Teleportation doesn't depend on travel from A to B through space. Currently we are limited to transmitting information from one ensemble of atoms to another. But matter is really just information.
Then why doesnt a CD get heavier when information is added....or do they? And how much does information weigh?
We are talking about a tiny bit of mass. E = MC^2 C^2 is about 90,000,000,000,000,000. M = E / 90,000,000,000,000,000. E is very small. So M is very very very small. In a similar vein, when you heat a pot of water, it gets heavier because you are adding energy to the system. This occurs due to the increased speed that molecules move - what we call increasing temperature. Because they are moving faster, they gain relativistic mass. But it is only a tiny bit of mass.
https://physicsworld.com/a/information-converted-to-energy/ 0.28 kTln2: At room temperature, that works out to be in the range of a 0.0005 quintillionths of a Joule. 4.2 Joules can raise 1 gram of water, 1 degree Celsius.
In the case of a CD, [I've had to think about this] the compression used during the manufacturing process must result in greater energy in molecular bonds, resulting in increased mass. From physics we know that E = MC^2. If you add energy E to a system, you will measure a mass increase of M = E / C^2. In turn we find that there is always a mechanism of action of preserve this requirement. For memories it is found in the electrochemistry of the brain and chemical bonds. The energy in the chemical bonds result in an increase in mass. For heating water, the increased mass of molecules is due to their increased speed, in the motion we call temperature. For a CD or DVD, it must be due to increased energy in molecular bonds due to compression used to create the pits and lands. It appears that a more general rules is, if we somehow store useful information in a system, we must then find an associated increase in mass or a decrease in entropy. [Okay, now I'm just thinking out loud, so to speak...]
Okay....remember punchcards? They may be before your time but the info was punched into the card....therefore the card weighed less....but the info weighed nothing because it has no mass. A peice of paper weighs something and a pencil mark weighs something ....but the info weighs nothing....just pencil marks on a peice of paper.
Yes, but you have removed information by punching the holes. Convert the lost paper mass to energy, and the energy to information. The information stored is only a tiny fraction of the information lost.
If you punch holes and don't remove the tabs, again you would have to alter the molecular structure of the material. So we would expect to find increased energy stored where the material is torn or cut.
Or...it just isn't in the Realm of physics. May be that immaterial things have no material at all. And information is all in the interpretation. If I transported the information it would mean nothing without interpretation. According to your thinking....if I am hearing you right...the information would weigh as much as me because it is me....and teleportation would be useless
But a peice of paper with the same weight of pencil marks in the form of scribbles would weigh the same.
The mass energy of a single proton is 1.50327759 × 10^-10 joules Just for grins: One bit of information [at room temperature] was indicated to have a value of KTln2 or about 2 x 10^-21 joules of energy. So by that measure, the mass of a single proton represents something around 10^11, or 100-billion bits of information.
I don't follow. Information can do work. That does not require an interpretation. It is something we can measure. Energy is required to do work. So an information-energy equivalence is suggested, just as was a mass-energy equivalence, E = MC^2 This is not my thinking generally. I am just conveying concepts from the cutting edge of physics. The Maxwell's Demon Paradox was fundamental. The apparent resolution of the paradox is profound in its implications.
You weigh as much as the information that is you now. We are all just information. Maybe we really are living in a computer simulation. Quantum teleportation, in regards to something like a transporter, connotes the idea of using "spooky action at a distance", where laws of physics are satisfied through what appears to be magic, even between entangled elements light-years apart - instantly. And it all involves the seeming transfer of information. The idea is that your information [you] would be here, and then you would be there, with no travel in between. On this I have to defer to a basic rule I was taught in physics. You cannot transmit useful information through entanglement and beat the speed of light problem. I would have to think a bit to remember how it all plays out. But I know it was realized to be impossible to make such a thing as an entangled telephone system. Actually you treat it more like a telegraph system. But as far as I can remember, fundamentally it can't work.
It would have to transport the personal atoms, as at any given moment every atom in the universe is accounted for, therefore it wouldn't be possible to assemble people at the point of transfer with spare matter. At least that would be my understanding, and why time travel would never be possible...
Well, my understanding is that the quantum entanglement direction is not actually moving information. The separation that occurs is by normal transport. So, please fix me on that if I'm wrong. Or, I'd be interested in what other mechanism you're thinking about.
True. Also, if you could move the pencil particles around on the paper so that it carried more information, it wouldn't weigh more.
There is information involved but not that can be used external to the system. The fact is, we don't know how it works. You might want to review Bell's Theorem. "No hidden variables" means that the information about the state of the system did not exist until a measurement is made. If you make a measurement on one of a pair of entangled particles, the second one instantly takes on a unique value. So by some mechanism, information about the first particle magically reaches the second.
It is helpful to be specific. We have two electrons entangled such that conservation of spin requires that one be spin up, and the other spin down. We further require that they are separated by a great distance. Then we measure one of electron's spin. It could be spin up or spin down. Until we make a measurement, it exists in an undefined state. So does it's counterpart. They are neither spin up or spin down, or they are both [Schrodinger"s Cat], until we measure it. As soon as we measure, let's say we get spin up. At that moment, the other electron immediately assumes a spin down orientation. Bell showed that no unique spin exists until we make a measurement on one of them. Then, spin is uniquely defined for both electrons and conservation of spin must be satisfied.
HAHAHAHAHAHAHAHA...I love this stuff, this sounds like it could be a very fun thread. I'll start by saying that I believe that Star Trek science and technology is far more rational and logical than Star Wars science and technology, which often has no rhyme or reason. No, not all of Trekkie STEM is 100% logical all the time but most of it tries to be. Lucas based STEM is nonsensical in the extreme. BOOM!!! So there...mic drop.
