Yes. All objects can be seen in the dark in any spectrum except the visible. That's how night vision (heat vision) works.

Oh, forgot to mention.
If you mean only without the presence of outside light, then you could include fluorescent and phosphorescent objects, which create their own light, and would therefore be visible in visible spectrum (as well as all other spectra too)

>>3601515
Without the presence of light. Including IR?

Do you mean without any radiation (light) being emitted or reflected by said object?

I'd say probably not, unless you count gravity and shit.

Yes. Sonar and echolocation.

Yeah I was thinking to add with the "without use of tools" but I wanted to see what I would get first as answers.

No see what I want to know is, is there a way to see an object in the dark but still seeing its natural forum not its heat or anything. Seeing it as how we see it in light. Yes tools can be used but they can shine light at the object or at "you".

Well, all bodies emit their own infrared light. That's called heat. In fact, all bodies emit light in every wavelength with varying intensity.
That's what you are seeing with heat vision; the infrared part of that body's emission spectrum.

what is sight? its particles of light hitting your retina, without light, theres nothing to hit it and therefore you cant see anything.

(is it retina? im not exactly sure lulz)

full retard much? anyways, blind people can make out objects just with their sense of touch, if thats what youre after.

>>3601546

So with that said is there a way to let say use tools to look into the past of the faded light of let's say hitler and see his "ghost" heat wave image of the past?

>>3601562
No because
1) We can't look into the past, unless the object is very (on the order of light-years) far away, and
2) what the fuck is "faded light"?

ITT: full retard

>>3601591
Agreed...

Depends on what you mean by dark. With out visible light, yes you can see it easily using other spectrums.

Without any electromagnetic radiation. No you couldn't "see" it, but you could use other methods to gain an understanding of its shape which can be displayed in a visual means ( sonar, ect. ).

Without any form of energy transfer you will see nothing.
