How was Earth basically molten for hundreds of millions of years after its creation? Does shit need that long to cool off?

[Anonymous No.12122615]

>>12122609
yeah

Basically, yeah.

[Anonymous No.12122622]

>>12122609
It still hasn't completely cooled.

[Anonymous No.12122639]

>>12122609
it was pretty hot
then it cooled down a little bit but got smacked in half again and then it was pretty hot again

You're talking about underneath the crust, right?

Brainlet question but how easily could it even lose heat in the vacuum of space?

radiation

>>12122812
That and it's a fuckton of thermal mass with minimum possible surface area.

[Anonymous No.12122830]

>>12122815
I thought thermal radiation required a medium? Or is that convection, and radiation by definition requires no medium

[Anonymous No.12122832]

>>12122830
radiation doesn't require any medium, it's just losing energy by glowing into space
conduction and convection are a lot faster but they need a medium to work in

The sun is still molten to this day.

[Anonymous No.12122839]

I kind of ask myself the question?
How does an object gain mass in space... if matter is neither created nor destroyed. So an asteroid got locked in the orbit of the sun... and for it to gain mass. Asteroids must clash against the object in orbit. Or small meteorites. And if gravity results in the matter to be in constant motion the friction causes the molten state. But as more and more matter is added. A crust is formed above the core. And then "astroids/meteorites" containing h2o will slowly add water. Above this crust. So this process is so mind numbingly slow... it takes billions of years...

What if I crashed a sun of ice of equal size into it?

With size volume (retained heat) goes sup by the cube law while surface (cooling means) increases by the square law. Planet size masses need a lot of time.

On Iceland there are parts where you cannot grow potatoes as they would be baked in the soil.

[Anonymous No.12124915]

>>12124829
It doesn't.

If the sun emitted heat, space would be warm.

Space, of course, is cold. qed.

[Anonymous No.12125130]

>>12122609
I mean were would the heat go? It's literally a ball of rock floating in a void, the only way it can cool of is by radiating the heat away.

[Anonymous No.12125160]

>>12124915
Then how does my house stay cold when my neighbor is using his heater?

God you people are fucking stupid.

[Anonymous No.12125168]

high thermal mass, higher proportion of radioactive material in the core keeping it hot back then, and as everyone is saying radiative heat transfer is extremely slow

[Anonymous No.12125250]

>>12122830
Radiation requires no medium. It’s an electromagnetic wave. It’s relatively slow compared to conductive and convective heat transfer.

[Anonymous No.12125423]

>>12124915
Radiation need to hit something to warm it.
In the void there is... nothing, therefore no warming.
Actually there is not even a temperature in the absence of matter because temperature itself is molecular agitation.
Still if you were naked in space exposed to the sun, radiation would cook your exposed face pretty quickly because there isn't an atmosphere to absorb most of radiation

That sounds like it would save a lot of time. Just pick a few right before dinner is done.

[Anonymous No.12125439]

>>12122609
Because the early history of the solar system was primarily characterized by minor planetoids smacking into everything, constantly. That's where the planet got most of its water and metal deposits in the crust.

I hated how much salt they put into uncrustables. It was fucked up

He's stealing your heat bro

[Anonymous No.12126044]

>>12122609
Where does the excess heat go? Considering that there is nothing in space to transfer said heat? Radiation?
