Message 1611987 - Posted: 11 Dec 2014, 0:24:49 UTC

Interesting read. New theory big bang.

Did the Big Bang create a 'mirror universe' where time moves BACKWARDS? New theory could explain our past - and our future

The radical theory was proposed by Dr Julian Barbour of College Farm in the UK, Dr Tim Koslowski of the University of New Brunswick in Canada and Dr Flavio Mercati of the Perimeter Institute for Theoretical Physics, also in Canada.

Their research attempts to answer questions that remain about the ‘arrow of time’ - which is the concept that time is ‘symmetric’ and everything moves forwards.

They say that at the time of the Big Bang not one but two universes formed – both moving equally in each direction through time, but opposite to each other.

What is the rationale and evidence for this statement (conjecture) ??

It is certainly an interesting theory. Perhaps that is where the missing antimatter is from the Big Bang. Perhaps it is traveling backwards in time while regular matter travels forward in time (from our perspective).

If you were to take some antimatter and reverse time, it would interact the same way ordinary matter does to us in our direction of time. Gravity does not depend on which direction time is flowing. Additionally, it would mean that in our three dimensions of space and one dimension of time the net charge of the universe is zero.

Thanks CC, and everyone.

New theories suggest the big bang was not the beginning, and that we may live in the past of a parallel universe

Just theories in progress for now.

That ties in with my pet theory, that our local big bang which we call the universe is actually happening in the real universe.



A Universe within a Multiverse... Cannot possibly be proven but a possibility imo and also the opinion of quite a few cosmologists.

Not so likely...Universe has only 2 states:
1. Higgs field - stable Universe (currently, but in 10 to 100 years maybe not)
2. ultra-dense Higgs field - reset button!

So no, there is no backwards time...and there is no way things can go to higher state of complexity, energy, state...

Agreed on the first part of your statement but I fear I have to disagree on the latter part.

I've heard on YouTube two talks by Federico Faggin, the builder of the first microprocessor, the MicroComputer System 4, then called 4004, then 8008, then 8080 then ....
He has now turned to the problem of consciousness, like Roger Penrose ("Shadows of the mind") and has founded a Foundation to support researches in this field, the Federico and Elvia Faggin Foundation.
I cannot resume his ideas in a short post, but he believes we are part of an energy field (see also Freeman J.Dyson, "Disturbing the Universe") which antedates the Big Bang and will survive us. We are part of an Universe which tries to understand itself and has created a biological evolution to this purpose, giving birth to living beings of increasing complexity (and this reminded me of Pierre Teilhard de Chardin, SJ, and his "noosphere", which he has described in his posthumous book, "The human phenomenon"). All this is fascinating.

well in order to reverse the time...you would have to reverse the laws of thermodinamics...

and that would build up so much of complex structures, from parts...and release the energy by doing it? nope, doesn't work in my mind...


time is not linear and not constant...but can't be reversed!
you can slow it down...or speed it up...but never can stop it! unless you "reset the Universe" itself...in that ultra-dense Higgs field...which doesn't have time, as it doesn't have mass, nor it has matter...

I agreed on the first part Klik:) I do believe tho humans and other living creatures (or every particle in general) can go to a higher state of complexity, energy or being.

A higher state of complexity or order can be reached; but what is required is an input of additional energy. This energy can come from a source that is outside of the system being considered.

With no outside force applied, over time, a system or object will decay due to entropy. Therefore the argument that our (uni)verse will expand and decay until the last particle pops out of existence, in a few trillion years.

That force would be our Sun for us. The only supplier of energy. On a bigger timescale also energy will die and everything will end in the big rip imo.

There probably are some scientists around who think that an explanation for the universe should be put into context with the possibility of the existence of the divine, meaning compared or related to religious belief and faith.

In order to be able to understand how things are as they are, we always try giving a simple explanation to a complex problem and assume it tells the whole story.

For now, scientists only are able to explain certain things by means of given equations as they happen to be defined.

The subject of physics and particularly mathematics are much about such equations.

With equations, this means how thing relate or interact with other.

Laws are being handled by the police and justice system. Mathematical equations are supposed to be dealing with the possibility of the laws of nature instead and how things are related to and interacting with each other.

The Big Bang is supposed to be a moment of creation. Everything we know is based on the fundamental principles which were created in the first instant moment of its happening.

Time is only constant from observing it from one location point.

The speed of light, c, is apparently not a constant either.

Gravity was discovered with the falling apple on a poor scientist with the name of Isaac Newton sitting under a tree.

What a magnificent discovery he was able to make.

Anyway, this scientist was definitely quite good at what he was doing. When he eventually was challenged about currently accepted knowledge about given facts, things went out of hand and even the best of mathematicians had a hard time keeping track of things as they progressed.

The only two things that is not missing at all is matter and energy, which really is corresponding to be equal to each other, but with the addition of c, or the speed of light.

If the famous equation was presented or given as E=M, rather than the correct E=Mc2, most people would think that I was not that good at doing certain things, at least when compared with (sir) Isaac Newton.

Doing the business of experimental chemistry or even mathematics too soon becomes a mess. Where are the papers located?

It all once again becomes how the subject or principle of gravity is being explained.

Newton's three laws of gravity (of which the third one is quite complex) are trying to explain most given things as they happen to be, but still are unable to explain how mass and energy are constantly interacting with each other.

The Big Bang is not only about creation, gravity, or time.

It is also about our wish of understanding both microcosmos and macrocosmos and the way these two worlds are supposed to be governed by laws.

In between these two end-points of space and time you are finding our own world and the way we choose to be doing our regular business.

At least we are well able to understand everything that is happening right here.

Well, you have to think BIGGER!

If you have a Universe with opposite time, than it functions that something broken in our Universe get fixed and assembled...to fix & assemble something in higher state of energy - you have to input some energy...and we know that energy flows only in one direction!

And if you talk about outside energy putting into the system...that means you got something outside our Universe...some soup, unknown thing (doesn't have to matter) in which Universe expands...


So NO, I don't think we have phased Universe (in the same spot, but different laws of physics)...but yes I do think that there is more than we can see to the barrier of the Universe...and in those soup, there might be some other Universes with Higgs bozon slightly higher or lower GeV - which also means that some of those might be more stable or might not be stable...

Think bigger, like a Multiverse, of course! There's another theory I do believe in. There are several Big Bangs and several Universes within a Multiverse but the question is, where does it stop? Is it infinite? Are there any borders? sigh, time to go to work... Nice post mp!
