And what is an "object" for you? A mathematic entity or something more? Does it have lenght, width, height?
This is a good question for him since the answer is not trivial. In geometry a "geometric object" is not something you'd imagine it to be. I've seen people in another forum, who thought they knew what they were talking about, rant about their disbelief regarding the definition because it didn't fit in with their pre-established idea about what a geometric object is. I sure got insulted that day, merely because someone was ignorant of a definition (it appeared in MTW the same way I explained it but they basically told me that MTW wasn't to be believed! LOL!!!!)

Can you talk a bit about it? What did they write?

If space is not real, in what ever sense one chooses to define real, how is it possible to bend that which does not exist?

Absolutely, my friend. I'm not at home now so I'll have to do this off the cuff. I'll finish when I get hime.

In geometry a geometrical object is something with a set of components and defined according to how those components transform when transforming from one coordinate system to another. The people at the other forum thought that sounded more like a linear transformation than a geometric object. They seemed to have a predetermined idea of what such a thing would be and when it didn't meet their image they started to be jerks about it and started in with the derogatory remarks.

I talked about it here - http://www.thescienceforum.com/physics/36665-definitions.html
