$\begingroup$ Black = no light. A black hole is black because no light comes from it, i.e. it is invisible. $\endgroup$– hdhondtCommented May 24, 2017 at 23:30

3$\begingroup$ @hdhondt Those aren't the same thing. Invisible would be perfectly transparent. $\endgroup$– JMacCommented May 24, 2017 at 23:55

1$\begingroup$ What does unimaginably realistic mean? It obviously has been imagined. There are plenty of calculations of what black holes look like. If you think they are stereotypical, that's likely because they all use the same laws of physics. $\endgroup$– ProfRobCommented May 25, 2017 at 6:51

$\begingroup$ Black holes are invisible, but the shadow left behind by the event horizon (aka that dark sphere you see in every single black hole animation) is. $\endgroup$– AlastorCommented May 21 at 10:46

- Always respect the author’s intent
- Don’t use edits to reply to the author
How to Format
-
create code fences with backticks ` or tildes ~
```
like so
``` -
add language identifier to highlight code
```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- quote by placing > at start of line
- to make links (use https whenever possible)
<https://example.com>

<a href="https://example.com">example</a> - MathJax equations
$\sin^2 \theta$
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. quantum-mechanics), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
