Empirical reality has been the focus of most scientific studies. But, humans have always been curious about how awareness, consciousness, sub-consciousness, or how the mind works. How are thoughts formed? Am I the mind? Is the brain responsible for consciousness? Are thoughts consciousness? Are there sub-conscious thoughts? Is the observable universe the truth? Is there a truth beyond reality? What is difference between a living being and a non-living being? What is the soul?

If it is not about consciousness, the next curiosity has been about space, time and matter. Is space finite or infinite? If space is expanding, where is it expanding into? What is time? Are there extra dimensions to space? Is time the 4th dimension? How many dimensions are present? How does space and time relate to consciousness? If consciousness was not present, would there be space and time? Is this whole universe just a thought?...
