English abstract

Time travel involves moving to a time other than the present, past or future, in principle without a movement in space with reference to a local coordinate system. Time travel can be done by a material body that may or may not be a living being, and for which a special device called a time machine is usually used. Time travel is a recognized concept in philosophy and science, but whose possibility is highly contested, giving rise to numerous paradoxes in both philosophy and science. Time travel is considered by some to be supported by both general relativity and quantum mechanics, but there is unanimous consensus that it is not feasible with current technology. The issues raised are different for time travel in the past versus time travel in the future.

Romanian abstract

Călătoria în timp implică deplasarea într-un timp diferit de cel prezent, în trecut sau în viitor, în principiu fără o deplasare în spațiu cu referire la un sistem de coordonate local. Călătoria în timp poate fi făcută de un corp material care poate fi sau nu o ființă vie, și pentru care se folosește de obicei un dispozitiv special denumit mașina timpului. Călătoria în timp este un concept recunoscut în filosofie și știință, dar a cărui posibilitatea este foarte disputată, dând naștere la numeroase paradoxuri atât în filosofie cât și în știință. Călătoria în timp este considerată de unii acceptată atât de relativitatea generală cât și de mecanica cuantică, dar există un consens unanim că nu este fezabilă cu tehnologia actuală. Problemele ridicate sunt diferite pentru călătoria în timp în trecu față de călătoria în timp în viitor.
