Time Travel Pros and Cons

Time travel is the concept of moving between different points in time in a manner analogous to moving between different points in space, generally using a theoretical invention, namely a time machine. It has a commonly recognized place in philosophy and fiction, but has a very limited application in real world physics, such as in quantum mechanics or wormholes.

Pro and Cons of Time Travel

Pros

• You can prevent events that happens, like calamities, death, wars, terrorist attacks etc
