Zac Efron has been traveling around the world frequently since he shot to fame, both for work and leisure. Still, he kept living in California, where he was born and raised. However, it all suddenly changed after he chose to spend some time abroad and he realized he needed to change the way he lived in order to find true happiness.
He lived most of his life in the United States.
Originally from San Luis Obispo, in California, Zac Efron spent the majority of his life in the United States, having grown up close to the heart of Hollywood. Despite this, his parents were never involved in the entertainment business. Still, he took his first steps into that world early on in his life. His journey in acting and singing began during his time at Arroyo Grande High School in the early 2000s, with a drama teacher playing a pivotal role in connecting him to an agent.
After he achieved success with teen flicks like the High School Musical trilogy and 17 Again(2009), he shifted into more dramatic roles in films such as The Greatest Showman(2017) and, more recently, Extremely Wicked, Shockingly Evil and Vile(2019). It was this ever-growing filmography that allowed him to amass a net worth of around $25 million and gave him the opportunity to purchase a mansion in Los Feliz, Los Angeles, in 2013. He lived there for seven years until he no longer felt like it was the right place for him.
So, what happened to Zac Efron to make him change his mind? Keep reading to find out.
His L.A. house had everything to offer, but ultimately it wasn’t enough.
The 36-year-old actor put his Los Feliz home up for sale in December, 2020, and the listing made public the house’s astounding features. The property, which is nestled against the Hollywood Hills and located in a prestigious neighborhood filled with plenty of celebrity residents, offers breathtaking views, accentuated by walls of glass, terraces, and numerous outdoor spaces that offer panoramic vistas of the city below.
With five bedrooms and five bathrooms within its 5.455-square-foot layout, the main level includes a living area, dining room, chef’s kitchen adjoining a family room, and a master suite with a spa-like bathroom. But that’s not all!
Additionally, it has three bedrooms with bathrooms downstairs, along with a separate one-bedroom, one-bath guesthouse. It also features amenities such as a gym, media room, game room and security cameras, and the outdoor space includes view decks suitable for outdoor dining and lounging.
So, with all its potential, it wasn’t shocking that it sold in only a few months, in spite of the hefty price tag. In May 2021, the house sold for $5.3 million. Albeit below the initial asking price of $5.9 million, it still marks a profitable venture for Efron, as he paid around $4 million when he first purchased the property.
He fell in love with a different country.
In 2020, Efron made a move that had a deep impact on him — he relocated to Byron Bay, Australia. Back then, he still owned the Los Feliz mansion, so many thought it was just a temporary home. The fact that he lived out of a van, before buying a property in the Australian beachside town also led many to believe nothing much could come of the move.
However, he shot the second season of his Netflix documentary series Down to Earththere, which allowed him to spend over a year with the Aussies. Eventually, he did return to the US to enjoy quality time with his family, but it wasn’t long before he was once again on Australian ground. This time, it was to shoot Ricky Stanicky, a movie in which he co-stars with John Cena and that has yet to have a set date for its debut.
But a special situation might have sealed the deal for his ever-growing bond with the country. Shortly after he moved to Australia, Efron found love. He met Vanessa Valladares, a waitress at the Byron Bay General Store & Cafe, in June 2020. They began dating and eventually spent Christmas and New Year’s together in Australia. Although the couple has since called it quits, the relationship might have been the final trigger of Efron’s decision to move permanently from the US, as he then put his L.A. home on the market.
Finally, a source close to the actor revealed in January 2021, that Efron already considered Australia “home.”
The actor doesn’t think Hollywood is a healthy place to live in.
The actor had previously expressed his intention to move out of Hollywood, though, and it was precisely in a scene from Down to Earth. In the fourth episode, he candidly shared his desire to move away from the Hollywood scene and the lifestyle associated with it, and emphasized that it didn’t contribute in any way to a “long, happy, mentally-sound life.”
Curiously, what happened to Zac Efron also happened to Chris Hemsworth, in which both actors made the decision to move to Australia so they could distance themselves from the hecticness of Hollywood. Although Hemsworth himself is Australian, his mindset was similar to that of Efron.
In 2016, Hemsworth, known for his role as Thor in several Marvel movies, relocated his family from Los Angeles to Byron Bay. The 40-year-old similarly expressed a wish to escape the suffocating nature of being constantly surrounded by the entertainment industry. Opting for a more tranquil lifestyle, as of 2023, he and his family reside in a $20 million mega-mansion in Byron Bay’s hinterland, which they view as a healthier environment for their children to grow up in.
People often also wonder what happened to Zac Efron when it comes to his new appearance. His face changed considerably throughout the years but the drastic change isn’t down to plastic surgery. According to him, it’s because of an accident where he almost died.

Synaptic Information Storage Capacity Measured With Information Theory
Ever wondered just how much data your brain can hold? We often compare the brain to a supercomputer, but what if that comparison isn’t just a metaphor—it’s literal? Deep within your brain, at the junctions where neurons meet, lies an extraordinary form of biological storage: the synapse. And thanks to breakthroughs in information theory, we’re beginning to quantify its staggering capacity.
In this article, we’ll dive into how synaptic storage works, how scientists measure it, and why this knowledge could shape the future of data storage—from artificial intelligence to DNA-based memory.
What Are Synapses and Why Are They Important?
Think of neurons as the brain’s messengers. But without synapses—the gaps between them where signals are transmitted—those messages would go nowhere. A synapse is where the magic happens: it’s the space where one neuron sends a chemical or electrical signal to another, sparking thoughts, memories, movements, and more.
Now here’s the kicker: each of these tiny junctions doesn’t just pass along data—it stores it.
Your brain has about 86 billion neurons, and each one can form around 1,000 synapses. That’s a total of roughly 125 trillion synapses buzzing away in your brain, constantly sending and receiving signals. These connections form the foundation of your memories, knowledge, and perception.
Measuring Synaptic Storage with Information Theory
To understand how synapses store information, scientists turn to information theory—a branch of mathematics that deals with encoding, decoding, and compressing data. Think of it like analyzing how much a hard drive can hold, but on a biological scale.

Each synapse, as it turns out, can store up to 4.7 bits of information. That might not sound like much until you consider the scale:
- 1 bit is a single piece of binary data (a 0 or 1)
- 4.7 bits per synapse × 125 trillion synapses = over 500 trillion bits of potential storage
Translated into digital terms, your brain can theoretically store more data than the entire internet—all in a compact, low-energy package powered by biology.
The Brain’s Efficiency: Powering Trillions of Connections
Here’s something even more mind-blowing: while your laptop heats up and guzzles electricity, your brain handles all of this complex storage and processing using roughly 20 watts of power—that’s about the same as a dim light bulb.
This insane efficiency is what’s inspiring researchers to build neural networks and deep learning systems that mimic the brain. If computers could process and store data like synapses do, we’d have faster, smarter, and greener technology.
Artificial Intelligence and Synaptic Models
The field of AI, especially machine learning and deep learning, borrows heavily from how the brain processes and stores information. Artificial neural networks use layers of interconnected nodes (inspired by neurons) to simulate learning.
But here’s where it gets interesting: researchers are now using real data about synaptic information capacity to refine these systems. The goal? To build AI models that are more human-like, not just in intelligence but in efficiency and adaptability.
Imagine a future where your smartphone thinks and stores information with the same elegance as your brain. That future isn’t science fiction—it’s science.
Beyond the Brain: DNA as the Ultimate Storage Device
While the brain remains the pinnacle of biological storage, it’s not the only game in town. Enter DNA, nature’s original information vault.
DNA doesn’t just code for life—it can be used to store digital data. And we’re not talking small files here. A single gram of DNA can hold up to 215 petabytes of data. That’s 215 million gigabytes—enough to store every photo, song, and document you’ve ever owned, plus millions more.
In fact, researchers have already done it. In one groundbreaking study, scientists encoded a 52,000-word book into synthetic DNA. They converted the digital content into binary (0s and 1s), then translated those digits into DNA’s four-letter alphabet: A, T, G, and C. The result? A physical strand of DNA holding a complete, retrievable digital file.
Why DNA Storage Matters for the Future
Traditional storage devices—hard drives, SSDs, even cloud servers—have physical limits. They degrade over time and take up massive amounts of space. DNA, on the other hand, is incredibly compact, durable, and stable for thousands of years if stored properly.
If scaled correctly, DNA storage could revolutionize how we preserve knowledge. Imagine backing up the entire contents of the Library of Congress on something no bigger than a sugar cube. That’s the level we’re talking about.

Bridging Biology and Technology
What’s exciting is how these two areas—brain synapses and DNA storage—are starting to intersect. Both are nature’s proof that small-scale systems can handle mind-blowing amounts of data. As scientists continue to decode these systems using information theory, they’re finding ways to integrate them into technology.
It’s not about replacing computers with brains or turning DNA into a USB drive. It’s about learning from nature’s most efficient designs to build the next generation of computing and storage systems.
Conclusion: Reimagining Storage in a Biological World
Your brain’s 125 trillion synapses silently store and process more information than entire server farms, all while sipping on 20 watts of energy. Meanwhile, DNA—the code of life—is showing us how to pack massive libraries of data into microscopic strands.
By measuring synaptic storage capacity with information theory, we’re not just understanding the brain better—we’re laying the foundation for a new era of intelligent, efficient technology.
The takeaway? Nature has already solved problems we’re only beginning to understand. And the more we study it, the closer we get to unlocking the true potential of both our minds and our machines.
