Quantum Telescope

[vlaiv]

If I'm not mistaken, as far as color goes it's more "when" that is questionable.

Heisenberg uncertainty relationship stands for time/energy - and since color is energy (wavelength) - then if you know when - you can't know color, but if you know the color, then you can't know when it's that color

But you said 'NO' so how can anything that can't be, be any colour you like?

All light based telescopes are quantum telescopes as photons are the most enigmatic of quantum particles.

Sounds like a free pass to say that what ever I type in the quantum world could be true. Turns out that 87.23950% of my calculations are made up on the spot.

But in the quantum world they may well be correct.

A free pass - that is exactly it, until of course it is not!

i'd say neutrinos are even more enigmaticer than photons.

We would need to build a new detector at CERN to decide  - The ENIGMANTIC Detector, I would love to read the funding bids for that one.

While elusive and puzzling they don't have the range of behaviour of photons. 

However,  it's just a subjective option on my part.

If quantum telescopes are possible will they come in bright red anodised finished?

You won't be able to tell until you unbox it.

The problem I have with entangled photons and other particles is, which is entangled with which?

I've heard of charmed or strange particles, but never saw a cute one

If a particle is cute enough, some other particle is bound (pun!) to be charmed by it, and before you know it they won't be strangers anymore. After a few drinks, they will probably get entangled. The uncertainty is if that entanglement will last for a half life or just be a one night stand. According to Heisenberg, the energy they put into it may determine that.

There was Beauty, but I think it's now usually Bottom.

It looks like you're on Top of things.

It must be summer recess, with not much else to do. This thread is getting entangled beyond recognition.

Sorry, but I don’t think I understand exactly what you’re suggesting here.  As I understand it, entangled particles cannot be used to send information instantaneously from one place to another. 

At first I thought you were suggesting looking at entangled particles (photons presumably) arriving from a distant star system. Even accepting that some photons might be entangled, I am not clear that you can separate or distinguish entangled photons from the normal ones. Not with a detector at one end anyway. Maybe a proper physicist can help with that one.

Then I wondered whether you envisaged sending to the distant star system a probe capable of creating entangled particles, half of which would be directed towards earth.   Well, as already said, no information can be sent this way - including the instantaneous sending of images.  You might as well send the probe to take images to relay back. Assuming you’re willing to wait a few thousand years for the pics. 

Or maybe you were just having a laugh.😆 

No, I wasn't actually having a laugh. I just got carried away with an idea that seemed too good to be true.

I simply did not appreciate how readily an entanglement link could be broken when one end is forced.

Come to think of it, there would not even be a negative kind of signal since someone at the receiving end wouldn't know if the link was still in place or not.
