“Teleporting quantum information is now a practical reality,” asserts Deutsche Telekom. The firm’s T‑Labs used commercially available Qunnect hardware to demo quantum teleportation over 30km of live, commercial Berlin fiber, running alongside classical internet traffic. In an email to Tom’s Hardware, Deutsche Telekom’s PR folks said that Cisco also ran the same hardware and demo process to connect data centers in NYC.

I think you’re doing your argument a disservice by comparing it to theory of gravity. But I do appreciate learning about this hypothesis and that there is actual experimentation going on. Thanks again for sharing.

That's not a direct comparison....

It's the generic comparison to show that "just a theory" includes thing we understand 99.9999% of and definitely exists

Until we know absolutely everything, it's still a theory

But we don't have to believe in gravity for it to be real

The point is:

Just a theory

Doesn't mean as much as what people think when they say it
