It was definitely a bad decision, but it was made for the plot.

There's no way real astronauts wouldn't have thought to do the math on how long she had been on the planet to send all those pings haha

The system would've probably been 1 ping every 10 days or something like that so they would've known that her sending all those pings in 1 hour of planet time meant something was off

Beautiful movie, just finished watching it for the first time since it's release

It’s returning to 70mm IMAX screens around September for the 10 year anniversary.

Time dilation would not affect livability. You would not recognize a time dilation while it occurs without an outside observer. That's one of the issues, extreme dilation is basically Schrodiger's cat and cannot be observed directly.

Gravity warps time. We know this for a fact because the ISS has to reset its clock every couple of months because technically we age slightly slower by nanoseconds or less on Earth than we would in space. But if you’re near a black hole that has many trillions times the mass of Earth, then you age far, far more slowly.

That’s my problem with Interstellar because that should have been the final planet they visited and last resort. They should have had a damn good reason to visit that one first like 100% confirmation of life like an algae or something like that.

the most WTF about that movie was every minute they were out there was equal to decades on earth or more.


No it wasn’t. Each tick was a day passing on Earth, so an hour on that planet was roughly seven years.

so after he left the woman and somehow returned to earth, how is he just gonna hop on a spaceship and go join her to have a life with her, when her bones should have been hundreds of years old and turned to ashes long before he could ever get back to her?


It’s the exact fricking opposite of what you think it is. In the recently deceased astronauts perspective, she just landed there an hour or so ago. About a decade has passed since the Lazarus Mission, so she was killed moments prior on that planet even if it had been a few years on the galactic scale.

quote:

but the way they described time should have made it impossible for his daughter to still be alive even if she lived to be 150 yrs old


It’s clear that you don’t understand literally anything about the movie.

I mean, it had a lot of water.


Still that should have been the last spot they checked due to the time dilation.

If gravity is a constant force, then how can a balloon float or how can a magnet be suspended between two plates in mid air?


A) Magnetism is a much stronger force than gravity.

B) Helium is lighter than Earth’s gravitational forces.

Pretty simple really.

We really have no idea on how gravity actually works and functions at all. We can calculate how intense it would be based on mass, but we still don’t know why it exists. If we did (as the movie shows), then we could defeat gravity and make antigravity boosting.

I think Insane Clown Posse was the first warning sign of the impending Idiocracy we are now experiencing.

Helium is lighter than air, thus it is buoyant. Gravity is just the driving force behind the buoyancy.

i believe they mentioned in the movie they couldn't do that because then they wouldn't have enough fuel left for the return trip (which made that a non-option for cooper because he promised his daughter he'd come back home)

it was the closest to the wormhole so they could either check it first then go to the others but if they went to the others first and came back it'd too much fuel for a return trip to earth

Essentially the same type of reasoning he later chastised Brand about.

IRL people have already been planning missions to Venus to habitate its upper atmosphere.

it was a decision Cooper made because he thought Brand was being dishonest about it being the wrong choice because she was in love with the guy that went to the other planet.


You're mixing up the water planet with Matt Damon's ice planet.

They all agreed to start at the water planet.

I don’t remember them saying that, but I’ll accept this as canon because nothing else makes sense on why they went to that planet first. It by definition did not save them time, that’s for sure.

I believe they went to the water planet because they were still getting transmissions from the first astronaut that landed there.

It wasn't til after they arrived they realized the recency of the transmissions was due to the time slip.
