      We are all time travelers really!
      Think about it, if you are 11 you have traveled 11 years though time, it may have taken you 11 years but you still traveled through time.
      We can’t travel faster than 1 year a year and we cannot travel backwards, but maybe one day there we will have such advanced technology and be able to time travel, just not today – or have I came back from the future to talk to you!

      Time travel is possible, according to one set of theories, and not possible according to another set of theories.

      Cosmologist and theatrical physicists have put forward multiple ways of how the universe came into existence, what its shed like and what will happen to it in the future.

      Two major theories are that the universe will collapse with a Big Crunch, like a reverse Big Bang, or that it will continue to expand forever.

      In a universe where the Big Crunch happens, time will be going ‘backwards’ when the universe is contracting. In the universe where it continues to expand, there is only one direction for time – forward.

      It might be possible to create wormholes – space-time tunnels – if the universe allows it. We just don’t have the definite answer yet about what our universe is shaped like to answer that. We will hopefully find out more about this in the future! 😀
