According to our current understanding of physics, the arrow of time and the increase of entropy are fundamental features of our universe and cannot be easily reversed.
The arrow of time refers to the asymmetry of physical processes with respect to time. In other words, there is a clear distinction between the past and the future. We observe that certain processes in nature, such as the shattering of a glass or the mixing of cream into coffee, are irreversible and exhibit a preferred direction of time. While the underlying laws of physics are time-reversible, the macroscopic behavior of systems tends to evolve in a particular direction, from a state of lower entropy (more ordered) to a state of higher entropy (more disordered).
Entropy is a measure of the disorder or randomness in a system. The second law of thermodynamics states that the entropy of an isolated system tends to increase over time. This means that, in general, systems move towards states of greater disorder and randomness. Reversing the increase in entropy would require the spontaneous emergence of highly ordered and low-entropy configurations, which is highly improbable.
While there have been some theoretical proposals and experiments that involve local or temporary violations of the arrow of time on a microscopic scale, these effects do not contradict the overall irreversible nature of macroscopic processes and the increase of entropy at the global level.
It is worth noting that our understanding of the fundamental nature of time and the arrow of time is an active area of research in physics, and there are ongoing efforts to explore these concepts further. However, as of now, reversing the arrow of time and the increase of entropy is not considered feasible within the known laws of physics.
