  I definitely think so, this is called the butterfly effect- there’s a great episode of the Simpsons about this, where Homer goes back to the Jurassic period and squashes a bug, which completely changes the future.

  Great episode of the Simpsons for sure. Back to the Future is also a very good film to watch on that matter. Unfortunately no way to test this, as travelling back in time is very unlikely to ever be possible.
