Excellent questions. ''Matter isn't the only physical thing.'' You're right... and you know what, everything is actually just material. By quantum equations, we even find the space itself is a physical fabric... this must also mean time... ''Can the wave you describe contain information?'' Indeed, in fact, all waves that of form of superpositioned energy, ir even ethereal subspacetime informational waves all contain a value of information. But this is only activated when two waves multiply. A complex conjugate fomrula, and if these waves do not meet with their entangled partners, they will simply cancel out. ''How would that information be "read"? '' There is no intuitive answer, other than to say we read this matter in the mind. ''If no information can escape from it, like a black hole, it might be lost forever.'' Except that superluminal systems can move straight through black holes unaffected, as they travel at a speed that cannot move in real time.
