If there is something here at Stupid Stuff I Do we value the most, it is honesty. So you will have to completely trust us when we say Bruno’s descendants are still writing letters in the year 3056. You need proof? That is fair. All the proof you need is this letter which was sent from the year 3056 which has travelled through space-mail back to the present (past?) to ask much needed questions of the head of the UK Space Agency, Dr David Parker, regarding time travel.
