If I'm not mistaken, it is thought that space is divided up into quantized little indivisible chunks, the size of which is called the Planck length.(adsbygoogle = window.adsbygoogle || []).push({});

Also, the space of the universe is thought to be expanding. We could have 2 objects stationary relative to one another at some time t_0, then allow space to expand from t_0 to t_max, and these 2 objects would then be at a greater separation.

Does this mean that each little block of space is itself stretching out (ie. the 2 objects have the same number of blocks between them at t_0 and at t_max)?

Or, is it that they stay the same size, but more blocks exist between the 2 objects at t_max than there were originally at t_0?
