Actual Infinity in Reality?

[RoadRunner79]

I appreciate all the effort you are putting in, but it seems like you are trying to over complicate things, and answer a number of other question that where not being posed.   It doesn't matter what time the train will arrive in Boston, and the dispute is not that you can reach the end.  

We have a line with a start and an end point.  We will assume that there are an infinite number of points between these two positions.
We progress through this line towards the end point, passing through each point in succession along the way.
From any given point, along that line we will always have more points between the current position and the end position.
All prior points must be reached, in order to reach the end position
If there is always another point, that is not the end, and which precedes the end, then end cannot be reached.
Therefore the end position is not reachable if there is an infinite number of points which must be traveled.  

The disagreement is not that you cannot reach the end position (I believe that motion is fairly well evidenced).  There is not a problem with the logic here.   The problem is that if you have to complete something that never ends, then you will never complete.  To say that it is infinite and that it ends, is contradictory.  Something cannot be both A and !A at the same time.

Ok, perhaps if you let go of your unscientific time "theory", you might see the answer clearly. I think the A-theory of time is your main hurdle right there, whether or not polymath's answer works just as well with the A-theory of time.

Was time a factor in what I said at all?

Now if you are arguing against motion from a different perspective or something, then make your case. Otherwise I don't' see how this fits it.
