Time is really all about perception.

You're scrolling along, minding your own business on the internet, when this little chestnut comes across your timeline: "1980 and 2023 are as far apart as 1937 and 1980. Sleep tight, old fogies!"

Wait, what? Your first reaction is, "That can't be right," so you pull out the calculator and do the math yourself—several times because you're sure you must've missed a number somewhere each time. You remember how long ago 1937 seemed in 1980, and there's absolutely no way that much time passed between 1980 and 2023. Buy you're wrong. As the warped reality of time washes over you, you sit in stunned silence, contemplating the existential crisis you've just been thrown into.

Why does time work this way? Why does it seem to get faster and faster and condense to make decades seem shorter and shorter as we age? And perhaps more importantly, how the heck do we stop time from feeling like a runaway freight train?

Here are a few theories about what creates the freight train phenomenon and what to do about it.

Time perception is relative—and kids perceive it differently

"Time flies when you're having fun" is a saying for a reason. Time also drags when you're doing drudgery work and feels like it stands still in moments of significance. And yet the ticking of seconds as they go by doesn't change tempo. We measure it with steady, unchanging beats, but how it feels changes constantly.

This relativity exists in every passing moment, but it also exists in the bigger picture as well. The years felt like they passed by much more slowly when we were children, and by middle age, they feel like they pass in the blink of an eye. The pandemic gave us an even greater sense of this relativity as disruptions to our normal routines and the stress associated with the COVID-19 years messed with our sense of time. (On an odd side note, surveys show that our time perception during the pandemic varied a lot from place to place—people in some parts of the world felt that time moved more slowly, while others felt time moved more quickly.)

According to a 2023 Hungarian study published in Nature Scientific Reports, very young children perceive time differently than older children and adults. Researchers split 138 people into three age groups—pre-kindergarten, school-age and adults 18 and over—and showed them two videos of the same duration, one that was "eventful" and one that was "uneventful." Interestingly, the pre-K group perceived the eventful video to be longer, while the older children and adults saw the uneventful video as longer.

The way the study participants described the length of the videos in gestures was also telling. Young children were much more likely to use vertical hand gestures, connoting volume or magnitude, to indicate a length of time than the other two age groups. School-aged kids and adults tended to use horizontal gestures, indicating time as linear, increasing with age.

Our neural processing slows down as we age

Professor Adrian Bejan has a theory based on how neurons process signals. As we age, our neural networks increase in size and complexity and, as a result, process visual information at a slower rate. That slower processing means we create fewer mental images each second than we did when we were younger, thereby making time seem to slow down.

“People are often amazed at how much they remember from days that seemed to last forever in their youth, Bejan shared with Harvard University. "It’s not that their experiences were much deeper or more meaningful; it’s just that they were being processed in rapid fire.”

In other words, processing the same number of mental images we did in our youth takes longer now, somewhat counterintuitively making time seem to pass more quickly. So goes the theory, anyway.

It might simply be about time-to-life ratios

Another popular theory about why time feels different as a child than it does as an adult is the ratio of any given day, week or year to the amount of time we've been alive. To a 5-year-old, a year is 20% of their entire life. For a 50-year-old, a year only is 0.2% of their life, so it feels like it went by much more quickly.

It's also a matter of how much change has happened in that year. A year in the life of a 5-year-old is full of rapid growth and change and learning and development. A year in the life of a 50-year-old probably isn't a whole lot different than when they were 48 or 49. Even if there are major life changes, the middle-aged brain isn't evolving at nearly the same rate as a child. A 50-year-old looking back at the past year will have a lot fewer changes to process than a 5-year-old, therefore the year will seems like it went by a lot faster.

“Our perception of days, weeks, years and that kind of time seems to be especially influenced by our perspective: Are we in the moment experiencing it, or are we looking backward on time?” psychology professor Cindy Lustig told the University of Michigan.

The key to slowing it all down? Be mindful of the present moment.

Lustig has a point. When we are in the moment, our perception of time is much different than when we look back. So, being fully conscious in the present moment can help us rein in the freight train effect.

One way to do that is to be mindful of your physical existence in this moment. Feel your heart beating. Feel your breath going in and out. Cornell University psychology professor Adam Anderson, Ph.D., conducted a study that found our perception of time may be linked with the length of our heartbeats. (Study participants were fitted with electrocardiograms and asked to listen to a brief audio tone. They perceived the tone as longer after a longer heartbeat and shorter after a shorter one.) He suggests starting a stopwatch, closing your eyes and focusing on your breathing for what you think feels like a minute. Then, check your time to see how accurate your estimation was.

“This can give you a sense of how much your experience of your body is related to your experience of time,” Anderson told WebMD. “It will help teach you to enjoy the pure experience of time.”

You can also use focused breathing to purposely slow down your heart rate, and thus slow down your time perception. “We show that slow heart rates—that is, a longer duration between heartbeats—dilates time, slowing it down," Anderson said.

We can also alter our perception of time by taking in novel experiences, such as traveling to new places. According to Steve Taylor, author of Making Time: Why Time Seems To Pass at Different Speeds and How to Control It, people who go on adventurous trips report that their vacations feel longer than those who choose a predictable destination. You can also make small changes to your daily routine, such as trying new foods or taking a new route home from work to take in some new stimuli and slow your perception of time.

A study in 2024 found that people who do intense exercise experience a time warp, feeling like they exercised longer than they really did, so if you want to temporarily slow down time, you can push your body hard during a workout.

Finally, try to take in the world the way you did as a small child. Take note of life's wonders. Engage fully in whatever you're doing. Notice details and take mental pictures as much as you can. Time goes by fast when we're distracted, so training our attention on the here and now can help. Ultimately, we can strive to perceive time more like we did when we were little, in its full depth and magnitude instead of a narrow, straight line.

These 13 stunning photos won gold in the 2021 World Nature Photography Awards

See how talented photographers capture the beauty and wonder of our world.

Photographers capture some of nature's best moments.

The World Nature Photography Awards showcase the best of nature's moments caught on camera, and each year, the world's best photographers compete for gold in a range of categories. In the 2021 photo contest, Amos Nachoum from the United States won the top cash prize award of $1,000 for his image of a leopard seal about to capture a defenseless gentoo penguin. Four years later, the images are still unforgettable.

Getting the split-second photo was no easy task. Nachoum had to wait for hours on the remote island of Plano, off the Antarctic Peninsula, for the right moment at low tide when the seals entered a lagoon to catch their prey. Unfortunately, the photo is one of the last moments of the young penguin’s life. “The terrified penguin tried to escape as the game continued. But soon, the end came,” Nachoum said in a statement.

Nachoun's full photo statement: "For hours, I waited for the low tide to arrive along a shallow lagoon on a remote island off the Antarctic Peninsula. Like clockwork, the leopard seal arrived in the lagoon just before low tide. It put its head in the water and looked just like a rock sitting in the receding water. The young Gentoo penguins only dare to enter the water when it is shallow and when they got close enough to the seal, it turned its head at lightning speed, catching one of the penguins by its feet and taking it to deep water. Once the seal reached open water, I followed it and swam parallel to it, observing its actions. To my surprise, it let go of the penguin twice. Each time, the seal chased after the penguin again, as if it was enjoying the game. The terrified penguin tried to escape as the game continued. But soon, the end came."

Other winners included a remarkable shot of a humpback whale just outside New York City, a majestic photo of an orangutan in a river, and an arctic fox braving the frozen tundra in Iceland.

The photographs are a wonderful example of the dedication and care taken by nature photographers, but they’re also a reminder of our duty to care for the environment.

“The World Nature Photography Awards were founded in the belief that we can all make small efforts to shape the future of our planet in a positive way and that photography can influence people to see the world from a different perspective and change their own habits for the good of the planet. 2021’s competition saw entries come in from 20 countries across 6 continents,” the World Nature Photography Awards said in a press release.

Here are the other photographers who won gold in the 2021 contest.

"This shot came out of a 'nothing' outing to a local park. It was the middle of a sunny summer day with harsh light and little activity. After going out with low expectations, I came across this tiny Pacific Tree Frog on a flower. After waiting for it to move into a more photogenic position on the flower, and trying repeatedly to catch the mottled light through the tree’s leaves above it at exactly the right spot, I got exactly what I was hoping for. It proved to me that there’s really no bad time to head into nature with a camera!"

Science

Man found a newborn squirrel in his driveway, raised it, and now they're best friends.

Robert "Bobby" T. Squirrel's personality is "about halfway between a cat and a dog."

Bobby the squirrel lives outside now, but still comes in for a visit pretty much every day.

In late 2022 when Ron Milburn came across a tiny, hairless creature the size of his thumb in his driveway, he had no idea what it was. So, he took it inside, wrapped it up to keep it warm and started Googling. After figuring out it was a newborn squirrel that had probably fallen out of its nest, he put it back outside in a shallow box and waited to see if the mom would return for it. She did come to check it out, but then left it again. (Later, Milburn would find out that the baby squirrel had a mouth deformity which most likely made it unable to suckle properly.)

Milburn didn't think the wee one would survive, but he decided to do his best. He took it back inside and began feeding it puppy formula with a syringe every three hours, around the clock. He said it was "like having a newborn baby in the house." It worked. The squirrel grew and grew and they began to bond.

Once Milburn knew the babe was going to make it and could identify it as a male, he named him Bobby (Robert T. Squirrel, to be precise—the T is for "The"). Milburn shared the story of Bobby's rescue and their relationship with Newsner's We Love Animals channel, and I feel a duty to warn you that the video will almost-pretty-much-for-sure make you want a pet squirrel.

Milburn shared the video on his TikTok channel dedicated to Bobby, where it has collected more than four million views.

Watch:

From an interview on Newsner who has 30 million followers in 11 languages

But that's not where the story ends.

Bobby has a family now out in his little squirrel house. He and his squirrel wife, Barbara Ann, are the proud parents of four youngsters—Peepers, Jeepers, Creepers and Sneekers.

"Peepers seldom ventures from the treehouse, and Jeepers is a bit more adventurous. Creepers creeps out further, and Sneekers sneaks into other trees," Milburn shared on his website, BobbySquirrel.com.

Milburn's @robertsquirrel TikTok channel has a trove of sweet videos like this one, in which Bobby came inside because he was scared of a thunderstorm.

He knew just where to go for safety and comfort. Too sweet.

Bobby is totally comfortable going back and forth from his outdoor home to his human's home—and his human's pockets.

In fact, Milburn shares, Bobby comes to visit him inside almost every day.

Unfortunately, Milburn has run into some trouble with his HOA, which informed him that he needed to stop feeding the squirrels in his yard as they were considered a "nuisance."

But who could watch Bobby listening to his story being told in the video below and tell us he's a nuisance? Come on now.

@robertsquirrel

Happy time #bobbysquirrel #throwbackthursday #squirrel


Milburn has been asked if squirrels make good pets, and he has clarified that raising one as a newborn is very different than trying to domesticate a wild squirrel. Squirrels do have sharp teeth and long claws, he pointed out in a video with this face covered in Band-Aids. (He shared that he's been working on building a friendship with Barbara Ann, who grew up in the wild, and while it's slow-going, he feels he's making progress.)

Milburn has also created a children's book called Bobby and Friends, which includes 10 short stories for children ages 2 to 11 and an accompanying coloring book.

People can't get enough of Bobby the squirrel, and who can blame them? He's the pet squirrel most of us wish we could have—one who has a full outdoor life as he should, but who also likes to come in for some cuddles with his people.

In September 2024, Milburn published his second "Bobby book" entitled The Squirrel Who Lives in the Big Oak Tree, a picture book that retells Bobby and Ron's story.

But that's not all. In partnership with Mystic River Productions, Bobby's got his first movie production, Beyond Detention, under his belt. Written by Milburn and starring Arthur Wahlberg and some new up-and-comers, Bobby's first movie was released on February 6, 2025 with BayView Entertainment and chronicles "seven stranded delinquents" sentence to a wilderness challenge on a remote island. The film is available on Amazon Prime and can be streamed for free on YouTube and Fawesome.

What will Bobby do next?

This article originally appeared two years ago.

The last man on earth and a perplexed chimp.

It’s upsetting for many to consider that humans may not be around one day. But it’s not shocking, given the damage that we’ve done to the planet through climate change and the fact that we’re the only species to create a nuclear bomb. Even if we don’t do ourselves in, the odds aren’t in our favor of the Earth not finding a way to eliminate the surface disturbance known as humanity. Studies show that since life began on Earth, 99% of species have ever lived have gone extinct.

So, after the last human on Earth passes away, who will take over the mantle of being the apex predator and build Earth’s next great civilization? University of Oxford professor Tim Coulson has posited that a rather unorthodox species, the octopus, will take over after we’re gone. His new book, The Universal History of Us, outlines his thinking for the cephalopod takeover.

What species will take over the Earth after humans are gone?

Most people would think that the great apes are our natural successors. Still, Coulson says otherwise. “Hominids such as chimpanzees and bonobos are intelligent animals with opposable thumbs, tool-using abilities, and, at least for short distances, the capacity to walk on two legs, traits shared with us,” Coulson told The European. “Despite these similarities, they would likely face extinction alongside humans, as they are equally exposed to threats in our shared environment.”

Coulson says intelligent birds will fail to take over after humans because they “lack the fine motor skills needed to construct a civilization." However, octopuses have the physical, mental, and social possibilities to build a great society, especially without humans to thwart their efforts.

“Their ability to solve complex problems, communicate with one another in flashes of color, manipulate objects, and even camouflage themselves with stunning precision suggests that, given the right environmental conditions, they could evolve into a civilization-building species following the extinction of humans,” Coulson said. “Their advanced neural structure, decentralized nervous system, and remarkable problem-solving skills make several species of octopus well suited for an unpredictable world.”

Coulson believes that octopuses could evolve to create a great civilization beneath the sea that rivals the world created by humans. With some help from evolution, they may also learn to adapt to life on land and take over where people left off. This may sound improbable, but 370 to 390 million years ago, the first sea creatures left the ocean to live on dry land. Further, some animals, such as dolphins and whales, started in the ocean, lived on land, and then returned to the sea after disruptions to their habitats. Could a similar disruption cause the octopus to look for a better life on the beach?

Culum Brown, a professor in the School of Natural Sciences at Macquarie University, is skeptical that octopuses have it in them to make the big leap to the top of the evolutionary heap. “Despite all their tricks, octopuses are still working from a snail blueprint, and there’s only so much you can do with that toolbox. They are also highly constrained by their very short life-span,” Brown wrote in The Conversation.



Sydney Philosophy of Science Professor Peter Godfrey-Smith told Popular Mechanics that octopuses are also hindered by their social dynamics and lack of “intergenerational connections.” Given that they have yet to develop them over millions of years of evolution, Godfrey-Smith is doubtful they’ll occur “anytime soon.”

It’s impossible to know what the future holds, but don’t be shocked if, one day, octopuses develop a superior civilization based on peace, love, and seaweed. “Random mutations, unforeseen extinction events, and population bottlenecks can all significantly influence the trajectory of evolution, making it challenging to determine whether another species will develop human-level intelligence or the inclination to construct cities,” Coulson told The European. “But could octopuses replace humans–and potentially also primates–if they were to die out? Absolutely. They could become the brains of the sea.”
