海外TECH	Engadget	Hitting the Books: Why we can't 'beam ourselves up' Star Trek-style	https://www.engadget.com/hitting-the-books-frequently-asked-questions-about-the-universe-jorge-cham-daniel-whiteson-penguin-163100834.html?src=rss	Hitting the Books Why we can x t x beam ourselves up x Star Trek styleGene Roddenberry was a man ahead of his time accurately predicting the development of fantastical gadgets like flip phones tablet computers Bluetooth and bionic eyes ーeven tractor beams But one technology Roddenberry called for in the s has yet to make it off the screen teleportation It s not only that quot we just don t have enough power quot as Scotty would say we also lack the fundamental knowledge base to make it a reality For now at least In their latest book Frequently Asked Questions about the Universe Jorge Cham and Daniel Whiteson delve into this and a host of other quandaries facing humanity ーfrom whether there s an afterlife why aliens haven t made contact with us yet or if our observable existence is actually a computer simulation nbsp PenguinExcerpted from Frequently Asked Questions about the Universe by Jorge Cham and Daniel Whiteson Copyright by Jorge Cham and Daniel Whiteson All rights reserved No part of this excerpt may be reproduced or reprinted without permission in writing from the publisher If your dream of teleportation is to be here in one moment and then be in a totally different place the next moment then we are sad to tell you right off the bat that this is impossible Unfortunately physics has some pretty hard rules about anything happening instantaneously Anything that happens an effect has to have a cause which in turn requires the transmission of information Think about it in order for two things to be causally related to each other like you disappearing here and you appearing somewhere else they have to somehow talk to each other And in this universe everything including information has a speed limit Information has to travel through space just like everything else and the fastest anything can travel in this universe is the speed of light Really the speed of light should have been called the “speed of information or “the universe s speed limit It s baked into relativity and the very idea of cause and effect which are at the heart of physics Even gravity can t move faster than light The Earth doesn t feel gravity from where the Sun is right now it feels gravity from where the Sun was eight minutes ago That s how long it takes information to travel the ninety three million miles between here and there If the Sun disappeared teleporting off for its own vacation the Earth would continue in its normal orbit for eight minutes before realizing that the Sun was gone So the idea that you can disappear in one place and reappear in another place instantly is pretty much out of the question Something has to happen in between and that something can t move faster than light Fortunately most of us aren t such sticklers when it comes to the definition of “teleportation Most of us will take “almost instantly or “in the blink of an eye or even “as fast as the laws of physics will allow for our teleportation needs If that s the case then there are two options for making a teleportation machine work Your teleportation machine could transmit you to your destination at the speed of light Your teleportation machine could somehow shorten the distance between where you are and where you want to go Option is what you might call the “portal type of teleportation In movies it would be the kind of teleportation that opens up a doorway usually through a wormhole or some kind of extradimensional subspace that you step through to find yourself somewhere else Wormholes are theoretical tunnels that connect points in space that are far away and physicists have definitely proposed the existence of multiple dimensions beyond the three we are familiar with Sadly both of these concepts are still very much theoretical We haven t actually seen a wormhole nor do we have any idea how to open one or control where it leads And extra dimensions aren t really something you can move into They only represent extra ways in which your particles might be able to wiggle Much more interesting to talk about is Option which as it turns out might actually be something we can do in the near future Getting There at Light SpeedIf we can t appear in other places instantly or take shortcuts through space can we at least get there as fast as possible The top speed of the universe three hundred million meters per second is plenty fast to cut your commute down to a fraction of a second and make trips to the stars take years instead of decades or millennia Speed of light teleportation would still be awesome To do that you might imagine a machine that somehow takes your body and then pushes it at the speed of light to your destination Unfortunately there s a big problem with this idea and it s that you re too heavy The truth is that you re too massive to ever travel at the speed of light First it would take an enormous amount of time and energy just to accelerate all the particles in your body whether assembled or broken up somehow to speeds that are close to the speed of light And second you would never get to the speed of light It doesn t matter how much you ve been dieting or working on your CrossFit nothing that has any mass can ever travel at the speed of light Particles like electrons and quarks the building blocks of your atoms have mass That means that it takes energy to get them moving a lot of energy to get them moving fast and infinite energy to reach the speed of light They can travel at very high speeds but they can never achieve light speed That means that you and the molecules and particles that make up who you are right now would never actually be able to teleport Not instantaneously and not at the speed of light Transporting your body somewhere that quickly is never going to happen It s just not possible to move all the particles in your body fast enough But does that mean teleportation is impossible Not quite There is one way it can still happen and that s if we relax what “you means What if we didn t transport you your molecules or your particles What if we just transmitted the idea of you You Are InformationOne possible way to achieve speed of light teleportation is to scan you and send you as a beam of photons Photons don t have any mass which means they can go as fast as the universe will allow In fact photons can only travel at the speed of light there s no such thing as a slow moving photon Here s a basic recipe for speed of light teleportation Step Scan your body and record where all your molecules and particles are Step Transmit this information to your destination via a beam of photons Step Receive this information and rebuild your body using new particles Is this possible Humans have made incredible progress in both scanning and D printing technologies These days magnetic resonance imaging MRI can scan your body down to a resolution of millimeters which is about the size of a brain cell And scientists have used D printers to print increasingly more complicated clusters of living cells known as “organoids for testing cancer drugs We ve even made machines using scanning tunneling microscopes that can grab and move individual atoms So it s not hard to imagine that one day we might be able to scan and then print whole bodies The real limitation though might not be technological but philosophical After all if someone made a copy of you would it actually be you Remember there s nothing particularly special about the particles that make up your body right now All particles of a given type are the same Every electron is perfectly identical to every other electron and the same is true for quarks Particles don t come out of the universe factory with personalities or any sort of distinguishing features The only difference between any two electrons or any two quarks is where each of them is and what other particles they re hanging out with But how much would a copy of you still be you Well it depends on two things The first is the resolution of the technology that scans and prints you Can it read and print your cells Your molecules Your atoms or even your individual particles The even bigger question is how much your “you ness depends on the tiny details What level of detail does it take for the copy to still be considered you It turns out that this is an open question and the answer might depend on how quantum your sense of self is	2021-11-13
