Answer 2

No, because time travel is currently impossible. This is because it can create a paradoxical universe. For example, if I go back in time and kill my grandfather or my ancestors, I should not have been born. Yet I exist. This phenomenon is called a tangential universe and is the reason time travel to the past isn't possible.
