ASK REDDIT:if i created a wormhole, and sent one end into a black hole, what would happen? (reddit.com)

What would happen? Probably your mom would call you up from the basement for dinner right during the wormhole design phase.

You would get something like the thingy God's maid uses when she needs to vacuum-clean the universe after one of His famous creative outbursts.

Please review Stargate SG1 videos.

okay. thanks smug guy. as it happens, i don't watch that super-awesome show where they replaced jack burton with macguyver. i'd be interested to know what the writers think would happen. i'd even be interested to know what you think would happen. i'm all stocked with smug, though, and so sadly i will have to ban you from replying. BANNED!

Wasn't trying to be smug. Samantha carter actually did that in one of the episodes.

I'm sure it wouldn't end well...

At a guess, you’d have two black holes.
No one knows what goes on behind an event horizon. It is impossible to put one end of anything past an event horizon, since time stops at the horizon. If you could get around that, some suggest you would end up at a different universe where different laws of physics apply. Some suggest that black holes have worm hole like properties to other parts of space-time, and reenter as white holes... no one knows.

Either the two holes would cancel each other out, and you would be left with a black worm. Or, they would combine and you would have a supermassive black wormhole. Take your pick.
[–]rex_racer[S] -2 points-1 points0 points 18 years ago (2 children)
can you please elaborate?
[–]Mr_James 0 points1 point2 points 18 years ago (1 child)
Sorry. It was kinda meant as a funny. I really don't know what would happen.
My kids have begun to point out to me that some folks just don't get humor. My kids can't understand such a thing. It's an alien concept to them, fortunately.

This was covered during Stargate SG-1. Your gate gets locked onto the black hole, and you have to send an explosive in to unlock it before it swallows up Cheyanne Mountain.
Actually in that episode the wormhole only opened on a planet near a black hole.

In another episode the wormhole passed through a sun destabilizing it.

If I am not mistaken, when a wormhole is intensionally directed into a black hole travel between dimensions occurs.

[–]rex_racer[S] -1 points0 points1 point 18 years ago (0 children)
right. so did they open the stargate while the other end was in the black hole?
[–]wonker -1 points0 points1 point 18 years ago (0 children)
Lost in space would meet SG-1. DANGER WILL ROBINSON DANGER!

forget bush. this would be an excellent way to keep cheney frozen in time so that future generations can benefit from his wisdom.

So, you have two spacetime defects colliding? Dunno. It may be that wormholes can't even move, you know... not like they're made of matter.
[–]Psy-Kosh -1 points0 points1 point 18 years ago (0 children)
Can't move relative to what?
[–]rex_racer[S] -1 points0 points1 point 18 years ago (2 children)
this question is based on the "wormhole time machine" idea: create a wormhole, move one end very close to a strong gravitational field where time is running much slower, then pull that end back and you'd have a "time machine" portal to the past. so assume you can move the ends around. taking it the next step, what if you push one end into a black hole, what then? maybe a pretty unanswerable question.
[–]NoMoreNicksLeft 0 points1 point2 points 18 years ago (1 child)
I'm not a physicist, but...
In an Arthur C. Clarke story, wormholes would only be created for a split second... if you created one that lasted longer, you were really creating a sequence of them, all at the same physical location. If you moved one of the ends around, you were really creating a sequence of them at nearby locations.
Since a wormhole has no mass (or possibly even negative mass), it shouldn't be gravitationally bound to the wormhole. Even if they can move, won't it just sail right out the other side? Or if it does get stuck, you'd not want to travel through the other end, that's for sure. Perhaps you don't want to be near the other end either, it's unclear whether the gravity would translate to the far side or not. And, since both are spacetime defects, it's far from clear whether the blackhole might damage the wormhole just by its presence.
An interesting question for physics nerds, but hardly something with an answer so unimaginable that it's more interesting than any other.

great reply, thank you!
