In honor of the 50th anniversary of “Doctor Who,” here are some stories about some people who claimed to have unlocked the secret of time travel…or maybe not.

• Jacques Vallee is a French scientist who promotes a theory he calls Interdimensional Hypothesis. In short, Vallee says that UFOs—flying saucers and other alien spacecraft that humans have reported seeing—aren’t aliens from a distant planet…they’re time travelers. Vallee was even a UFO consultant on Steven Spielberg’s Close Encounters of the Third Kind, although he couldn’t convince Spielberg to make the movie about time-traveling creatures instead of aliens.
• If anybody were smart enough to figure out time travel, it would have to be Stephen Hawking. In 2012, the famed theoretical physicist Stephen Hawking tried to settle the “is time travel possible?” debate forever. The answer is “no.” Announcing that he had “experimental evidence that time travel is not possible,” he told reporters that he had held a party for time travelers—on June 28, 2009. Theorizing very simply that if time travelers from the future did, in fact exist, they would have known about Hawking’s time traveler party, and traveled back in time to attend and prove that time travel is possible. He even sent out the invitations after the party was supposed to be held, just to test their time travel capabilities. Still…nobody showed up.
• In 2013, a scientist named Ali Razequi claimed to have built a working time machine, well, really a fortune-telling machine. Razequi, who works for Iran’s Center for Strategic Inventions, says his devices uses a complex series of algorithims to predict the next five to eight years of anyone’s life. The story was first reported by Fars, Iran’s state-run news service, but not even the Iranian government thinks Razequi’s desktop-computer sized device is legitimate. Razequi, however, claims that the Iranian government is keeping his invention because they fear “the Chinese will steal the idea and produce it in millions overnight.”
