Question 1

What is the color black?

Accepted Answer

Black is the color of a dark, deep night. It is the color of sorrow and death. Black is a combination of all colors, but it can't be seen because it absorbs light.

Black is the color of a dark, deep night. It is the color of sorrow and death. Black symbolizes grief in many cultures, such as Western cultures and some Asian cultures. In Western culture, black has long been associated with death and mourning. The Christian tradition uses black to signify seriousness or somberness; for example, priests wear black robes at funerals and people are often buried in black clothes to show their sadness at someone's passing. 
Black can also represent darkness or evil when used as an absence of light or hope; for example, people might say that someone who wears all black clothing seems sad or depressed because they are wearing "the color of despair."
The meaning behind the color black changes depending on where you live in the world and what culture you belong to; however, one thing remains constant: it symbolizes something negative like darkness or death no matter where you go in this world.

Question 2

What color is a Black hole?

Accepted Answer

A black hole is a region of space-time from which nothing, not even light, can escape. The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. Around a black hole there is an invisible surface called an event horizon that marks the point of no return.

A black hole has two main parts: the singularity and the event horizon. The singularity is where all the mass of the object has been compressed into and crushed down to a single point in space-time, creating infinite density and zero volume. It is said that once something enters this region it cannot escape its gravitational pull because it would have to travel faster than light to do so. This point is also known as "the big bang" or "the beginning." 
The event horizon surrounds the singularity at any given radius and this radius varies depending on how much mass has been squeezed into one area; if more matter gets added then the radius expands accordingly. Once you cross over this boundary you are pulled in by gravity but never come back out again because you would have to travel faster than light to do so; hence why it's called an event horizon (you can't see what's happening on the other side).

A Black Hole has two main parts: The Singularity and The Event Horizon. A Black Hole starts with having infinite density and zero volume, creating The Singularity Point where all of its mass has been compressed into one area, crushing everything down to just one point in space-time. Once something enters this region it cannot escape its gravitational pull because it would have to travel faster than light to do so, which isn't possible since nothing can go faster than light (hence why they call it an Event Horizon). This means that once you cross over this boundary you are pulled in by gravity but never come back out again because you would have to travel faster than light to do so; hence why they call it an Event Horizon (you can't see what's happening on the other side).

Question 3

Why does Black Friday happen on the day after Thanksgiving in the United States?

Accepted Answer

Black Friday is the day after Thanksgiving in the United States. The date was selected because it follows a tradition of stores opening on the Friday after Thanksgiving, which is typically one of the busiest shopping days of the year. It also coincides with some retailers' end-of-year sales and provides an opportunity for consumers to take advantage of post-Thanksgiving discounts.

The day after Thanksgiving has been recognized as Black Friday since at least 1961, when it was mentioned in a Philadelphia newspaper article. The day is popular with shoppers because it marks the beginning of America's Christmas shopping season and many major retailers offer special deals that are only available on this day.
