Teleportation: Impossible?

Ever since its invention in the 1920s, quantum physics has given rise to countless discussions about its meaning and about how to interpret the theory correctly. These discussions focus on issues like the Einstein-Podolsky-Rosen paradox, quantum non-locality and the role of measurement in quantum physics. In recent years, however, research into the very foundations of quantum mechanics has also led to a new field – quantum information technology. The use of quantum physics could revolutionize the way we communicate and process information.

Fourth Spatial Dimension

Try to imagine a 4D hypercube as viewed from the fifth dimension. The shape will be static and unchanging, the hypercube is always a hypercube. Now imagine the shape representing a human being from birth to death as viewed from the fifth dimension. That “long undulating snake” imagery we’ve used really is a gross oversimplification – the complex web of atoms and molecules, water and energy, choices taken and not taken, and all the potential “worldlines” representing a single person is a vastly more complex shape than a simple hypercube. In both cases, that extra dimensional pattern casts a shadow into the third dimension which moves in specific ways: but a rotating hypercube casts a much more predictable and essentially unchanging shadow than the 3D shadow cast by a living and breathing human being!

Euclidean Relativity’s Take On Space And Time

You know how space time are intermingled? Euclidean relativity is another theory which explain our current perceptions regarding space and time. It is just a transformation of minkowskian invariant….below is space time metric in Minkowskian invariant
