Absolute theories of time:
The view that time exists independently of things and that time would pass or occur even if nothing was happening in the universe.
Flow theory of time:
The view that time is in motion. That moments of time, like water in a river, flow from the varyingly distant future into the present then recede into the more and more distant past.
Incompatible:
Two claims are said to be incompatible when it is not possible for both of them to be simultaneously true though they could both be simultaneously false. For example, if I say today is Tuesday and you say it is Thursday, we cannot both be correct though we could both be wrong. Hense our two claims are incompatible.
Metaphysics:
The philosophical study of the ultimate nature of reality.
Newton physics:
Typically having to do with the theories of motion and universal gravitation described by Issac Newton.
Paradox:
When two apparently justified beliefs are seen to be incompatible or inconsistent.
Relational theories of time:
The view that time could not exist independently of the existence of changing things and thus time should be conceived of as a kind of dimension of changing things.
Enisteins’s relativity theories:
- Special Theory of Relativity:
Concerns space/time and the claim that all of the laws of physics are equally valid in all nonaccelerated frames of reference; light has a constant speed and these have the consequences that the mass of an object increases as it approaches the speed of light and time slows in reference to other frames of references.
Enisteins’s relativity theories:
- General theory of relativity:
an extension of the special theory of relativity to a geometric theory of gravitation with the principle that gravitational and inertial forces are equivalent.
Enisteins’s relativity theories:
- Twin paradox:
Generated from the special theory of relativity in which twins are no longer the same age. The different ages of twins result from on twin traveling away from earth at a highly accelerated speed. Since this accelerated and thus different reference frame, according to theory, will have time slow in relationship to the reference frames of earth, the traveling twin will age slower than the earth twin.
Aristotle-
found the existence of the present difficult since the present is a part of the future and the past which do not exist.
J.M.E. McTaggert-
stated time is unreal. No event could be said to be past, present, and future since these properties are incompatible.
Kant-
his view is that time is a mind-dependent intuition
St. Augustine-
understanding of the nature of time is “I don’t know” Present instant of time is the only part of time that is real.
Einstein-
Special Theory of relativity. Seemed to prove that as one approaches the speed of light time slows relative to another, slower, frame of reference. “the distinction between past, present, and future is only an illusion.”
Henri Bergson-
time flow as moving from future through present and into the past.
Why does Einstein say that "Now" has no objective meaning?
Einstein said that “Now” has no objective meaning because time the distinction between, past, present, and future in itself is an illusion. Because he stated you have to accept the idea that subjective time with its emphasis on the now has no objective meaning.
The textbook talks about "objective" and "subjective" time. Discuss what you think
that means and any implications that might flow from it.
Objective time means that process of time existing independently to us as individuals. Subjective time is time that we have keep account of in our minds or ideas.
J.J.C. Smart -
stated our experience of time as passing is an illusion.
The textbook talks about "objective" and "subjective" time. Discuss what you think that means and any implications that might flow from it.
Objective time means that process of time existing independently to us as individuals. Subjective time is time that we have keep account of in our minds or ideas.

The implication that might flow from it are is time really real in the sense of calculating it by numbers and clocks to be more precise or can it be measured by what we observe around us which would be the vague sense or the objective sense. Time in itself can not be defined when spoken out load. If you really get in depth to what time is you can define it in the sense of your thoughts. But when spoken out load the definition of what is time can be disputed as to is it real or is it an illusion. To me time is simply a measurement we use to maintin order and communicate with each other.
