I quoted that from the Laws of Physics, which regards anything material (physical) as an object.
Thus, you cannot exist in the same place at the same time as a moving train.
Not even by being in a parallel dimension, because then you're not in the same place... or perhaps even the same time.
Even in the scientific case of humans being able to pass through solid matter (
see illusionist Criss Angel), the basic principle remains -- as the molecules of the human body part and squeeze together in order for them to go around the molecules of the solid object... and a bit of the other way around... and therefore are not in the same place at the same time.
Now, if one is to look at it from a purely philosophical standpoint, one could argue a number of things:
-What is existence?
-Do I/the object really exist?
-What is time?
-What is place?
In any event, there is no real answer for a philosophical exploration of those points... else philosophy wouldn't have so many branches (metaphysics, deconstructionism, realism, et cetera).
But, they're fun to debate, so please continue.
