if the laser is applied to the cloud, then surely the laser is making new light ?

But the laser applied to the second cloud doesn't, itself, contain the information the messenger atoms do. From my understanding, it only provides the energy to make those messenger atoms emit photons in the pattern stored. So it is making new photons, but the laser photons only provide the needed energy.

Quote:"reincarnate " is a somewhat loose term and thus could be  "reincarnate " turnip.
if the reincarnate  part is bringing a template of wave form back into a photonic mass then maybe the mass is created by the laser, which in all intents and purposes is probably some type of attempt to use light as a form of data encryption rather than looking at light as a time/space property factor.
if ya gits me gist.

whats ya thoughts  around that ?

No such thing as photonic mass. But it isn't a question of mass...it's a question of information pattern. Yes, they hope this provides some new methods for quantum computing and encryption.

Quote:is it still light with no mass ? (i kinda assumed it is not as it is thus a wave print... (funded by xerox?kinda joking & not Re implications of actual usability)

it makes me feel that the nature of the spacial time factor of light has been left sitting on the shelf.

In between clouds, it's not light at all, just a pattern stored in atoms moving very slowly between the two sodium clouds. Within the clouds, it just works like refraction in glass, but on steroids. The speed of light is only c in a vacuum.

thanks, so i gather that the ability to remove the photons enables the ability to code it into a binary function(per say) ?
morse code at close to light speed for processing.

pondering for a moment the reduction in precious metals might be quite significant even if the speed is not substantially greater(i guess the speed is probably faster but do not know).

Quote:Einstein's theory of special relativity sets of the speed of light, 186,000 miles per second (300 million meters per second). But some scientists are exploring the possibility that this cosmic speed limit changes.
The speed of light is constant, or so textbooks say. But some scientists are exploring the possibility that this cosmic speed limit changes, a consequence of the nature of the vacuum of space.
The definition of the speed of light has some broader implications for fields such as cosmology and astronomy, which assume a stable velocity for light over time. For instance, the speed of light comes up when measuring the fine structure constant (alpha), which defines the strength of the electromagnetic force. And a varying light speed would change the strengths of molecular bonds and the density of nuclear matter itself.
A non-constant speed of light could mean that estimates of the size of the universe might be off. (Unfortunately, it won't necessarily mean we can travel faster than light, because the effects of physics theories such as relativity are a consequence of light's velocity). [10 Implications of Faster-Than-Light Travel]

Two papers, published in the European Physics Journal D in March, attempt to derive the speed of light from the quantum properties of space itself. Both propose somewhat different mechanisms, but the idea is that the speed of light might change as one alters assumptions about how elementary particles interact with radiation. Both treat space as something that isn't empty, but a great big soup of virtual particles that wink in and out of existence in tiny fractions of a second.

maybe... black holes accelerate light to a speed faster than we can currently measure.
how could we prove or disprove this idea ?
