This idea comes to my mind when I was reading quantum entangle was used by China for hack free communication. China uses quantum keys which was entangle to one another. If communication is hacked, this quantum key will break & entangle will break.
I just consider that this can be used by man on earth to scan topography of other planet directly from earth without sending any satellite.
1) Just consider on Tibet on mountain one scanner is install. This scanner fire stream of quantum entangle keys in stream on Moon surface. We know distance of Moon from Earth. So, we easily find probable time when this stream of entangle keys will hit the Moon ground. Now, just check the keys store on ground just at the same probable time when entangle photon hit the surface & get absorbed. At that time, this entangle will break. Now, just checking store keys on ground we can find (at the time) that Nth number of one key lost its entangle. This will give exact distance of that surface spot from scanner by knowing travel time of Nth key.
This activity can easily repeated & can fire closed placed keys. This will give you location of one spot on moon.
Once we get one spot, this quantum gun will scan second spot near to it. & in some second, this scanner computer will create 3D map of scan surface.
This is not impossible.
I want your comments on this new idea because this has huge potential to develop like FTL communication.
