"Possibly. But a better analogy is that the objects are people like us, 
sitting in various buildings that front on the street. Suppose that we want to 
send a message to someone over in Pudong. We write the message down on a piece 
of paper, and we go to the door and hand it to the first person who goes by and 
say, "Take this to Mr. Gu in Pudong.' And he skates down the street for a while 
and runs into someone on a bicycle who looks like he might be headed for 
Pudong, and says, "Take this to Mr. Gu.' A minute later, that person gets stuck 
in traffic and hands it off to a pedestrian who can negotiate the snarl a 
little better, and so on and so on,
until eventually it reaches Mr. Gu. When Mr. Gu wants to respond, he sends us a 
message in the same way."
