Hikaru Gabriel Kuboyama won't work you have to apply the pressure at a rate faster than it can radiate the heat that is being pressed in together. Or you need friction which dies out, aka it loses its heat and solidifies, without an external force or electron source.
I imagine you are being sarcastic though as you were taught physics in school. Yes or no? First answer about the sarcasm second on what they are teaching.

RoarOfDamnation Unfortunately, we'll have to wait until well after the death of the sun for the Earth to cool off, so maybe those people want to consider that before commenting :)
What would happen if you "touched" the end of the Universe. If you were somehow traveling as fast as the expansion of the Universe, and caught up. Could you touch it? And would it burn? Could you go threw it?
what if you are misinformed, what if outer space is a hoax and we live in a dome on a flat earth? and not just what if, but you look this up find out it's the truth, you still want to touch the imaginary expanding universe, or do you want to touch the edge of the dome over Antarctica, what if you can't find the edge of the dome over the ice and you find another 🌞 circling a world you never heard of. but that's just the real theory of where aliens might come from, because you sure as hell can't go to the moon. you can't orbit earth either.
+Alwin Priven it's flat, how that is so hard for sheeple to understand is beyond me, but you might learn something if you open your mind and see through the lies instead of believing the lies. go stack 16 million pennies and watch the bottom one turn to liquid, if you believe this moron in the video. you have eyes and access to internet, Seek and you shall find, ask, and your questions will be answered. just don't ask me, I don't have time to talk to children about 🎅 Santa. it's messed up that we are lied to, but it's because we are invaded by an evil presence that is not human. demonic or other I can't be sure. but flat earth is easy to prove a fact.
What about an episode exploring the science of zombies? Considering the surge of interest in recent times, it could make for an interesting video. You could talk about stuff such as Cordyceps and tetrodotoxin, or whether the idea of walking dead people is even phisicly possible?
Uranium is the 7th most abundant metal in the earth's crust. The radioactive decay of this uranium is a supplemental heat source in the crust and part of the driving force behind plate tectonics. The extremely slow cooling of the earth mentioned in the video is for the much larger remaining mass consisting of the mantle and the core over billions of years. The atmosphere and the earth's immediate crustal surface is largely heated by solar radiation. The crust can and will continue to warm with time as the increases of CO2 and methane in the atmosphere only serve to retain surface heat better and for longer periods of time during the year. The earth's surface essentially heats up because the atmosphere is now better at retaining heat or a is better insulator as a result of the increasing CO2 and methane levels. Heat loss from the core and mantle has to pass to the crust before it can radiate into the atmosphere and be lost into the vacuum of space.
We have Read about China digging a deep hole into earth. Diameter of earth is 7,917.5 miles. So, for the Present, from there, try to go horizontal somehow and come back in an inverted mug shape...altogether for 30 (10+10+10) Miles. Keep Repeating such tactic at the periphery until technology develops, enabling reaching all the way to the other end of the earth safely !
Call me stupid or whatever, but I never thought of earthquakes as being part of the cooling process. I always thought it was plate tectonics. Let me guess, same thing, or all one process? I know the mantle is still cooling, but never thought of the results of cooling 'up here'. Yeah, I'm not a scientist guy or anything, but I like science.
To clarify that a little: Earthquakes are not CAUSED by the cooling or contracting of the Earth, they are due to friction and collision thanks to plate tectonics. But you can look at Earthquakes as Earth working toward an eventual steady state someday in the far future, with heavy, cooler stuff working toward the core. When an Earthquake happens, the mass of the Earth is redistributed ever so slightly in a way that lowers Earth's moment of inertia (like a figure skater drawing in their arms) by concentrating a bit more mass toward the center, and causes it to spin ever so slightly faster (the Japan 'quake shortened the day by a millisecond or so, if I remember correctly). There are many theories as to what drives plate tectonics, and it's likely due to several things at once, like convection currents in the mantle, sinking ocean crust as it gets older, the strain from the bulge of our rotating Earth, etc. Given enough time, the Earth's core and mantle will eventually cool off, but the sun will have gone red giant by that time and made it all rather irrelevant.
I thought studying geophysics was something exotic as no one of my friends seem to relate to this. But once you look for that stuff you see it popping up everywhere. Cool video, very simple and visual explanation of complicated science !
What you said about the end of the solar system reminds me of a story about a scientist talking about the same topic. When he said that the sun was going would expand and destroy the Earth in about 4.5 billion years, a woman gasped. He reassured her that there was no need to be alarmed. 4.5 billion years is a long time from now. The woman said, "oh I thought you said 4.5 million years."
That density stuff really only works for fluids. I can leave a gold bar on a wooden plank (if I were a pirate for example) even though gold is much denser than wood, because both are solids. Given that the early earth was largely molten, this isn't a problem, but it's probably worth mentioning to avoid confusion.
That's exactly right. Compared to iron and nickel, it's still a small percentage of the core's composition, but there's thought to be enough gold down there to coat the Earth half a meter deep. Most of the gold that was or is in the crust (which isn't much, only enough to make a ~70 foot cube in total) probably came from meteorite impacts after Earth had differentiated.
That sounds easy enough; stack 16 million pennies. That's only about 15 mi above the ground...no problem, a simple tower of pennies up into the STRATOSPHERE! Now how long will this project take???
1:47 "Iron is the most stable element produced" no mater where you produce it en.wikipedia.org/wiki/Nuclear_binding_energy so there is no need for the clause "outside of a supernova" Though you do need a nova of some sort to get it back out where you can make planets out of it.
Martin Hoecker-Martinez Just trying to differentiate the creation of heavier supernova-borne elements like gold from iron, which can be made in more diverse types of stars
