Honestly, time travel is an unknown. We can't say it's definitely possible. We can't say it's impossible. All we can do is guess and try to learn more. Maybe the LHC will tell us something about it? There have been some theories that it potentially could.

Those who have been involved in time travel technology have agreed that time "travel" into the past is impossible unless the technology exists in the particular time to which one wishes to travel. It's like making a phone call to someone who hasn't got a mobile phone, the technology must exist at both ends of the traveler's journey.
