The exciting , recent discovery of gravitational waves from binary black holes did considerably more than prove once and for all the validity of the theory of Relativity by Albert Einstein. It has now opened discussion on time travel and renewed interest on travels beyond the speed of light.

This Charlie Chaplin video above purports to show a man entering from the right walking to the left holding a cell phone to his head. I think that's far fetched but still....
The 2nd video shows a woman walking in 1938 while talking on her cell phone.
There is also the video of the " Time traveling Hipster " along with a photo of Shirley Temple. All of this is in the 2nd link provided.
If true, who knows where this will lead us ?
