Special relativity says they will move through time slower in relation to us because they are traveling faster in relation to us. General relativity says they will move through time faster because they are further away from gravitational pull. The difference in calculations must be added together to get the actual result.

I cannot wrap my brain around this. Ugh

Think about spacetime like a blanket stretched out between 4 people each holding a corner. Newton tells us that the shortest path between two points is a straight line. If the blanket is pulled taut, the shortest path is still a straight line.

Now imagine a softball placed in the middle of that blanket. If you can picture it, you can see how the blanket dimples where the softball is. Now, the straight line between 2 points (say, if you were to roll a matchbox car) on the blanket has to curve along the blanket because of the dimple. The closer to that dimple, the more exaggerated the curve. That dimple is the gravitational well.

Now imagine a bowling ball instead of a softball. The heavier object creates a deeper well, more gravitational pull for our curved line.

The black hole creates an "infinitely" deep dimple in the blanket such that the distance it takes to cross into the dimple and back out is also "infinite." The curved line then is "infinite."

Maybe that's a bad analogy...

As the person falling into the black hole, you will just zip past the Event Horizon. If you are looking at the outside universe, you will notice that it will suddenly fast forward to the end of time as you pass the Event Horizon though.

See, this is the only thing I'm confused about at the end of Interstellar. To everyone on Earth, shouldn't Cooper still have been "stuck" at the event horizon of Gargantua even after 100 years or whatever it was?

I think under our current understanding, yes, Cooper would basically be "stuck" just above(?correct spatial orientation?) the event horizon to anyone outside of the black hole.

Not just anyone on Earth, but anyone outside of the black hole gravity where it really slows down time.

But seeing as somebody built the teseract space for him to operate inside the black hole, then collapsed it, and dumped him just outside Saturn, my guess is they also pulled "the stuck Cooper" out of time too.

Not just that, but as I mentioned above, you'd be "spaghettified" meaning your atoms would be pulled apart like strands of spaghetti because your feet are closer to the gravity of the black hole than your head is.

But yeh the explanation to all of this is - future mankind developed some technology or technique around all that.

Yes.... although I don't know the specifics of entering a wormhole, but that should still apply.

According to Wikipedia, because the black hole was a super massive blackhole, one wouldn't experience spaghettification.

I think you would eventually as you approach the singularity. You just wouldn't at the event horizon.

quote:

---

The point at which tidal forces destroy an object or kill a person will depend on the black hole's size. For a supermassive black hole, such as those found at a galaxy's center, this point lies within the event horizon, so an astronaut may cross the event horizon without noticing any squashing and pulling, although it remains only a matter of time, as once inside an event horizon, falling towards the center is inevitable. For small black holes whoseSchwarzschild radius is much closer to the singularity, the tidal forces would kill even before the astronaut reaches the event horizon.

---

I guess Interstellar's take is he wouldn't be killed before hitting the event horizon and I guess once he was in the event horizon, all bets were off.

Another interesting thing, which the movie got at least partially right is that outside the event horizon, you can move around in space, but must go forward in time. Inside the event horizon, that reverses. You can move around in time (which Coop was doing) but you must move towards the singularity. That's for a plain non-spinning, non-charged black hole though. If it's spinning and charged, it's possible to avoid hitting the singularity and exit the event horizon. But you end up in a different universe. From what Kipp Thorne said about the black hole in the movie, it was rotating close to the speed of light.

DId it bother anybody else that they had to have an Apollo 13 launch to get into Earth orbit?

They showed later in the movie that the two rangers and two landers were capable of getting out of a lower and higher gravity than Earth on their own. If fuel was the issue have the lander refuel in orbit.

Getting off earth is one thing...getting to Saturn is another.

Got an email from iTunes saying "No Time For Caution" was available to download because it hadn't been included with the album originally.

I liked the music.

Finally saw it. Loved it. I believe they must have tried Plan c and they showed them trying plan D at NASA when M. Caine shows MM that the world is doomed. For those who tl;dr'd, plans c & d are from early pages of this thread.

Also, I was sad that the lifeforms from the early script did not make it into the movie

Question about relativity....

Miller is supposedly only been on her world a few hours. Since she's been going nearer to the speed of light, time has slowed for her. What does this do to her radio signal? Shouldn't this increase her wavelength considerably? NASA should not have years worth of data at this point...

This might have already been discussed, but the "interviews" of the old folks describing the dust were real, I think.

If you've ever seen Ken Burns' documentary on the dust bowl, there are dozens of these old timers describing how they lived and what it was like. It appears Nolan used actual people/experiences for this part of the movie, which I thought was genius.

I just saw it. I liked it a lot but my issues were with the ending, and I am not wading through 11 pages but I bet this has been discussed.

What is Brand still on Edmond's planet to begin with? Why didn't Murphy tell NASA to go get the 12 Lazarus people some time while Cooper was in the Black hole? They obviously had the resources and technology to do it.

And also why does Cooper care so little about Murphy's family and they don't care about him? Seems odd.

I think most of them were real. Ellen Burstyn (old Murph) seemed like the only actor/actress in there.

None of them had ever met him so they felt no real connection. It was also probably strange to see their grandfather/great grandfather walk in and he's like 40 years old.

It's their grandfather, who they've never met, and has essentially time traveled, not to mentioned saved the human race.

He should be kind of a big deal.

I think they did at some point; but Brand probably spent years - if not decades alone on the planet.

My guess is Murph was employing a little bit of time travel herself and trying to save Brand years of isolation...with babies.

Well, given the time dilation on Edmunds' planet, Amelia wouldn't have been there more than a matter of months (or less) by the time Cooper reaches her.... at least that was my understanding

So.....are they gonna, like, kiss and stuff when he gets there?

I found that odd too - here you have a guy who traveled through a black hole, a worm hole and to several distant planets...but he walks in and gets a big "meh" from all the frat star dads.

Was Edmunds planet that close to the BH to experience that kind of time dialation? I know the wave planet was of course, but I didn't know there was the same issue with Edmunds.

I don't think there necessarily has to be a romantic relationship between Amelia and Cooper. It could develop over time.
