This came out last year: https://phys.org/news/2019-01-rotatin​g​-black-holes-gentle-portals.html. We've known forever that you a rapidly rotating black hole has a different sort of singularity. But it's always been a problem of (a) finding one to test, and (b) rings... very dangerous... you go first.

Yo momma so fat, she creates her own, noticable, gravitational lensing...

I'll go first if you provide me with an FTL ship. (Terms subject to change after delivery of ship)

This is a variation on the Kip Thorne thing, right?  The infinitely long cylinder that spins very quickly?

I have questions:

Can you beam a message thru?

What about causality?

Can I get fries with that?

There's that, but I think he's talking about the ring-shaped singularity of rotating black holes being a portal to... elsewhere.

That idea is like 4 decades old... at least, not sure how well it's aged.

And you still have to deal with the event horizon and the tidal forces first.

According to recent PBS Spacetime episodes, there's an analogous effect in charged black holes.

Great. How do we get to the black hole?

If Planet 9 really is a small black hole, then it's possible that Mass Effect was correct in saying that a device for interstellar travel was beyond the orbit of Pluto.

KarmicDisaster: Great. How do we get to the black hole?


According to the article it's only 30,000 light years away. Easy!

Fine. I'll drive if you pay for gas

We should test this. I'm pretty sure I've got a supermassive black hole kicking around the house somewhere here, unless the dog buried it in the backyard again.

If you jack the math off long enough, you can conjecture anything.  Don't mean much.

Wake me when they actually have a working prototype scaled down to a stepper box size or something.

Ignoring the fact that the radiation around a black hole is so intense, you would pretty much be vaporized before you got within like 5 AU.

More like universe travel. If you feel like arriving in the other universe as dark energy.

Good luck.

The event horizon isn't a real thing. Tidal forces are a biatch though.

So I just finished Stargate Atlantis. Is SGU worth watching? I've heard mixed reviews.
