Comment on If the color of the Sun was orange, wouldn't the clouds and everything white also be orange? My friend is adamant that 30 years ago the "real" Sun was orange but got replaced with a white LED.

  I’m trying to get you to stop reducing temperature scale to “anything over 60 °C is hot” because it’s not useful: a clearer distinction should be made between something that regularly causes house fires and something I unscrew while it’s on to put under my blanket when my toes are cold. Human perception of temperature (classic 0-100 °F) just does not allow comparing things an order of magnitude higher (in Kelvin ofc). There’s also more to heat, its effects and how it’s perceived than a single measurement of temperature: thermal mass, conductivity, color (exchange via radiation differs between black and white bodies) etc.

  Also, it’s indeed ad hominem but you did choose the username yourself.

    Literally all I said is large LED arrays get hot. I did not say that there is nothing hotter in the world than LEDs. I didnt say LEDs were the only source of heat in the universe. I said nothing, but that LED arrays don’t run cold as the original commenter thought.

    You’re the one thats spent this entire time trying to “Well ackshually…” and wring your hands in desperate argument to prove a point that no one was making or even talking about.

    And you want to call me an idiot for it.

      You’re still being reductive. An indicator LED can work without any part of it more than 10 °C above ambient temperature. No incandescent light bulb can achieve this.

      And yes, there are indeed lighting systems that use many low-power LED chips spread over a large area, none of which get hot even by human standards. These cost a lot of money but last extremely long.

        I’m not being reductive.

        You’re just being an ass.

        This is the equivalent to someone asking what color is the sky. Someone saying its blue, then you coming in spending hours flailing your arms desperately screaming “THE SKY ISNT BLUE, IT ONLY APPEARS THAT WAY DUE TO THE COMPLEX NATURE OF THE INTERACTION OF SOLAR LIGHT ON THE MOLECULAR COMPOSITION OF THE UPPER ATMOSPHERE TO MAKE IT APPEAR BLUE”, Then getting big mad when someone goes “So its blue then, thanks”
