"Kapitein Kathryn Janeway krijgt een rondleiding van admiraal Patterson tijdens haar eerste dag aan boord van de USS Voyager. Ondertussen moet Seven of Nine, vermomd als een vaandrig, een wapen onderzoeken dat aan boord van het sterrenschip is geplaatst. Ze rapporteert haar bevindingen aan kapitein Braxton, die meer informatie over de locatie van het wapen en de tijdsindex waarin het geplaatst is wil weten. Janeway krijgt een waarschuwing over een chroniton flux, waardoor ze Seven bijna ontdekt. Braxton straalt Seven echter net op tijd weg, maar aangekomen op het tijdschip USS Relativity blijkt ze dood te zijn. Braxton beveelt zijn mannen om terug in de tijd te gaan en Seven nogmaals naar de Relativity te halen. Dit zou al de derde keer worden dat Seven de taak krijgt om de bemanning te redden. Aan boord van de Voyager ontstaan namelijk tijdgerelateerde verstoringen en het ruimte-tijd continu\u00FCm rond het schip begint scheuren te vertonen. Hierdoor ontstaan bizarre paradoxen en de bemanning krijgt last van ruimteziekte. Seven en B'Elanna Torres onderzoeken de verstoringen en Seven's oculair implantaat registreert het apparaat dat deze veroorzaakt. Voordat ze de kans krijgen om het apparaat verder te onderzoeken beveelt Janeway haar bemanning om Voyager te verlaten. Seven wordt wederom verwelkomd door de bemanning van de Relativity. Het is 500 jaar in de toekomt en Braxton wil het mysterie betreft het tijdelijke apparaat opgelost hebben. Zijn bemanning heeft Seven uitgekozen, omdat ze door haar oculaire implantaat in staat is om storingen in ruimte/tijd waar te nemen. Nadat ze haar overtuigd hebben keert ze terug naar Voyager. Ze komt twee jaar voordat ze zich oorspronkelijk bij de bemanning zou voegen aan boord. Het schip wordt aangevallen door de Kazon en Braxton is van mening dat de saboteur in deze tijdsindex het wapen ge\u00EFnstalleerd heeft. Seven moet hem opsporen en tegenhouden. Seven onderzoekt het schip, maar vindt geen sporen van het apparaat of de saboteur. Janeway ontdekt een chroniton flux en herinnert zich dat ze die twee jaar eerder ook al eens gezien heeft. Ze gaat samen met Tuvok op onderzoek uit en ze betrappen Seven. Ze herkent Seven nog van haar eerste dag aan boord van Voyager en eist een verklaring. Ondanks de protesten van Braxton en de mogelijke schade aan de tijdlijn legt Seven haar missie uit. Janeway laat zich moeilijk overtuigen door het bijna ongelofelijke verhaal dat ze te horen krijgt. Zodra ze echter instemt om Seven te helpen duurt het niet lang voordat ze de saboteur gevonden hebben, kapitein Braxton. Deze versie van Braxton lijdt zwaar onder tijdelijke psychose en beweert dat Janeway de schuld is van zijn ballingschap eeuwen terug op Aarde. Hij springt plots terug in de tijd en Seven achtervolgt hem. Zodra hij in een krachtveld wordt vastgezet springt hij weer vijf jaar vooruit in de tijd. Seven lijdt ondertussen zwaar onder het feit dat ze al zoveel tijdsprongen heeft gemaakt. Ze vertelt de versie van zichzelf in dat jaar dat ze verder moet gaan met de achtervolging op Braxton. Met hulp van Janeway weet ze Braxton te pakken te krijgen. De tijdlijn is door alle mislukte pogingen behoorlijk verstoord geraakt en luitenant Ducane verzoekt Janeway om de tijdlijn te herstellen. Ze moet terug in de tijd gaan om de oorspronkelijke plaatsing van het apparaat tegen te gaan. Ducane heeft eerder al de hedendaagse versie van Braxton opgepakt en in de gevangenis gegooid voor \"daden die hij zou gaan plegen\". Janeway weet Braxton tegen te houden en daarmee komt er een einde aan haar taak. De tijdlijn is hersteld, de drie versies van Braxton zullen worden samengevoegd en Janeway en Seven mogen terugkeren naar hun eigen tijdindex."@nl . "epprod"@en .

Aristotle's notion of the motion of bodies impeded understanding of gravitation for a long time. He believed that force could only be applied by contact; force at a distance being impossible, and a constant force was required to maintain a body in uniform motion. Copernicus's view of the solar system was important as it allowed sensible consideration of gravitation. Kepler's laws of planetary motion and Galileo's understanding of the motion and falling bodies set the scene for Newton's theory of gravity which was presented in the Principia in 1687. Newton's law of gravitation is expressed by where F is the force between the bodies of masses M1, M2 and d is the distance between them. G is the universal gravitational constant. After receiving their definitive analytic form from Euler, Newton's axioms of motion were reworked by Lagrange, Hamilton, and Jacobi into very powerful and general methods, which employed new analytic quantities, such as potential, related to force but remote from everyday experience. Newton's universal gravitation was considered proved correct, thanks to the work of Clairaut and Laplace. Laplace looked at the stability of the solar system in Trait\u00E9 du M\u00E9canique C\u00E9leste in 1799. In fact the so-called three-body problem was extensively studied in the 19th Century and was not properly understood until much later. The study of the gravitational potential allowed variations in gravitation caused by irregularities in the shape of the earth to be studied both practically and theoretically. Poisson used the gravitational potential approach to give an equation which, unlike Newton's, could be solved under rather general conditions. Newton's theory of gravitation was highly successful. There was little reason to question it except for one weakness which was to explain how each of the two bodies knew the other was there. Some profound remarks about gravitation were made by Maxwell in 1864. His major work A dynamical theory of the electromagnetic field (1864) was written to explain the electromagnetic action between distant bodies without assuming the existence of forces capable of acting directly at sensible distances. At the end of the work Maxwell comments on gravitation. After tracing to the action of the surrounding medium both the magnetic and the electric attractions and repulsions, and finding them to depend on the inverse square of the distance, we are naturally led to inquire whether the attraction of gravitation, which follows the same law of the distance, is not also traceable to the action of a surrounding medium. However Maxwell notes that there is a paradox caused by the attraction of like bodies. The energy of the medium must be decreased by the presence of the bodies and Maxwell said: As I am unable to understand in what way a medium can possess such properties, I cannot go further in this direction in searching for the cause of gravitation. In 1900 Lorentz conjectured that gravitation could be attributed to actions which propagate with the velocity of light. Poincar\u00E9, in a paper in July 1905 (submitted days before Einstein's special relativity paper), suggested that all forces should transform according the Lorentz transformations. In this case he notes that Newton's law of gravitation is not valid and proposed gravitational waves which propagated with the velocity of light. In 1907, two years after proposing the special theory of relativity, Einstein was preparing a review of special relativity when he suddenly wondered how Newtonian gravitation would have to be modified to fit in with special relativity. At this point there occurred to Einstein, described by him as the happiest thought of my life, namely that an observer who is falling from the roof of a house experiences no gravitational field. He proposed the Equivalence Principle as a consequence: ... we shall therefore assume the complete physical equivalence of a gravitational field and the corresponding acceleration of the reference frame. This assumption extends the principle of relativity to the case of uniformly accelerated motion of the reference frame. After the major step of the equivalence principle in 1907, Einstein published nothing further on gravitation until 1911. Then he realised that the bending of light in a gravitational field, which he knew in 1907 was a consequence of the equivalence principle, could be checked with astronomical observations. He had only thought in 1907 in terms of terrestrial observations where there seemed little chance of experimental verification. Also discussed at this time is the gravitational redshift, light leaving a massive body will be shifted towards the red by the energy loss of escaping the gravitational field. Einstein published further papers on gravitation in 1912. In these he realised that the Lorentz transformations will not apply in this more general setting. Einstein also realised that the gravitational field equations were bound to be non-linear and the equivalence principle appeared to only hold locally. This work by Einstein prompted others to produce gravitational theories. Work by Nordstr\u00F6m, Abraham and Mie was all a consequence of Einstein's, so far failed, attempts to find a satisfactory theory. However Einstein realised his problems. If all accelerated systems are equivalent, then Euclidean geometry cannot hold in all of them. Einstein then remembered that he had studied Gauss's theory of surfaces as a student and suddenly realised that the foundations of geometry have physical significance. He consulted his friend Grossmann who was able to tell Einstein of the important developments of Riemann, Ricci (Ricci-Curbastro) and Levi-Civita. Einstein wrote: ... in all my life I have not laboured nearly so hard, and I have become imbued with great respect for mathematics, the subtler part of which I had in my simple-mindedness regarded as pure luxury until now. In 1913 Einstein and Grossmann published a joint paper where the tensor calculus of Ricci and Levi-Civita is employed to make further advances. Grossmann gave Einstein the Riemann-Christoffel tensor which, together with the Ricci tensor which can be derived from it, were to become the major tools in the future theory. Progress was being made in that gravitation was described for the first time by the metric tensor but still the theory was not right. When Planck visited Einstein in 1913 and Einstein told him the present state of his theories Planck said: As an older friend I must advise you against it for in the first place you will not succeed, and even if you succeed no one will believe you. Planck was wrong, but only just, for when Einstein was to succeed with his theory it was not readily accepted. It was the second half of 1915 that saw Einstein finally put the theory in place. Before that however he had written a paper in October 1914 nearly half of which is a treatise on tensor analysis and differential geometry. This paper led to a correspondence between Einstein and Levi-Civita in which Levi-Civita pointed out technical errors in Einstein's work on tensors. Einstein was delighted to be able to exchange ideas with Levi-Civita whom he found much more sympathetic to his ideas on relativity than his other colleagues. At the end of June 1915 Einstein spent a week at G\u00F6ttingen where he lectured for six 2 hour sessions on his (incorrect) October 1914 version of general relativity. Hilbert and Klein attended his lectures and Einstein commented after leaving G\u00F6ttingen: To my great joy, I succeeded in convincing Hilbert and Klein completely. The final steps to the theory of general relativity were taken by Einstein and Hilbert at almost the same time. Both had recognised flaws in Einstein's October 1914 work and a correspondence between the two men took place in November 1915. How much they learnt from each other is hard to measure but the fact that they both discovered the same final form of the gravitational field equations within days of each other must indicate that their exchange of ideas was helpful. On the 18th November he made a discovery about which he wrote For a few days I was beside myself with joyous excitement. The problem involved the advance of the perihelion of the planet Mercury. Le Verrier, in 1859, had noted that the perihelion (the point where the planet is closest to the sun) advanced by 38 per century more than could be accounted for from other causes. Many possible solutions were proposed, Venus was 10% heavier than was thought, there was another planet inside Mercury's orbit, the sun was more oblate than observed, Mercury had a moon and, really the only one not ruled out by experiment, that Newton's inverse square law was incorrect. This last possibility would replace the 1/d2 by 1/dp, where p = 2+\u03B5 for some very small number \u03B5. By 1882 the advance was more accurately known, 43\" per century. From 1911 Einstein had realised the importance of astronomical observations to his theories and he had worked with Freundlich to make measurements of Mercury's orbit required to confirm the general theory of relativity. Freundlich confirmed 43\" per century in a paper of 1913. Einstein applied his theory of gravitation and discovered that the advance of 43\" per century was exactly accounted for without any need to postulate invisible moons or any other special hypothesis. Of course Einstein's 18 November paper still does not have the correct field equations but this did not affect the particular calculation regarding Mercury. Freundlich attempted other tests of general relativity based on gravitational redshift, but they were inconclusive. Also in the 18 November paper Einstein discovered that the bending of light was out by a factor of 2 in his 1911 work, giving 1.74\". In fact after many failed attempts (due to cloud, war, incompetence etc.) to measure the deflection, two British expeditions in 1919 were to confirm Einstein's prediction by obtaining 1.98\" \u00B1 0.30\" and 1.61\" \u00B1 0.30\". On 25 November Einstein submitted his paper The field equations of gravitation which give the correct field equations for general relativity. The calculation of bending of light and the advance of Mercury's perihelion remained as he had calculated it one week earlier. Five dys before Einstein submitted his 25 November paper Hilbert had submitted a paper The foundations of physics which also contained the correct field equations for gravitation. Hilbert's paper contains some important contributions to relativity not found in Einstein's work. Hilbert applied the variational principle to gravitation and attributed one of the main theorem's concerning identities that arise to Emmy Noether who was in G\u00F6ttingen in 1915. No proof of the theorem is given. Hilbert's paper contains the hope that his work will lead to the unification of gravitation and electromagnetism. In fact Emmy Noether's theorem was published with a proof in 1918 in a paper which she wrote under her own name. This theorem has become a vital tool in theoretical physics. A special case of Emmy Noether's theorem was written down by Weyl in 1917 when he derived from it identities which, it was later realised, had been independently discovered by Ricci in 1889 and by Bianchi (a pupil of Klein) in 1902. Immediately after Einstein's 1915 paper giving the correct field equations, Karl Schwarzschild found in 1916 a mathematical solution to the equations which corresponds to the gravitational field of a massive compact object. At the time this was purely theoretical work but, of course, work on neutron stars, pulsars and black holes relied entirely on Schwarzschild's solutions and has made this part of the most important work going on in astronomy today. Einstein ha reached the final version of general relativity after a slow road with progress but many errors along the way. In December 1915 he said of himself: That fellow Einstein suits his convenience. Every year he retracts what he wrote the year before. Most of Einstein's colleagues were at a loss to understand the quick succession of papers, each correcting, modifying and extending what had been done earlier. In December 1915 Ehrenfest wrote to Lorentz referring to the theory of November 25, 1915. Ehrenfest and Lorentz corresponded about the general theory of relativity for two months as they tried to understand it. Eventually Lorentz understood the theory and wrote to Ehrenfest saying I have congratulated Einstein on his brilliant results. Ehrenfest respondedIn the early 1900s, there was a distinct change in how we saw the world \u2013 this was the point where physics starts to diverge quite distinctly from common sense. This was the era of time slowing down; objects changing size due to their speed; space and time becoming unified; invisible forms of light; radioactive decay; gravity becoming a product of space and time bending; black holes; and the quantum theory... An impossibly huge amount of impacts to our common sense word-view, all centred in the first half of the 20th century."@en . "2371"^^ .
