Our home, from space.

Sixty-four years ago, Soviet cosmonaut Yuri Gagarin became the first human to make it into space and the first to experience what scientists now call the "overview effect." This change occurs when people see the world from far above and notice that it’s a place where “borders are invisible, where racial, religious and economic strife are nowhere to be seen.”

The overview effect makes man’s squabbles with one another seem incredibly petty and presents the planet as it truly is, one interconnected organism.

In a compelling interview with Big Think, former NASA astronaut, author, and humanitarian Ron Garan explains how, if more of us developed this planetary perspective, we could fix much of what ails humanity and the planet.

Garan has spent 178 days in space and traveled more than 71 million miles in 2,842 orbits. From high above, he realized that the planet is a lot more fragile than he thought.

“When I looked out the window of the International Space Station, I saw the paparazzi-like flashes of lightning storms, I saw dancing curtains of auroras that seemed so close it was as if we could reach out and touch them. And I saw the unbelievable thinness of our planet's atmosphere. In that moment, I was hit with the sobering realization that that paper-thin layer keeps every living thing on our planet alive,” Garan said in the video.

“I saw an iridescent biosphere teeming with life,” he continues. “I didn't see the economy. But since our human-made systems treat everything, including the very life-support systems of our planet, as the wholly owned subsidiary of the global economy, it's obvious from the vantage point of space that we're living a lie.”

It was at that moment he realized that humanity needs to reevaluate its priorities.

“We need to move from thinking 'economy, society, planet' to 'planet, society, economy.' That's when we're going to continue our evolutionary process,” he added.

Garan says that we are paying a very “high price” as a civilization for our inability to develop a more planetary perspective and that it’s a big reason why we’re failing to solve many of our problems. Even though our economic activity may improve quality of life on one end, it’s also disastrous for the planet that sustains our lives.

It’s like cutting off our nose to spite our face.

Actor William Shatner, who spent years playing the iconic Captain James T. Kirk on the original Star Trek series, had a similar experience to Garan's when he went to space for real in October 2021:

"It was among the strongest feelings of grief I have ever encountered," Shatner wrote. "The contrast between the vicious coldness of space and the warm nurturing of Earth below filled me with overwhelming sadness. Every day, we are confronted with the knowledge of further destruction of Earth at our hands: the extinction of animal species, of flora and fauna … things that took five billion years to evolve, and suddenly we will never see them again because of the interference of mankind."

“We're not going to have peace on Earth until we recognize the basic fact of the interrelated structure of all reality,” Garan said.

However dire the situation looks from the surface of Earth, the astronaut has hope that we can collectively evolve in consciousness and wake up and embrace a larger reality. “And when we can evolve beyond a two-dimensional 'us versus them' mindset, and embrace the true multi-dimensional reality of the universe that we live in, that's when we're going to no longer be floating in darkness … and it's a future that we would all want to be a part of. That's our true calling.”

Astronaut unlocks a new phobia with a demonstration of being stuck in mid-air on the ISS

It's like that nightmare where you run as hard as you can and can't get anywhere.

Few of us ever get to float in space, much less feel what it's like to be stuck in mid-air.

Humans have all kinds of fears, from reasonable to totally irrational. But one fear most of us may have never even considered is being stuck hovering in mid-air, in the middle of a room, unable to make our body move in one direction or another no matter how hard or how fast we move our arms and legs.

Why would we, after all? Gravity works perfectly well here on Earth and we know how to make our bodies move in accordance with the forces of physics. The vast majority of us would never find ourselves in the scenario described above, thankfully. Many people have had that dream where you're running as hard as you can and not getting anywhere, but doing it while suspended in space is a whole other level of nightmare fuel.

In a video that has repeatedly gone viral, an astronaut demonstrated what it's like to be trapped in mid-air in a video from the International Space Station (ISS) and it unlocked a new phobia for people.

Can you really get stuck in mid-air on the ISS?

As retired Canadian astronaut Chris Hadfield explained in a 2011 Q & A after a 5-month stint on the ISS, it is possible to get stuck floating in the space station if you can't reach a wall to push yourself off from.

"Yes, it is—you can get stuck floating in the center of Node 1, where open space is biggest due to hatches on all sides," he wrote on Reddit. "But ISS has fans and forced air to mix and refresh the internal atmosphere, so there's always a small crosswind. Wait long enough, you'll get pulled to an air inlet."

So, you wouldn't be stuck like this forever but it might feel like it for a bit. One way to solve the problem if no one is around to help you would be to take off your clothes, wad them into a compact ball, and throw them, utilizing Newton's third law of motion to create a force that would propel you backward. Even the flailing around we see would move you incrementally in one direction if you repeat it long enough. You could also try blowing really hard, which would make for a very slow solution but would help you move a tiny bit. The only way to truly get stuck this way is for you to be nude with no air currents at all.

Of course, getting yourself into this mid-air hovering position in the first place is nearly impossible, since any momentum that pushed you into the middle of the room would move you out of it as well. You'd have to have your fellow astronauts purposefully put you in the center of Node 1 and hold you absolutely still before letting go in order to hover like that, which we see is exactly what happened in a longer version of this video. It's a fun experiment to watch, though, unless you're truly terrified of being stuck this way.

Zero gravity does weird things to the human body

Living on the ISS is strange, as our bodies aren't accustomed to a zero gravity environment. But the station has had people living there continuously since 2000 and we've learned a lot about what humans need to thrive without gravity. It's very important for astronauts on the ISS to exercise at least two hours daily, for instance, both for muscle and bone health.

As NASA shares:

"NASA has learned that without Earth’s gravity affecting the human body, weight-bearing bones lose on average 1% to 1.5% of mineral density per month during spaceflight. After returning to Earth, bone loss might not be completely corrected by rehabilitation; however, their risk for fracture is not higher. Without the proper diet and exercise routine, astronauts also lose muscle mass in microgravity faster than they would on Earth."

NASA adds that eyesight can be impacted by the zero gravity environment as well.

"The fluids in the body shift upward to the head in microgravity, which may put pressure on the eyes and cause vision problems. If preventive or countermeasures are not implemented, crews may experience an increased risk of developing kidney stones due to dehydration and increased excretion of calcium from their bones."

The fact that humans can now live in space is a remarkable testament to our ability to innovate, and the more we learn about what lies beyond the bounds of our planet, the more possibilities we'll find for the future of humanity (just as long as we always help one another out when we find ourselves stuck running in place).

Quantum immortality?

Might we never really pass on into nothingness? Has the world ended many times before? Are we in fact doomed to spend eternity unknowingly jumping from one dimension to the next? According to one TikTok theory, the answer is yes. And it's blowing millions of minds worldwide.

Joli Moli (@joli.artist) is quite used to spooking and perplexing viewers with conspiracy theories and alternative hot takes. In her video titled "Apocalypse...again," Joli introduced the concept of Hugh Everett's quantum immortality. Fans of the Marvel "multiverse," are quite familiar with this concept, where instead of experiencing death, "your consciousness just gets transferred to a parallel universe where you survived," the TikTokker explained.




Joli admits that this might burst the bubbles of those seeking the "sweet relief" of a widespread apocalypse. "If the quantum immortality theory is correct," she deduced, "you're just going to wake up in a parallel universe with no memory of the fact that you just survived an apocalyptic event."

According to Joli, the only sort of clue or hint you'd get that you might have woken up in a parallel world would be "new Mandela effects." You know, the strange phenomenon where all of a sudden there are two completely opposing memories of historical events? Yeah, quantum theory says that if you remember Curious George having a tail, you probably died in another universe.

Driving her point home, Joli added: "What I'm basically implying here is that in our reality, apocalypses happen every day … after the inevitable apocalypse occurs, you're going to wake up the next day in a new reality, and the next thing you know, you're going to find yourself on Reddit talking about 'since when did Pizza Hut have two Ts?!' Arguing with people who are native of this new reality, talking about 'it's always had two Ts'."

I for one would never want to live in a Pizza Hutt universe. Blech.

Still not sold on the theory? Joli has further arguments: "You don't believe me? Okay, it's been about 65 million years since the asteroids allegedly took out the dinosaurs. ... So you mean to tell me that in the last 65 million years, no other asteroids have come through the neighborhood, taken us out? You think we're just that lucky, huh? No other super volcanic events in 65 million years? We're just out there in space just dodging asteroids by luck, right? Earth doesn't have a steering wheel."

Hmmm. That's a good point.

Joli concluded with the upbeat sentiment that "Earth is probably always being taken out, and our consciousness just keeps getting transferred to another parallel universe, and another one, and another one. For all you know, the apocalypse maybe already happened last night…"

So far, in this reality anyway, the video has 4.9 million views. And—as to be expected—the video left many feeling uneasy.

One user commented, "Ok, I'm actually kind of freaking out right now coz I'm not the conspiracy typa guy, but you're like eerily making sense."

A few resorted to sarcasm as a defense mechanism (understandably), like this Twitterer: "Thanks I was overdue for another existential crisis."

The discourse got so intense, people were reporting physical side effects from the stress. One person wrote: "The thought of never being able to actually die is extremely depressing, and it's giving me a headache."

Another added, "Bruh, I'm just done with this anxiety. My body [is] emotionally [and] physically TIREDDD."

One commenter, who clearly had their priorities straight, wrote: "You're over here talking about extinction level events and I'm having to check on the two Ts in Pizza Hut."

It wasn't all gloom and doom though. According to indy100, some saw the potential of eternal life as a comfort against the loss of loved ones, while others finally got to make sense of their "world-ending" dreams.

If you have watched the original TikTok and are filled with burning questions, Joli posted a follow up Q&A video. A small disclaimer: You might be left with even more questions.

Though we may never really know what awaits us on the other side, it is interesting to think that we might live in a multiverse with infinite second chances. And whether or not this theory floats your metaphysical boat, it's fun to contemplate on one of life's biggest mysteries.

Pictured is Black hole TON 618, which contains more than 60 billion solar masses.

It’s almost impossible to really comprehend just how tiny the whole of humanity is against the enormously vast universe. But every so often, thanks to folks at NASA, we get jaw-dropping, awe-inspired video proof of it.

On May 3, NASA released an animated video to YouTube highlighting ten known supermassive black holes scattered throughout the cosmos, comparing their various sizes to familiar celestial bodies in our own solar system.

Noting the utter enormity of these fascinating objects, NASA wrote, “These monsters lurk in the centers of most big galaxies, including our own Milky Way, and contain between 100,000 and tens of billions of times more mass than our Sun.”


In just under 90 seconds, we take a journey through space with these galactic behemoths, starting with a black hole named J1601+3113, containing the mass of 100,000 suns, and ending with TON 618, which contains more than 60 billion solar masses.

Behold:

Awestruck? Terrified? A bit of both? You’re not alone. That was the general consensus in the comments section.

“Just swallowed my brain.”

“We are nothing in this universe but we still have so much ego to be proud of and fight for material things....”

“Mind-blowing.”

“Chills. Bravo!”

“Nobody knows anything anymore.....We're literally ants.”

“Mind blown overwhelmed and scary.”

Everyone might have a general concept of what a black hole is, but in many ways these phenomena remain a mystery. Catching real glimpses of their actual power is a rare, profound and often humbling experience. Same could probably be said of most space matters.

It can be so easy to get caught up in the constant dilemmas in our own world (out of necessity, much of the time). Sometimes all it takes is a larger view to infuse a little more awe back into our lives.
