Quantum Entanglement
I don’t know what this means, but it sounds like black magic.

re: Quantum Entanglement
This is a giant step towards using entanglement at our macroscopic level. It offers promise for instant communication across any distance.

Speculating even further, entanglement might be fundamental in nature. If we can determine that objects which are formed at the same time, such as stars and their solar systems, are entangled we may be able to transport things between them via quantum tunneling.

It’s logical to think that what applies in the quantum world can be scaled to the macroscopic world. It’s spooky but it’s natural.

Shouldn't we fix the potholes in our current transport system first?

Theoretically, we could travel between planets instantly?

No. There will always be potholes to fix. That’s an example of what has held humans back for eons. If this then that. IFTTT. Works great for home system routines but not so well for the advancement of sentience.

Well, now that we know entanglement does apply to macro objects we can project that quantum tunneling can as well. In fact, we know that it does. It’s just that the chance you could walk through a wall is so infinitisimally small that it’s just this side of impossible. But who ever thought that entanglement could be demonstrated in the macro world?

If we construct two devices that are entangled and deliver one to Mars, we might be able to use quantum tunneling to send objects or ourselves there instantly, and then return. Now, unlike teleportation, you wouldn’t be a duplicate. You would remain the same.

As for stellar objects that formed together and might be entangled, that’s another consideration altogether. If we can use quantum tunneling to “travel” between them, we might want to use A.I. probes. Wouldn’t want to wind up in the middle of our sun’s twin, for example.

re: Quantum Entanglement
I’ve never been able to get into reading about quantum physics. It’s way over my head and doesn’t make intuitive sense to me at all.

Space has potholes. If we can't fix the Earth ones, we're screwed on the space ones.

I'd like to see some explanation of just exactly what was measured, and what the experiment was. That article was just a bunch of woo-woo.

re: Quantum Entanglement
"Quantum mechanics is like a double-edged sword," says quantum physicist Michal Parniak from the Niels Bohr Institute.

"It gives us wonderful new technologies, but also limits precision of measurements which would seem just easy from a classical point of view."

In isolation, a single particle's properties are an anxious mess of possibility represented by the rise and fall of a wave. It moves in all directions at once. Spins in two directions at the same time. It's all and it's nothing.

re: Quantum Entanglement
You can't send information or physical things with quantum entanglement. I'm not sure where you came up with this, but it's total claptrap.

It’s not intuitive for anyone, even scientists. There are several scientists who are public celebrities because of their sincere efforts to help laymen understand quantum physics, at least as well as they understand it. My favorites are Brian Green, Jim Al-khalili, Sarah Seager and others. Youtube is loaded with short, easy to understand videos about the subject. There are advanced studies, too.

Okay, you were using potholes as a metaphor. I’m an extreme reductionist so literalism is dominant for me.

Still, exploration is part of human nature. We can’t stop exploring the natural world because of human foibles. If we have to fix humanity before we proceed to the next step in our evolution, we’ll never achieve our purpose.

Information can absolutely be sent via entangled particles. Just the act of reversing the spin of one affects the other. On and off, if you will. That’s information.

We will never be able to transmit information faster than light.

And unless you've seen it done, don't say it's possible - you're just speculating.

If you reverse the spin of one of the particles, you've broken the entanglement.

You could try again, but I'll refute every attempt you make because transmitting information FTL with quantum entanglement isn't possible.

You could also just stop and...accept what every quantum physicist out there says.

Even that is information.

You’re not holding a gun while you’re typing that, are you? You seem a bit disturbed.

Boots with spurs, cowboy? I doubt you speak for every physicist.
