You then return to the gallery and notice other pictures from the renaissance,
Another trip and you notice the floor is carpet and the ceiling is white. another trip and you modern art on the other walls...and so on. We have different experiences of it, but the room and all thats in it is always there.
Its our experiencing the different aspects of the room that makes us experience time. And so..... we come in and out we experience time through different moments, different things, but the 'room' was always there.
The most starightforward conculsion is that past and future are indeed fixed, for this reason Physicists prefer to see time as laid out in its entirety, a time scape.....with all past and future events located there together
Neither scientists nor Philosphers really know what time is or why it exists. The best thing they can say is it is akin (but not identical to) space. For example the 2 dimensional orbit of the moon through space can be thought of as a 3 dimensional corkscrew through time and space
With the movement of time, Relative to what does it move? Other types of motion relate one physical process to another, the putative flow of time relates to only time itself, Posing the simple question, "how does time pass?"
The Fact that time can be treated as a fourth dimension does not mean it is identical to the 3 dimensions of space. Time and Space enter into expierience and physical theory in distinct ways. For example to formula for calcualting space time distances is not the same as calculatng spacial distances.
THE DISTINCTION BETWEEN SPACE TIME UNDERPINS THE KEY NOTION OF CAUSALITY, STOPPING CAUSE AND EFFECT FROM BEING HOPELESSLY JUMBLED.
On the ther hand other physicists believe on the smallest scale of size and duration, space and time may lose their seperate identities
One of the main motivations for SUSY comes from the quadratically divergent contributions to the Higgs mass squared. The quantum mechanical interactions of the Higgs boson causes a large renormalization of the Higgs mass and unless there is an accidental cancellation, the natural size of the Higgs mass is the highest scale possible. This problem is known as the hierarchy problem. Supersymmetry reduces the size of the quantum corrections by having automatic cancellations between fermionic and bosonic Higgs interactions. If supersymmetry is restored at the weak scale, then the Higgs mass is related to supersymmetry breaking which can be induced from small non-perturbative effects explaining the vastly different scales in the weak interactions and gravitational interactions. In many supersymmetric Standard Models there is a heavy stable particle (such as neutralino) which could serve as a WIMPs (weakly interacting massive particles) dark matter candidate. The existence of a supersymmetric dark matter candidate is closely tied to R-parity.

What direction is time taking us? We call it 'the future'... but is it really? Is 'the future' an abstract term? A concept that allows our brain to deal with extra dimensions outside of our 3 dimensional framework? Could the future be defined as simply 'somewhere'? Given we have never been to the future, can we reliably say that that is where we are traveling?...
and if so...
Is the future brought towards us or are we propelled into it? Do we move along with time like floating down a river... or are we stationary with time thrust upon us... kind of like facing into a head wind?
Would we not perceive it the same way in either circumstance?
Where does time come from? Is there a point from where it flows? Does it still flow once it's 'behind us'... or is it something transient that only exists in the 'now'? Does it even exist.. or does 'stuff' just happen in a static space propelled by some other 'force' we cannot even fathom?
