No, there isn't anything that you add to glue so you can see it with a black light. A black light can be used to detect counterfeit currency in the United States.
Directly observing a black hole with a telescope is not possible because they do not emit light. However, we can indirectly detect them by observing their effects on nearby objects, such as the distortion of light or the movement of stars around them.
Space appears pitch black because there is no atmosphere to scatter light or create reflections. Without any nearby source of light, such as a star or planet, there is very little light present to illuminate space. Additionally, the vast distances between celestial bodies mean that any light emitted is often too faint to be visible from Earth.
No; your pupil is the hole in your eye that lets in the light. Without your eyes being able to receive light, you wouldn't be able to see.
No, a black hole absorbs all light that enters it, making it appear completely black. So if your body were a black hole, you wouldn't be invisible but people wouldn't be able to see you due to the lack of reflected light.
They are only noticeable under black lights, unless you are looking for it and look really closely, then you can see light ink. The tattoo only last for about 6 months.
Well, whatever we see, we see only because light reflects off it, and that reflected light is captured by our retina. Without a light source, there will be no light to reflect off the object. So, we can't see anything. Think of it like closing your eyes, or a pitch black room.
although tattoos are easier to see on caucasians, they are still clearly visible on African Americans as well! they will look fine no matter what your color, as far as i know,.
Black is not light. Black is the lack of light.
no you dont see them get the tattoos :)
You can't see infrared light without a special camera.
If the hair is really dark, and if you see just black in the light, then its black. but if you see brown in the light, it most likely is brown.
no because you need light to see
No, without light it's dark.

Technically, you can't "see" a black hole, since no light can escape from it, therefore the light cannot reach your eyes.
We see things as black when there is no light coming from that direction. Space is mostly empty, and neither generates light or reflects it, so it looks black. We only SEE things that reflect light, or that generate their own light.
