In this episode of All The Things, Travikiss breaks down one of the strangest truths in physics — time doesn’t move the same everywhere. The closer you are to gravity, the slower time moves.

Using the famous scene from Interstellar, we explore how time dilation actually works in the real universe. The same effect that made Romilly age 23 years while the crew experienced only 3 hours is also happening on Earth — even across the length of your own body.

And it’s not just a weird physics trick…

If scientists didn’t correct for time dilation, the GPS in your phone would drift about 7 miles every single day.

In this video we cover:
• Why gravity slows down time
• The real physics behind the Interstellar time dilation scene
• The experiment where scientists proved time moves faster higher above Earth
• Why GPS satellites must correct for time every day
• And the mind-bending truth about how gravity bends the fabric of time

This isn’t science fiction.
It’s the physics that quietly runs the modern world.

🧠 About This Video

In this episode of All The Things, we break down the Middle East — and why one tiny stretch of water could send shockwaves through the entire global economy.

Most people hear “Middle East conflict” and immediately tune out because it feels confusing, ancient, and impossible to untangle. But under all the headlines, there’s actually a very clear structure: oil, religion, power, and geography.

This video walks through the key countries, leaders, rivalries, and alliances shaping the region right now. It explains why the Strait of Hormuz matters so much, why the region keeps pulling global powers into its orbit, and why the death of Iran’s Supreme Leader may trigger a major shift in what happens next.

What you’ll learn:

• The big idea: The Middle East isn’t random chaos — it’s a geopolitical chessboard driven by oil, religion, geography, and power.

• Why it matters in real life: A huge portion of the world’s oil moves through one narrow choke point, so conflict there can hit gas prices, global markets, and international stability fast.

• The surprising part: A lot of the fighting isn’t country versus country in the traditional sense — it’s indirect, through militias, proxies, and shadow alliances.

• The takeaway you’ll never unsee again: Once you understand the players and incentives, the Middle East stops looking like chaos and starts looking like a system.

In this episode of All The Things, we break down one of the most complicated geopolitical stories in the world right now — Iran, nuclear weapons, and the escalating conflict with the United States.

For decades, the relationship between the U.S. and Iran has moved from allies… to bitter enemies. Sanctions, revolutions, proxy conflicts, nuclear enrichment, and failed diplomatic agreements have all played a role.

This episode walks through how we got here, from the 1979 Iranian Revolution, to the 444-day hostage crisis, to the 2015 nuclear deal, and finally to the major escalation in 2026.

The goal is simple:
Cut through the headlines and explain what actually happened and why it matters.

What you’ll learn:

• The big idea: Iran’s nuclear program sits at the center of global tension because uranium enrichment can power cities or build nuclear weapons.
• Why it matters in real life: Decisions made by a few leaders can affect millions of people across the Middle East and the rest of the world.
• The weird/surprising part nobody tells you: The U.S. and Iran were actually close allies before 1979.
• The takeaway you’ll never unsee again: The conflict today didn’t start yesterday — it’s the result of almost 50 years of escalating events.

Check out the full version to see more about multiple sclerosis.

In this episode of All The Things, we break down what’s actually happening when someone gets diagnosed with Multiple Sclerosis — without the internet horror stories.When people hear the words “you have MS,” their brain immediately jumps to worst-case scenarios: wheelchairs, disability, and life falling apart. That’s exactly what happened to me in 2013. But the reality is far more nuanced — and a lot more hopeful — than what Google will tell you at 2 a.m.This episode walks through the science of MS, the strange symptoms that lead up to diagnosis, and the mental spiral that almost everyone goes through in the beginning. Most importantly, it explains what modern treatment actually looks like and why a diagnosis today is very different from what people imagine.

What you’ll learn:• The big idea: MS happens when your immune system mistakes the myelin coating on your nerves as an enemy and starts attacking it.

• Why it matters in real life: Understanding what’s happening in your body takes away a lot of the fear — and helps you focus on the things that actually matter: treatment, lifestyle, and moving forward.

• The weird/surprising part nobody tells you: Many people with MS live completely normal lives once they start effective treatment. The internet rarely shows you those stories.

• The takeaway you’ll never unsee again: MS may become part of your story — but it does not get to decide how that story ends.

Ever had someone point out something obvious you completely missed? That's not carelessness—it's change blindness, one of the most fascinating limitations of human perception. This video explores why your brain creates a convincing illusion of seeing everything around you, when in reality you're only processing a tiny fraction of your visual environment. From the famous Invisible Gorilla experiment to real-life examples like missing a six-foot Christmas tree, discover why your brain operates on a "just-in-time" system that prioritizes efficiency over accuracy. Learn about the neuroscience behind this phenomenon, why magicians exploit it, what this means for eyewitness testimony, and why missing obvious changes doesn't mean you're unobservant—it just means you're human.

What if the most important part of your brain isn’t a neuron… but the tiny space between them?For decades, scientists fought over whether neurons were fused together into one continuous web, or whether they were separate cells with gaps between them. That debate—between Camillo Golgi and Santiago Ramón y Cajal—became one of the biggest feuds in neuroscience history.The answer turned out to be a gap just 20–40 nanometers wide: the synapse.In this video, we explore:The rivalry that shaped modern neuroscienceHow scientists discovered the synapseWhy this tiny gap is the foundation of learning, memory, and changeHow synaptic plasticity literally reshapes your brainEvery thought you have, every memory you form, and every skill you learn depends on signals crossing these microscopic gaps. In a very real sense… these tiny spaces make you you.If you enjoy deep dives into the brain, learning, and what makes us human, consider subscribing. We put out videos like this every week.

Right now, invisible waves of air pressure are hitting your ears — and somehow, you’re hearing sound.But here’s the wild part: sound doesn’t actually exist outside your head.What exists are pressure waves moving through air. Everything else , pitch, volume, direction, emotion, is something your brain constructs in real time.In this video, we break down:How your eardrum detects movements smaller than an atomWhy three tiny bones act like an amplifierHow your cochlea turns vibration into electrical signalsHow your brain rebuilds sound from raw neural codeAnd why hearing isn’t passive, it’s your brain actively creating realityThis is one of the most impressive tricks in biology, and it’s happening inside you every second.If you like deep ideas explained clearly, this channel is for you.

Have you ever arrived home and realized you don’t remember the last 15 minutes of the drive?This video explains highway hypnosis, what neuroscientists call automaticity. It’s the process that allows your brain to perform complex tasks like driving, walking, reading, or typing without conscious effort.You’ll learn how control shifts from the prefrontal cortex (your brain’s “CEO”) to deeper structures like the basal ganglia and striatum, where habits and automatic behaviors live—and why this actually makes you safer, not more dangerous.

Our ancestors faced a real threat from snakes. They adapted over generations, evolving a unique system to detect these silent predators. Evidence shows that primates have sharper vision and a more complex visual cortex than others, all thanks to this evolutionary pressure.

This snake detection system works through a quick shortcut in our brains, bypassing conscious thought. When we see something snake-like, our bodies react before our minds even register it!
