Introduction
In this thrilling episode of Who Smarted?, titled "How Likely is it for Earth to be Hit by an Asteroid?", host Atomic Entertainment delves deep into the fascinating world of asteroids. Tailored for curious young minds and their families, the episode combines humor, storytelling, and scientific insights to explore the origins, behaviors, and potential threats posed by these celestial rocks.
Understanding Asteroids
The episode kicks off with an engaging metaphor, comparing the iconic drumbeats of Queen’s "We Will Rock You" to the literal rocks from space that occasionally collide with Earth.
- Host [00:03]: “Psst. Smarty pants. Hear that? That could be the opening stomps and claps from the rock song We Will Rock You by Queen. Or it could be the sound of rocks from space smashing into Earth.”
Listeners quickly grasp that asteroids, often perceived merely as "rocks," are dynamic entities within our solar system.
Impact on Earth: Then and Now
The host highlights historical and recent asteroid impacts to illustrate their varying degrees of influence:
- Host [00:33]: “These rocks, known as asteroids, hit Earth all the time. Sometimes it's hardly noticeable. Sometimes it causes a sonic blast powerful enough to shatter windows and injure people. Like the asteroid strike in Russia in 2013. And sometimes it completely changes the planet, wiping out entire species. Like the asteroid that caused the dinosaurs to go extinct 65 million years ago.”
A playful exchange underscores the dragon-like consequences of these impacts:
- Listener 2 [00:25]: “And we will. We will get rocked by you.”
Origins and Characteristics of Asteroids
The discussion transitions to the origins of asteroids, primarily focusing on the asteroid belt between Mars and Jupiter.
- Host [02:15]: “As you may know, our solar system consists of one sun, eight planets, several dwarf planets, and lots and lots of rocks. These rocks, or asteroids, can be found throughout the solar system, sharing orbits with some planets, including Earth.”
The host explains the vast number of asteroids and their sizes, providing relatable comparisons to help young listeners visualize their scale.
- Host [03:37]: “A bag the size of the Earth would also be too big. And believe it or not, if you put all the asteroids together, you still wouldn't fill a bag the size of the moon.”
Asteroids Vesta and others are mentioned to emphasize the diversity in their sizes.
Asteroids as Characters: Petey and Star
Infusing personality into asteroids, the characters Petey and Star interact with the host, challenging the simplistic view of asteroids as mere rocks.
-
Petey [04:16]: “Ahem. Beg your pardon, bub. I couldn't help but overhear you keep referring to asteroids as rocks.”
-
Star [04:25]: “Yeah, we're not just rocks.”
They express their uniqueness and the necessity for recognition beyond being faceless celestial objects.
Frequency of Asteroid Strikes
A pivotal segment addresses the likelihood of asteroid impacts on Earth, dispelling common fears with scientific facts.
-
Host [08:08]: “On average, how often do asteroids strike Earth? Do you think it's A, once every million years, B, once every hundred years, or C, almost every day?”
-
Host [08:23]: “A lot of them remembered me saying earlier that bits of asteroids hit the Earth practically every day. These little bits burn and break apart in the atmosphere, so they don't usually reach the ground.”
It is clarified that while tiny meteoroids enter Earth's atmosphere daily, significant impacts are exceedingly rare.
- Host [09:05]: “Scientists say asteroids big enough to cause a global disaster only strike once every 100,000 years. So right now, it looks like we're all gonna be just fine.”
Planetary Defense: Protecting Earth
The episode reassures listeners about Earth's defenses against potential asteroid threats.
- Host [09:21]: “NASA is always on the lookout and has defense plans just in case. If an asteroid is spotted heading towards Earth, we'd use spacecraft or weapons to break it apart or nudge it off course.”
The practicality of intervention methods, such as rockets or missiles, is explained to mitigate fears.
Asteroids' Positive Contributions
Challenging the predominantly negative portrayal, Petey and Star shed light on the beneficial roles asteroids have played:
-
Petey [14:45]: “Way back when the solar system was first forming nearly 5 billion years ago, asteroids and other space objects called comets was zipping around everywhere. Some of these may have brought water ice and other molecules necessary for life to Earth.”
-
Star [15:59]: “Asteroid strikes can help scientists learn more about the beginnings of the solar system.”
These insights highlight the essential contributions of asteroids to Earth's development and scientific knowledge.
