Black hole

Black hole

a black hole seems "black" because all light gets absorbed into it and none reflects to our eyes so we just see a black spot in space
if a black hole were to somehow (i know its not possible) stop absorbing light and let it reflect back to our eyes while keeping its normal compositions what would we actually see? a star? a large pile of mass?
God? Wolverine?

Gay men having sex...According to scientists who study these things.

Thankfully it'll never happen though.

depending on the wavelength of light, we would see an infinitely small point of light, likely with extremely high brightness [ya?], in the colour of said wavelength.

if it just stoped absorbing "light" altogether, the colour would be white.

so we would see a white gap in space?

Seems like a nonsensical question to me. If a black holes start reflecting stuff its no longer a black hole.

What would a dog look like if it ceased to be a dog?

However if you want to side step the set up and get to the very simple question of "what is the shape of a black hole?" the answer is "a perfect sphere". In fact a very small one: the Earth would be 1.2 centimeters across, our whole solar system, would be six kilometers across, the Milky Way would be 2 light year across (less than the distance between here and the nearest star).

If you strip away the event horizon... well you no longer have a black hole anymore.

inimalist answered it pretty nice

It seems more like he's describing the singularity to you.

however, Sym understands this stuff much better than I

I was just talking about light perception

First of all black holes are theoretical, not prover to exist. Even though you will hear a lot of "black hole in the center of our galaxy" or "...wierd anomoly is probably a black hole" on the news and in science magazines.

If such a high mass object exists, it isn´t a "hole" as such. You can´t have a hole in nothing. But because the gravity is so strong nothing escapes to be measured so it appears as a hole to an observer.

they were able to photograph the event horizon of the Milky Way a few years ago.

Wow sounds amazing, where´s the picture I can´t find it anywhere?🙂

Here´s an article which might be what your refering to..

or this picture taken by the NASA's Spitzer Space Telescope

Black holes are theoretical in the same way mice are theoretical. In that we know there are things that accomplish tasks physicits predict that only mice can do and stay for centuries in places where you turn into a mouse if you don't leave really quickly.

Okay, bad choice of metaphor.

While you're right that it isn't a hole (in fact physicists are certain they're black either), it wouldn't be a "hole in nothing" it would be a hole in space-time.

It has to do with this: http://www.cfa.harvard.edu/news/2008/pr200816.html

because I remember that was the telescope technique they were using.

I can't find it for the life of me... strange...

Wolverine, scientists already proved it if they would be visible they would look exactly like Wolverine. This or pink shoe creme.

I want to see God but I have a feeling Wolverine is what I will see.

IMO we would see is a very large mass of anti matter, or just a complete void of unspace

or maybe its just alien planets in cloak

whats wrong with you colossus?

Antimatter looks just like matter. If you could look inside a black-hole you would see a singularity. What a singularity looks like is unknown, but it might look like the big bang.

In a manner of speaking: the implicate order gives rise to the explicate via superstrings. The explicate order is returned to the implicate via black holes.

what does the big bang look like?
