    Blackholes
In summary, the conversation discusses the appearance of a black hole from behind and whether or not it is observable. It is compared to a heavy object on a sheet and the possibility of seeing an event horizon on the back side. The participants share their thoughts and one provides a link for further information.

Hi guys, can't find a post similar to this so ill ask;

What does a black hole look like from behind? The spatial apperance is similar to a heavy object sitting on a taught towel or sheet (due to its large mass affecting space-time), but what does an observer on the singularity side (further from the event horizon) see? Does it appear to have an event horizon (black cirlce surrounded by blurred matter circles) on the back side, does it appear as a dot (viewing the singularity from behind) or is it not observable? Surely all 3 dimensional objects have a back and front to go with their other 2 dimension hence making it observable?

Thoughts?

Thanks!

I know there is an example somewhere of what it looks like to fall into a black hole. I just don't remember where. Perhaps someone knows the link.
 

1. What causes the appearance of black holes?

The appearance of black holes is caused by the extreme gravitational pull of the collapsed star at its center. This pull is so strong that it traps even light, making the black hole appear completely black.

2. Why do black holes have a swirling appearance?

The swirling appearance of black holes is due to the rotation of the matter that is being pulled into it. As the matter gets closer to the black hole, it starts to swirl around the event horizon before eventually disappearing into the singularity at the center.

3. Do all black holes look the same?

No, black holes can have different appearances depending on their size and surroundings. Smaller black holes may have a simpler appearance, while larger black holes can have more complex structures such as accretion disks and jets of matter shooting out from the poles.

4. Can we see the actual appearance of black holes?

Currently, we cannot see the actual appearance of black holes as they do not emit any light and are completely black. However, we can observe the effects of their presence on surrounding matter and use simulations to visualize their appearance.

5. How does the appearance of a black hole change over time?

The appearance of a black hole can change over time as it continues to accrete matter and grow in size. As more matter is pulled in, the accretion disk surrounding the black hole can become brighter and more active, causing changes in its appearance. Additionally, the gravitational pull of the black hole can also distort the appearance of nearby objects, such as stars and gas clouds.
