Space is not cold.
Nah, space is cold, but it is also a extremely good insulator.
Because you’d need molecules to bounce off of things in order to transfer energy. No molecules means no heat transfer.
So a hot pan in space could stay hot for months.
I mean yeah the concept of temperature doesn’t really make sense when talking about empty space. That said irl space is anything but empty. There’s at least a perpetual quantum fizz of virtual particles popping in and out of existence. The average temperature of stuff in space is about 2.7K which is really freaking cold.
Space is not anything but empty, its not totally empty.
So the “stuff” might be at 2.7K but it won’t be able to absorb much energy from a hot object. Which is why cooling is an issue in space and not freezing.
Space itself is cold, but any surface subjected to radiation, e.g. sunlight, becomes hot.
