Definitely. 20 years ago when homes were not littered with LEDs all over, I would wake in the night to total blackness.
I could still find my way around the house just able to see based on what is I suppose a noise floor of ambient temperature.
Go into the kitchen & behold the stove top emitting 'bright' white light, from I suppose a temperature of around 30degC /90F.
Obviously everything is a blackbody, but those photons surely can't be 'single' visible ones.
- yetanotherloser 4y agoGosh. I used to have pretty good night vision and recognise what you mean about "see based on the noise floor" - but I never had an experience like seeing the stovetop heat. Remarkable. I wonder how much variation there is between people? Unfortunately mine's faded with age so I don't think it's worth my trying to see if I can see that myself now...
- Luc 4y agoDid you consider you were seeing (very low amounts of) visible light? Temperature had nothing to do with it.
