SchrodingerZ writes: "Scientists at Berkeley Labsin California have theorized a new idea for a clock that can remain ticking even after the death of our universe. The idea is to create a four dimensional crystalline structure that is unaffected by third dimensional havoc. It would work by having the ‘electric field of [an] ion trap holds charged particles in place and Coulomb repulsion causes them to spontaneously form a spatial ring crystal. Under the application of a weak static magnetic field, this ring-shaped ion crystal will begin a rotation that will never stop,’ says Berkeley faculty Xiang Zhang. ‘The persistent rotation of trapped ions produces temporal order, leading to the formation of a space-time crystal at the lowest quantum energy state.’ It is considered to be 4-dimesional because ‘a spatial ring of trapped ions in persistent rotation will periodically reproduce itself in time, forming a temporal analog of an ordinary spatial crystal. With a periodic structure in both space and time, the result is a space-time crystal’. Because this space-time ‘crystal’ would already be at the lowest quantum state possible, theorists believe the structure could continue on after the rest of the universe fades and destroys itself ( thermodynamic equilibrium). Though the idea is mathematically sound (proven by nobel prize winner Frank Wilczek), constuction and manipulation is still only theoretical."
The computer can't tell you the emotional story. It can give you the exact
mathematical design, but what's missing is the eyebrows.
