When you are in the center of the earth, you have 6,000 km of rock pressing on you from all sides. But if you drill a hole (as a thought experiment, because it is technically impossible), you will have a free space in the center, say 10 x 10 x 10 meters. Will you still be squeezed together in that free space? Some say no: you will float in the middle, others say yes, because you are not squeezed by the 6000 km of rock, but by the space-time curvature, which is still maximally present at the center. Hard to imagine, and we may never know. Where is the physicist to explain this?
@@roelfbackusWell Roelf, I've arrived. That is a very interesting thought experiment. Cheers. I'm not too sure about the journey downwards, as the valve of (g) - the acceleration due to gravity would increase, or would it? _(the radius would decrease, but so would the mass beneath your feet!)_ However, as a part-time physicist, I can say this with some confidence...At the very centre of the Earth, we would not experience any action from a tidal force, gravitational attraction or centrifugal effect, because we would essentially be weightless, in a freefall motion, around the common centre of mass, in the Earth-Moon system, but we would still witness the oceans, as ever-so-slightly accelerating away from us in either direction, on its surface. Does that help with your visualization in anyway? Thank you kindly.
I just wonder how would we know this information about the center of the earth like temperatures, minerals, and other stuff when we still can't get through the first layer?
Great question! While we've only been able to directly observe the Earth's outermost layer, there have been amazing advances in scientists' ability to gather indirect data about what's underneath it. I'm still learning a lot about it myself, but look into a method called seismic topology, which is essentially measuring the velocity at which seismic waves move through various materials. I'm sure seismologists and other geologists would be much better at answering this, but hopefully you can find the answers you're looking for!
Ive watched somewhere wherein Scientists study the Earth's core using indirect methods like seismic waves, meteorites, laboratory experiments, magnetic fields, and computer modeling.
Perhaps there is a meeting line between gravity and electromagnetism, or where we can mimic what the Earth does so that we dont get crushed. Like the electromagnetic force field and witht the atmosphere’s structure
I have a question that I would like someone to answer I may ask when u Skuba dive and u do deeper and deeper and deeper it gets cold right so in the middle of the earth there is like say a hot ball and when u get deeper isn't it supposed to get hotter or am I tweaking I would be grateful if you answer this and thanks for telling about the world it seems cool and fun knowing what's inside what we are living on! have a good day.

Three minutes to the centre of the Earth - BBC 1304pm 2.8.23 so 40ft is the deepest any animal burrows as a shelter....? i mean you mentioned worms at 2km down... so we await the day they do drill in to the mantle - which is akin to a bunch of kids undertaking some act just to see what happens....
You are absolutely right. Earth can become a star, if its mass constantly gets increased by asteroids or space dust. There is a natural size limit and if a planet exceeds that limit it will start to become hotter and hotter and eventually become a star. But if a planet doesn't grow in size any more, then it core will cool down one day and will stop emitting more heat because all the atoms in the core will have fused into iron or other denser metal, depending on the size of the planet. For example the core of the biggest star will be the densest metal we might have not discovered yet. The densest metal on earth found is Osmium or maybe there is other which I may not know yet. Every metal we use here was once a part of a star or planet.
Temperature is vibration, not Heat. Heat, is energy. There's nothing difficult about making molecules at the centre of the Earth vibrate - that's why they have a temperature. High temperatures can destroy solid state magnets - but that's nothing to do with the Earth's core. The core produces a magnetic field as a result of the geodynamics of liquid iron - something which is only possible _because_ the Earth's core is at a high temperature... What exactly are you saying, here?
Where are all the multiple kilometres of open space and water and vegetation and all the lost DINOSAUARS?? Such a shame that truth rules imagination... M 🦘🏏😎
This was best thing I ever watched about earth stuff , like damn , I felt amazed and was Interested the whole time !!!!
That was pretty cool
Great story telling, great animation 😊💛🌿

The surrounding rock will collapse upon you and crush you.
@@jimsagubigula7337 a thought experiment !

I wonder, how the gravitational lines will disappear in the center.

@@wavydaveyparker Thanks for your explanation, but how about the time-space curvature in the center? Is it a hoax?
I just wonder how would we know this information about the center of the earth like temperatures, minerals, and other stuff when we still can't get through the first layer?
Agree. Why would they know that the inner core is made of metal?

If only Sir David Attenborough were the narrator for this video because it's hard to tolerate the voice.
I don’t think it’s her voice, I think it’s the entire childish presentation.
I feel very amazing after I watch this video. ❤ Nice..

I felt bad for the driver. He made it out or still in there? Any update?
Atoms get bent, deep inside the “Erf” LOL

😂😂😂 bro y’all don’t even know what’s at the bottom of the deepest oceans. Htf y’all gonna know what beneath the deepest oceans 🤦♂️
This video is clearly not real. It is obviously an animation and not actual footage of the center of the earth.
Duhhhhhh 😅
Suspension of belief. I, for one, salute our Mole underlords 🐊
I have a question that I would like someone to answer I may ask

This narrators voice is unbearable!
I don't like the narrator. I can't understand what they are saying.
Proud to be the first to comment
Except you're not.
Earth looks like a failed star
NO.
EARTH is a PLANET.
Learn the difference between a star and a planet.

driver is a she?
Why NOT?
That's all proves of a creator not an evolution or BigBang.
It just just shows you how mass and the maths behind it works, nothing really to do with creator or evolution
Who created the creator (it's female by the way) ?
care to explain? because right now it just seems like an explanation of the planet's insides.
Heat is vibration, and it is difficult to make the molecules in the center of the Earth vibrate. 📳
High temperatures demagnetize...🧲

the lost dinosaurs are buried under layers of the crust. the multiple kilometres of open space and water and vegetation are on top of it.
