Christophers Nolan's Interstellar

Two obvious ones come to mind (not spoilers as it's in the preview):
1) If the planets go around a black hole instead of a star, why is there daylight?
2) Black holes emit x-rays, not heat. How can there be liquid water on a planet?

There's an easy answer to both of those - the black hole is a supermassive and has a very sizeable accretion disk made primarily of star material that is being slowly sucked into the hole - and that material is still actively putting out light and heat. Lots of it. The accretion disk was easily observable in the film.

Fantastic movie. Yes, there are some glaring science issues but that's to be expected from Hollywood.

Overall it did an excellent job capturing the sheer enormity of space as well as highlighting the challenges we'll face attempting to traverse it. All actors involved, including the one who portrayed Mann, did a good job.

The ending was a little cheesy, but overall, very enjoyable. One of the best movies I've seen in the last 10 years. Perhaps even the best based on that criteria.

9/10.

Also Neil deGrasse Tyson explains the science used for the movie.

I really enjoyed the movie, I saw it in IMAX on Friday.

I was suprised that the movie wasn't in 3D for the IMAX? So much of the film seemed like it was meant to be viewed in 3D?

Spoiler:

I was also suprised to see Matt Damon halfway through the movie appear for about 30 minutes lol.

3D would've killed the awesomeness.

[lasimmon]

Agreed.

I find 3D to be too cheesy.

Star material in accretion disk does no equal continuation of fusion reaction, which is the only thing that'd put out enough light and heat continuously.

Old post, but I'll quote Virginia Tech's physics department.

I've heard that a black hole 'belches' light and radiation whenever something falls into its event horizon. What does that mean and why does that happen?

I'm am not sure what the person is referring to, but I will take a guess. They may be referring to what happens as material falls into a black hole through the action of an accretion disk. As large amounts of material approach a black hole, the material will generally find itself in an orbiting disk-like structure with the hole at the center (i.e., it will look a bit like an extremely crowded solar system). The disk will be extremely hot due to the friction between material with different orbital speeds at slightly different orbital radii. Thus the disk will radiate much light. Much of the incoming kinetic energy of the material is radiated away through this friction-heat-light process. This is what gives rise to the extreme brightness of quasars, and this process is what makes us able to (possibly) find stellar-mass black holes that are part of a double star system. In the latter case, infalling material from the neighbor star makes for the accretion disk around the black hole, and X-rays are emitted by the disk (X-rays are emitted by extremely hot matter, just like the not-so-hot filament of a light bulb emits visible light). In the quasar case, a supermassive black hole (a billion solar masses or so) lies at the center of a galaxy, and gas near the black hole forms an accretion disk around the hole; again X-rays, and other forms of light, are the result.

just watched this tonight, blown away at the in-human depth to it.....some of the parts almost gave me motion sickness envisioning the artificial gravity. If you have not watched this movie yet, DO IT UP YO

[DeleriousZ]

Just watched it again after.. renting.. the dvd...

Not quite as good as it was in imax but still enjoyed the hell out of it. Think this will be one I can watch multiple times. Soundtrack is superb, love the pipe organ

[Thales of Miletus]

I found it to be plodding.

So.. If you are in space for 1hr, then its equivalent to 7 earth yrs? wtf? This movie confused the shit out of me.. LoL

[Tik-Tok]

Gravitational time dilation around black holes is real. The whole giant floating library thing was fiction.

No, the theory present in the movie was that the closer you get to a black hole, the more distorted 'time' becomes. So as the crew approached the BH, what seemed like an hour to them was 7 years to someone not affected by the gravitational effects of the BH.

That was even crappier than that movie with the gigantic blue people.

Gravity on time isn't even that big compared to acceleration. If you got in a ship and accelerated at just 1G for 5 years, turned around and came back (another 5 years for total of 10) something like 35,000 years would have passed here.

I was pissed about the watch. Binary is just a number system on/off. You can't "Write" in it without some sort of table to say A = 111 B = 101 etc that both people know. Even using an ASCII table, type out your name in Binary. It's fucking hard and tedious and time consuming. Now try and convey Einsteins theory of relativity. Now do it without any sort of chart.

It's as absurd as flying into some alien space station, full of organic crazy alien tech and seeing a USB 2.0 port sitting there to upload your alien-killing virus (thanks Independence Day)

And the fight scene - like there isn't enough complexity and conflict, we need a fist fight? Really?
