Even if you still can't wrap your head around the standard definitions of infinity, doesn't the fact that there still has to be an infinite amount more events that have to happen before "any point in time" give you pause? By the very definition of infinity, you cannot traverse it to get to the events of today. There will always and forever be more events that must happen first!
You can't simply treat infinity as one thing that you can throw into a sentence because mathematicians use it in set theory. You are talking about an infinite series of events. These events have substance and are real things. You make a claim when you say there are an infinite series of events and you have to tell us how, against all logic, that is even possible.
Doesn't it seem odd to you that you can't find an article to explain this for you?
Unless you have something new, this is the last time I am going to say the same thing. 20 times is my limit.
How do I know if Penrose even believes his theory to be the best one? Even if he got the math right, that does not imply in the least that an actual infinity exists.
Do you think that every scientific paper that gets published is true or that even the authors think it is true?
Are you asking if space is an actual infinite of distance or substance, then no. If you are asking is space a potential infinite of distance or substance -- that seems possible.
It seem to me that different potential infinities can accumulate more quickly so there should be some mathematical differentiation for that, but at the end of the day, there is no upper limit so it does not make sense when talking about real objects--and that is the topic of this thread and what I intend to discuss.
Why are you counting *backwards*? Time moves forward! Nobody is counting backwards from today to the infinite past.
I'm not sure what you mean by there having to be an infinite number of *more* events before any particular moment of time. Where is the 'more'?
So, what we do *NOT* have is a situation
start----infinite time----now.
Instead, we have the situation for any point in the past,
infinite time----point in the past---finite time---now.
Bold mine.
I think what Steve means is, if we have time moving in a forward direction, how do we get to that one point in time from an infinite past? How do you get to that single event in time without beginning somewhere? If events are happening in succession, and time is infinite into the past, how would we ever arrive at a singular point in time? Wouldn’t you have to start somewhere to get there? I’m confused! Lol
