... these multiple dimensions exist at the same time? As in parallel to one another? Could travelling between parallel universes and dimensions really just be a travel of time? Could we be subconsciously always travelling in time? From one dimension to the next. Is it just that the human race has/had/will never figure out a way to travel through these dimensions in different patterns? For example from the first dimension onwards (1-2-3-4 etc), but what if we could go in different directions (3-2-1-4 etc)?
Could every dimension of time be a separate parallel universe based on the decisions you make? Could there be a number of parallel universes equal to the number of possible decisions one could make? Could an object be in all three states at the same time in each parallel dimension?
Surely if travelling between these dimensions, or 'time' had/has/will ever exist, we would have already known about it? If it had existed surely it would have been something we would have all known about? For if someone was to travel from the future, they would pass on the message- and more and more 'time machines' could have been invented? Who's to say they could be time machines?
It could be that there is a mechanism for interaction between these universes that somehow permits all states to be accessible in some way and for all possible states to be affected in some manner?
