And parking below the event horizon of a black hole could be done. So what if light can't escape from it, if your ship can fly faster than light.
According to this physicist, sure:Also a lot of Voyager's "Timeless" in this one. And parking below the event horizon of a black hole could be done. So what if light can't escape from it, if your ship can fly faster than light.

That is a very good question.
To answer, it we need to remember that for a large black hole the horizon has no unique local property (the event horizon is a global property that cannot be “seen” locally).
For a particle near the edge of the horizon (doesn’t matter which side) spacetime looks quite normal, with a large enough black hole, the gravity can be weak as necessary to be ignored. So going outside the horizon isn’t a case of a large barrier at all.
So what happens at the horizon ? The particle light cone is directed toward the singularity, hence going outside the horizon means the particle needs to travel back in time, or move on a space-like curve.
So we can re-ask the question as
To answer the question we need to look at relativistic QM (non-relativistic QM has no light-cone constraints). Here we can use relativistic propagators (Propagator - Wikipedia) to see that there is no support for the wave function outside the light-cone. Ie, a particle cannot tunnel in a non-causal way.
- “Can a particle tunnel in a way that breaks causality ?”
Conclusion: A particle cannot tunnel itself outside the black hole horizon.
Comment for the experts: I am ignoring issues related to complementarity, firewall etc. In the above the horizon is exactly the classical general relativity picture with no additional quantum properties.

Last week, they couldn't even get the videos to load on the site for hours. I ended up just waiting the next day as I have Hulu. That said, tonight I got to the last few minutes when a timer popped up saying it was jumping to some other FOX show I didn't care about in 10 seconds. There was no way to stop it, no way to cancel any countdown, and so at 0 it jumped to whatever the hell was trying to load. I went back, and the Orville episode started over. There is no progress bar at the bottom for some dumbass reason. FOX's webmasters don't seem to be very good at their job.I'm going to avoid the spoilers, and just vent here.
I missed starting the show at 9:00, so I started watching at 10 on Fox's website. For some reason, the little progress bar which allows you to jump back and forth though the episode isn't there.
I got around 2/3rds through the episode (right to where they talk about going to the bottom of the Pacific Ocean) and I got stuck on an endless commercial break with no commercial. After a few minutes of this, I paused and unpaused in an effort to stop the freeze. The entire episode restarted from the beginning and I'm unable to jump ahead. Meaning I have to let the episode now replay in the background for nearly 30 minutes - or just give up on watching it until they actually allow me to jump around.
That's really all that matters. I've seen dumber stuff in trek and still managed to be a fan.I thoroughly enjoyed the dumb thing. Because Ed and Kelly and Claire and Alara and Everybody.

We had Hulu TV for a while, but our local cable provider came up with a better offer (in terms of live TV) and so my family went for it. I mean, waiting a day isn't a sacrifice or anything, but it's super frustrating when you're only looking to see the last, say, 5 minutes of an episode that was cut off.I have Hulu TV. I used the DVR feature to record it because I knew I wouldn't get home in time. I ended up seeing it at ten.
Oh yeah, been there. And the DVR isn't perfect either. I still got to see the end, but the recording skipped a couple of minutes during the climax.We had Hulu TV for a while, but our local cable provider came up with a better offer (in terms of live TV) and so my family went for it.
