yes, agreed. the idea of keeping anything larger than an atom entangled for anything longer than a second over any distance over an inch seems like a colossal almost impossible task with today's technology

i was only doing a thought experiment

in the realm of way out there then: i wonder if you could entangle a number of "copies" of yourself: dozens, hundreds, millions

you just sort of disperse throughout the universe (not interacting with anything, i know, basically impossible by today's standards)

but in an instant, if you, or someone outside, decides one "copy" of you should be the one that coheres at a given place: boom, you're there

just an interesting thought with interesting ramifications- you (or someone else) doesn't have to decide out of dozens or maybe thousands of destinations... until the very last moment. that's a pretty exotic form of "travel"

it's called desalination and it's a common mundane technology

"boiling the oceans" makes me think you have no fucking clue about the kind of scale we're talking about here

if every nation exerted every single drop of it's GDP building desalination plants, we wouldn't make the tiniest of dents in the oceans genius

if they desalinate ocean water for drinking purposes, the question is what to do with all that salt

answer: process it and take out all of the economically important trace elements, not just lithium

The total lithium content of seawater is very large and is estimated as 230 billion tonnes, where the element exists at a relatively constant concentration of 0.14 to 0.25 parts per million (ppm),[40][41] or 25 micromolar;[42] higher concentrations approaching 7 ppm are found near hydrothermal vents.[41]

sure, this would put lithium at a high price point, but not that high if the desalination and concentration process is mostly solar powered and on a massive scale for drinking water purposes

i get it: they are guaranteed the same white noise, which is fine for encryption purposes (and know if someone snooped, because that would render their white noise dissimilar)

but there is no preserving the integrity of a particle/ wave for transportation purposes

thank you, i learned something

that's an excellent analogy, thank you

and you are correct, there's no real movement, only a collapse to a single frame of reference

however, for the intents and purposes of outside human observers, haven't you instantly blinked across light years?

we have no technology remotely capable of this, but:

1. a quantum entangled version of yourself moves away from you (at "normal" speed, less than c)

2. say... many light years away (i know, i said we have no technology remotely capable of this, bear with me here, just a thought experiment)

3. the "copy" of you can't violate c, but at the last moment, one version of you interacts with its surroundings, collapsing you to that single copy. such that you have achieved instantaneous transportation across light years of distances

doesn't that happen faster than c?

There was of course a lot of cgi in the movie but ...

the cgi was there to tell a story- not to render action scenes.

An action movie with rendered action doesn't connect emotionally.

When those guys swinging around on poles showed up- i had a gut reaction.

Making an action film and then using cgi for the action scenes usually lacks just enough realism that I don't have an emotional reaction to the action. That emotion is why I'm willing to put down good money to see a movie.

MM:FR was decent. As everyone else says- so little acting and so few words- but combined with incredible action scenes and a lot of genuine stunts. I probably won't ever see it again but I don't feel like I wasted my money.

Human beings were created by water to transport it uphill.
