Grandfather Paradox- Go back in time and kill one of your ancestors before a later ancestor is born/concieved. It would cause you to never be born, yet if you don't exist you couldn't kill them to begin with thus you will exist to kill them so you won't exist to kill them so you will exist to kill them....... Immovable Object meets an Unstopable Force- This gets into quantum physics. If the object cannot be moved, it will not allow the other object to push it. If the forced object cannot be stopped, it will continue moving after meeting the immovable object. I see two ways to overcome this seemingly paradoxical situation: the objects will pass through eachother without touching as nothing is truly solid; or the unstoppable force would push through reality itself to continue moving once it meets the immovable object, possibly forming a black or worm hole.
The Asherlee Paradox- Asherlee has a thread that is currently stickied. It was made to teach people how to make threads in a way in which they will not be locked. That thread is locked.
But a big paradox is when your future self visits you. In the future, you never know when you should go back in time so you chicken out and never go. Then your future self would have never visited you in the first place.
All these ime travel paradoxes are not paradoxes because time trave is not possible but even if it was then I personally feel that an alternative universe would have been created with your old one now blocked off to you. Or possibly you could go back to it knowing that in another universe it went OK.
