Proof of Time Travel?

I once read a book about time travelers that were pulled out of their timestreams at the moment of their death and transported into the future. It was an interesting premise, even if it quickly became an uninteresting story. When I was young I wished I lived in Victorian times, wearing gorgeous dresses and horseback riding and flirting with handsome gentlemen. Knowing my luck I would end up as a seamstress or fisherman's wife so maybe I'm better off here! Still, the idea of time travel has always fascinated me. Maybe that's why I'm such a Dr. Who fan.

The most compelling evidence I've ever seen of time travel is a painting by Bonaventura Salimbeni in 1600 A.D called the "Glorification of the Eucharist". The artwork is currently on display at the St. Peter church in Italy and depicts a metallic looking sphere being held by the Holy Trinity. The object looks suspiciously similar to Sputnik although historians claim it's simply the artists imaginative representation of the celestial sphere of the universe.

Then there's the curious case of Mr. Sergei Ponomarenko, a man found wandering Kiev on April 23rd, 2006. He was wearing outdated clothing and carrying an old style camera that appeared brand new. When the role was developed there were images of Kiev in the 1950s and a bell-shaped object as well. The gentleman said that he had encountered the object and then immediately afterwards was brought to his current location. He was carrying a Soviet citizen ID card which said he'd been born in 1932. He disappeared a few days later.

So is time travel real or or fantasy? Is it aliens or humanity from some future time? Or maybe it's just Doctor Who carrying around passengers in his tardis!
