Morgan Freeman doesn’t think any question is too controversial to ask.

He toes the line inWednesday night’s third-season premiere of his Science show, “Through the Wormhole with Morgan Freeman,” when he asks, “Is there a superior race?”

And Freeman says it was the Olympics that sparked his curiosity in the touchy subject.

“You see the Olympics, and who seems to excel where? Africans — long-distance running. Black Americans — sprints. Whites, Japanese, particularly white Americans and Europeans excel at swimming and winter sports,” Freeman told The Post. “So, why is that?”

The movie icon, who grew up in a predominantly African-American neighborhood in Mississippi, opens Wednesday’s episode by explaining, “I never thought of myself as better or worse than anyone. But all around town there were signs that other people did.”

Freeman brings the question to scientists and theologians. One scientist compares skin color to the variety of wing markings on Heliconius butterflies — which differ to protect them from local bird populations — concluding that race is only skin-deep. Another scientist compares average IQs across races, with the finding that (spoiler alert) Ashkenazi Jews have the highest average IQ.

But Freeman doesn’t think this particular finding reveals much.

“Personally, I don’t think IQs are worth anything to anybody,” he says. “You can’t give one group of people an IQ test and say it’s universal. If you took me to Africa, turned me loose in the Serengeti, I wouldn’t know anything; I couldn’t compete at all. It’s all about the context: Where you grew up and what you know.”

“Wormhole” has never shied away from controversial topics, with past episodes asking the questions, “Is there a Creator?” and “Can we live forever?” But while the topic of race is a sensitive one, Freeman isn’t so sure that the question of race superiority will spark controversy.

“Everybody who I’ve talked to recently has been intrigued by the question and the examination of it,” Freeman says. “I don’t know if we’re that concerned — really concerned as people — about superiority, race-wise. We’ve come to a sort of conclusion amongst ourselves, I think, that there is no such thing.”

It’s the asking — and not the answering — that interests Freeman.

“In high school, I had a class in physics which I found very exciting,” he says.

“Not that I knew anything or came away from that smart, but I was an A student for the simple reason that I always had these questions. I was put down by some other students because my hand always went up.

“But from those questions, I always got As.”
