What was there before the big bang? Well, you see, there was no before, because before the big bang time did not exist. Time is a result of the expansion of the Universe itself. But what will happen when the Universe has finished expanding, and the movement is reversed? What will be the nature of time?

If the string-theory is correct, the Universe possesses 9 spatial dimensions, and 1 temporal dimension. Now we can imagine that in the beginning all the dimensions were twisted together. During the big bang 3 spatial dimensions, what we know as hight width, depth and 1 temporal dimension what we know as time were deployed. The other 6 remained minuscule, wound up together.

If we live in a Universe with wound up dimensions, how do we distinguish between illusion and reality?

Time as we know it is a dimension we experience only in one direction, but what if one of the additional dimentions wasn't spatial, but temporal? The smoke comes out of your cigarette, but it never goes back in. Its forever.
We cannot go back. Thats why its hard to choose; you have to make the right choice.
As long as you don't choose, everything remains possible

To what extent do our fears innate? When we hatch goose-eggs in an incubator, and then above the baby birds passes a form, simulating a goose in flight; The birds stretch their necks and call out. But if we invert the shape of the silhouette, it becomes the shape of a falcon.
The response of the baby birds is immediate, they will crouch in fear, although they have never before seen a falcon. Without any instruction, an innate fear helps them to survive. But with humans, to what ancient danger may our innate fears correspond?

>assumes nothing prior to big bang because no time.
no time =/= no existence

What is the nature of time? Does time have a nature outside of what we experience? Even if 'time' is running backwards because the universe is crunching (non sequitur), you and I would still experience the event as a continuous action in one direction of time
therefore: 'we' always go foreword within the abstract idea of time.

>If we live in a Universe with wound up dimensions, how do we distinguish between illusion and reality?
This depends on what you define to be illusion. Do you mean dream? well then flip a light switch to find out.
Do you mean a Matrix style illusion? There are philosophical arguments on both sides of this. Ultimately the answer is: good luck figuring that one out, bud. I suggest reading Hilary Putnam's Brain in a Vat.

>>what if one of the addition dimensions wasn't spatial, but temporal?
I pretty sure time, by definition, is temporal.

What happens when we fall in love? As a result of certain stimuly the brains release a powerfull discharge of endorphins. But why exactly that woman, or that man? Is there a release or odorless pheromones that corospond to a complimentary genetic signal? Or is it the physical features that we recognize; the mothers eyes, or a smell that stimulates a happy memory. Is love part of a 'plan'?
A vast war-plan between two modes of reproduction? Bacteria and viruses are asexual organisms, with each cell division (each multiplication) they mutate and perfect themselves much more quickly then we do. Against this we respond with the most fearsome weapon; sex. Two individuals, by mixing their genes, shuffle the cards and create an individual who can resist the viruses better, the more dissimilar he or she is.

String theory can be formulated in terms of an action principle, either the Nambu-Goto action or the Polyakov action, which describes how strings move through space and time. In the absence of external interactions, string dynamics are governed by tension and kinetic energy, which combine to produce oscillations. The quantum mechanics of strings implies these oscillations take on discrete vibrational modes, the spectrum of the theory.

On distance scales larger than the string radius, each oscillation mode behaves as a different species of particle, with its mass, spin and charge determined by the string's dynamics. Splitting and recombination of strings correspond to particle emission and absorption, giving rise to the interactions between particles.

I think Albert said it best, "time is only an illusion created by the conversations of the state of energy." It's rate of conversion may not be constant; but we would not be able to preserve such discongruity. (gear in a clock do not move when the watch is not wound.) To describe time as a demention is only a useful in math as a variable.

To say there was nothing before the big bang, because time dose not exists is rather flawed. time is a side effect of energy conversion. If there was energy, without conversion, you would have no time, but there would be some thing is in existence.

As for personal choice, no choice is still making a choice. You've only chosen to ignore the world around you. Take Schrödinger's cat, if you do not open the box, sooner or later the cat will be dead any way. (old age, deceases, hunger, extra) As you get older the world will become smaller. Your body will break down. The need to survive will most likely consume most of your waking life. and eventually you will die.
In short do as much as you can, as long as you can. And don't squander a limited resource.

Another possibility is that we are "stuck" in a 3+1 dimensional (i.e. three spatial dimensions plus the time dimension) subspace of the full universe. If such sub-spacetimes are exceptional sets within a larger-dimensional one, there typically exist properly localized matter and Yang-Mills gauge fields.[19] These "exceptional sets" are ubiquitous in Calabi-Yau n-folds and may be described as subspaces without local deformations, akin to a crease in a sheet of paper or a crack in a crystal, the neighborhood of which is markedly different from the exceptional subspace itself. However, until the work of Randall and Sundrum,[20] it was not known that gravity too can be properly localized to a sub-spacetime; their proof that it can made such cosmological scenarios realistic. In addition, spacetime may well be stratified, containing strata of various dimensions so that we may be inhabiting a 3+1 dimensional stratum; such geometries occur naturally in Calabi-Yau compactifications. Such sub-spacetimes are supposed to be D-branes, hence such models are known as a brane-world theories.

In either case, gravity acting in the hidden dimensions affects other non-gravitational forces such as electromagnetism. In fact, Kaluza's early work demonstrated that general relativity in five dimensions actually predicts the existence of electromagnetism. However, because of the nature of Calabi-Yau manifolds, no new forces appear from the small dimensions, but their shape has a profound effect on how the forces between the strings appear in our four-dimensional universe. In principle, therefore, it is possible to deduce the nature of those extra dimensions by requiring consistency with the standard model, but this is not yet a practical possibility. It is also possible to extract information regarding the hidden dimensions by precision tests of gravity, but so far these have only put upper limitations on the size of such hidden dimensions.

Although string theory comes from physics, some say that string theory's current untestable status means that it should be classified as more of a mathematical framework for building models as opposed to a physical theory.[33] Some go further, and say that string theory as a theory of everything is a failure.[34][35] This led to a public debate in 2007,[36][37] with one journalist expressing this opinion:
"For more than a generation, physicists have been chasing a will-o’-the-wisp called string theory. The beginning of this chase marked the end of what had been three-quarters of a century of progress. Dozens of string-theory conferences have been held, hundreds of new Ph.D.s have been minted, and thousands of papers have been written. Yet, for all this activity, not a single new testable prediction has been made, not a single theoretical puzzle has been solved. In fact, there is no theory so far—just a set of hunches and calculations suggesting that a theory might exist. And, even if it does, this theory will come in such a bewildering number of versions that it will be of no practical use: a Theory of Nothing."
—Jim Holt[38]

Mr. Nobody was a pretty good movie I have to agree OP.

But for the sake of the thread I'll post my personal opinion on the matter:

Regardless of how our "universe" works, everything ever is referred to as reality. Reality incorporates everything that exists everywhere and at every point in time, as well as anything additional that we might not have even comprehended - or that is impossible for us to comprehend.

We know we live in a space that is, to us, experienced in 3 dimensions. To us, time is not tangible, time is simply existence, and things are existING - that is, the idea of "pausing time" would be simply freezing everything in existence for as long as you "paused" time for - time still passed, everything just froze for a second. As a concept, our brain cannot fully grasp the idea of time, for we always imagine that if we were to view reality from outside of it, we would be able to watch it at the speed we pleased, but there would always be a point in time of which to look at and you would view all dimensions at that point in time - the idea of seeing all dimensions at all points in time is incomprehensible to us because well...it doesn't make any sense.

But: In my view of the world, our universe is an event. That is, from the moment our universe had the big bang until it will have the big crunch, all of that is some form of something at a higher level that happens not on a scale of time but is simply THERE. That is, if you were to look at that higher level, everything would be unchanging. At some "place" in that higher level, our universe - all points in time and all dimensions - would be there, and by looking at it it would be an unmoving, unchanging object. Simply there - you wouldn't see time passing, you would simply see everything.

iunno, it's hard for me to imagine time passing at the highest level of existence really.

By gradual but constant changes influenced by adaptive pressures in their environment that cause physical modifications to persist if they are advantageous.

Can you specify the kind of gradual change you’re referring to?

In any population of plants or animals, over time random genetic mutations will occur. Most will be detrimental, some will have a neutral effect, and some will confer a selective advantage, however small or seemingly inconsequential it might appear.
