image3_hubble_orbitWe live in an exciting golden-age of science, particularly in astronomy.  With the Hubble Telescope or the Voyager Spacecraft which is leaving our solar system ( the first man made objects to do so)  or even the Kepler Space Observatory spotting extra-solar planets. As we can see further and further our greatest scientists have been asking why does the universe appear to be “fine-tuned” for life?  The fact that we are here, able to observe and ask these questions, learn about laws of the universe, depends on the conditions for life to be present.  At the relatively ‘smaller’ level of our solar system – our planet is in the ‘Goldilocks Zone’ – i.e. not too hot or cold  for water and therefore life to exist.  At larger galaxy / universe level, there are supposedly  6 dimensionless constants (i.e.  subatomic forces, how gravity interacts with different forces) that if they were slightly different would not permit life to exist anywhere in the universe.

Einstein’s equivalence principle, which states that the laws of physics are the same everywhere has just been brought into question due to research in Chile.  Analysis of the light from distant quasars in 2011 from data from the Very Large Telescope (VLT) in Chile showed that one of the constants of nature appears to be different in different parts of the cosmos, supporting the theory that our solar system is in an area of the Universe that is “just right” for life,.”This finding was a real surprise to everyone,” said John Webb of the University of New South Wales in Sydney, Australia. “The implications for our current understanding of science are profound. If the laws of physics turn out to be merely “local by-laws”, it might be that whilst our observable part of the Universe favors the existence of life and human beings, other far more distant regions may exist where different laws preclude the formation of life, at least as we know it.

einstein-75dffc8af00c56b1cf93b7058f15af1360ac6bca-s6-c30These exciting discoveries seem can give strength to a recent addition to the classical formulations of the arguments for the existence of God.  The argument from intelligibility is one that Pope Benedict is largely responsible for.  As a young theologian the then Joseph  Ratzinger commences with the observation that finite being, as we experience it, is marked, through and through, by intelligibility, that it is to say, by a formal structure that makes it understandable to an inquiring mind.   In point of fact, all of the sciences – physics, chemistry, psychology, astronomy, biology, and so forth – rest on the assumption that at all levels, microscopic and macroscopic, being can be known.  Ratzinger argues that the only finally satisfying explanation for this universal objective intelligibility is a great Intelligence who has thought the universe into being.  Our language provides an intriguing clue in this regard, for we speak of our acts of knowledge as moments of “recognition,” literally a re-cognition, a thinking again what has already been thought.  Ratzinger cites Einstein in support of this connection: “in the laws of nature, a mind so superior is revealed that in comparison, our minds are as something worthless.”   In this Golden age of Astronomy and discovery of space – could it be  that growing proof of a more finely tuned universe than we originally imagined – gives strength to the argument from intelligibility?

Lovell Telescope, Jodrell Bank Observatory

Two alumni of Manchester who seem to be high-profile but are now sadly dead are Alan Turing and Bernard Lovell.  Turing. mathematical genius, code-breaker extraordinaire, is widely considered to be the father of computing science and artificial intelligence.  Designing the first model  stored-program computer,  he worked on the innovative Manchester Computers project which lead to the development of the first commercially available general purpose computer the Ferranti Mark One.   It is an incredible legacy as arguably computers have been the most significant technological advance in the modern age.   Bernard Lovell, sadly died a few weeks ago.  A visionary physicist – his top-secret work on magnetrons during the WW2 helped Allied bombers spot submarine periscopes and Hitler blamed a major naval setback on his inventions.  During this work he spotted other strange stuff – emitting radio frequency waves – cosmic rays perhaps? so after the War he set up the Jodrell Bank Radio Telescope in Cheshire to find out. The worlds biggest steerable radio telescope, its spiralling costs and need for electromagnetic silence (thus blocking local development) led it to be called ‘Lovell’s folly’ – and he was staring bankruptcy and public hostility in the face. Until the space race started and the launch of the Russian Sputnik sattelites. When it became obvious that the only place in the world that could track them was Jodrell Bank – overnight he became a hero again!

Importantly for our work in the Chaplaincy is also his interest in questions of science and faith.  A committed Christian, and organist in his local parish church, St Peter’s, Swettenham, for 40 years, with the big questions he believed cosmology must give way to metaphysics.  This is important for me as we are developing a Faith and Science group here in Manchester.  It is striking how many of the students who come into the chaplaincy are scientists.  Talking to them it is clear that they find it increasingly difficult to talk about their faith openly with scientific colleagues, or in a science lab. We would like to counteract that by developing a thriving Faith and Science community here – with a specialist library, lectures.  It may be that we will have an annual lecture named after Bernard Lovell.  It is a shame that due to the aggressive and intolerant atheism of people like Dawkins, the wise, gentler voices such as Lovell’s seem to be drowned out.  The Lovell Telescope will now be the nerve centre of what will be the world’s biggest telescope, the multinational Square Kilometre Array. But until his recent death Bernard Lovell remained modest about the limits of its discoveries. In his 90s he said he had never in his life been “faced with so many unanswered questions as now”.  And in his final Reith lecture he sketched out wise and telling parameters for faith and science when he said:

I am no more surprised or distressed at the limitation of science when faced with this great problem of creation than I am at the limitation of the spectroscope in describing the radiance of a sunset or at the theory of counterpoint in describing the beauty of a fugue.

Arisaig – just to make you jealous ….

I am spending an unexpected week up in the West Highlands of Scotland in a beautiful place called Arisaig, helping out with a supply for the parish.  I am relishing the beautiful blue seas,  white / silver beaches and a welcome re-acquaintance with the sun ( I just saw on the news Edinburgh only had 1.6hrs of sun shine the first 10 days of July!).  Another great part of being up in the ‘remote’ highlands is that there is very little light pollution up here – so the nights can be very dark – perfect if you are an enthusiastic stargazer like me. There is nothing like spending an hour – in a comfortable spot, wrapped up warmly to gaze at the immensity of the heavens, counting shooting stars, identifying constellations, working out asterisms within the constellations,  squinting and trying to split binary stars with binoculars.  Planet spotting is great fun too – especially with the new apps on smartphones that effectively give you a portable planetarium.  Of course the planets do not generate light (unlike stars) but reflect the light from our star, the Sun, back to us.  I learnt that the technical term for the amount of light a celestial body reflects is Albedo and it is low for the Earth, as we reflect only about 0.36 percent of the light that comes in. The Moon is a bit better though and this week we can get the chance to see ‘Earth-shine’ reflected on the moons surface.

Earth Shine and the Old Moon in the New Moons arms – coming soon to a sky near you!

This week, everywhere, a new Moon is rising giving us a chance to bathe in this Earthshine, the light from the Earth that illuminates the Moon.  Right now is the perfect time to look for this enchanting phenomenon.  So if you look at the photo to the left – you will see a  new moon with about 10%  positioned so the sunlight hits it and bounces down to Earth (the bright bit).The rest of  the Moon, however, is positioned just right for the light from the sun to hit the Earth, bounce to the Moon, and come back down to the Earth again (the greyer 90%). That’s why we see, “The Old Moon in the New Moon’s arms.”  The best time to see it is just around sunset  when the reflected Earthshine is brightest.

Happy moon spotting!
