A video of an Elvis Presley concert has convinced conspiracy theorists that time travel is real.
The footage - which comes from the King's last gig in 1977 - shows the rock'n'roll legend crooning on stage in a bedazzled white suit.
It also shows the screaming crowds as they cheer and strive to get a better view of Elvis.
Among the concertgoers is one woman who conspiracy theorists have singled out as a potential time traveler.
The reason they have pinpointed her is that at one point in the footage, she appears to hold up a device that looks an awful lot like a modern smartphone.

One particularly suspicious mind shared the clip to Reddit with the caption: "Time traveler in Elvis Presley's last concert lady holding a mobile phone."
They weren't the only one who thought the device looked like a modern cell phone. "Definitely looks a lot like one of today's phone cameras. Not sure on what technology was around back then though that could compare," one person commented.

"I lived during that time and we didn’t have anything like that at that time. The item even has the camera area like a current iPhone," another chimed in.
A third added that it made sense the time traveler would be recording on their phone. "I mean, if I could go back and watch a live Elvis show...yeah I'd bring my phone too," they commented.



However, others weren't convinced.
One person pointed out: "If someone really had a phone and was taking a video, I think people behind her would be freaking out and would be like what the hell is that!?!"
"There were no cell phone towers back then so the phone would be useless except for taking pictures and videos," they added.
Others sought to explain what the device might actually be. "It's a silver video camera," one person commented. Another suggested: "Maybe it's a cigarette case? Just a guess."
