Yes it does: - Assume infinite time - so anything than can possibly happen will eventually happen - If it happens once it will eventually happen again...

What’s wrong with the simplist argument? The Actually Infinite exists. Reductio ad absurdum. No it doesn’t. Give me a counter example from nature of t...
September 19, 2018 at 10:37
You are making things complicated. Zeno’s paradoxes disappear if we assume time is discrete for example (IE then Archiles only has to cover a finite n...
September 19, 2018 at 10:28
Ok here is the proof that Actual Infinity does not exist: We have the concept of ‘Reductio ad absurdum’ which Wikipedia defines as: ‘In logic, reducti...
September 19, 2018 at 10:03
You are assuming time is continuous. - Assume we have a system - Watch it evolve over a finite time period - Will we observe it pass though an actuall...

My target is the use of actual infinity in the physical sciences.
September 18, 2018 at 19:11
We can’t conceive of logically inconsistent concepts like Actual Infinity in a logically consistent way. I’d allow for the existence of the inconceiva...

No wonder we cannot mentally conceive the Actually Infinite; it does not exist.
September 18, 2018 at 16:50

September 18, 2018 at 16:07
But it’s impossible to construct a smallest possible distance (1/infinity) - we can merely construct successfully smaller distances in a process that ...
September 18, 2018 at 16:04
If it is, it’s a potential infinity rather than an actual Infinity (you do understand the distinction?). The division of space takes time, first we mu...
September 18, 2018 at 15:46
So you are a Pythagorean? All is number? But you believe in actual infinity too? So that means you believe the physical world is actually infinite? Gi...
September 18, 2018 at 15:35
No, numbers are a figment of our minds so can be actually infinite. Time however is part of the physical universe so it can’t be actually infinite.
September 18, 2018 at 15:20
I believe that leads to contradictions. For example, how could we ever reach today if the past stretches to negative infinity (no matter many moments ...
September 18, 2018 at 14:52
The above refers to future which is potentially infinite which is not the subject of this thread. Past infinite time is however an Actual Infinity so ...
September 18, 2018 at 14:22
Yes I was discussing this briefly with a mathematician. The foundations of calculus do you indeed make use of actual infinity as defined in set theory...
September 18, 2018 at 14:13
Yes the paradox is due to the use of actual infinity in a logical argument. Imagine a timeless being existing permanently; he would be finite but perm...
September 18, 2018 at 13:32
I agree. The best language clarification I know is Aristotle‘s: https://en.m.wikipedia.org/wiki/Actual_infinity Relating this to maths, a potential in...
September 18, 2018 at 11:58
Yes; so an object with no start is a non-existent object; IE infinite time is impossible. Same argument for infinite space. The only thing I can think...
September 18, 2018 at 09:49
I like that story. Here is something similar for time: - Imagine an eternal being in eternal time - You notice he’s counting. You ask how long and he ...
September 18, 2018 at 08:16
That’s not correct, they make recourse to the limit concept which is not the same as actual infinity. I believe and so I thought did everyone that rel...
September 18, 2018 at 08:14
It’s a problem I agree but I can think of a way past 2 above: imagine as you get closer to the edge of the universe time slows down and right at the e...
September 18, 2018 at 07:43
The universal speed limit - the speed of light - is defined in terms of time (speed=distance/time) and is absolutely fundamental to the universe. Don’...
September 18, 2018 at 07:09
The unspecified ability to act is not synonymous in any way with omnipotence or infinite extent. We have the unspecified ability to act and we are not...

“Do you agree that every line (regress) of concurrent causality must terminate in a self-explaining cause?” - the prime mover? Yes I mainly buy it. “I...

I can sort of believe in an omnipotent god thanks to the wonder of the simulation hypothesis (https://en.wikipedia.org/wiki/Simulation_hypothesis), bu...
September 18, 2018 at 00:39
Good read thanks...
September 18, 2018 at 00:04
So you believe God is infinite? The problem with that is you are either infinite or you exist - not both at the same time. A finite god is much more n...

“But if one removed all phyiscal mass and energy, both the visible and dark, wouldn't empty space simply be infinite vacuum?” Dark energy maybe inhere...
September 17, 2018 at 23:41
Three instances where infinity clouds the issue: - The big rip - Black holes and the singularity - The debate over continuous/discrete I’m not suggest...
September 17, 2018 at 22:47
I don’t have your knowledge of quantum mechanics admittedly but I’m sticking with my claim - infinite space and time is nonsense: - Empty space has va...
September 17, 2018 at 21:21
Good for modelling and approximations I agree. It’s the use of actual infinity to stand real world quantities that disturbs me. Statements like space ...
September 17, 2018 at 19:48
Yes, to clarify I mean actual infinity in the context of the physical sciences. I.e. when it is applied to real world entities.
September 17, 2018 at 18:42
What created time? It must of been created either by random or on purpose: - A random process (eg quantum fluctuations) somehow create time. Seems an ...
September 16, 2018 at 13:19
The idea is that base reality is permanent but not infinite. The idea is nothing is infinite in a physical system and base reality is a physical syste...
September 16, 2018 at 05:19
In the domain of physics my view is actual infinities must be avoided. The actually infinite is impossible to achieve even with time - no matter how l...
September 16, 2018 at 01:30
I’m accepting time is infinite (for the sake of this argument) Infinite space does not matter because then the Boltzmann brains are almost infinitely ...
June 24, 2018 at 19:57
Yes but then there has been an infinite amount of time for the probability space to shrink: - Things that are impossible can’t become possible - Thing...
June 24, 2018 at 19:12
Oh dear I have the math wrong. Sorry to waste your time...
June 22, 2018 at 19:30
An assumption is required to complete the calculation. We have taken into account everything we know about dogs and we still have 30% of dogs for whic...
June 22, 2018 at 19:04
The survey found 70% of dogs nice and 30% of an unknown temperament. What do we assume for the 30% unknown? We have no evidence either way so the best...
June 22, 2018 at 18:49
You have not read (or have misunderstood) the relevant parts of this thread.
June 22, 2018 at 18:37
- It depends how you do the math, I am starting with a question like ‘is the dog nice?’ which has no evidence built into it, so I start 50% / 50% - th...
June 22, 2018 at 18:34
‘the desk is brown?’ - I know brown is one of (say) 50 colours so evidence of the distribution of the answer is in the question IE everyone would pick...
June 22, 2018 at 17:14
I see your point but you are picking questions with evidence built into the question: - so you ask the question ‘is the desk brown?’ - so we already k...
June 22, 2018 at 16:47
But we have omitted no evidence at all yet so we don’t know what the distribution is but we can still pick the statistically most likely distribution ...
June 22, 2018 at 15:45
- Ok accepted we have limited evidence on answers to yes/no questions; but we can still pick ‘the best answer’ in a statistical sense: - Do we go for ...
June 22, 2018 at 15:35
- You can. A little bit of common sense and statistics tells us, on average, the answer to yes/no questions (for which nothing else is known) is 50% y...
June 22, 2018 at 15:16
What I did was a meta-analysis including fact/science and reason/logic (I included the prime mover as a theoretical argument) for a science question. ...
June 22, 2018 at 14:40
God has not yet had time to clear up the confusion: There are about 10^24 star systems in the universe but there have only been 4x10^20 milliseconds s...
