If I had a time machine I would visit old eras like the season of the dinosaurs,the moment when universe was created,the neolithic era etc.I am not sure if I would like to visit the future, because I think that will be bad...
Yep, go back in time so to pet the dinosaurs. Hey, did you take into consideration that the air wouldn't be breathable for humans when you arrive due to its chemical makeup? As far as visiting the universe when it was first created, did you map out a site where to land your time machine? If not, simply ask the first person you see as to where to park.
