He has an interesting take on it.

Is this still a respectable if minority interpretation of quantum effects? Or is it discredited totally?
I do rather like the idea that somewhere in a parallel universe I'm driving my XJ13 along a derestricted motorway to my job as a TSR2 pilot.
If infinity was really infinity then eventually you'd encounter exactly that. And then a bit further along, the same but one of the trees is different.... and so on...

Expect that wouldn't quite be me just someone identical to me. What intrigues me is the thought that what might have happened if I'd done something different in 1967 is being played out somewhere.Infinity is odd anyway. Not only does everything, however unlikely, happen somewhere. It happens an infinite number of times. But still far less often than more likely things.

You could argue that if infinity is infinite then by definition every concievable variant is not only likely but certain!Dr Jekyll said:

Exactly, so what do we mean by likely?ATG said:

Think of any finite subset of the infinite thing. However large you make the subset, the relative frequency of occurrence of the events remains constant. You can make the subset arbitrarily large and that constant doesn't change.It's some infinite numbers being higher than others that I have a problem with.

Unfortunately that also means that somewhere you are driving your XJ13 along a derestricted motorway to your job as an estate agent. I do rather like the idea that somewhere in a parallel universe I'm driving my XJ13 along a derestricted motorway to my job as a TSR2 pilot.

Exactly, so what do we mean by likely?I might suggest that infinity removes probablility. In fact I might publish that and claim a Nobel Prize.
Simpo Two said:
Reading this back, I view 'likely' and 'certain' are mutually exclusive. 'Likely' has a probability attached (ie it may or may not happen), whilst 'certain' is, well, certain! (or P1.0 as I think we used to express it).

The distributions would be different though. If I roll two dice an infinite number of times and plot the sum against the number of rolls, there'll be many more 7's and 8's then 2's and 12's. The question is though, what happens when the dice has infinite sides? I might suggest that infinity removes probablility. In fact I might publish that and claim a Nobel Prize.
Does infinity have to abide by the rules of physics as we understand them? So, for example in one of these universes, is there someone (We'll call him Han Solo) flying a star ship that is more than capable of travelling faster than light?
If there are infinite possibilities, then the physical universe as we understand it must have rules that can be broken.
Now, for a forum predominantly made up of agnostics or atheists (as I am one too), in one of these universes there actually is a God, that created that universe (possibly only 6000 years ago).
There's a Universe where Rick grimes is spending his days killing Zombies, or where Jon Snow knows nothing!

Just reflect on the fact that there is at least one Universe where you are Diane Abbott....and in all possible Universes, there is a techiedave cyber-perving in pursuit of you.If there are infinite possibilities, then the physical universe as we understand it must have rules that can be broken.

Then just be very, very thankful that this isn't that Universe. Yet.
