All past is unreal, all future is unreal; everything that is imagined, or that is far away, or that is in the mind, is unreal. Only the present, physical and effective moment is real, that is to say, causality.
Shamansky, R. 2002. Presenteeism...Or When Being There is Not Being There.
How I would like to go back in time and be able to see places and witness situations in the history of the world. Moreover, I would like to go back to various moments of my childhood and perhaps relive them.
However, there is no current means to travel back in time or to become a child once again, or at least to see the past with a device, such as the hypothetical chronovisor, which I talked about in another article.
I know I am not a specialist, but giving my opinion is not a crime nor am I trying to denigrate the opinions of others.
Time travel has been the most desired illusion of mankind. It would give us the opportunity to unveil mysteries that break our heads in these times. Mysteries to which we can only make assumptions based on withered evidence.
According to Einstein time travel is possible.
According to the conventional description of the theory of relativity, material particles moving through space-time move forward in time (into the future) and to one side or the other of space. The fact that the total energy and mass are positive is related to the fact that the particles move into the future (in quantum mechanics a change of sign in time or a negative mass are equated).

Still, I believe that time is a mental object used to be able to measure reality and predict events, measure physical change or deduce events; Nothing in reality is static. This position I advocate is known as presentism.
I consider myself a bit of a Buddhist, not an orthodox practitioner, but I agree with its basic and original precepts.
The quote that starts the article is given by a Buddhist and within the doctrine of Buddhism, everything mental is not real, they are only images of the physical universe. They are useful, no doubt, but if we are dominated by them or believe them to be real, we are being blinded and are still not seeing reality as it is (it has nothing to do with conspiratorial ideas).
Now, time becomes relative because without a reference point (such as a clock), determining the amount of change that has occurred is speculative.
A clock is, in any case, equivalent to a tape measure. If this is so, then a second is a measure of physical change and a metre is a measure of space that changes or is affected by motion. No doubt both are mental objects for measuring reality.
Like Shamansky, I believe that the past and future do not exist except in our minds. They are only memories and predictions. Desires and longings. Time has no physical representation because it does not exist. The only thing that exists is space, and it is the only thing that changes.
In studying the world, we should not expect it to be as we would like it to be. It is better to let ourselves be surprised by it and then give it as objective an explanation as possible. And if no explanation can be given yet, create possibilities and consider them false until proven otherwise.
