We can label some views on the first question asfollows. Eternalism is the view that past and future times,objects and events are just as real as the present time and presentevents and objects. Nowism is the view that only the presenttime and present events and objects exist. Now-and-then-ismis the view that the past and present exist but the future doesnot. We can also label some views on the secondquestion. The A-theory answers in the affirmative: the flowof time and division of events into past (before now), present (now)and future (after now) are objective features of reality (as opposedto mere features of our experience). Furthermore, they are linked: theobjective flow of time arises from the movement, through time, of theobjective now (from the past towards thefuture). The B-theory answers in the negative: while wecertainly experience now as special, and time as flowing, the B-theory denies that what is going on here is that we are detectingobjective features of reality in a way that corresponds transparentlyto how those features are in themselves. The flow of time and the noware not objective features of reality; they are merely features of ourexperience. By combining answers to our first and second questions wearrive at positions on the metaphysics of time suchas:[]

So what about those ethics of travel

One objection to the possibility of time travel flows directly fromattempts to define it in anything like Lewis's way. The worry isthat because time travel involves “a discrepancy between timeand time”, time travel scenarios are simply incoherent. The timetraveller traverses thirty years in one year; she is 51 years old 21years after her birth; she dies at the age of 90, 200 years before herbirth; and so on. The objection is that these are straightforwardcontradictions: the basic description of what time travel involves isinconsistent; therefore time travel is logicallyimpossible.[]

The Prophet Amos (5:21-24) echoed the sentiments of Isaiah in God’s revulsion at the hypocrisy and incongruity of acts of religious worship with the persistence of pervasive social injustice:

The Ethics of Budget Travel: ..

There must be something wrong with this objection, because it wouldshow Einstein to be logically impossible—whereas thissort of future-directed time travel has actually been observed (albeiton a much smaller scale—but that does not affect the presentpoint) (Hafele and Keating, 1972b,a). The most common response to theobjection is that there is no contradiction because the interval oftime traversed by the time traveller and the duration of her journeyare measured with respect to different frames of reference: there isthus no reason why they should coincide. A similar point applies tothe discrepancy between the time elapsed since the timetraveller's birth and her age upon arrival. There is no more ofa contradiction here than in the fact that Melbourne is both 800kilometres away from Sydney—along the main highway—and1200 kilometres away—along the coastroad.[]

Before leaving the question ‘What is time travel?’ weshould note the crucial distinction between changing the past andparticipating in (aka affecting or influencing) thepast.[] In thepopular imagination, backwards time travel would allow one to changethe past: to right the wrongs of history, to prevent one'syounger self doing things one later regretted, and so on. In a modelwith a single past, however, this idea is incoherent: the verydescription of the case involves a contradiction (e.g. the timetraveller burns all her diaries at midnight on her fortieth birthdayin 1976, and does not burn all her diaries at midnight on her fortiethbirthday in 1976). It is not as if there are two versions of the past:the original one, without the time traveller present, and then asecond version, with the time traveller playing a role. There is justone past—and two perspectives on it: the perspective ofthe younger self, and the perspective of the older time travellingself. If these perspectives are inconsistent (e.g. an event occurs inone but not the other) then the time travel scenario isincoherent.
