Professor breaks down why Earth’s interior core might perchance presumably perchance even have stopped


Well, this morning we are learning about a shift in the Earth's inner core. That sounds like the plot. The Hollywood blockbuster. Scientists say our planet solid which is actually disconnected from the rest of the Earth's lay may actually have stopped rotati.

And could even reverse course. This is a new study. It was published Monday in the journal Nature Geoscience, and its authors who are based in Beijing, took a very close look at the seismic waves from earthquakes.

That have passed through our planet's core since the 1960s. And that is how they were able to calculate the speed at which the inner core is spinn Are you confused? I am. We're going to.

Get to understand this a little better with our guests. Let's bring in Michio Kaku. He's a professor of theoretical at the City University of New Yo Professor, good morning. Thank you. Morning. Glad to be o What does this mean? Well, at first.

It sounds like something from a Hollywood movie script says, oh, my God, the core of the earth is spinning backwards. I mean, this is worse than having a tsunami or an eart The stability of what you walk o.

Is at stake. Now, this report comes not from Hollywood. It comes from reputable scientis at Beijing University. They analyze echoes when an earthquake takes place. Shock waves go reverberating.

Around the inside of the earth. And by analyzing these echoes with computers, you can recreate a model of the of the earth. And sure enough, the course seems to be about to spin backwa But I read that this happens.

Every 70 years, so we don't need to be alarmed. That's right. The bad news is that we know ver about the core of the Earth, very little about what's underne our feet. The good news is probably there's nothing to worry about.

In the sense that roughly every seven years o we're not sure the the the center of the earth does seem to go backwards. If this is the core, this is the crust, of the earth that we live on. Yes.

This is the core of the Earth. The core could move independently of the crust. That's the key. So the point we're on never move in reverse. Yeah. So the core of the Earth system and a pool of, like, molasses, and it's able to spin.

Independently of the crust of th So, in other words, don't lose any sleep over this probably is a natural cycle. It takes place probably once every 70 years or so. But we need more data because this is new territory fo Yeah. Why do we need to know?.

I mean, they spent a lot of time They studied earthquakes back to the sixties. Why is it important to know more about this what are the implications? The implications are potentially because think of continental dri Why are the continents moving aw.

From each other? What is driving it and also eart The whole nature of the stability of the planet i We know very little about what's underneath our feet And that's why this information from from Echo' computer analyzes is very import.

Because it tells us the future of the Earth. What questions? Finally, Professor, does this leave you with? Well, it leaves me with the frus The head is under our feet. Is this you can you can almost touch it,.

But it is thousands of miles dis And we really don't know that much about our home. We know more about other planets than we do about the center of the Earth thing, like Mars, for example, is probably frozen over. Not much earthquake activity at.

So we know a fair amount about M We know very little about the Ea because the Earth is dynamic Things are moving and churning at the center of th That's why we have earthquakes. That's why we have continental drift and volcanoes. Yeah. Volcanoes. My son's favori.

Oh, he likes to make it with baking soda and vinegar in the kitchen. Thank you, Professor. I now understand it much better. Appreciate it.

Sharing is caring!
