  1. Space and Time with Sam Neill

    I was very sad this morning to read the news that Sam Neill has passed away at the age of 78. He was a very fine and exceptionally versatile actor. Among many other roles I remember him well as the sadistic and corrupt Chief Inspector Chester Campbell in Peaky Blinders. I was impressed by his convincing Ulster accent but then found out he was actually born in Omagh, County Tyrone.

    About 25 years ago (!) I made a very brief appearance in a BBC documentary series called Space for which Sam Neill (left) was the narrator. Apparently he only agreed to do the job on condition that they would film his segments at his home in New Zealand. I remember talking to the production team about Sam Neill and they all said he was not only very professional in his work but also a very nice man. These things don’t always go together…

    After the episode I was in – the last of six – was broadcast, my Mam rang me. She didn’t mention my part at all, but asked “That Sam Neill, is he nice?”. I had to explain that I never met him, as they filmed his segments after all the other location sequences. “Oh well,” she said. “At least he knew your name”.

    The following clip shows the item I took part in. Originally we were going to demonstrate wormholes using a snooker table, clever editing and reversed video. The producer, Jeremy Turner,  decided that wouldn’t look spectacular enough so instead we went to St Anton in Austria: I was flown over the Alps in a helicopter and then driven through the Arlberg tunnel in an impressively fast car. Well worth the cost to license fee payers, I’m sure, even if the three-day trip to Austria by me and a crew of six as well as the hire of the helicopter ended up as a mere three minutes of screen time.

    The item is daft, I know, and I don’t really believe any of that stuff about wormholes… but it was great fun doing it. I remember after the shoot we had a few drinks to wrap it up then left on a very early flight the next morning to the UK. I got back to Nottingham University just in time for a 10am lecture.

    Anyway, the episode I was in was called To Boldly Go. I remember suggesting to the producer that the only way to travel faster than light in the manner required was with a split infinitive drive, but they didn’t use that in the final script.

    Notice how, in the helicopter sequence, I give the appearance of being completely terrified. A fine piece of acting by me, I thought. *Cough*

  21. Today's #paperOfTheDay is "Why there is Nothing rather than something: A theory of the cosmological constant" from 1988. Like yesterday's paper, it deals with the intersection between quantum field theory and #generalRelativity, but the 30 years between them clearly show. Coleman's 1988 paper is an argument in the style of that time (which structurally is quite similar to much of the older #renormalon literature): Heuristic manipulations of formal objects such as the wave function of the universe, or divergent sums over all spacetime geometries. The outcome of this argument is that if #wormholes exist (caused by quantum effects at a scale that is much smaller than observations, but larger than the Planck scale), they can drive the cosmological constant to zero in an Euclidean path integral formulation of general relativity. As always with Coleman, the language is quite funny and frank about the paper's limitations: He writes "Although I find this theory in many ways very attractive, I must honestly stress its speculative character. It rests on wormhole dynamics and the Euclidean formulation of quantum gravity. This is doubly a house built on sand. [...] the Euclideon formulation of gravity is not a subject with firm foundations and clear rules of procedure; indeed, it is more like a trackless swamp". Observations like these have by now, 30 years later, led to a style of theoretical physics that is much more systematic and mathematical than in the 1980s, but also sometimes less intuitive. #dailyPaperChallenge doi.org/10.1016%2F0550-3213(88

  29. Quantum tunnelling and wormholes are usually treated as separate phenomena.
    They aren’t.
    Both are: • access to classically forbidden regions
    • permitted briefly, not permanently
    • exponentially suppressed by scale
    • locally causal, globally surprising
    Same geometric process.
    Different size of deformation.
    Physics didn’t forbid them.
    It just made them expensive.
