Bellow are a series of analysis that could be studied by the scientists experimenting with XM.Item Hyperthreading
Links could be used to transport items from A to B. The item level would cause XM drainage to the destination portal. If items are to be sent, it would be recommended that the receiving party be ready to recharge the portal if they are to get some amount of items.
Attempting to send the origin portal's key would cause an energy feedback that would destroy both the link and the key.Drop Zones
High level agents (3L8, minimum) could create a "safe drop zone". This area is invisible to the opposing faction's scanners, as are the items dropped in it. However, due to the energies required to establish it, items have their life reduced to 24h tops, and after that they will vanish, decomposed in XM.
Additionally, due to the inherent dangers of using XM as cloaking devices, only one of such drop zones could be built per faction in a 100km radius. And vast amounts of XM must be used due to rapid decay of this "field".Ordinary Matter Hyperthreading
WARNING: COMMON MATTER HYPERTHREADING IS EXTREMELY DANGEROUS AND SHOULD NOT BE ATTEMPTED WITHOUT SAFETY MEASURES!
Just as Item hyperthreading, a live specimen (an agent) could teleport to another portal's vicinity. The action would require the test subject to consume two portal keys (origin and destiny), huge amounts of the XM he has and cause the agent to move to the destination portal.
Due to the way relativistic physics work, the agent would continue to see the origin location with his own eyes, but his scanner would understand and display the correct information (he is not there anymore). Movement through the scanner would be accurate, therefore moving around the location he sees would move him around the location he is.
It must be observed that the agent will constantly have it's XM drained while travelling, and as he is bound to the portal of destiny, he can't move arbitrarily far from it (probably a tenth of the range the destination portal can link to). Failure to remain in the portal's area-of-effect will cause the threading to break, causing XM damage and depletion and scanner disabling, returning the agent to it's origin.Final Considerations
It's is unknown what kind of implications to the world order the confirmation of these theories could cause, but as men of science we must perform experiments, whether they seem possible or not.
