Not necessarily. Temperature determines which way heat energy flows, it says nothing about how fast it flows. I can hold my hand in an oven at 500 degrees with no problem because the transfer is very slow. Briefly touching a much cooler 150 degree piece of metal would give me a nasty burn, because of how quickly the heat transfers.
Not necessarily, maybe the thermal properties of the lightsaber are modified to give them high thermal resistance that is lowered contextually (like when youre slashing up some guy)
That's where _the force_ comes in. Nerd Shamed by vvv
Han Solo isn't a force user. Hoth
TBF He had heavy duty insulated gloves on and the lightsaber was only powered for ~10 seconds.
That is true. He could do it. But there is the problem of the Tauntan. If the saber did produce that temperature, they wouldn't need to rest inside of the the warm carcass, therefore, by the movie's logic, the saber doesn't produce much temperature.
Too much wind. Tauntaun was also only temporary as he set up a shelter.
If you had 5000° you could make a hot tub in the snow.
Plus it wasn't exactly hot on Hoth
To be fair, Hoth was pretty cold...
Don't think General Grievous is a force user either.
I don't count that as canon. Plus he had metal hands so...
Whether or not Han Solo unknowingly uses the force is an unanswered question.
