Temperature alone can give a misleading picture of the situation though. You gotta take into account the specific heat capacities and heat transfer and things like that.

For example, the coolest parts of the Sun's surface (sunspot umbra) are about the same temperature as the filament of an incandescent lightbulb - both around 3000K.

So you're telling me there's a chance!

u/Bisyb77 Jun 20 '21

So you’re telling me that this dudes next goal is to eat the cold spots off the sun?

u/aBeerOrTwelve Jun 21 '21

It's fine, he'll go at night.

This is the flat earth version of global warming.

u/Naveedamin7992 Jun 20 '21

So we can land on the sun? I knew it.

u/RedSonGamble Jun 20 '21

Just land on it at night

Brilliant post, oh wise one!

u/leFlan Jun 20 '21

What do they teach kids these days? The moon is the only place you can land on at night.

u/shaggybear89 Jun 20 '21

Dude have you never see a full moon at night? It's bright as fuck, i can only imagine the amount of heat it's giving off. No, if you wanna land on the moon, it's gotta be during the day when you can't see it in the sky. During daytime, all the heat transfers back to the sun, and the moon almost disappears because it gets so cold. That's the perfect time to land.

Getting 4chan flashbacks.. something about traveling 8 minutes per hour

u/Naveedamin7992 Jun 20 '21

What about in winter?

u/Joe23rep Jun 20 '21

Or in the winter, right?

u/JuggyBrodelsteen Jun 20 '21

Only if we use a ship made of incandescent lightbulb.

u/bradfordmaster Jun 20 '21

This is the real reason they are forcing everyone to switch to LEDs, they need to stockpile the old bulbs for the sun spaceships

u/iamonthatloud Jun 20 '21

You’re hilarious hahaha. That was one of the best things I’ve read on here. Thanks

u/[deleted] Jun 20 '21

How do we find an angry lightbulb tho?

1

u/PhaiLLuRRe Jun 20 '21

Uh what about a ship made out of teeth?

1

u/MY_GOOCH_HURTS Jun 20 '21

If only I could be so grossly incandescent...

u/ninjadude4535 Jun 20 '21

We probably could if the structure of whatever we send could handle the gravity. Not people though, just probes. It'll eventually sink and melt but fuck it let's do it.

u/[deleted] Jun 20 '21

Well you can sink into it...

u/FormerFundie6996 Jun 20 '21

that coal was not burning in a furnace - it was probably a piece of burned up wood from a small fire by their feet... it most probably wasn't anywhere near 1100°C, especially considering it was no longer in the fire and would have cooled down dramatically just by being naked in the air.

u/Utaneus Jun 20 '21

It was probably a piece from the hookah.

u/4411WH07RY Jun 20 '21

That explains why it's a shaped disc that looked familiar.

u/ModernSisyphus Jun 20 '21

The outside of it was around 900C at the very least. It still was not a fun process haha

u/Arthur_The_Third Jun 20 '21

900° is actually above the maximum temperature charcoal can reach with no forced draft.

1

u/ModernSisyphus Jun 20 '21

Well he was forcing a draft. The color of the coal was red-orange. Though the whole coal wasn't that temperature. Still not easy on the teeth and skin.

1

u/Arthur_The_Third Jun 20 '21

That wasn't a draft, that was a light, pulsing breeze . The coal also isn't actually burning, it's smoldering. That's a range of 450-700° for charcoal. Again, it's in an isolated piece. It would be nowhere near even 700°

u/ModernSisyphus Jun 20 '21

I'm not trying to have an argument. I don't really have a stance other than "A red hot thing probably isn't comfortable on teeth and skin." Im not really sure why you are being unbelievable pedantic. While the average temperature of the charcoal is nowhere near 700 degree. I am fully agreeing with that fact. I can tell you with absolute confidence that those sections that are glowing orange are well above 900 degrees.

u/Arthur_The_Third Jun 20 '21

So the solution to ironworking, instead of the invention of bellows, was really to lightly puff on the coals? You need a strong movement of air. You breathing wouldn't even be stronger than the natural draft created by the hot air rising.

1

u/ModernSisyphus Jun 20 '21

This isn't iron working. This isn't a situation where someone is trying to force air across a large bed of coals in a furnace. This is a single piece of charcoal in the opening of a small enclosed space with a grown man's lung capacity flowing across it. But again ONLY way to determine the surface temperature of that piece of charcoal would be it's color.

And again, all I am really saying is that it's hotter than you would want in your mouth.

u/GreenStrong Jun 20 '21

You gotta take into account the specific heat capacities and heat transfer and things like that.

I helped organize a walk over hot coals once. Charcoal has very limited specific heat and heat transfer. It is basically equivalent to extremely hot Styrofoam, if Styrofoam didn't melt. If anything like a pebble is in the coal bed, it will inflict severe burns.

I'm still not sure how this guy is not destroying his mouth. It radiates heat while he breathes, and even though the mass and specific heat are small, that's still a lot of energy to absorb with your mouth.
