It may not be racist per se.

But it is sadly inaccurate.

Black holes arent actually black.

No light from any "black hole" has ever bounced back for any human being, colorimeter or measuring equipment to capture with their optical sensors. Hence we still cannot determine their actual color or appearance, or even if they are all similar in color and appearance.

He is being serious. You are displaying impressive ignorance and stupidity.

Black is the colour of things that absorb all light in the visible spectrum. It is an absence of light.

If you look at a black hole, all you see is darkness.
Darkness is black.
Ergo, black holes are black.

If anything, I would expect the center of a black hole to be either:

1) Really shiny - from all that pressure compressing all the particles within.

or

2) Be bright and luminous - like a ball of plasma.

or

3) Blindingly white - like the sun, but magnified many fold in intensity

Black happens when light is absorbed. See: dark, lacking in light, non reflecting, whatever. It's all the same shit.

That is bloody stupid.

If you put a red box in a dark room with no light- does it make the red box black?

You dont know of the nature of what lies at the centre of a black hole simply because we cannot observe it.

It may have the physical properties required to distort light into a visible spectrum, but we dont know because we do not have the tools required to observe it properly.

If a red box is in a black room, then yes, it's black, because it's not reflecting light.

Likewise, if the light bouncing off it itself has different properties, the box won't even be 'red' to begin with.

>their actual color

The "actual color" of something is what wavelengths reflect off of it. Nothing reflects off a black hole. It's actual color is black. In fact it's the blackest thing that could possibly exist.

Jesus Christ

You dont know if it cannot reflect light.

You dont know if it is black.

From where we are in the universe, they appear not to reflect light.

A if you put a cat in a box it will appear not to reflect light because of the box in the way.

If you put a cat at the centre of a black hole it will appear not to reflect light. It does not make the cat lose its physical properties.

Color may not be a physical property, but the way in which an electronic field distorts the visible light spectrum is a constant for identical electronic fields, and is a physical property.

Adding on to clarify:

Even if you put a cat at the centre of a black hole, (assuming the cat is invulnerable) the cat will not lose its physical properties that determine the way in which it distorts or reflects the visible light spectrum.

Hence, if we were to take it out of the black hole, it would still "have its color".

If you could take the centre of a black hole out of the gravitational well of the black hole, you will PROBABLY not find a black substance.

It will be a gooey plasma like state of all the particles it has condensed into its centre.

NO! That would be saying that so far as we know, Schrodinger's cat is black.

For all we know, yes, Schroedinger's cat is black. The whole point of Schroedinger's cat is that we don't know what it is.

>It is called "black" because it absorbs all the light that hits the horizon, reflecting nothing, just like a perfect black body in thermodynamics
>black is in quotation marks

Even physicists can't decide.

[Anonymous No.3647651]

sure is stupid in here
putting a cat of any color in a box and calling it black doesn't add to the argument because you take something 'the box' that is not an intrinsic part of 'the cat'
however a blackhole is defined as a point mass so dense it's gravity holds even light, so per definition (at least in our current def of physics) light will never reflect of of a black hole whatever you do
as proposed taking the centre out of the black hole to see its color equal trying to draw a round square
as proposed we need better instruments, once again no: light cannot escape the blackhole
one could propose some exotic method of measurement using entangle pair particels, but what you get then is a false color image which could indentify regions of different makeup inside the blackhole, but once again this doesn't correlate with any intrinsic color to the black hole

tl;dr: black holes are black stupid

You don't know that.


A red box in an unlit room is still red concerning the reflection it would give when white light is focused on it. You can't call it "black" because there's no light for you to measure. One of the physical properties of the box is to reflect all of the red light.

I think you agree with me on that ^ one. That's what you were saying. Now:

In contrast, the physical property of black holes is to absorb all light. If it absorbs all light, it doesn't reflect anything. That's black.

What you are saying is that we don't know the color of the mass inside the black hole. That's a different question.

By definiton:

>A black hole is a region of spacetime from which nothing, not even light, can escape.

The black hole is defined as a region, not an amount of mass (although this is used to classify it). As a region, it does absorb all light, so it's black.

As for the mass it contains, yes, we don't know. We don't know the properties it has so, if we the black hole as a region ceased to exist, and we had all that mass the instant after, we don't know what color it's supposed to reflect, if any at all.

So there we have it. That's all that people have been arguing here.

But guess what, it appears that black holes (as a region) are not black either. They do not emit anything in the visible spectrum, but it seems they do emit Hawking radiation. Check http://en.wikipedia.org/wiki/Hawking_radiation for references.


Conclusion: A black hole is a region in spacetime that is not black when the entire electromagnetic spectrum is considered, because of evidence that suggests the existence of Hawking radiation, but you can call it black (as in a color our brain interprets), because it does not emit light in the visible spectrum.

So as /sci/entists, we should consider that it's not black.
