how do people detect this cold light

Temperatures of surfaces under an unobstructed night sky will lose more of their heat than surfaces with obstructions, roofs, trees or clouds over them, and this happens even on nights when the Moon isn't present

with a laser detector right?

@Fran not sure exactly
Colder then objects or ground that is in the shade

I have not been able to confirm moonlight is cool. Perhaps it is but I have not had success testing it.

if it was in the outside, it would be colder at night cos the inside would have insulation

@Happygrandad Yes
But not a detector
A laser thermometer

yeah

Not that I spent a lot of time testing it.

alright you guys just flew over my explanation on why it's colder

laser thermometers measure the air temperature, not what it directly points at

like you guys are saying putting a piece of paper 10 or 20 feet above a thermometer will change its temperature because of insulation @mineyful

It proves cold light
Anyone can prove it themselves

On my walks it was colder in moon light. But there were lots of trees which could have caused that as well.

The moonlight does not cause an object to get colder. It’s the object in the shade that gets warmer.

When an object (or surface) is covered or shaded with a hand, roof, tree or cloud, it radiates less of its heat into the night air, and it will become slightly warmer than an object (or surface) that is exposed to the open night sky.

yes so the measurement doesn't have to be done in different buildings

light contains energy, if it were cold it would have negative energy

which is impossible

yeah I don't think negative energy exists lmao

unless ur saying that the light is just colder than the surroundings

no, that's llike saying everything cold has negative energy @Happygrandad

Heat, energy that is transferred from one body to another as the result of a difference in temperature.

lol thats why i said the above

yes, light just has to draw energy from what it hits

Anything that is covered by moonlight is colder than anything that is in the shade and not in the moonlight

yes

moonlight is just light

You may well be right. Like I said this would be no easy test. However if I use a magnifying lens with sunlight I can melt steel if it is large enough. Not with moonlight. It produces no heat at all.

lmao california I have you an explanation and you aren't alking about it

Heat, energy that is transferred from one body to another as the result of a difference in temperature.

Again it has been proven and can be proven by anyone with a Laser Thermometer

light only transfers energy

some people think using a magnifying glass would amplify the cooling effect

Heat is the energy an object has because of the movement of its atoms and molecules which are continuously jiggling and moving around, hitting each other and other objects. When we add energy to an object, its atoms and molecules move faster increasing its energy of motion or heat.

...

But surely if moonlight was redirected sunlight it'd be warmer than cooler?

magnifying it would only magnify the beam

making it hotter surely

moon isn't that reflective hence the drop in temperature given off

I tried one of them. It did not seem to work well. Even then is the warmth just going into the sky more where the moonlight can hit.

The answer is that the Moon is actually not very reflective,the Sun is just very bright. The Moon reflects only about 11% of the sunlight that hits it. But the Sun is so bright that even this much reflection looks very bright to us.
