The world is a complex place. And we humans  tend to believe that there is one field that will explain it all. It was theology, some 500 years ago, Then, theology was marked unscientific and a wrong explanation for the universe. Physics replaced theology, and now everyone thinks that physics is paramount. How do we know it wouldn't come tumbling down, as the assumptions on which it is built are destroyed, like theology? After all we are to a great extent building physics that explains the universe on the basis of observations that have been made on earth. For example, the laws of thermodynamics. And the assumption that all effects follow causes on the scale of time. You can theoretically prove things as much as you want, but till when? Ultimately they are based entirely on observations, which is what separates mathematics from the other science. As a matter of fact, physics is often challenged, by paradoxes, or concepts that comply with the laws of physics, but yet contradict themselves. Look at Zeno's paradox, or Banach-Tarski.
But everything gets simpler when we make one lear distinction. What is? and What is it that we are observing? Because never has there been something so vaguely related to each other in the history of mankind. If you keep distinguishing between what is and what seems to be, you will make a great thinker. Only when you make that distinction will you understand is all of your ideas and everything that you observe is just electrical signals from your senses, a system which is surprisingly easy to fool. A UC Berkley group of biotechnology students ran an experiment on some subjects where they gave everyone a virtual reality headset and noise cancelling headphones, and pitting them in several situations, and recorded their brain activity and other parts of the body. Subjects you were subjected to antarctic areas, actually felt cold! 2 of their senses were able to fool their skin's temperature sensors. A system so complex is very easy to delusion. But then how do you know when to believe and what to believe. How do we get to know the 'what is'? Hence the quest of finding one topic that explains everything. I am Daksh Gupta, and as always, never stop asking questions.
