Time Travel: Reality or Fiction?
Imagine you own a watch that let's you time travel. One day, you get an idea to travel back to the 90's to meet your ancestors. You press a few buttons, and suddenly you're standing beside your young grandpa in his 20's under a ventilator in a hospital. Since you've never been the biggest fan of your grandpa, you decide to take off his breathing support (let's just assume haha!). Ventilator does its thing, and a few seconds later, no more Grandpa. But wait, if you killed your grandfather before he ever met your grandmother, you wouldn't have been born to be able to go back in time and kill him!....
