Interstellar anyone? :)

Based on initial findings, all the black holes discovered thus far have varying degrees of spin because when a star rapidly collapses, it will never be a uniform process, so spin will always be part of the equation. With this being said, yours truly has always thought about the possibility of black holes being worm holes (entanglement) and that travel through them, if they are big enough and the spin is fast enough, is a viable hypothesis based on conjectures put forth by people far more qualified than this rube in all matters regarding physics, black holes, worm holes and the possibility of interstellar travel. :)

Flying through a black hole

My team at the University of Massachusetts Dartmouth and a colleague at Georgia Gwinnett College have shown that all black holes are not created equal. If the black hole like Sagittarius A*, located at the center of our own galaxy, is large and rotating, then the outlook for a spacecraft changes dramatically. That's because the singularity that a spacecraft would have to contend with is very gentle and could allow for a very peaceful passage.

The reason that this is possible is that the relevant singularity inside a rotating black hole is technically "weak," and thus does not damage objects that interact with it. At first, this fact may seem counter intuitive. But one can think of it as analogous to the common experience of quickly passing one's finger through a candle's near 2,000-degree flame, without getting burned.

Interstellar comes to mind here without question as real science regarding black holes and the possibility of going through them is a prime reason why this film works IMHO.

No sound in space is another reason why this flick works. :)

Science never disappoints. :)

Addendum: Black holes do spin fast, really fast without question ...

 The crumbs left over from a supermassive black hole's recent meal have allowed scientists to calculate the monster's rotation rate, and the results are mind-boggling.

The huge black hole, known as ASASSN-14li, is spinning at least 50 percent the speed of light, research team members said. 

"This black hole’s event horizon is about 300 times bigger than the Earth," study co-author Ron Remillard, of the Massachusetts Institute of Technology (MIT), said in a statement. (The event horizon is the limit beyond which nothing, not even light, can escape a black hole's gravitational clutches.) [Images: Black Holes of the Universe]

"Yet the black hole is spinning so fast it completes one rotation in about two minutes, compared to the 24 hours it takes our planet to rotate," Remillard added.
