Remember when 'Cosmos' host Carl Sagan debunked flat Earthers with a piece of cardboard?

via YouTube

Over the past few years, there has been a growing number of people who believe the Earth is flat. A recent YouGov survey of more than 8,000 Americans found that as many as one in six are "not entirely certain the world is round."

Maybe there wouldn't be so much scientific illiteracy in this world if we still had Carl Sagan around.

Sagan hosted the original version of TV's "Cosmos" in 1980. It would be revived in 2014 with astrophysicist Neil deGrasse Tyson at the helm.

In the first episode of "Cosmos," Sagan easily proved the Earth was a sphere using a piece of cardboard, some sticks, and the work of an ancient Libyan-Greek scholar, Eratosthenes.

Carl Sagan explains how Eratostenes knows the earth is curvewww.youtube.com

"How could it be, that at the same moment, a stick in Syene would cast no shadow and a stick in Alexandria, 800 km to the north, would cast a very definite shadow? Sagan asked.

"The only answer was that the surface of the Earth is curved," he added. "Not only that but the greater the curvature, the bigger the difference in the length of the shadows."

Considering the distance between the two cities and the lengths of the shadows they produced, Eratosthenes was able to determine that the Earth had a seven-degree curve. He used that calculation to speculate the Earth was 25,000 miles in circumference.

These days we know that the earth is 24,860 in circumference, so Eratosthenes was 140 miles off, not bad for over 2,000 years ago.

Mom explains the common Boomer parenting style that still affects many adults today

Many are relieved to finally have a term for this experience.

“What they want is dishonest harmony rather than honest conflict.”

There are certainly many things the Boomer parents generally did right when raising their kids. Teaching them the importance of manners and respect. That actions do, in fact, have consequences. That a little manners go a long way…all of these things are truly good values to instill in kids.

But—and we are speaking in broad strokes here—being able to openly discuss difficult feelings was not one of the skills passed down by this generation. And many Gen X and millennial kids can sadly attest to this.

This is why the term “dishonest harmony” is giving many folks of this age group some relief. They finally have a term to describe the lack of emotional validation they needed throughout childhood for the sake of saving face.

In a video posted to TikTok, a woman named Angela Baker begins by saying, “Fellow Gen X and millennials, let's talk about our parents and their need for dishonest harmony.”

Barker, who thankfully did not experience this phenomenon growing up, but says her husband “certainly” did, shared that when she’s tried to discuss this topic, the typical response she’d get from Boomers would be to “Stop talking about it. We don't need to hear about it. Move on. Be quiet.”

And it’s this attitude that’s at the core of dishonest harmony.

“What that’s showing is their lack of ability to handle the distress that they feel when we talk openly about uncomfortable things,” she says. “What they want is dishonest harmony rather than honest conflict.”

“Keep quiet about these hard issues. Suppress your pain, suppress your trauma. Definitely don't talk openly about it so that you can learn to heal and break the cycle,” she continues. “What matters most is that we have the appearance of harmony, even if there's nothing harmonious under the surface.”

Barker concludes by theorizing that it was this need to promote a certain facade that created most of the toxic parenting choices of that time period.

“The desire of boomer parents to have this perception that everything was sweet and hunky dory, rather than prioritizing the needs of their kids, is what drove a lot of the toxic parenting we experienced.”

Barker’s video made others feel so seen, as clearly indicated by the comments.

“How did I not hear about dishonest harmony until now? This describes my family dynamic to a T. And if you disrespect that illusion, you are automatically labeled as the problem. It’s frustrating,” one person wrote.

“THANK YOU SO MUCH! I'm a 49 yo biker sitting in my bedroom crying right now. You just put a name to my darkness!” added another

Many shared how they were refusing to repeat the cycle.

One wrote, “This is EXACTLY my family dynamic. I’m the problem because I won’t remain quiet. Not anymore. Not again.”

“I love when my kids tell me what I did wrong. It gives me a chance to acknowledge and apologize. Everyone wants to be heard,” said another.

Of course, no parenting style is perfect. And all parents are working with the current ideals of the time, their own inner programming and their inherent need to course correct child raising problems of the previous generation. Gen Alpha parents will probably cringe at certain parenting styles currently considered in vogue. It’s all part of the process.

But hopefully one thing we have learned as a collective is that true change happens when we summon the courage to have difficult conversations.

The longest — and probably largest — proof of our current climate catastrophe ever caught on camera.

It was the largest such event ever filmed.

All GIFs and images via Exposure Labs.

Photographer James Balog and his crew were hanging out near a glacier when their camera captured something extraordinary.

They were in Greenland, gathering footage from the time-lapse they'd positioned all around the Arctic Circle for the last several years.

They were also there to shoot scenes for a documentary. And while they were hoping to capture some cool moments on camera, no one expected a huge chunk of a glacier to snap clean off and slide into the ocean right in front of their eyes.

It was the largest such event ever filmed.

For nearly an hour and 15 minutes, Balog and his crew stood by and watched as a piece of ice the size of lower Manhattan — but with ice-equivalent buildings that were two to three times taller than that — simply melted away.

As far as anyone knows, this was an unprecedented geological catastrophe and they caught the entire thing on tape. It won't be the last time something like this happens either.

But once upon a time, Balog was openly skeptical about that "global warming" thing.

Balog had a reputation since the early 1980s as a conservationist and environmental photographer. And for nearly 20 years, he'd scoffed at the climate change heralds shouting, "The sky is falling! The sky is falling!"

"I didn't think that humans were capable of changing the basic physics and chemistry of this entire, huge planet. It didn't seem probable, it didn't seem possible," he explained in the 2012 documentary film "Chasing Ice."

There was too much margin of error in the computer simulations, too many other pressing problems to address about our beautiful planet. As far as he was concerned, these melodramatic doomsayers were distracting from the real issues.

That was then.

Greenland, Antarctica, glacier calving

The glacier ice continues to erode away.

In fact, it wasn't until 2005 that Balog became a believer.

He was sent on a photo expedition of the Arctic by National Geographic, and that first northern trip was more than enough to see the damage for himself.

"It was about actual tangible physical evidence that was preserved in the ice cores of Greenland and Antarctica," he said in a 2012 interview with ThinkProgress. "That was really the smoking gun showing how far outside normal, natural variation the world has become. And that's when I started to really get the message that this was something consequential and serious and needed to be dealt with."

Some of that evidence may have been the fact that more Arctic landmass has melted away in the last 20 years than the previous 10,000 years.

A therapist is blowing minds by explaining how men can have sex with men and still be straight

"When straight men have sex with men, it's not a gay thing. It's a guy thing."

via Pexels and @drjoekort / TikTok

Gay sex and relationships therapist Dr. Joe Kort is causing a stir on TikTok where he explains why straight men who have sex with men can still be considered straight. If a man has sex with a man doesn't it ultimately make him gay or bisexual?

According to Kort, there can be a big chasm between our sexual and romantic orientations.

"Straight men can be attracted to the sex act, but not to the man. Straight men having sex with men doesn't cancel somebody's heterosexuality any more than a straight woman having sex with a woman cancels her [heterosexuality]," he says in the video.

Kort says he isn't erasing bisexuality, but that it's an entirely different phenomenon from straight men who have sex with men. Bisexual men are attracted to both men and women romantically, but straight men who have sex with other men, are only into the sex, not the person.

"When straight men have sex with men, it's not a gay thing. It's a guy thing," he explains in a later video.

For the man who has sex with other men and considers himself straight, it's more about getting off than getting close.

The video has had a lot of negative comments, most saying that men who have sex with men are gay or bisexual, case-closed. "Can I eat steak and still be vegan?" one commenter asks.

Many also accused Kort of being mildly homophobic for giving straight men the option to have gay sex without having to confront the notion they may be gay or bisexual.

Kort's videos point out the seldom-discussed idea that sexual and romantic attraction are not the same thing. Then, by adding the twist that someone can be into sex with a certain gender without feeling any romantic pull, makes things even more confusing.

@drjoekort There's a #difference between your #attraction and your #fantasies #lesbians #women #straightmen #lgbt
♬ Up Beat (Married Life) - Kenyi

The type of men that Kort describes could be aroused by another man sexually, but wouldn't feel comfortable or have any interest in being emotionally intimate with them. In fact, the emotional intimacy with another man may make them uncomfortable. It's just sex for sex's sake and what's wrong with that?

This same type of man may enjoy fantasizing about gay sex or watching gay pornography while having little interest in actually performing the act in real life.

Kort further explained his thoughts in a subsequent video.

"When I'm talking about straight men who sleep with men, I'm talking about a difference between who you're attracted to and what fantasies you have in your head. You have a sexual orientation and an erotic orientation," he says.

"And the things that are embedded in your erotic orientation that turn you on, that bring you to the finish line, can include other genders. You can imagine yourself being another gender," he continues.

Kort does a great job at explaining the difference between romantic and sexual attraction and that, for some, it spans gender. It may also help some men who are only into guys sexually and are unsure why they have zero romantic interest in someone, feel a little less confused.

Here's the first ever footage of a baby sperm whale nursing from its mother

How baby sperm whales nurse has been a scientific mystery for decades.

National Geographic/YouTube

We know that mammals feed their young with milk from their own bodies, and we know that whales are mammals. But the logistics of how some whales make breastfeeding happen has been a bit of a mystery for scientists. Such has been the case with sperm whales.

Sperm whales are uniquely shaped, with humongous, block-shaped heads that house the largest brains in the animal world. Like other cetaceans, sperm whale babies rely on their mother's milk for sustenance in their first year or two. And also like other cetaceans, a sperm whale mama's nipple is inverted—it doesn't stick out from her body like many mammals, but rather is hidden inside a mammary slit.

Most whale and dolphin babies nudge the mammary slit to expose the nipple, allowing them to "suckle." A sperm whale baby's head and mouth aren't really designed for suckling in the traditional sense, obviously, as its massive nose protrudes over its much smaller lower jaw. But even in the whale sense of mom shooting milk into a baby's mouth, it's been unclear how it works for sperm whales due to their oddly shaped heads. Photos and observations have led researchers to believe that the mother whale expresses milk into the water for the baby to ingests outside of her body, but the real mechanics haven't been clearly understood.

With the proliferation of underwater photography and filmography, it may seem strange that we don't have more nursing whale evidence to examine, but because baby whales can't breathe and nurse at the same time, nursing events are usually quite short. Even being in the right place at the right time to observe a whale nursing is rare, much less capturing it on film.

A four-part documentary series from National Geographic has provided, for the first time, film footage of a sperm whale baby nursing. It shows how the baby actually inserting its lower jaw into the mother's mammary slit, and the milk—which contains ten times more fat than human milk and is the consistency of yogurt—shooting directly into the baby whale's mouth.

The documentary series containing this footage, "Secrets of the Whales," was conceived of by National Geographic Explorer and photographer Brian Skerry and follows the stories of five different whale species—narwhals, humpbacks, belugas, sperm whales, and orcas. It was filmed in 24 locations around the world and took three years to make. Produced by award-winning filmmaker and conservationist James Cameron (of "Titanic" and "Avatar" fame) and narrated by award-winning actress and conservationist Sigourney Weaver, the series is sure to please whale lovers and nature lovers alike.

In addition to sperm whale babies breastfeeding, the docuseries shows how beluga whales name themselves so groups can keep track of each other, how baby belugas share their moms' call signs, how 30,000 humpbacks travel together from Australia to Antarctica and use breeches to talk to each other, and how a beluga pod adopted a narwhal into their bod—apparently the first ever cross-species adoption ever recorded.

Executive Producer James Cameron called the series a "challenging, daunting project" in a SXSW Conference panel last month."It's also so important for people to understand and for this film to illuminate how these creatures think, how they feel, what their emotion is like, what their society is like," he said, "because we won't protect what we don't love."

The series premiers on streaming service Disney+ on Earth Day, April 22.

The filmmakers hope that by sharing with people the unique identities of the whales they followed, they can inspire people to think about how these magnificent mammals can be better protected.

"It's inescapable that they're being poisoned by us, that they're being deafened by us, or their behaviors, all of their feeding strategies and mating strategies and reproductive strategies are being dismantled by all of this noise from shipping channels and military sonars and all that," Cameron said. "They're going to continue to decline. The right whales are down to about 300…We barely understand these animals, so I think we have to, as a society, we have to think about doing it better."

Indeed we do.
