Today is November 14th, 2015. Let's say I wanted to go to an alternate timeline (so I won't be erased or anything) on May 14th, 2012. If I brought with me my iPhone 6, would I receive texts my past self would have received with his iPhone 4c Would I lose my photos on iCloud? Would the music on my Spotify and Music playlist disappear? Would my iOS 9 crash? Would the NSA figure it out? Should I get a fake ID?
I really need to know all this because I have constructed a time machine and plan to go back to the past tonight and need to pack. I moved approximately 2.5 years ago from the west coast to Midwest. I plan to go back in time and give myself a year to get to the west coast and formulate a plan to stop myself from moving. Then I plan to secretly guide my younger self through life while I start a new life in the past. Should I get a fake birthday and secret identity so I can still have doctor appointments in case of health issues? Anything else I should worry about? Is this illegal?
