[QUOTE=Cone;37469166]it wouldn't "cease to exist", our gravity would just get totally fucked up as it passed through. even if it did hit Earth directly and the whole planet got destroyed, matter is indestructible; we'd become a ring of rocks around it, then those rocks would quickly get sucked in and become invisible and intangible as the light around the hole is warped.
it is physically impossible for something to just not exist anymore, or at least black holes don't do that.[/QUOTE]
Did you know that a black hole as massive as the Earth would only have a diameter of nine millimeters? A black hole the size of a Pea orbiting the sun...
[QUOTE=Mingebox;37469027]It wouldn't really be any different to a rogue star passing through, it the gravitational effects on our orbit are probably what we would have to worry about.[/QUOTE]
The scary thing is that while you can see a star passing through in advance, you can't see a black hole at all. Black holes are only "visible" by the effect they have on their surroundings. I'm pretty sure if a black hole isn't actively feeding, it's pretty much invisible.
The thought that one minute we could be here, and the next minute we could be gone without even having a warning is quite unnerving.

They convert it to pure energy IIRC
space why u so crazy
[QUOTE=NeonpieDFTBA;37470785]They convert it to pure energy IIRC[/QUOTE]
Not immediately, though. (Maybe.) It radiates it over a veeeery long period of time.
Wheres the scary rating?!?
Wow, seriously guys? It's Afro-American Hole.

The Haitian Holes don't like that term

well shit i was gonna post the song but like 3 people beat me to the joke
still cool though
[QUOTE=JohnnyMo1;37468955]That's not what it would be like at all.

That's more like a vacuum metastability event[/QUOTE]
what is a vacuum metastability event
[QUOTE=Pierrewithahat;37468315]Sagittarius A is the super massive black hole in our galaxy.
There's pretty much one at the centre of every galaxy and we're caught in it's gravity well and we're probably slowly getting sucked into it.

We'd still be fucked cause black holes just shred everything that goes into them.[/QUOTE]
True, but by the time earth would be sucked in, billions of years will pass, earth will be a dead heap of coldness, and our entire solar system would have likely experienced its ultimate fate like the big rip/crunch.

potentially the universe is only in a locally stable quantum vacuum state and at any moment some part of it could tunnel into a lower energy vacuum state and a bubble of universe-rewriting horribleness would expand outward at the speed of light until it rewrote the entire universe, changing physical constants and whatnot and making the existence of life impossible

Not entirely true, you'd see gravitational lensing around the black hole so you'd see the front and back of it.
Anyway, a black hole would be scary as shit because you'd be ripped in half as you died, the laws of physics pretty much break down at the singularity of a black hole. even if it was a wormhole we'd be dead because of the spaghettification effects on matter that the black hole has.

It might not even matter because there's recently been a debate going on in the physics community about whether "firewalls" exist i.e. thermal barriers that incinerate any observer as soon as it crosses the event horizon.

Imagine what that would look like
Reality being altered before your eyes

That would make sense, with all the heat most likely being generated as things are sucked into the black hole and rub up against each other, unless singularities work differently.

it wouldn't look like anything since it travels at the speed of light. One instant you're there and the next you're gone

You'd be ripped apart before your mind could register it.
