More than 65 million years ago, the mighty dinosaurs ruled the Earth — until one day, they vanished forever.
In this week’s episode of Smart Talks with Raj, we dive deep into one of the biggest mysteries in natural history: Why did dinosaurs go extinct?

🎬 Watch the Episode
🧠 Quick Summary
This episode explains how a giant asteroid impact changed life on Earth forever.
Raj explores how the Cretaceous–Paleogene extinction wiped out nearly 75% of Earth’s species — including the dinosaurs — but also opened the door for mammals (and eventually humans) to thrive.
It’s a fascinating look at how destruction can also bring new beginnings.
💡 Key Takeaways
☄️ Around 66 million years ago, a massive asteroid struck near Chicxulub, Mexico, triggering global chaos.
🌋 The impact caused wildfires, earthquakes, and volcanic eruptions, blocking sunlight and cooling the planet.
🦖 Without sunlight, plants died — and soon after, the dinosaurs followed.
🧬 But their extinction gave rise to new forms of life, eventually leading to us.
🧩 Did you know? Scientists believe birds are actually the last surviving group of dinosaurs, known as avian dinosaurs!
🗣️ Talk About It
Here are a few questions to explore after watching the video:
What do you think was the biggest reason dinosaurs couldn’t survive?
If the asteroid hadn’t hit Earth, do you think humans would exist today?
Which dinosaur do you wish could come back to life?
⚙️ Behind the Scenes
This episode was inspired by Raj’s curiosity about how such powerful creatures could just disappear.
Creating the visuals of asteroids, volcanoes, and dinosaurs helped bring ancient history to life — showing that science is not just about facts, but imagination too.
Raj wanted young viewers to feel awe — not just for dinosaurs, but for the forces of nature that shape our planet.
