Pyramids, Moon landing, flat Earth: Nick Kyrgios talks conspiracy theories on Logan Paul's podcast

FLASHBACK: Nick Kyrgios and his physio Will Maher meet with press to discuss the knee injury that forced the No. 19 seed to pull out of the Australian Open ahead of his first-round match.

While Aussie Nick Kyrgios remains on the sidelines rehabbing his knee, the 2022 Wimbledon finalist dropped by Logan Paul’s podcast “ImPaulsive” for a tell-all interview—and the wide-ranging conversation between the two stars didn’t disappoint.

Joined by two co-hosts, Kyrgios and American YouTuber Paul unpacked the highs and lows of the 27-year-old’s career, from bursting onto the scene at 19 with a victory over Rafael Nadal, to his unique self-directed approach to the game and how he's overcoming his mental health struggles.

The Break Point star was also quizzed on his “bad boy” image in the sport—a portrayal that appeared to puzzle Kyrgios, who responded, “I don’t know, they just branded me this ever since I came on the tour. Honestly, I don’t do anything crazy at all.”

But the conversation took a twist towards the end of the episode, as the discussion turned to their personal favorite conspiracy theories.

"I believe in that sort of stuff,” Kyrgios said with a grin. “I’m a massive conspiracy guy.”

The four ran through a series of popular theories, including whether the Earth is actually a globe, did the U.S. fake the Moon landings and who built the ancient pyramids in Egypt.

“I don’t even know what to believe anymore!” Kyrgios laughed, when asked if he believed the Earth was flat.

But the one theory the 27-year-old did feel strongly about? According to Kyrgios, the Egyptian pyramids—whose construction baffles historians and architects alike to this day—are actually not man-made structures.

“The doors are pretty big, and we as humans don't need doors as big as those ones," Kyrgios reasoned.

The group also discusses whether the Moon landings in the 1960s and 1970s were real or staged, a topic that spurred a heated debate after Kyrgios said: "America weren’t apparently even close to having anything successfully going up there, right?"

Kyrgios, who bowed out of the 2023 Australian Open due to the knee injury, is targeting Indian Wells as his first tournament back in action, according to his manager Daniel Horsfall.
