I find this release to be a step up from the first album. I feel as though he's honed in on his own sound here, his own style and brand of heavy space rock. His guitar playing is as exciting as before and the additional instruments here, such as the saxophone only help to enrich the sound palate and strengthen the melodies. In addition, he has enlisted the talents of Timo Ristila keyboards , Petteri Hietamaki sax, flute , Petri Kivimaki sax , all of which play on one or more track.

In each chapter the music goes on uninterrupted or at the very least, flows smoothly from one track to the next, giving the feel of a wholesome lengthy composition with various chapters. From the get go, the music is in full force and upbeat. Reality Strikes and Code are two of the most energetic pieces here, with much vigor and passion as to wake up the dead. There are varied flavours here; Juhani introduces some eastern folkloric elements into his space rock Mind Wide Open. He introduces dynamics and variation in tempo, volume and intensity as he switches for example, from Code to Space Harvest; the former a loud and powerful rock tune lead by solo electric guitar and tenor saxophone, the latter a laid back, slightly odd sounding, atmospheric piece.

At the core of his music sits fun and old-fashioned guitar-lead rock, but it is embellished in a fresh and modern sound and well done arrangements and layering, including sound effects that add to the special sound of this album.

A fun album, one that can serve as a cool breeze on a hot summer day and spice up your mood. Quite modern guitar and bass sounds are blended with an arsenal of classic vintage keyboard instruments. After pleasant lounging in the rocky plateau guarded by solacing trees and future's potential flickering in horizon, more threatening dangers are encountered as a solemn theme gives warning of closing "The Black Hole".

This song builds tension in quite pompous manner, until abrupt reprisal of the entry theme marks the shift to "Inner Peace" sequence, maybe signing the transition past the fatalistic point of no return through event horizon. Instead of morphing to spaghetti, luckily the consciousness is expanded with warm and hippie-oriented tones.

Later these meditations lead to more severe psychic catharsis of "Mind Wild Open". I admit I personally do not like very much the "musical volcano erupts" which are often found in rock music coda's breaking the conventional pop structures, but this moment does not ruin the record either. This deconstruction of psyche is healed with acoustic-leaned Kingston Wall styled dharma moment, and the song is wrapped inside the "Inner Peace" composition, which ties together the musical flow growing to quite cacophonic levels at some point.

From its theme is built a quite groovy and pleasant jam, which is faded out, signaling the vinyl side's ending. The tune is driven to the core of "Code ", as saxophone joins the melodic solo lines attacking the pulsing groove basis of the song, radiating rapid signals of enjoyment. The deranged flight in warped themes is interesting, and there are some catchy theme rising as concrete forms from the messy sea of details.

I admit the union of these conflicting elements creates an interesting composition with extreme contrasts merged, but I'm uncertain if this still is the most pleasant part of this musical journey. The final track "The Last Wave" finds time to expand the flow past eight minutes, and relaxed song with fine guitar melody and solo sequences is really fine, strengthened in some moments with more neurotic harmonic details.

The surges of huge tidal waves end the album, and they seem as a promise that later more chapters would emerge from their embrace. I heard some comments that people knowing both the two currently existing Time Traveller records liked the first one better. I only agree that they are different from the perspective of content's intensity and tendency of musical exploration. If the music is sincere, and the listener is ready to meet the musician as persons they are, I believe a channel of communication may born.

Somehow from my own part I have been lost to this concept, instead of demanding circus acts produced with details matching my own personal fetishes. Maybe the neurotically twisting aural journey could resemble a child in play, adventuring in freedom with a hunger for new experiences, suffering impatience of seeing all the interesting new things without delay. However the album as a complete record is finished with thought, and after several times of listening for few months I feel it works most best as record guiding to the realms of its creator, not so much as a record for relaxing or catching with easy tunes.

The neat gatefold covers resemble this time the sharper style of Hipgnosis, and the human feeling I personally saw in it strengthened my described spiritual experience of the album. The recorded sounds are preserved with quite modern objectives, giving detailed presentation of older vintage synthesizers, but also boosting the heavenly weeping hard rock guitar tones with authentic 's and 's sounds.


The record is also available on CD, but I recommend the fine vinyl artifact for anybody interested of guitar and vintage keyboards driven energetic progressive rock; This music should fit globally to anybody's prog LP turntable, as the weird Scandinavian language is not present on the completely instrumental album. Listed as a heavy prog band, Time Traveller does exactly what the band name says; travel in time.

A long journey back in time. Well, in the history of rock, at least. Although some references to Sibelius and Bach is visible, we constrain ourselves to - Their platform is heavy prog, but the music is so much more varied than that. I am sure I have missed out on many other bands too. But in short, the music is somewhere between heavy prog, rock'n'roll, blues, space rock, proto prog and krautrock. There are some wonderful use of Hammond organs, electric guitars, bass and drums here. That gives the music a sound taking us back to the s.

If someone told me this album was released in , I would had believed them.

The sound is great and the band does a superb job. The lack of some great songs are a big loss though and my major gripe with this album. But I have to admit this album is growing on me like hair is growing on my head. I love the eerie Hammond sound on this album. There is no doubts this band has tonnes of both potential and quality.

So overall, this is a very good album and it is inbetween between three and four points. I guess I need to get their debut album too after been listening to this album for some days. I enjoy all this time travelling. After listening the music I have to admit that Juhani appears to be really talented musician, providing ace guitar playing and comprehensive palette of vintage keyboard sounds to his compositions. Album has fine clear sounds no fuzzy underground analog stuff here , and here are nice ambiences and effects are arranged between the main parts containing much to listen.

An excitement arose in me quite quickly; So very, very, very well played These people playing here have not been tripping in the record studio with chemicals, but really focused to this thing. The music is also quite alive though most instruments are played by one person in studio. It sounds alive, containing much impulsive playing. Keyboard flavored and positive mild heavy rock sound with unconventional rhythms fit's quite well to the description Rush, which whole career sound could be an influence to this music, though there isn't similar pauses in rhythms and so much arranged elements than in the music of the group compared neither is any melody or riff totally similar to theirs.

Also little less psychedelic incarnation of Kingston Wall could be an association. First Chapter ends to mellower and slower part for guitar solo runs, sounding like studies of themes of Jimi Hendrix's "Third Stone from The Sun" licks. Second Chapter starts running headlong towards the paths familiar of style from earlier songs, "long waited" Mellotrons are presented, and also many wonderful composed melodies among the more impulsive sounding details. The music changes to quiet lingering medley, starting to grow tension which is released nicely like the song name suggests, featuring some traditional folk sounds with violin as a nice spice in the soup.

In the end music suddenly changes to a Mongolian monastery soundscape, ending the trip maybe little weirdly but not to total disappointment. Samuel Madden 's Memoirs of the Twentieth Century is a series of letters from British ambassadors in and to diplomats in the past, conveying the political and religious conditions of the future. An Anachronism , written for the Dublin Literary Magazine [9] by an anonymous author in He encounters the Venerable Bede in a monastery and explains to him the developments of the coming centuries.

However, the story never makes it clear whether these events are real or a dream. Alexander, son of Philip of Macedon by Alexander Veltman published in Charles Dickens 's A Christmas Carol has early depictions of time travel in both directions, as the protagonist, Ebenezer Scrooge, is transported to Christmases past and future. Other stories employ the same template, where a character naturally goes to sleep, and upon waking up find themselves in a different time. In this story, the protagonist is transported to the prehistoric past by the magic of a "lame demon" a French pun on Boitard's name , where he encounters a Plesiosaur and an apelike ancestor and is able to interact with ancient creatures.

This may have been the first story to feature an alternate history created as a result of time travel. However, the mechanism borders on fantasy. An unusual clock, when wound, runs backwards and transports people nearby back in time. The author does not explain the origin or properties of the clock. Wells 's The Time Machine popularized the concept of time travel by mechanical means. Some theories, most notably special and general relativity , suggest that suitable geometries of spacetime or specific types of motion in space might allow time travel into the past and future if these geometries or motions were possible.

Many in the scientific community believe that backward time travel is highly unlikely. Any theory that would allow time travel would introduce potential problems of causality. Some physicists, such as Novikov and Deutsch, suggested that these sorts of temporal paradoxes can be avoided through the Novikov self-consistency principle or to a variation of the many-worlds interpretation with interacting worlds. Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light , such as cosmic strings , transversable wormholes , and Alcubierre drive.

The theory of general relativity describes the universe under a system of field equations that determine the metric , or distance function, of spacetime. There exist exact solutions to these equations that include closed time-like curves , which are world lines that intersect themselves; some point in the causal future of the world line is also in its causal past, a situation which is akin to time travel.

Whether general relativity forbids closed time-like curves for all realistic conditions is still being researched. Wormholes are a hypothetical warped spacetime which are permitted by the Einstein field equations of general relativity.

  • One end of the wormhole is accelerated to some significant fraction of the speed of light, perhaps with some advanced propulsion system , and then brought back to the point of origin. Alternatively, another way is to take one entrance of the wormhole and move it to within the gravitational field of an object that has higher gravity than the other entrance, and then return it to a position near the other entrance. For both of these methods, time dilation causes the end of the wormhole that has been moved to have aged less, or become "younger", than the stationary end as seen by an external observer; however, time connects differently through the wormhole than outside it, so that synchronized clocks at either end of the wormhole will always remain synchronized as seen by an observer passing through the wormhole, no matter how the two ends move around.

    One significant limitation of such a time machine is that it is only possible to go as far back in time as the initial creation of the machine; [20]: According to current theories on the nature of wormholes, construction of a traversable wormhole would require the existence of a substance with negative energy, often referred to as " exotic matter ".

    More technically, the wormhole spacetime requires a distribution of energy that violates various energy conditions , such as the null energy condition along with the weak, strong, and dominant energy conditions. However, it is known that quantum effects can lead to small measurable violations of the null energy condition, [30]: In , Matt Visser argued that the two mouths of a wormhole with such an induced clock difference could not be brought together without inducing quantum field and gravitational effects that would either make the wormhole collapse or the two mouths repel each other.

    However, in a paper, Visser hypothesized that a complex " Roman ring " named after Tom Roman configuration of an N number of wormholes arranged in a symmetric polygon could still act as a time machine, although he concludes that this is more likely a flaw in classical quantum gravity theory rather than proof that causality violation is possible.

    Another approach involves a dense spinning cylinder usually referred to as a Tipler cylinder , a GR solution discovered by Willem Jacob van Stockum [35] in and Kornel Lanczos [36] in , but not recognized as allowing closed timelike curves [37]: If a cylinder is infinitely long and spins fast enough about its long axis, then a spaceship flying around the cylinder on a spiral path could travel back in time or forward, depending on the direction of its spiral.

    However, the density and speed required is so great that ordinary matter is not strong enough to construct it. A similar device might be built from a cosmic string , but none are known to exist, and it does not seem to be possible to create a new cosmic string. Physicist Ronald Mallett is attempting to recreate the conditions of a rotating black hole with ring lasers, in order to bend spacetime and allow for time travel.

    A more fundamental objection to time travel schemes based on rotating cylinders or cosmic strings has been put forward by Stephen Hawking, who proved a theorem showing that according to general relativity it is impossible to build a time machine of a special type a "time machine with the compactly generated Cauchy horizon" in a region where the weak energy condition is satisfied, meaning that the region contains no matter with negative energy density exotic matter.

    Solutions such as Tipler's assume cylinders of infinite length, which are easier to analyze mathematically, and although Tipler suggested that a finite cylinder might produce closed timelike curves if the rotation rate were fast enough, [37]: But Hawking points out that because of his theorem, "it can't be done with positive energy density everywhere!

    I can prove that to build a finite time machine, you need negative energy. One can define geometrical quantities that measure the Lorentz boost and area increase on going round these closed null geodesics. If the causality violation developed from a noncompact initial surface, the averaged weak energy condition must be violated on the Cauchy horizon. When a signal is sent from one location and received at another location, then as long as the signal is moving at the speed of light or slower, the mathematics of simultaneity in the theory of relativity show that all reference frames agree that the transmission-event happened before the reception-event.

    When the signal travels faster than light, it is received before it is sent, in all reference frames.

    This hypothetical scenario is sometimes referred to as a tachyonic antitelephone. Quantum-mechanical phenomena such as quantum teleportation , the EPR paradox , or quantum entanglement might appear to create a mechanism that allows for faster-than-light FTL communication or time travel, and in fact some interpretations of quantum mechanics such as the Bohm interpretation presume that some information is being exchanged between particles instantaneously in order to maintain correlations between particles.

    Nevertheless, the fact that causality is preserved in quantum mechanics is a rigorous result in modern quantum field theories , and therefore modern theories do not allow for time travel or FTL communication. In any specific instance where FTL has been claimed, more detailed analysis has proven that to get a signal, some form of classical communication must also be used. A variation of Everett's many-worlds interpretation MWI of quantum mechanics provides a resolution to the grandfather paradox that involves the time traveler arriving in a different universe than the one they came from; it's been argued that since the traveler arrives in a different universe's history and not their own history, this is not "genuine" time travel.

    This concept is most often used in science-fiction, but some physicists such as David Deutsch have suggested that a time traveler should end up in a different history than the one he started from. Everett also argues that even if Deutsch's approach is correct, it would imply that any macroscopic object composed of multiple particles would be split apart when traveling back in time through a wormhole, with different particles emerging in different worlds. Certain experiments carried out give the impression of reversed causality , but fail to show it under closer examination.

    The delayed choice quantum eraser experiment performed by Marlan Scully involves pairs of entangled photons that are divided into "signal photons" and "idler photons", with the signal photons emerging from one of two locations and their position later measured as in the double-slit experiment. Depending on how the idler photon is measured, the experimenter can either learn which of the two locations the signal photon emerged from or "erase" that information. Even though the signal photons can be measured before the choice has been made about the idler photons, the choice seems to retroactively determine whether or not an interference pattern is observed when one correlates measurements of idler photons to the corresponding signal photons.

    However, since interference can only be observed after the idler photons are measured and they are correlated with the signal photons, there is no way for experimenters to tell what choice will be made in advance just by looking at the signal photons, only by gathering classical information from the entire system; thus causality is preserved. The experiment of Lijun Wang might also show causality violation since it made it possible to send packages of waves through a bulb of caesium gas in such a way that the package appeared to exit the bulb 62 nanoseconds before its entry, but a wave package is not a single well-defined object but rather a sum of multiple waves of different frequencies see Fourier analysis , and the package can appear to move faster than light or even backward in time even if none of the pure waves in the sum do so.

    This effect cannot be used to send any matter, energy, or information faster than light, [50] so this experiment is understood not to violate causality either. Nimtz told New Scientist magazine: Aephraim Steinberg, a quantum optics expert at the University of Toronto , Canada, uses the analogy of a train traveling from Chicago to New York, but dropping off train cars at each station along the way, so that the center of the train moves forward at each stop; in this way, the speed of the center of the train exceeds the speed of any of the individual cars.

    Shengwang Du claims in a peer-reviewed journal to have observed single photons' precursors , saying that they travel no faster than c in a vacuum. His experiment involved slow light as well as passing light through a vacuum. He generated two single photons , passing one through rubidium atoms that had been cooled with a laser thus slowing the light and passing one through a vacuum. Both times, apparently, the precursors preceded the photons' main bodies, and the precursor traveled at c in a vacuum. According to Du, this implies that there is no possibility of light traveling faster than c and, thus, no possibility of violating causality.

    The absence of time travelers from the future is a variation of the Fermi paradox. As the absence of extraterrestrial visitors does not prove they do not exist, so the absence of time travelers fails to prove time travel is physically impossible; it might be that time travel is physically possible but is never developed or is cautiously used.

    Carl Sagan once suggested the possibility that time travelers could be here but are disguising their existence or are not recognized as time travelers. Stephen Hawking stated that this would explain why the world has not already been overrun by "tourists from the future. Several experiments have been carried out to try to entice future humans, who might invent time travel technology, to come back and demonstrate it to people of the present time.

    Events such as Perth's Destination Day or MIT 's Time Traveler Convention heavily publicized permanent "advertisements" of a meeting time and place for future time travelers to meet. Some versions of the many-worlds interpretation can be used to suggest that future humans have traveled back in time, but have traveled back to the meeting time and place in a parallel universe. There is a great deal of observable evidence for time dilation in special relativity [57] and gravitational time dilation in general relativity, [58] [59] [60] for example in the famous and easy-to-replicate observation of atmospheric muon decay.

    Time dilation is a direct consequence of the invariance of the speed of light. This can be achieved by traveling at relativistic speeds or through the effects of gravity. For two identical clocks moving relative to each other without accelerating, each clock measures the other to be ticking slower. This is possible due to the relativity of simultaneity. However, the symmetry is broken if one clock accelerates, allowing for less proper time to pass for one clock than the other.

    The twin paradox describes this: General relativity treats the effects of acceleration and the effects of gravity as equivalent , and shows that time dilation also occurs in gravity wells , with a clock deeper in the well ticking more slowly; this effect is taken into account when calibrating the clocks on the satellites of the Global Positioning System , and it could lead to significant differences in rates of aging for observers at different distances from a large gravity well such as a black hole.

    A time machine that utilizes this principle might be, for instance, a spherical shell with a diameter of 5 meters and the mass of Jupiter. A person at its center will travel forward in time at a rate four times that of distant observers. Squeezing the mass of a large planet into such a small structure is not expected to be within humanity's technological capabilities in the near future. Philosophers have discussed the nature of time since at least the time of ancient Greece ; for example, Parmenides presented the view that time is an illusion.

    Centuries later, Isaac Newton supported the idea of absolute time , while his contemporary Gottfried Wilhelm Leibniz maintained that time is only a relation between events and it cannot be expressed independently. The latter approach eventually gave rise to the spacetime of relativity. Many philosophers have argued that relativity implies eternalism , the idea that the past and future exist in a real sense, not only as changes that occurred or will occur to the present.

    Presentism is a school of philosophy that holds that the future and the past exist only as changes that occurred or will occur to the present, and they have no real existence of their own. In this view, time travel is impossible because there is no future or past to travel to. Presentism in classical spacetime deems that only the present exists; this is not reconcilable with special relativity, shown in the following example: Alice and Bob are simultaneous observers of event O. Therefore, Alice and Bob disagree about what exists in the present, which contradicts classical presentism.

    A common objection to the idea of traveling back in time is put forth in the grandfather paradox or the argument of auto-infanticide. Some philosophers answer the paradoxes by arguing that it might be the case that backward time travel could be possible but that it would be impossible to actually change the past in any way, [78] an idea similar to the proposed Novikov self-consistency principle in physics.

    According to the philosophical theory of compossibility , what can happen, for example in the context of time travel, must be weighed against the context of everything relating to the situation. If the past is a certain way, it's not possible for it to be any other way. What can happen when a time traveler visits the past is limited to what did happen, in order to prevent logical contradictions.

    The Novikov self-consistency principle , named after Igor Dmitrievich Novikov , states that any actions taken by a time traveler or by an object that travels back in time were part of history all along, and therefore it is impossible for the time traveler to "change" history in any way.

    The time traveler's actions may be the cause of events in their own past though, which leads to the potential for circular causation , sometimes called a predestination paradox, [80] ontological paradox, [81] or bootstrap paradox. Heinlein 's story " By His Bootstraps ". The philosopher Kelley L. Ross argues in "Time Travel Paradoxes" [85] that in a scenario involving a physical object whose world-line or history forms a closed loop in time there can be a violation of the second law of thermodynamics.

    Ross uses "Somewhere in Time" as an example of such an ontological paradox, where a watch is given to a person, and 60 years later the same watch is brought back in time and given to the same character. Ross states that entropy of the watch will increase, and the watch carried back in time will be more worn with each repetition of its history.

    The second law of thermodynamics is understood by modern physicists to be a statistical law, so decreasing entropy or non-increasing entropy are not impossible, just improbable. Additionally, entropy statistically increases in systems which are isolated, so non-isolated systems, such as an object, that interact with the outside world, can become less worn and decrease in entropy, and it's possible for an object whose world-line forms a closed loop to be always in the same condition in the same point of its history.
