

No, not as Rees pointed out, the first living scientist he’s met who’s the spit of Albert Einstein, but Brian May from Queen.

Well I never. Turns out May has long been a bit of a space cadet and is in total awe of Moore. He told a sweet tale of how a small book discovered in his school library when he was a lad and simply called The Earth by the great man had triggered his life-long love of the planets.

One-by-one, all the invited guests cited him as their inspiration.

His reaction?

“Yes, yes, very good, now shall we move on to the next question? I think it’s about Red Dwarves...”

What a star!
