humans have not invented a machine for traveling through time and space. The scientific and technological challenges associated with time travel are substantial, and we have not yet achieved the capability to manipulate spacetime in a manner that would allow for practical time travel.
The current understanding of physics suggests that time travel, especially into the past, would require the ability to manipulate extremely powerful gravitational fields or create and stabilize traversable wormholes. These concepts are still in the realm of theoretical physics and have not been realized in practice.
While scientific progress continues, it is challenging to provide a definitive timeline for when or if time travel technology might become a reality. The achievement of such technology would require breakthroughs in fundamental physics, advancements in our understanding of spacetime, and the development of highly advanced technologies that are currently beyond our reach.
It's important to approach the topic of time travel with skepticism and recognize that, at present, it remains largely speculative and confined to the realms of science fiction, theoretical physics, and philosophical exploration.
