Jimmy :

Ask Paul Davies! (He lectures at Adelaide Uni and is also a Dr wHo fan - and he writes a lot about this topic)

I used to be really into these ideas - but I've not read any of my cosmolgy books for about 5 years, and have seemed to forgot a lot of it.

From what I can remember, I think we need to capture the energy within a singularity, and develop a wormhole so that we can come out of the particle dispersion without being completely 'spaghettified'.
At least that's what they say in Dr Who, Event Horizon, and popular science/cosmology books written by Paul Davies, John Gribbin, John Wheeler and Stephen Hawking.


Thanks, Jimmy, for the lead.
Just downloaded an article of interviews with the guy.I think it will keep me busy for a while!
Typical case of some questions answered, many more raised.
Fantastic!!!

We can speculate all we want, but science - and I mean testing hypotheses and gaining data - will be the only way such a possibility will be achieved.
Rather than come out with wild ideas and speculations, I think it's better to just leave these topics to the experts. They have empirical and authoritive knowledge on the subject - and they are the ones that do all the hard work that make the dreams of we ordinary folk possible.

Just going on about wild fancies is a load of wank that belongs in the new age section of pop culture multinational bookshops, alongside texts on astrology and the occult.
(Topics that have no scientific validity - they have no empirical evidence and cannot withstand any falsification or logic tests)

Going on about things by using a priori statements that cannot be backed up with any form of deductive logic means that you're not saying anything that can be substantiated with careful research, analysis or data.
Really this is just wanking, Terry. (no offence intended, mate)

To seriously consider these matters, one must begin by achieving a PhD in astrophysics and then dedicate their time and energy into research and analysis of countless equations and theroems using both abstract reasoning and the scrutiny of endless data. That's why I don't even bother considering such things!

Albert Einstein, Stephen Hawking,Wernher von Braun, Neils Bohr, Max Planck, John Wheeler et. al. worked like slaves to make the advances in science and technology that we have today. Those that will give us tomorrow's achievements are locked away in research centres and wouldn't have a care for anything found in popular science texts.

I think you're being too harsh here. While science is a marvelous tool it relies on hapstance, falsifiablity and most of all informed steering by philosophers. Remember when ABC's Catalyst did a piece on Intelligent Design they interviewed a scientist, an IDer and then a philosopher to get perspective.

Science is nothing but the physical arm of philosophy gone professional, and even so what it is is entirely defined by philosophy of science. Since falsification has become the hallmark of science (because Karl Popper articulated it), it has some profound implications for truth and scepticism in the lab and outside.

So all claims should be treated with scepticism, especially scientific ones. This is why I recommend investigating alternatives to the dominant paradigm, all too often we can learn as much from the mistakes as the accepted triumphs.

You seem to forget the capacity for serendipity (The facility of making happy chance discoveries - Horace Walpole).

Quite a few inventions/discoveries have been made purely by chance, with the added chance that someone observed it happening and came up with a theory about it.  Think Newton & apple.

An Apochryphal Tale

As the old man lay on his deathbed, his wife summoned for the Doctor.
Eventually there was a knock on the door and the Doctor was admitted.
The old lady led him to her husband. The Doctor tut-tutted, felt for a pulse, then a heart-beat and finally held a mirror to the old mans mouth.
"I`m afraid your husband is dead", announced the Doctor in a grave tone.
"I`ve not gone yet", whispered the old man.
"Be Quiet", snapped his wife, embarrased.
"The Doctor knows what he`s doing"!

Jimmy; if you want to put yourself in the hands of self appointed `experts` then that is your decision, but please don`t rail against those of us who do not share your faith.
By the way, no offence taken. Quite the opposite. I`m glad that someone has strong feelings either way about the subject AND is prepared to reply.

Medical science alone has given us thalidomide, DDT and the tobacco companies purring "no proven link". But science then goes on to correct all these.
If I got sick I'd go to a doctor, even a quack, rather than a healer.

Serendipity is cited in my post under its nom de plume as hapstance.

Can we then presume that you don`t believe in the concept that something is "written in the stars ?"

You mean me? OK...
Pre-destiny or determinism vs free will. Chaos Theory has profound implications for determinism; it implies the theory is dead in the water! However I'm happy to be Devil's Advocate...
There is a compatability between the theoris which states that it may be possible to incoporate free will as part of a pre-destined reality!

Actually I was joking about the "written in the stars" bit but, as usual, I can see you are a deep thinker.
Can I ask; is Chaos theory in any way related to quantum theory ?

if there is chaos theory is there also a chaos practical.

Quantum theory relates to the smallest possible or indivisible nature of reality (and could equally be called atom theory than quanta); chaos theory to the unpredictable. There is a crossover in describing the small scale structure of the universe, but not really beyond this.
But then again it sounds like the jumping off point to an SF story to me!

Going back to astrology again, how do you see this working if not through a predetermined universe? If free will exists would this mean that we write the stars rather than they write us?

In the press some months ago, a study showed that when people boarded an airliner without seat allocation, the aircraft was boarded and ready for take-off sooner than was the case when people had seats allocated. It`s like sheep herding themselves into an enclosure faster without the help of a sheep dog. But apparently it was the case.
Perhaps this could be an example of Chaos Practicality ?

Sounds like the tail wagging the dog but on a Universal scale.
No, I don`t believe astrology is a powerful force per se, but I think it can be a useful indicator and needs more positive research on a scientific level.
Astrology can be quite close in describing character traits of people. But as in all generalisations it falls apart when it boils down to specifics, rather like media psychology. And THAT works otherwise advertisers wouldn`t spend billions each year.

Here are three examples of what I'm thinking of--1. We take a step and cause the stars to reflect this (say in the constellations), 2. The stars force behavior upon us (say Orion makes us all bad tempered), or 3. the stars and humanity are co-dependent (which is something you could probably argue with modern physics).

Researching Astrology, while it has been subject to surveys and experiments, is difficult as it's a red rag to a bull. Our previous federal minister for education used an example of astrology to demonstrate bad research when he got the portfolio; a PhD in part determining Christ's star sign. I can't say if it was valid or not without the context, but naming this work in progress was a dreadful mistake!

Which, by utterly ignoring, brings me to my next point, the mind-body problem. This states that if there are two innately different substances which constitute reality (taken as matter and spirit), how do they interact?
Answers have ranged from saying there is only one (materialism or idealism) to the deterministic epiphenomenalist who believes we are ghosts who follow our bodies around.
