Model Dependent Realism.

We most often in our lives ask this question: What is reality? Do we play any role in it and why most of the time we do not agree with others in explaining reality?

 

Philosophically, we see the Universe the way it is because we exist. Our existence is reality and every other thing in this Universe is illusion. All of us have our own version of reality and there is no absolute reality which is true to everyone in this world. This notion had already been proved by Quantum Physics which is the base of almost all modern technologies. We not only observe history but we also take part in it, change its characteristics and perceive it as a different reality with the help of particles like photon. This is what quantum physics says which is at microscopic level. But some of us say that at macroscopic level the reality is different and objects do not behave like subatomic particles. Living beings are made of cells and there are millions of cells in our body. The behavior or characteristics of the being is the probabilistic behavior of all the cells which is impossible to determine and so we all think differently. Reality is a state of mind and hence we can say that reality exists in probabilities and so changes from model to model or from person to person. This is what is known as Model dependent realism according to famous scientist Stephen Hawkins. But apart from this, there is one more problem when we include dark energy and dark matter. Through recent discoveries, it had been found that approximately there is only five percent matter which is visible or observable to us and the rest is dark matter and dark energy which do not interact with the matter we see in this universe. This dark energy and matter make galaxies and is also accelerating the expansion of the universe and we can’t observe it because it do not interact with the matter we see or observe. So once again reality is hidden as we are having knowledge of only five percent of our universe.

We are like sleeping in the world of dreams and our lives are just illusions. Whether we would be able to know about the truth or not in the future but one thing is for sure that we have the power of conscience to understand things and it will always guide us towards right path. Till then our quest is on.
