Preface
Before I begin I would like to make a few points. First, Space and Time are
different in many ways, but they do relate to each other and ,in a way, rely
on each other. Time is quite difficult to explain and so is space…not
because it is hard to comprehend but on the contrary, the only problem is
that there are so MANY theories on it that you can’t really get a “Good”
definition of either. Time and Space really are how YOU comprehend it to
be. So with that said, please enjoy the presentation.

What is Time?
Time is known as many things, one is “Einstein’s Unfinished Revolution”
some questions that vex us is, What causes time? Why time slows in
gravity? Why time slows in motion? Is time a dimension? All
unanswered questions and all that NEED answers, there are a few
theories, well many to be exact, but few good ones.
John Ellis McTaggart observed that historical evens
have the same time characteristics as fictional stories.
Ex. Fictional and historical events have the earlier
then the later, and the past the present and the
future. Meaning the past is more like a memory of
events and being more of and imagination.
Other people believe time is an infinitesimal. Meaning, the present may
be an mental awareness of the recording in our brain, but say a person
falls asleep during an event. They miss it completely and basically, that
event does not exist in that persons past. Unless we can be consciously
aware of an event it does not enter into our past memory, this also
appeals to when we get lost in thought so to speak. As for the future, it
is an projection, so to speak, of our past experiences in our memories.
Some believe time is an emergent concept, which is, the process of
motion and forces from which time emerges however what we consider
to be time is an illusion. Our memory creates the illusion of the past.
Conscious perception of events gives us the feeling of the present, the
future is a mental construct patterned on memory experience of the
past, concept of time emerges as our mind tries to make sense of the
world around us that is constantly changing. Others believe time Is an
illusion that suggests that only the present is real. (A, B, C analysis of
time –John Ellis McTaggart) future events move into the present to
move into the past and then moves further into the past.
The measurement of time is quite simple, and is usually very easy
to identify in every language. The time of day is measured by the
position of the sun, and the months/years are the orbit of the
earth around the sun (seasons).

So, what exactly is time?
Time is the presence of motion and forces and is caused by
the expansion of space, in short that is. Another way of saying
it, is that time is what you yourself feel what time is to be.
Whether it be just another day tomorrow or a the second
hand moving on the clock. It is what you percept it to be and
whatever your imagination and thought brings it to be.
“Procrastination is the thief of
time.”
-Edward Young
What is space?
Gottfried Leibniz, the German philosopher-mathematician,
and Isaac Newton, the English physicist-mathematician, set
out two opposing theories of what space is. They decided
that space is no more than the collection of spatial relations
between objects in the world,"space is that which results
from places taken together".
According to “The Principle of Sufficient
Reason”, any theory of space that implied that
there could be these two possible universes,
must be wrong.
Newton took space to be more than relations between
material objects and based his position on observation and
experimentation. In 1905, Albert Einstein published a paper
on a special theory of relativity, in which he suggested that
space and time be combined into a single construct known as
“Spacetime”.
Over the following ten years Einstein worked on a
general theory of relativity, which is a theory of how
gravity interacts with “Spacetime”. Instead of viewing
gravity as a force field acting in “Spacetime”, Einstein
suggested that it modifies the geometric structure of
“Spacetime” itself.
According to the general theory, time goes more
slowly at places with lower gravitational potentials
and rays of light bend in the presence of a
gravitational field.
Immanuel Kant described space and time as elements
of a systematic framework that humans use to
structure their experience. Ultimately, space is best
described as the continuous extension in all directions
in which all matter exists
“Space is big. You just won't believe how vastly, hugely, mindbogglingly big it is. I mean, you may think it's a long way down
the road to the drug store, but that's just peanuts to space.”
-Douglas Adams
