I was thinking about Zeno's paradox of motion today and decided on an explanation that I'd like to check. As I've heard the paradox stated, one premise is that in order to get from A to B you have to first get to the midway point, call it C. Then there are other premises resulting in the conclusion that motion is impossible. But doesn't the above premise already allow for the possibility of motion, making you agree that motion to C is possible before going on to claim that motion to B is not?
Perhaps there is another way to state the paradox, then?
A friend and I were discussing our philosophy class a while ago, and somehow we got onto the subject of the properties of things and the definition of a place. We began to argue about whether you can be in an object or in a place. I said that you can only be in an object and to be in a place is impossible. But you can be at a place. Example: you are in the building, but you are at the DMV. She said the opposite. That it is possible to be in a place. Who is correct?
Is the physical world proportional? What I mean is: is it possible, for instance, that we find a solar system exactly like ours except for the fact that every object (planets, stones, animals, trees, etc.) is one thousand times longer or less long? What if only twice longer?
And what about a different universe where even atoms (and elementary particles, if they have any length at all) were one thousand times "longer"? Is this meaningless?
Is it sensible to think that time is more fundamental than space, because one can just close one's eyes and relive memories, going back in time or prospectively go forward in time to predict something, without actually changing your position in space?
Science states that space is endless, and ever expanding. But, if we are inside the planet earth, the planet earth is inside the galaxy, the galaxy is inside space, then what is space inside? What is it expanding in? And if space is endless, how can it expand?
I submitted the following question a few days ago, but it has not been posted as far as I can tell. Perhaps the submission did not go through, but it is also possible that it was not posted because someone thought that the question had already been asked. Just in case, I post it again. Please notice that my question is quite different from questions like "Is the universe infinite?" or "Does the universe have an end?".
So here it goes: Are there two points in the universe such that, if you take the straight line through these two points and lay out yard sticks along that line to measure the distance between those two points, no finite number of yard sticks is sufficient to do so. In other words, are there infinite distances in the universe?
Again, please notice that this is NOT the same question as "Is the universe infinite?" The universe could be infinite without there being an infinite distance between any two points. Many thanks for responding.
