...Sounds like it may be quite interesting. 'A night with the Stars'. It all depends who the audience is, I suppose.

It's a replay from a couple of years ago. Very good viewing though.

Yup. A bit xmas lecture, but I enjoyed it.

Much better than a Christmas Lecture - Brian keeps the pace up and explains things nicely with some good chuckles along the way.

One thing I didn't know was that if you do something to a thing on Earth, every other electron in the universe changes. If I make something warmer, does the rest of the universe cool down to compensate?


Pity Mr Woss wasted a seat and can't do 34-7 but I suppose they needed a token fool to dumb it down a bit. Even James May looked a bit dopey.

OK, so I guess I'll be the first to ask a question in relation to this program.

Quantum Theory - I'm no expert as you will quickly find out.
Mr Cox stated that each electron in the universe is linked so that no two electron within the trillions of trillions of trillions of electron within the universe can be within the same energy level. ie. each electron is in a sense unique.

What I would like to know is that if 'information' flow is restricted to the speed of light, then how does one electron at one end of the universe instantly react to another electron at the other end of the universe if it approached to match the same energy state?

He was wrong, in a subtle way, but wrong.

Everything has a unique quantum state, a signature, and that is not quite what he said, he took an enormous short-cut to an answer.

I gave a far more accurate explainaytion here a few months ago.

I very much doubt Mr Cox could give an explanation in an hour long Xmas lecture type scenario. These things will always be 'dumbed down' so that folks can better understand it.

And to be fair, at that level, you have to.

In QFT the way things work is entirely different and Cox was embroiling himself in the macro-world rather than taking the viewer into the QFT realm, fields know no time nor do they have spatial co-ordinates, in the QFT Cosmos my bodies quantum states are adjacent to every other quantum state across the Cosmos.

But not all behave in this manner, some fields work in the manner he describes, they are specifically the Pauli field and the Dirac field, these fields behave as bridges to our macro-world, but others don't act as bridges and it is these further quantum fields that actually allow the individual signatures and the instant shuffle, but we can never test the instant shuffle, there is no way to prove it by his exposition, I can mathematically but it is barely comprehensible outside of a few thousand mathematicians around the world and not all of us agree about the detailed interactions across fields. But at least we all agree that it is the mechanism.

The annoying thing is that he had the opportunity to explain how apparent instant change occurs and he could have just extended the silly rope trick thing... and gone into seriously cutting edge QF Theory, Solitonic Time Wave theory and elemental signatures, real cutting edge stuff...

He should have got the two chaps down again and instead of a rope they should have been given a ribbon one side of which was red and the other white at each guy holds it flat with the red side up and each end held tight and that ribbon represents the full extent of the Cosmos, now at one end the strip is twisted 360 degrees so he still holds it red side up, but all along its length no single part is at the same angle of rotation as any other and you can use your finger to move the solitonic wave back and forth but at each end nothing changes, in laymans terms no information is passed from one to the other, but a lot happens along its length.

Now think of the two people representing the smallest unit of time and the ribbon is the cohesion between each tiny unit of time to the next, it still encompasses all the Cosmos as it all exists at the same moment.

So the ribbon is an instant in time and covers the entire Cosmos.

It can be twisted and manipulated into all sorts of configurations along its length and the twist travels to suit, you can bunch it up at one end or the other or add a twist so you for two solitons and if you let go of that twist they annihilate each other you can do loads of things and Field Theory allows that to happen.

So everything can change in an instant but no information exchanged FTL.

Now if he'd done that and followed the lines of my simple explanation he would have gained a huge amount of respect from me and the Scientific community as a whole.

It can also (with some modifiaction) explain better what 'spin' and 'isospin' actually is.

Really, Gene? You want Cox to go I to the utter intricacies of Quantum theory on an hour long program aimed at making quantum theory that little bit less odd? I suggest you get on YouTube, and make an hour long show telling us all about it so that normal people without degrees in physics can get a grasp of it.

What I've just written is very simple and (surprise to me) shatteringly accurate in the way Quantum geometry is perceived.

I'm more shocked than anything else how good the ribbon analogy is in conveying quantum signature, took me about a millisecond to realise the analogy too... clarity, it's intoxicating.

Having read through your replies, although concise and clear, I am still not following how an electron at one side of the universe can instantly react to another one at the other side with it being 'aware' of its energy state?

In the 'ribbon' example you say no information has been transmitted/received, but although each end is stationary there has been a wave sent and received. This is information no?
If it is also an instant reaction are we talking t=0 ?
Also bringing in to play the fact that the electron that is to change its energy level on earth for example has in someway pre-selected the electron on the other side of the universe that is also to change its energy level in order the t=0 can play out. (Therefore both being aware the change is about to occur?)


(Did I mention I am no exppert in quantum theory?)

The Cosmos is vast, our visible part is <15bn lyrs in any one direction, but the whole is >94bn lyrs across.

But everything exists at the same moment, it just take a while for the confirmation to arrive, just as when rays of light strike us a few minutes after leaving the Sun, the 'evidence' takes a while to arrive because it is information/energy

Time itself at the root of QFT is not relative it is comprehensive (that doesn't mean universal as we thought time was pre-Einstein) that is to say that it moves as a piece, the entire field operates in a single cohesive time and there is no time across it. It's 'now' everywhere in the entire Cosmos in quantum fields.

Relativity is a consequence of times macro-world presence as uni-directional dimension. (time always go forward)

Time is not a dimension to quantum fields just as photons have no 'time' signature as they do not experience time.

Quantum fields experience the past and the future as 'now'.

No, there was no wave, the ribbon remained red side up, all that happened was the ribbon could twist and turn to accommodate subtle motions, think of the subtle motions as the varying base states across the entire Cosmos, the ribbon represented the entire 3 dimensions of space.

See my previous post to understand that t='anything' in the QF state.
