At the moment we do not have the technology for time travel, but that doesn’t mean we won’t develop it in the future, there are several scientists currently working on this. According to the laws of physics I believe that it may be possible for us to travel into the future but we wouldn’t be able to come back again. I think it is not possible to travel backwards in time into the past though.
I don’t really know enough about Physics to give a technical answer. But I do think that if it was possible to travel back in time then we would probably have noticed a time traveler here. Unless they were very good and covering their tracks!
in theory yes- but like said we would probbaly already know about it. its a confusing prospect- and potentially very dangerous. perhaps we should learn from past mistakes rather than not experiencing them. you have to make mistakes in life to learn, thats what science experiemtns are all about. you would always be trying to better a situation that may or may not ever come……..
