How the Universe Might End

Thu, 26 Jun 2025 16:14:41 +0800

video duration is 2:59. Right now, the universe is full of life and light. But over unimaginable spans of time, everything we know will end. Galaxies will fade, stars will die, and even black holes will disappear, leaving behind a cold, dark void. This is the timeline of the universe's death.

Why Do Planets Rotate in a Disk?

Thu, 19 Jun 2025 14:00:18 +0800

video duration is 1:0. Why do all planets orbit in the same flat plane? Let's travel back 4.5 billion years to the formation of our solar system, when a giant cloud of gas and dust collapsed.

A war has been raging for decades in the jungles of Panama, as we fight one of the most terrifying parasites on Earth. It is so relentless that our best defense is to drop 100 million radiation-blasted, flesh-eating flies from the sky – every week.

It’s one of the most successful biological campaigns in history, but it’s a war we can never stop fighting… and one we can’t afford to lose.

Fentanyl is the deadliest illegal drug in US history by far. It’s often described as the ultimate high, but it’s actually an inferior, short-lived, and brutally addictive version of heroin. In this video, we explore what opioids do to your brain and body, what it feels like to take them, and why so many people are dying from Fentanyl overdoses without ever choosing to take it.

Panic Attacks Explained in 60 Seconds

Thu, 15 May 2025 14:01:09 +0800

❓What is a panic attack?

A panic attack is an episode where a person experiences a sudden wave of fear and anxiety, often in a situation where there is no real threat or danger. They can be triggered by stress, a shocking life event, or even too much nicotine, caffeine, or alcohol. Around one in three of you could suffer from a panic attack at least once in your life. Panic attacks are accompanied by physical signs and symptoms of anxiety and can include a rapid heart rate, feeling short of breath, feeling one is losing control, feeling detached from one’s body or reality or even feeling like one might die. Even if it feels awful, know that the panic won’t physically hurt you and that the attack will pass.

❗Things that can help during a panic attack:

1️⃣ Breathe.

Practice abdominal breathing: Breathe slowly from your abdomen through your nose to reduce symptoms of hyperventilation

2️⃣ Stay in the present.

Staying in the present and focussing on external objects will help minimize the attention you might give to troublesome physical symptoms or catastrophic thoughts. If possible, you might try actually touching objects nearby to reinforce staying in the immediate present or use the 5-4-3-2-1 exercise: 5: FIVE things you see around you. 4: FOUR things you can touch around you. 3: THREE things you hear. 2: TWO things you can smell. 1: ONE thing you can taste.

3️⃣Know it will pass.

Even if it feels awful, know that the panic won’t physically hurt you and that the attack will pass.

4️⃣Be kind to yourself.

It’s okay to be scared, and you’re not alone. Practice positive self-talk and self-compassion to help reduce anxiety. You are stronger than you think and you can handle this. 💖

Heat Affects Who Gets Born

Thu, 01 May 2025 14:00:28 +0800

In some animals, heat determines whether babies are born male or female. In a warming world, this natural system might break, and some species are already at risk: Some species are seeing way fewer males.

But at least there are good news: Larger spiders! 🤗✨🕷️👌

Why Do We Itch?

Thu, 17 Apr 2025 14:00:44 +0800

Why do we itch and why does scratching feel so good? Itching evolved to protect us, but for 1 in 5 people it can become chronic, making them feel like they’re constantly under attack by fire ants.

SOUTH KOREA IS OVER

Wed, 02 Apr 2025 14:00:03 +0800

Sources & further reading:

https://sites.google.com/view/sources-korea-is-over/

South Korea is heading toward a demographic collapse unlike anything the world has seen before. With the lowest fertility rate ever recorded and a rapidly aging population, the country faces a future of economic decline, shrinking cities, cultural erosion, and a vanishing workforce.

By 2060, nearly half of South Koreans could be over the age of 65, and entire regions may be abandoned as the population continues to shrink.

How did South Korea reach this point? Why might it no longer be possible to reverse the trend? And what does this mean for other countries on a similar path?
