Although theoretical physics postulates that other dimensions may exist (i.e. ‘String Theory’ and ‘Quantum Theory’, etc), these realities are mathematical probabilities, and not the product of sensory observation in the usual or mundane sense.
In the meantime, individuals can choose to progress human evolution by deciding to think beyond the current socially accepted limitations of perception. This may not be easy – as sometimes the powers that be will attempt to oppress any progress in a certain direction that might deprive a privileged minority of their power and influence. In reality, progression requires bravery, insight and resolve.
