Can Someone Please Explain "Resonance Holograms" to me !

Hello, Hope you're all having a great day so far. I decided to ask a unique question about the film we all saw here for 2 reasons... The first is I have not seen that anyone else here has asked it and if someone could point me to any thread where anyone else did that would be great. If Not...here's my question... The 2nd is, it has been driving me bat sh** and is stuck in the back of my brain like that time YOU struck out at "T-Ball". LOL... I call them "Ressonance Hollograms". TWICE, at least, in this film, David activates what appear to be Holographic "Resonance Memories" of the Space Jockey's Past Physical Actions On Board the Derelict Ship. One time, while David8 is holding the Holographic sphere of EARTH, it seems like all the POWER just immediately DRAINS from the Whole "Sparkling Holographic Orgasm" and then in an instant everything just collapses on itself and goes dark to the pulse of the lone SJ in stasus. What the heck are "Holographic Resonance Memories" and is that even scientifically possible? & Could someone explain to me what was actually going on with that whole star chart Holographic MEMORY Resonance...why were we shown that? Why was it important we saw it, so we could wonder about what the SJ's were doing with those Holograms or was there some meaning and purpose in them {there must have been} that I might have and "prolly" missed? ALL of the crew saw the Holograms of the SJ's fleeing in the tunnels {were "prolly" running from a Deacon, or whatever it was it burst out of one of them that's for sure} so something about the whole process of it and what we were actually seeing needs explaining for me...Help...lol... any help in this regard would be great! Most importantly, after you explain how it is possible...why did it suddenly "shut off"...at the very moment and in the very way it did.
