If we impose that under no force or gravitational field Lorentz transform must hold, my question is if the validity of Lorentz transform means that space time must be continous, or on the other hand if there may be a discrete model of space-time that preserves Lorentz transform.
For example if we can only measure a discrete time and space interval, could we find a lorentz transform (group transform) that leave the (discrete) element
[tex] (\Delta x )^{2}-c^{2}(\Delta t)^{2} [/tex]
invariant ? , for example if there could be a discrete space-time admitting some 'modified' Lorentz transform or approximate Lorentz transform.
