The Dominion War is an extended plot concept developed in several story arcs of Star Trek: Deep Space Nine, an American science-fiction television series produced by Paramount Pictures.In the fictional Star Trek universe, the Dominion War is a conflict between the forces of the Dominion, Cardassian Union and, later, the Breen Confederacy against the Alpha Quadrant alliance of the United.

Time dilation explains why two working clocks will report different times after different accelerations. For example, at the time goes slower, lagging 0.007 seconds behind for every six months. For satellites to work, they must adjust for similar bending of to coordinate with systems on Earth.Time dilation is a difference in the elapsed measured by two clocks, either due to them having a velocity relative to each other, or by there being a difference between their locations. After compensating for varying signal delays due to the changing distance between an and a moving clock (i.e.
), the observer will measure the moving clock as ticking slower than a clock that is at rest in the observer's own. A clock that is close to a massive body (and which therefore is at lower gravitational potential) will record less elapsed time than a clock situated further from the said massive body (and which is at a higher gravitational potential).These predictions of the have been repeatedly confirmed by experiment, and they are of practical concern, for instance in the operation of systems such as. Time dilation has also been the subject of science fiction works, as it technically provides the means for forward. From the local frame of reference of the blue clock, the red clock, being in motion, is perceived as ticking slower (Exaggerated)indicates that, for an observer in an, a clock that is moving relative to him will be measured to tick slower than a clock that is at rest in his frame of reference. This case is sometimes called special relativistic time dilation. The faster the, the greater the time dilation between one another, with the rate of time reaching zero as one approaches the (299,792,458 m/s). This causes that travel at the speed of light to be unaffected by the passage of time.Theoretically, time dilation would make it possible for passengers in a fast-moving vehicle to advance further into the future in a short period of their own time.
For sufficiently high speeds, the effect is dramatic. For example, one year of travel might correspond to ten years on Earth. Indeed, a constant 1 acceleration would permit humans to travel through in one human lifetime.With current technology severely limiting the velocity of space travel, however, the differences experienced in practice are minuscule: after 6 months on the (ISS) (which orbits Earth at a speed of about 7,700 m/s ) an astronaut would have aged about 0.007 seconds less than those on Earth. The cosmonauts and both experienced time dilation of about 20 milliseconds compared to time that passed on Earth. Simple inference of velocity time dilation.
The blue dots represent a pulse of light. Each pair of dots with light 'bouncing' between them is a clock.
For each group of clocks, the other group appears to be ticking more slowly, because the moving clock's light pulse has to travel a larger distance than the stationary clock's light pulse. Main article:. A comparison of lifetimes at different speeds is possible. In the laboratory, slow muons are produced; and in the atmosphere, very fast moving muons are introduced by cosmic rays.

Taking the muon lifetime at rest as the laboratory value of 2.197 μs, the lifetime of a cosmic ray produced muon traveling at 98% of the speed of light is about five times longer, in agreement with observations. An example is Rossi and Hall (1941), who compared the population of cosmic-ray-produced at the top of a mountain to that observed at sea level. The lifetime of particles produced in particle accelerators appears longer due to time dilation. In such experiments the 'clock' is the time taken by processes leading to muon decay, and these processes take place in the moving muon at its own 'clock rate', which is much slower than the laboratory clock. This is routinely taken into account in particle physics, and many dedicated measurements have been performed. For instance, in the muon storage ring at CERN the lifetime of muons circulating with γ = 29.327 was found to be dilated to 64.378 μs, confirming time dilation to an accuracy of 0.9 ± 0.4 parts per thousand.Proper time and Minkowski diagram.
One twin has to change frames, leading to different in the twin's world lines.In the from the first image on the right, clock C resting in inertial frame S′ meets clock A at d and clock B at f (both resting in S). All three clocks simultaneously start to tick in S. The worldline of A is the ct-axis, the worldline of B intersecting f is parallel to the ct-axis, and the worldline of C is the ct′-axis. All events simultaneous with d in S are on the x-axis, in S′ on the x′-axis.The between two events is indicated by a clock present at both events. It is invariant, i.e., in all inertial frames it is agreed that this time is indicated by that clock.
Interval df is therefore the proper time of clock C, and is shorter with respect to the coordinate times ef=dg of clocks B and A in S. Conversely, also proper time ef of B is shorter with respect to time if in S′, because event e was measured in S′ already at time i due to relativity of simultaneity, long before C started to tick.From that it can be seen, that the proper time between two events indicated by an unaccelerated clock present at both events, compared with the synchronized coordinate time measured in all other inertial frames, is always the minimal time interval between those events. However, the interval between two events can also correspond to the proper time of accelerated clocks present at both events.
Under all possible proper times between two events, the proper time of the unaccelerated clock is maximal, which is the solution to the. Derivation and formulation. Time passes more quickly further from a center of gravity, as is witnessed with massive objects (like the Earth)Gravitational time dilation is experienced by an observer that, at a certain altitude within a gravitational potential well, finds that his local clocks measure less elapsed time than identical clocks situated at higher altitude (and which are therefore at higher gravitational potential).Gravitational time dilation is at play e.g. Yohjo simulator download. For ISS astronauts. While the astronauts' slows down their time, the reduced gravitational influence at their location speeds it up, although at a lesser degree. Also, a climber's time is theoretically passing slightly faster at the top of a mountain compared to people at sea level.

It has also been calculated that due to time dilation, the is 2.5 years younger than the. 'A clock used to time a full rotation of the earth will measure the day to be approximately an extra 10 ns/day longer for every km of altitude above the reference geoid.' Travel to regions of space where extreme gravitational time dilation is taking place, such as near a, could yield time-shifting results analogous to those of near-lightspeed space travel.Contrarily to velocity time dilation, in which both observers measure the other as aging slower (a reciprocal effect), gravitational time dilation is not reciprocal. This means that with gravitational time dilation both observers agree that the clock nearer the center of the gravitational field is slower in rate, and they agree on the ratio of the difference.Experimental testing. Main article:. In 1959 and measured the very slight in the frequency of light emitted at a lower height, where Earth's gravitational field is relatively more intense.
The results were within 10% of the predictions of general relativity. In 1964, Pound and J. Snider measured a result within 1% of the value predicted by gravitational time dilation. (See ). In 2010 gravitational time dilation was measured at the earth's surface with a height difference of only one meter, using optical atomic clocks.Combined effect of velocity and gravitational time dilation.
