Does space have atomic structure and if it doesn't how can it be three dimensional?

No, it doesn't have atomic structure. If it did, it wouldn't be space. It would be matter, Basically, space is what happens between the bits of stuff called matter. To quote Einstein, "I wished to show that space-time is not necessarily something to which one can ascribe a separate existence, independently of the actual objects of physical reality. Physical objects are not in space, but these objects are spatially extended. In this way the concept of "empty space" loses its meaning." In other words, space isn't really there except as a description of what separates stuff. It isn't stuff. And outside the universe (which is made up of stuff separated by space) there is nothing. That's not nothing as in empty space. There isn't even space there. According to some, there isn't even an edge to the universe, because an edge would imply something to have a border with. So far as they know. There might be a neighbouring universe or two million, but we'll probably never get to borrow a cup of sugar from them or have to ask them to turn the radio down. As to dimensions, space isn't really there except in that it is not nothing (as mentioned above), so it doesn't have dimensions. It's what is between the stuff and nothing more. The stuff has dimensions. This is the Einsteinian view of things, which still seems to be currently accepted. However, next week or month Fred Ackroyd of Cleckheaton may publish his Grand Unified Theory of Everything and upset the applecart.

Perhaps a more interesting tangent would be "Is it quantised?" (or lumpy). Strike up the string section... Jan 01 07, 6:31 AM
