In summary, this paper looks at various models of how time is perceivable and discusses the pros and cons of each. It is potentially useful for people who still believe in a complete break at the big bang, as it lists a variety of different models.

Great Paper with some general calrifications on how Time is perceived in various models:http://uk.arxiv.org/abs/physics/0408111

Hi Olias, I saw your post earlier and then lost track of it, just found it again.

since this is Rudi Vaas, who is a good science journalist as well as a philosophy/history of science expert, I will put a link to some of his popular articles in case newcomers haven't seen them (most regulars have I would guess)

Beyond Space And Time
Rudi Vaas
7 pages, English translation of "Jenseits von Raum und Zeit"

The Duel: Strings versus Loops
Rudi Vaas
10 pages, English translation of "Das Duell: Strings gegen Schleifen"

The Inverted Big-Bang
Rudi Vaas
8 pages, English translation of "Der umgestuelpte Urknall"

Olias what I see in this article Time before Time
is it is good for having no formulas
(accessible to completely un-mathematical people)
and it gives a historical perspective on the different ways
people have viewed the universe

and then in addition it looks at the modern view of the Big Bang
as not having necessarily been a singularity
but (since the pivotal 2001 paper) time stretching back before where the break used to be.

It is potentially a useful paper because there are still people
who imagine a complete break at bang-time and having
papers like this can help them get over it.

however the writing is not as popular or fun as in the other Rudi Vaas
articles I've seen. it is even a bit Respektable as one might imagine from its being based on a lecture given in Austria at the
"26th International Wittgenstein Symposium"
You just don't go into a room full of German philosophy academics and tell them the bang was a bounce and time didnt start then. It has to be approached by listing a whole taxonomy of different possibilities from Demokritus and Plato onwards. Rudi obvously enjoys the company of the Potsdam Loop crowd but he does what he has to do to get his message to the Philosophers.
 

FAQ: Time Before Time: Physics Paper Clarifications

What is the concept of "Time Before Time" in physics?

The concept of "Time Before Time" in physics refers to the period before the Big Bang, which is considered to be the beginning of our universe. This is a theoretical concept that is still being studied and researched by scientists.

How do scientists measure time in the early universe?

Scientists use various methods to measure time in the early universe, such as studying cosmic background radiation and analyzing the redshift of distant objects. These methods are based on the principles of general relativity and the expansion of the universe.

Can we accurately determine the exact time of the Big Bang?

No, it is not possible to accurately determine the exact time of the Big Bang. This is because time itself began with the Big Bang, so there is no "before" or "after" for us to measure. However, scientists can estimate the age of the universe by measuring the cosmic microwave background radiation.

Is it possible for time to run backwards in the early universe?

The laws of physics suggest that time can only move forward, and it is not possible for time to run backwards. While there are some theoretical models that suggest the possibility of a "Big Crunch" where the universe collapses and time reverses, there is currently no evidence to support this idea.

What are the implications of understanding time in the early universe?

Studying time in the early universe can help us better understand the origins of our universe and the fundamental principles of physics. It can also give us insights into the evolution of the universe and potentially lead to new theories and discoveries in cosmology.
