Part 14 (1/2)

He wrapped an arm round my waist, pulled me close, and kissed my lips.

I gave a small shriek of surprise. Asian honeypot indeed! He did not release me, but showered compliments on me, saying he had adored me ever since he had set eyes on me in the science unit. I did not mind the compliments. When he started to kiss me again, and I felt the warmth of his body against me, I found myself returning them.

I rejoiced when his tongue slipped into my mouth. I was becoming quite enthusiastic when the door opened and Tom and some others came in to congratulate Thorgeson on his exposition. This was one time when I felt really mad at Tom.

Back we marched into the hall. Thorgeson seemed quite calm. I was trembling. He had been about to grab my b.r.e.a.s.t.s under my clothes, and I could not decide how I would feel about that. I was furious with the situation. It was all I could do to sit there and listen to him. How should I deal with him when the lecture was over - with that Euclid looking on, too?

However, I now saw a new kind of pa.s.sion in Jon -not a physical pa.s.sion but an intellectual one, as he took over from Euclid and spoke of the next epoch of scientific discovery.

'Euclid and I were talking about the smudge mystery,' he said when the audience had settled down. 'I will skip some years of confusion and frustration and speak about the year 2024. That was the year when there were two breakthroughs, one experimental, one theoretical.

'The experimental breakthrough came when SHC got up to full power, far beyond anything originally planned for the unbuilt SSC, using a further innovation contributed by the Indonesian physicist, Jim Kopamtim. Lo and behold at far greater energies than were achieved previously, another smudge was found!

'So the Higgs smudge had to be rechristened the alpha-smudge, while the new one went by the name of beta-smudge.

The theoretical breakthrough - well, I should say it came a while before the SHC observations. A brilliant young Chinese mathematician, Chin Lim Chung, achieved a completely reformulated theoretical basis for particle physics as it stood at the time. Miss Chin introduced some highly sophisticated new mathematical ideas. She showed how a permanent smudge could indeed come about on the Ng-Robinson Plot, but but the culprit could not possibly be a particle in any ordinary sense. the culprit could not possibly be a particle in any ordinary sense.

'It was a new kind of ent.i.ty entirely. So from henceforth it was simply referred to as a smudge. smudge.

'Soon after the SHC announcement, Chin Lim Chung, working in conjunction with our own Dreiser Hawkwood, figured out that the alpha and beta smudges had to belong to a whole sequence of smudges, at higher and higher energies. It was clear that until this sequence was known as a whole, there was going to be no solution to the mystery of ma.s.s.

'Mother Teresa! It was as though we had discovered a row of galaxies on our doorstep!' As if he could not stop himself, he added, 'The remarkable Miss Chin is still alive and working. I happen to know her daughter.'

Something in Jon's manner, in his very body language, suggested to me that this lady must have been his Chinese lover, back on Earth.

Euclid: 'You cannot forever go on building bigger and bigger machines. So why did not the physicists just give up on the mystery?'

'Well, we don't give up easily.' He shot me a glance as he said this. 'It was hoped that once the gamma-smudge was found, then the mystery of ma.s.s could be resolved after all.'

Euclid. 'So they built an even bigger super-duper collider, did they? Where this time? Siberia?'

'On the Moon.'

He showed a vidslide of a gleaming section of tube crawling across the Mare Imbrium.

'A collider that formed a ring completely round the lunar surface. Alas for ambition! The Luna project turned out to be a total failure, at least with regard to finding the gamma-smudge. It did produce some data, relatively minor but useful. But no new smudge.'

Euclid: 'A costly mistake, wasn't it? Why did it fail?'

'The bill all merged into Lunar expenses, when the Moon was the flavour of the year, in the late 2030s. After a host of teething troubles, the Luna Collider appeared to do more or less what it was intended to do.

'I guess the final disaster rested with nature herself. She just didn't come up with a smudge - not even with the fantastic energy range available to a collider of that size.'

Euclid: 'Why didn't that kill off the whole idea? But you are about to tell us that after that disaster, funding was found to start all over again here - here - on Mars?' on Mars?'

'Politics came into it. The fact that Mars was a UN protectorate made it tempting. Also, there is the precept that even pure science, however expensive it may seem, pays off in the unforeseen end. Consider the case of genetically mutated crops, and how they have contributed to human longevity. Some people are willing to pay for ever-widening horizons, for freeing the human mind from old s.h.i.+bboleths.

'And there were two further chunks of scientific progress to encourage them - and another different kind of development which had been brewing away for some while earlier.'

Euclid: 'They were?'

'Even last century, a number of theoreticians had realised that the enigma of ma.s.s could not be resolved at the energy levels relevant to the Higgs. Why? Well, the very concept of ma.s.s is all tied up with gravitation. Gravitation ... Let me give you an a.n.a.logy, Euclid.

'Another long-standing ”mystery” in particle physics is the mystery of electrical charge. It's a mystery of a sort let's say, although a good number of physicists would claim they understand why electric charge comes about.

'The trouble is that although there are good reasons why electric charge always comes in whole-number multiples of one basic charge - which is one twelfth of the charge of an electron - there's no real understanding why the basic charge has the particular value it happens to have.

'I should say there was a time, late last century, when this basic value was believed to be one third of the electron's charge. Before that it was held to be the electron's charge itself. But the one-third value is the quark charge, and it was still thought that quarks were fundamental. Only after Henry M'Bokoko's theory of leptons and pseudo-leptons was it realised there were yet more elementary ent.i.ties. Things called kliks and pseudo-kliks underlay these particles in the same way quarks underlie the hadrons.

'These kliks, pseudo-kliks and quarks, taken together, gave rise to the basic one-twelfth charge that we know today. A diagram will make that clear.'

He flashed a vidslide in the air. It hung before the audience, a skeletal Rubik's cube in three dimensions.

'Now, there are certain fundamental ”natural units” for the universe - the units Nature herself uses to measure things in the universe. Sometimes these are called Planck units, after the German physicist who formulated them in the early years of last century.

'You see how one finding builds on the previous one. That's part of the fascination which keeps scientists working. In terms of these units, the basic value of the electric charge turns out to be the number 0.007, or thereabouts. This number has never been properly explained. So we don't, even yet, properly understand electric charge. There is, indeed, still a charge mystery. End of a.n.a.logy!'

Euclid, unblinkingly: 'So what follows?'

'The point about the ma.s.s mystery - a point made by a few physicists even as long ago as last century - was that no one would seriously attempt to find a fundamental solution to the charge mystery without bringing the electric field into consideration. Electric charge is the source of the electric field. In the same way, so the argument went, it made little sense trying to solve the mystery of ma.s.s without bringing in the gravitational field. Ma.s.s is, of course, the source of the gravitational field.

'And yet, you see, the original hopes of resolving the mystery of ma.s.s in terms of finding the Higgs particle made absolutely no reference to gravitation.'

Euclid: 'What do you make of all this?'

'It was really a whole bag of wishful thinking. You see, Euclid, finding the Higgs particle was considered just about within the capabilities of the physicists of the time. So, if a solution to the mystery of ma.s.s could be found that way - why, then it would have been pretty well within their grasp.

'But if the issue of the role of gravity had to be seriously faced - there would not have been a hope in h.e.l.l of their finding an answer to the origin of ma.s.s experimentally. They were looking for G.o.d with a candle!

'The energy required would have been what we call the Planck energy - which is larger than the Higgs energy by a factor of at least - well, if we said a few thousand million million, we wouldn't be far out.

'Put it this way. Even a collider the length of the Earth's...o...b..t would not have been enough.' His young-old face broke into a broad grin at the thought of it.

Euclid: 'Yet you tell us that they still did not give up. Why is that?'

'As I told you, it was all wishful thinking. They believed that finding the Higgs would be enough. Anyhow, science often proceeds by being over-optimistic. It's a way in which things do eventually get done. Eventually.

'So although the ma.s.s mystery remains unsolved, we now think our project here could well be close to doing so.'

Euclid: 'More over-optimism?'

'No, this time the case is pretty convincing. The thing is that we are now really facing up to the Planck energy problem.'

Euclid: 'I may be only an android, but as far as I know our experiment does not involve a collider of anything like that length. Or any collider at all.'

Jon released a 3D projection of something like a dark matrix motorway into the lecture room. He let it hang there as he spoke. On that infinite road, smudges shot off endlessly into distance. A cloud of other coloured spots sped after them.

'We're looking at a VR projection of a succession of different smudges, alpha-, beta-, gamma-, delta-smudges. Artist's impression only, of course. You're right, we have no collider on Mars. I've said there were a couple of encouraging breakthroughs. Those breakthroughs make our Mars project possible.

'First breakthrough. The realisation that there was no point in working through this whole gamut of smudges, at greater and greater energy levels, the list continuing for ever.'
