Quantum Entanglement - instantaneous transfer of information?

23 posts in this topic

Hey folks,

I'd like to get some opinions on a couple blog posts I wrote regarding the nature of photons - specifially, quantum entanglement, where particles appear to communicate with one another faster than the speed of light.

http://www.brentpeters.me/wp/2012/08/989

I'm not a physicist, but my posts attempt to explain some ideas commonly labeled as "spiritual" using scientific terms.

Some of the later parts get into AI, the nature of free will, and other potentially interesting topics. A complete table of contents can be found in the first post of the series, here: http://www.brentpeters.me/wp/2012/08/936

cheers,

Brent

Spooky action at a distance does not transmit information. Physics is still a bi*.

Quantum entanglement may instantaneously change the properties of the two entangled particles, but it cannot (and nothing can) transmit information faster than the speed of light.

How can anything ever hope to go faster than the speed of light then? How could something like warp drive become reality?

Negative mass?

Well, nothing can travel through space faster than light (In reality, the speed of light is the cosmic speed limit, it's only known as the speed of light because that was what was first measured).

As for the warp drive, it's theoretically possible but there are... problems. Namely the insanely high energy requirements, needing exotic matter, steering or stopping it would be pretty much impossible and radiation inside the bubble would be devastating.

Warp drives work by warping space, such that the area inside the bubble is pulled/pushed forward, but the objects inside the bubble don't move relative to their bubble of space, so they can go "faster than light", by virtue of never actually moving.

Of course what happens when something enters the warp bubble from outside? can you create a stable warp bubble without destroying what's inside it?, etc. All very interesting questions.

nasa is currently testing a scaled version of the warp drive tech after a recent finding that made the energy requirement go from the mass of jupiter to under a thousand pounds

There is no "warp drive tech", it's all just maths at the moment.

I love it how they throw these theories into equations, like that does ANYTHING, Math is NOT the universal language they think it is, it's basically just mind scribbles in equation form.

Math is the language of nature itself, and yes it can form viable theories, but theories also need to be tested.

We CAN change the laws a' physics captain!!

They are working with scaled tech to warp space-time 1/10,000,000 parts. It's just math at the moment, but the tech is slowly being developed.

So if a warp drive system does allow a net result of faster-than-light travel (without an object actually travelling through any space faster than the speed of light of course), but we never find a way to transmit pure information faster than the speed of light, then we could conceivably end up with a 'sneaker net' communication system, whereby a distant colony would send a message back to earth via a small probe that could move faster than a radio signal by use of a warp drive.

Well nothing can go faster than C because "things" have mass. And accelerating any mass above C requires infinite energy. There's really no exception to that math/physics/nature.

Unless there is some sort of possibility of "converting" the mass to zero using neutral particles. Though, that might just cause everything to annihilate. Even so, you could only get to C, but still not faster. Going faster would require negative mass.

quantum entanglement is real physics, it can be done. but doesn't it mean something regarding time travel? anyway, thanks for starting this thread, it's an interesting topic, i've always been a fan of the space ansible :)

i doubt it can be done for massive objects like a spaceship, but for comms..very likely. in Avatar they use it for low bit rate comms, but the manual says the transmission energy costs mean even in the mid 21st century they can do little more than tweet using the ansible :D

Tachyon04s.gif

Because a tachyon always moves faster than light, we cannot see it approaching. After a tachyon has passed nearby, we would be able to see two images of it, appearing and departing in opposite directions. :shiftyninja:

Scientist John Singleton made a machine in 2008 called a polarization synchrotron and presented the work and results to the American Astronomical Society:

Most people think Einstein said that nothing can travel faster than the speed of light, but that's not really the case, Singleton said. Einstein predicted that particles and information can't travel faster than the speed of light ? but phenomenon like radio waves? That's a different story, said Singleton, a Los Alamos National Laboratory Fellow.

Singleton has created a gadget that abuses radio waves so severely that they finally give in and travel faster than light. The polarization synchrotron combines the waves with a rapidly spinning magnetic field, and the result could explain why pulsars ? which are super-dense spinning stars that are a subclass of neutron stars ? emit such powerful signals, a phenomenon that has baffled many scientists, Singleton said.

The concept of phenomenon traveling faster than light has been discussed in the back alleys of the scientific community since the 1970s, but observations were based on strange aberrations, like the distorted images of stars as they traveled near the speed of light, said Mario Perez, a Los Alamos scientist who worked with Singleton on the project.

"Radio astronomers found sources that looked like things were traveling faster than light, but they were not truly superluminal, like this is," Perez said.

"If you take a laser and shine it on the moon and swing it rather gently, for example, the spot on the moon travels faster than the speed of light," Singleton said. "If an effect can do that, it makes you wonder if you can do things with light to get the equivalent of a sonic boom." That's what the faster-than-light radio waves ? more scientifically known as superluminal transmissions ? do. They're the light version of a sonic boom.
