Can we time travel? A theoretical physicist provides some answers

Numerous time travel plots can be found in literature, television, and film, and it frequently appears in pop culture.

However, the concept is surprisingly old; some claim that Sophocles' Greek tragedy Oedipus Rex, which was written over 2,500 years ago, is the earliest time travel tale.

Does time travel actually exist, though? This is a fair inquiry given how well-liked the idea is.

As a theoretical physicist, I discover that there are numerous potential solutions to this query, none of which are incompatible.

The most straightforward response is that time travel is not feasible because if it were, we'd be doing it by now.

It may be argued that it is against the principles of physics, such as relativity or the second law of thermodynamics.

Technical difficulties also exist; it might be feasible but would require a significant amount of energy.

Perhaps the reason time must move in a linear fashion and we have no influence over it makes time travel impossible. Alternatively, perhaps time is an illusion and time travel is meaningless.
