No because that’s essentially an observer-less observation and quantum physicists would love to get a hold of that in order to look without looking, but there is no such thing.
There are no silly questions concerning objectivity since it’s very difficult to get one’s head around.
You may ask other people for an objective view of a personal situation you may have and it will be more objective than your own assessment, but it’s still subject to the limitation of the other person’s ability to relate to you and your problem (among other things). The degree of objectivity is subject to the subject’s tools of perception and internal biases.
A subject can only observe with the tools it has to observe (be affected by something). A photon, for instance, can only observe that which contains charge because that is the only means of affecting electromagnetic radiation. Dark matter has no effect on photons since dark matter contains no charge. However, dark matter does affect space which affects the path of light, but it doesn’t affect the light directly.
Dark matter is only real to us in terms of gravity and, although we can learn more about dark matter by studying the interactions it may have on other elements, there is no way for us to objectively observe the dark matter because we do not possess the tools necessary to “see” it.
I suppose we can extrapolate and surmise what something may look like if we weren’t there to look, but it’s not real observation.
Goethe said, and I agree, that thinking (deduction) is a tool of perception just like vision, smell, etc, so we may be able to piece together objective views by “virtual observation” (for instance, what the universe looked like at the moment of the big bang when viewed from outside the universe, whatever that means), but we can never be assured that we’ve considered all the information (in other words, we can’t know what we don’t know.)
You can differentiate subjectivity into types if you want, but I was just saying there was no need to in this case.
Light is just a higher-frequency radio wave or a lower-frequency xray and visible light is a sliver of the radiation that exists.
What you commonly call “heat” is really infrared radiation. What physicists call “heat” is all EM radiation since heat is energy in transport.
Birds can see tetrachromatically via a 4th cone that allows perception of ultraviolet radiation and, presumably, they have a neural network that allows conceptualization of a color such as ultra-orange, which does not exist to us. People wearing sunblock at the beach probably appear like they’re wearing aluminum foil to birds due to the intense reflection of UV light.
Deer hunters should also be aware that deer can see UV light (blue and up) very well and although some pee dribble may not seem very real to us, it’s like a light bulb to the deer. Deer are crepuscular, meaning they’re most active at dawn and dusk in order to take advantage of the remaining UV light from the sun to pinpoint predator urine while also having the ambiance dark enough for predators to be at a relative disadvantage.
I like that show
