Can We Travel To The Past?

Is it possible to travel to the past? or does past exist in the universe to be precise? Nature seems to prohibit travel to the past for some reason. But is there a way to counteract this? How does time unfold in the universe?
Background:
Traveling to the past is a popular concept in science fiction, but according to our current understanding of physics, it's not feasible in the way it's often portrayed in movies or books. The idea of traveling backward in time raises numerous paradoxes and conflicts with our understanding of causality.
In theoretical physics, there are some speculative ideas that involve time travel, such as wormholes, closed timelike curves, and certain interpretations of quantum mechanics. However, these concepts come with significant challenges and unresolved questions.
For example, even if a theoretical construct like a wormhole could be created, it's uncertain whether it could be stable enough for anything to pass through it, let alone whether it could allow travel to the past without causing paradoxes.
Moreover, many physicists argue that the laws of physics, particularly causality, would prevent backward time travel. The possibility of paradoxes, such as the famous "grandfather paradox" (where you go back in time and prevent your own existence), suggests that the universe might have mechanisms to prevent such violations.
So, while time travel to the past remains a captivating idea and a staple of science fiction, it's currently regarded as highly improbable based on our current scientific understanding.

An interesting book is the novel We Appy Few. set in the middle ages, there is a scene where man stands on the shore and swings a bucket of water around. Inside the bucket is an hourglass. The man explains that that time is the sand in the hourglass, and can return just as the bucket returns its orbit. I believe the equation is B equals U over CK plus UT cubed. I like the idea of time travel looking like the word bucket.
