Why theano UFOs

I covered my take on a lot of this is my book:

The limmits of light speed IMO will be nixed once we are able to impose a bubble of 3 dimensional space outside normal space.

One proposal is here:

At the rate we are learning to manipulate subatomic particles, magnetic fields, etc, I don't see anything insurmountable in creating ships to "cruise" the universe in the not too distant future.

However, would one want to? Lets say one could create a nano-bot the size of wasp with such capabilities and the software to instaneously create the apparent sensory perception that one is in the bot.

Entangled electrons are connected in such a way that specific properties of the electrons remain synchronized regardless of the physical distance between them.
Here's a brief explanation of one formulation of the EPR paradox: Take a particle, say an electron, which has two fundamental quantum states (spin up and spin down). We can arrange to produce two electrons in such a way that their states are correlated or entangled, so that if one has spin up, the other necessarily has spin down.The EPR effect arises from a particular property of quantum mechanics, which says that a system can exist in a superposition of states. In this example, we treat the two electrons as a single system. Therefore, we expect two possibilities: electron 1 has spin up and electron 2 has spin down OR electron 1 has spin down and electron 2 has spin up. But quantum mechanics also says that before we measure the spin of either electron, the system can, in a sense, exist in both of the possible states at the same time (i.e. in a superposition of the two possibilities). Thus, each electron will be found to have a definite spin value only when we actually measure it.Now, suppose we separate the two electrons by a long distance, then measure the spin of electron 1. We will find it to be either up or down, with say a 50% chance of each outcome. Suppose it has spin up. Then, it turns out that no matter how far away electron 2 is, it will instantaneously be found to have spin down. But the result for electron 1 was not determined until we measured it, so how did electron 2 know to be the opposite? It seems that somehow electron 1 must have communicated its spin result to electron 2 at faster than the speed of light (contrary to relativity).The key to resolving the "paradox" is that even though the electrons are widely separated, they must be still treated as a single quantum system due to their entanglement. In a sense, all the information needed by both electrons is already contained in the system (though the measurement result is NOT predetermined - there are no "hidden variables"). It seems that this type of faster-than-light "communication" is permitted by relativity since it cannot lead to causality violations.

Sooooo.......one could be "In the bot" cruising the Orion nebula or exploring the sands and waterfalls of some world orbiting in the Pliedades while sitting safely in you den. Or a corporate laboratory.

Just a thought.

Once you've filled up your first Oort cloud, the next Oort cloud over just isn't that big a leap.Best,- Joe
