      I have not made anyone from future yet (nor did anyone else, ever). If the time machine would be discovered in future, someone will travel back. Since that probably did not happen, I’ll say no 😉

      We don’t know really. Einstein’s theory doesn’t forbid time travel, so it might be!

      There’s two answers here.

      Yes, in theory you can travel backwards in time, but the only way we know how would be to mess about with big black holes. And it turns out you could never return to a time earlier than when you made the time machine. Sorry Dr. Who!

      Yes, we can travel forward in time, everyone does! You are moving forward in time at one second per second – think about it 😉

      Good question! Einstein’s theory of general relativity suggests that time travel might be possible, but it would involve travelling faster than light, which we don’t think is possible. There might be a way to do it, but it would probably be very hard and you could only send a few atoms back in time, and even that might be too difficult for us!

    Or could there be a law against that? Or why would they come back to exactly this time instead of going back to dinosaur times? Might it be more important to them to travel to the future than to the past?
