Appraisal of Chronological Development of Physics with Creation of Universe and Uncertainty of Future

Abstract

The chronological development of physics has gradually shifted humanity's worldview from a deterministic, expectable universe to one characterized by probabilistic outcomes and inherent uncertainty. This shift is principally driven by the transition from classical to modern physics, intensely influencing theories about the universe's creation and future. The integration of relativity with astrophysical observations like Edwin Hubble's discovery of an expanding universe and the detection of cosmic microwave background radiation led to the widely accepted Big Bang theory. Physics allows cosmologists to look back in time and understand the universe's earliest moments, starting from a hot, dense singularity approximately 13.8 billion years ago. The study of tiny quantum fluctuations in the early universe, observed in the cosmic microwave background, provides ‘fingerprints of creation’ that grew into the large-scale structures we see today. While classical physics offered a deterministic view, modern physics, particularly quantum mechanics and current cosmology, embraces uncertainty regarding the universe's ultimate fate. The future is largely unpredictable in detail due to factors like the precise nature and behavior of dark energy, which is accelerating the expansion of the universe. Current theories about the end of the universe like the ‘Big Freeze’ the ‘Big Crunch,’ or the ‘Big Rip’ and those depend on these unknown variables and the ongoing modification of fundamental physics. The future remains unknown and mostly unpredictable in specific detail. This journey reveals physics as a continuously evolving field that has moved from a desire for perfect prediction to an acceptance of probability and the dynamic, open-ended nature of cosmic inquiry. This paper will try to apprise and analyze the history and creation of universe and uncertainty of future on the basis of chronological development of theories of physics.
