I just watched interstellar again, and I just love that movie, although many may say its bad or unrealistic, I can say they are more than wrong. It was built on a lot of speculation, wormholes being one of them but most of it (funnily enough the blight on earth is the most unrealistic part) is possible. Its one of the most realistic science movies i've ever seen and inspired me in a few ways to pursue this kind of thing. As people who actively play space games, what do you guys think of it?
My love for space is something I could never quantitatively explain with words, I feel like I always wish I could of been born later in the 21st century, or the century after that. I paraphrase from a quote I heard, but we were all born too early to explore the cosmos, and too late too explore the earth. Sad in a lot of ways but space and everything we have learnt out there has inspired me so much. That is why I'm going to become an astrophysicist and its why I love games like StarMade and movies like Interstellar.
That's my cliche meaningful rant over, but anyway, what did you guys think of the movie?
Hesitated to post this

Absolutely fantastic movie, incredible soundtrack. No idea how it didn't win for best soundtrack.

It is easily one of my favorite movies, along with 2001 a space oddysey, if any of you havent seen 2001, you gotta.

That movie is one of the few that actually accurately represents scientific principles. Even Neil DeGrasse Tyson said so. They speculated about wormholes and the inside of a black hole, but besides that, the principles they show are realistic.
I loved that movie. I don't know what those that think it's unrealistic are smoking.

"hurr durr can't go inside a blackhole because you'll die"
So far that's the argument I've seen from people and no one knows if it kills, even recently it's been found that it may be possible to recover information from blackholes.

Actually, whether you would die before you hit the event horizon or not is up for debate. The acceleration imposed by gravity would be thousands of m/s/s, but that acceleration would be applied to both the ship and the astronaut, so it would just feel like he was falling. The problems start to happen when you near the event horizon, which by definition is the point at which matter reaches the speed of light.
Matter CANNOT reach the speed of light. It just can't. Energy can, but as matter nears C, time dilation occurs such that matter actually reaching C would have NO time pass. The faster you go, the slower time goes for you relative to the rest of the universe. A Black hole is not really a feature of matter so much as a feature of time and gravity holding a very large amount of matter in near total stasis.
Nothing reaches the event horizon, not even the matter of the original collapsed star. All of that matter, and all of the matter that gets pulled in throughout the observed life of the black hole is still there, nearing the event horizon but never reaching it. Your spaceship's actual observation would have the astronaut continue on his journey into the black hole at the same rate forever, while time moves faster and faster outside. Everything in the outside universe will turn into a blur, stars going from birth to death in an instant, until entropy triumphs. This process will probably feel to the astronaut as though it takes only a few minutes. after which there will be nothing but blackness.
This is here assuming that he doesn't collide with anything else near the black hole, or encounter any form of intense radiation. While the black hole itself won't emit any radiation, it cannot be ignored that every object moving into the black hole is moving very VERY close to the speed of light, and they won't all enter on the same direct vector. If a rock is headed in an orbit around the black hole in one direction, and runs into one moving the other, the resulting collision would be very energetic. These energies might not be very noticeable from the outside (but they ARE one of the ways we know black holes exist) but they would bathe the neighboring area in STUPIDLY high speed debris and radiation. Good luck spaceman and strange square robot.
A minor note: The matter at the core of the collapsed star would seem to START beyond the event horizon. Since, however, the event horizon is just the calculated point beyond which the matter is reaching the speed of light (were it falling freely) that does not mandate that the core matter actually move that fast. Rather, the core will remain frozen in time at the precise minute of collapse. The state of time dilation imposed by gravity on all matter in the black hole will remain forever, unless something happens to gravity, which is itself bound up in the fundamental nature of the universe.

Well based on the end of the movie the actual singularity in the black hole or the black hole itself was a creation of the fifth dimensional humans to save themselves, at least that's what I believe the point of the end was, so I guess that particular blackhole interior was merely the third dimensional creation of the fourth dimension by the fifth dimensional humans.

Fair enough. I just feel the need to point out that no part of that was science, it was all fantasy. Black holes are a real thing, with real properties. We can observe them. We have never yet observed fifth dimensional humans, or anything we can reasonably attribute to them.

It is fantasy, but I like to think of it as science speculation

Loved the movie for all it's flaws. The best thing for me however, is that it inspired my 16 year old son. It lit his imagination in ways few other things can. He wants to go into astrophysics or astronomy and few things paint those fields in any way other than inhabited by dorky nerds (he also loves Big Bang Theory however which is inhabited by stereotypical nerds). We all went to see it as a group of about 5 teens and me and my GF. Most of the teens were ambivalent going into the movie, but came out excited and talking about the pros and cons and what it meant for several days. No superhero movies can do that to them. So on that front, I think it was a great movie for our time.
All movies take liberties with facts to make them more interesting. DeGrasse Tyson recognized that Interstellar was not perfect, but had enough honesty to make it discussion worthy and enough fantasy to make it exciting. Plus, it was just really done well, which is something you can't say about all to many SciFi films.
If you liked Interstellar, you should check out the new version of Cosmos, which is narrated by NDT. The episode regarding black holes and relativity is excellent (provided you aren't already in the field).

I've watched Cosmos, I love it. I tend to follow a lot of NDT's work, he mainly inspired me into astrophysics, along with stephen hawking's work. You're right though, when I saw it, it only boosted my confidence that astrophysics was the right thing I'm studying. You guys have all seen 2001: A space odyssey right?

That's awesome Kylo. Let me know details about the program at your school.
I saw 2001 in the theaters when it was released - LOL If that tells you anything about me. I was too young to understand much of it though.
