is usually a special hypothetical
in which the laws of physics might appear to be identifiably
different (simpler) from those in other frames. In theories that apply the
principle of relativity to inertial motion, physics is the same in all
inertial frames, and is even the same in all frames under the general
principle of relativity.
Inertial Frame of Reference
is a frame of reference in which bodies,
whose net force acting upon them is zero, are not accelerated; that is
they are at rest or they move at a constant velocity in a straight line.
In analytical terms, it is a frame of reference that describes time and
space homogeneously, isotropically, and in a time-independent manner.
Conceptually, in classical physics and special relativity, the physics of
a system in an inertial frame have no causes external to the system. An
inertial frame of reference may also be called an inertial reference
frame, inertial frame, Galilean reference frame, or inertial space. All
inertial frames are in a state of constant, rectilinear motion with
respect to one another; an accelerometer moving with any of them would
detect zero acceleration. Measurements in one inertial frame can be
converted to measurements in another by a simple transformation (the
Galilean transformation in Newtonian physics and the Lorentz
transformation in special relativity). In general relativity, in any
region small enough for the curvature of spacetime and tidal forces to be
negligible, one can find a set of inertial frames that approximately
describe that region. In a non-inertial reference frame in classical
physics and special relativity, the physics of a system vary depending on
the acceleration of that frame with respect to an inertial frame, and the
usual physical forces must be supplemented by fictitious forces. In
contrast, systems in non-inertial frames in general relativity don't have
external causes, because of the principle of geodesic motion. In classical
physics, for example, a ball dropped towards the ground does not go
exactly straight down because the Earth is rotating, which means the frame
of reference of an observer on Earth is not inertial. The physics must
account for the Coriolis effect
this case thought of as a force—to predict the horizontal motion. Another
example of such a fictitious force associated with rotating reference
frames is the centrifugal effect, or centrifugal force.

creates what we perceive
as a temporal dimension where resting mass is
always trying to catch up to the speed of light. The gap between the 2
types of energy is called 3D space
. Time slows the faster you move until
the point when you get to the speed of light (c) and time stops. It no
longer moves forward or backward. This is time dilation
and helps prove
this is true. Because stuff with resting mass can never catch up the
process is ongoing and fast moving energy continues to speed away in all
directions, creating more space. This also explains the arrow of time

Philosophy of Space and Time
is the branch of
concerned with the
issues surrounding the ontology
character of space and time. While such ideas have been central to
philosophy from its inception, the philosophy of space and time was both
an inspiration for and a central aspect of early analytic philosophy. The
subject focuses on a number of basic issues, including whether time and
space exist independently of the mind, whether they exist independently of
one another, what accounts for time's apparently unidirectional flow,
whether times other than the present moment exist, and questions about the
nature of identity (particularly the nature of identity over time).

Time relates to
motion of matter within space. Take away the matter, and there are no
properties for time to measure, or time relative to the matter. The space
may be infinite and may exist whether or not matter existed within it.
Time and space may be already separate, as time itself is merely a
concept to measure distance between between material objects and their
related velocities. Concepts of space and time are linked by common
dependence on the existence of objects. Every object is also a concept
that is scale dependent with arbitrarily defined boundaries in both space
and time. But every concept only has meaning
in relation to all other concepts
. No concept stands on it own. It is
impossible also to think of a single thing as an object without a subject
or a subject without an object. There two types of time, universal time
which runs as a backdrop to everything which as yet we do not understand
fully. Then relative time
which man instigated and uses. Objects in space
are described as three dimensional and can be measured, relative to their
height, width and depth.

Zeno's Arrow Paradox
. If everything when it occupies an equal space is
at rest, and if that which is in
is always occupying such a
space at any moment, the flying arrow is therefore motionless. (as
recounted by Aristotle, Physics VI:9, 239b5). In the arrow
known as the fletcher's paradox), Zeno states that for motion to occur, an
object must change the position which it occupies. He gives an example of
. He states that in any one (duration-less) instant of
is neither moving to where it is, nor to where it is not.
It cannot move to where it is not, because no time elapses for it to move
there; it cannot move to where it is, because it is already there. In
other words, at every instant of time there is no motion occurring. If
everything is motionless at every instant, and
time is entirely composed
, then motion
is impossible. Whereas the first two paradoxes
divide space, this paradox starts by dividing time—and not into segments,
but into points. Paradox of Place From Aristotle:
If everything that exists has a place, place too will have a place, and so
on ad infinitum.

some of the things that you think you know, are actually wrong and not

learning is or did you have access to the most valuable knowledge and

A lot of people said that if they
had a chance to travel back in time they would kill Hitler. But if you
were intelligent, you would go back in time to educate Hitler instead
of killing him. Then he could have educated others. So by time that you
are born, all the problems in the world would be solved. So that means
that every person alive has the ability to time travel, they just have to
choose the time they want to live in and understand that everything
that they do now will affect their future self. But the reality is, it's
not just you who gets affected by your past actions, it's everyone else
and everything else that gets affected by your past actions.

Eternalism in philosophy of time
is a philosophical approach to the
ontological nature of time, which takes the view that all existence in
time is equally real, as opposed to presentism or the growing block
universe theory of time, in which at least the future is not the same as
any other time. Some forms of eternalism give time a similar ontology to
that of space, as a dimension, with different times being as real as
different places, and future events are "already there" in the same sense
other places are already there, and that there is no objective flow of
time. It is sometimes referred to as the "block time" or "block universe"
theory due to its description of space-time as an unchanging
four-dimensional "block", as opposed to the view of the world as a
three-dimensional space modulated by the passage of time.

repeated and re-experienced by the characters, and there is often some
hope of breaking out of the cycle of repetition. Time loop is sometimes
used to refer to a causal loop; although they appear similar, causal loops
are unchanging and self-originating, whereas time loops are constantly
resetting: when a certain condition is met, such as a death of a character

characters retaining the memories from the previous loop. Stories with
time loops commonly center on the character learning from each successive

moving relative to an observer will be measured to tick slower than a
clock that is at rest in the observer's own
. A clock that is under the influence of a stronger
gravitational field than an observer's will also be measured to tick
slower than the observer's own clock. Such time dilation has been
repeatedly demonstrated, for instance by small disparities in a pair of
atomic clocks after one of them is sent on a space trip, or by clocks on
the Space Shuttle running slightly slower than reference clocks on Earth,
or clocks on GPS and Galileo satellites running slightly faster. Time
dilation has also been the subject of science fiction works, as it
technically provides the means for forward time travel.
Time Passes Quicker at a Higher Altitudes
Gravitational Time Dilation
is a form of time dilation, an actual
difference of elapsed time between two events as measured by observers
situated at varying distances from a
. The higher the gravitational potential (the farther
the clock is from the source of gravitation), the faster time passes.
Albert Einstein originally predicted this effect in his theory of
relativity and it has since been confirmed by tests of general relativity.

to the brain appears to be extended in time. For example, chronostasis
temporarily occurs when fixating on a target stimulus, immediately
following a saccade (i.e., quick eye movement). This elicits an
overestimation in the temporal duration for which that target stimulus
(i.e., postsaccadic stimulus) was perceived. This effect can extend
apparent durations by up to 500 ms and is consistent with the idea that

Duration in philosophy
is a theory of time and
that the moment
one attempted to measure a moment, it would be gone: one measures an
immobile, complete line, whereas time is mobile and incomplete. For the
individual, time may speed up or slow down, whereas, for science, it would
remain the same. Hence Bergson decided to explore the inner life of man,
which is a kind of duration, neither a unity nor a quantitative
multiplicity. Duration is ineffable and can only be shown indirectly
through images that can never reveal a complete picture. It can only be
grasped through a simple intuition of the imagination.

is a clock that depends for its accuracy on another clock, a
master clock. Many modern clocks are synchronized, either through the
Internet or by radio time signals, to a worldwide time standard called
Coordinated Universal Time (UTC) based on a network of master atomic
clocks in many countries.Europe's standard

is the nominal frequency of the oscillations of alternating
current (AC) in an electric power grid transmitted from a power station to
the end-user. In large parts of the world this is 50 Hz, although in the
Americas and parts of Asia it is typically 60 Hz. Current usage by country
or region is given in the list of mains power around the world. During the
development of commercial electric power systems in the late 19th and
early 20th centuries, many different frequencies (and voltages) had been
used. Large investment in equipment at one frequency made standardization
a slow process. However, as of the turn of the 21st century, places that
now use the 50 Hz frequency tend to use 220–240 V, and those that now use
60 Hz tend to use 100–127 V. Both frequencies coexist today (Japan uses
both) with no great technical reason to prefer one over the other and no
apparent desire for complete worldwide standardization. Unless specified
by the manufacturer to operate on both 50 and 60 Hz, appliances may not
operate efficiently or even safely if used on anything other than the
intended frequency. In practice, the exact frequency of the grid varies
around the nominal frequency, reducing when the grid is heavily loaded,
and speeding up when lightly loaded. However, most utilities will adjust
the frequency of the grid over the course of the day to ensure a constant
number of cycles occur. This is used by some clocks to accurately maintain
their time. (also known as power line frequency in American English or
mains frequency in British English).

Daylight Saving Time
is the practice of advancing clocks
during summer months by one hour so that evening daylight lasts an hour
longer, while sacrificing normal sunrise times. Typically, regions with
summer time adjust clocks forward one hour close to the start of spring
and adjust them backward in the autumn to standard time.

need it for? And do the reasons out weigh the adverse effects.

"We have all had moments where we have helped someone in need, maybe
saving someone's life, and we remember how great we felt because
we know we did something that was needed, something that was
special, because we know how important help can be to someone in
need. I'm in one of those moments right now, except this is one
big moment, a much larger picture, a moment stretching many
lifetimes and encompassing many moments in time,
Except this type of time is not measured by our sun, this time stretches
across the universe. Time on earth has been slowed down, giving humans a
chance to see and experience life in a unique way. But our experience of
time is only unique to earth. Beyond our planet time takes on a whole new
meaning where time is not measured in seconds, hours, days or years, in
fact it's not a measurement at all, time is something that is felt and
experienced, which transcends all definitions of time and our
understanding of what time is. It is the ultimate moment."
