Just before I go to bed...

what is time travel? where is time travel? let me do one better, why is time travel? ever wondered how Time Travelling works? have questions? lets figure it out together. Movies like HotTub TimeMachine, Avengers EG, Back to the future, Time Traveler's wife etc showed us that travelling through time can be elegant but shows like Dark, Fringe, DR who, Umbrella Academy showed us that it can be messy. so where is your pick when it comes to Time Travel and is there a proper way to do it?
