My only issue is in them choosing to go to Miller’s planet at all. Once they realized what kind of time distortion the planet was under, they should have elected to save Miller’s planet for last. As Brand said after the first wave left then stranded, Miller relatively speaking, had only been there for a few hours. None of her observations were going to be backed by the kind of time intensive observations that would be necessary to determine if the planet would be viable for human colonization. That, coupled with her still theoretical abundance of supplies and the time it was going to cost the people back on Earth, just for them to touch down and speak with Miller, Miller’s should have definitely been their last stop.

it's nice to see someone teaching tyson something new

[JeffWeissenberger]

Watching experts in one field learn something in another field is fascinating. Never stop learning.

[upendravines]

Tyson's "ooh I learnt something new" face

[lkajiess]

We're all so lucky and should appreciate that we are alive in a time where we can listen to Kip Thorne. His interviews are always fascinating.

[Mtaalas]

I love the "Oh, I didn't know that, I learned something new!" face he makes :D
He's still just as interested in learning as he was as a child. We all should be like that!

[YourRoyalMajesty.]

The fact that you are still asking questions and not pretending to know everything, is so beyond refreshing. You are a universal treasure. So much love and respect to you. 💖🕯️

[floridabeachdent]

As much as Neil likes to talk, he listens because he's committed to learning

[owensilvant]

His name was John Scott Russell, and he discovered this phenomenon (the wave of translation aka Russell’s solitary wave) on the union canal just outside of Edinburgh. There is a plaque on one of the bridges along the union canal near the spot where he discovered it (near because no one knows the exact spot) and an aqueduct named after him (Scott Russell aqueduct) a bit further up that also has a sign giving some information on the discovery. The canal has a public footpath along side it so if your in the area you can walk along it, it’s a fairly nice walk, although the Scott Russell aqueduct itself if unremarkable other than the sign.

neils face after saying thats why the crest of the wave gets there is so funny lmao i love NDT because hes not just smart, but smart enough to still be fascinated and excited by new information and the questions he has

[MarzzelHere]

While exaggerated was mostly accurate, man I could watch this movie 3000 times.

[umedjoy]

His face when he was being told he was correct about the crest breaking was adorable. Still like an innocent child, so happy to learn and grow.

[Raida]

Love that NGT just says what he feels doesn't seem accurate, but is very clear what he's basing that on, and that he's not, in this case, a wave expert. He loves to learn!

[shesaidsomething]

Wow, I really wish I could have conversations like this about science/physics/math.

[gregcox]

Potentially the most enjoyable IMAX ride Ive taken BUT… If the water planet has 1.25x Earth’s gravity, how are they able to achieve escape velocity without an additional solid booster rocket which was required when departing Earth?

[court]

My issue was the travel to and from Miller's. They need huge rocket to leave earth which has lower gravity, but just fly off Miller's like an aircraft.

[EverybodyEditsHacks]

What a timeless movie. After 11 years its still able to strike conversation and fascination

[ilpoomatili]

This is why you interview multiple people for documentaries and not just Neil. He's a genius but by no means a god of knowledge.

*me noticing the mummy in the background*💀

There is a small correction I would make to his explanation: the reason for higher parts of the wave traveling faster than the lower part is due to the nonlinearity in the wave (as described by the KdV equation) and not dispersion. This is what causes the steeping as he correctly explained is due to the nonlinearity. As you can imagine, when the top part travels faster than the lower part, the wave steepens. This nonlinearity is balanced by the dispersion (which is just the standard type of dispersion in any wave system) which allows for the solitary wave (soliton) to propagate without distortion to its size, shape, and speed!
