back to article Gravity wave detector gets more sensitive

One characteristic of quantum physics is being used to defeat another, with the aim of making more sensitive gravity wave detectors, in an international project with contributions from the University of Western Australia, the Australian National University, and the GEO600 Gravitational Wave Observatory in Germany. A problem …

    Matter and Mutability

    -----------------------------------------------

    In general relativity, spacetime can be empty of matter or radiation and still contain energy stored in its curvature. Uncaused, random quantum fluctuations in a flat, empty, featureless spacetime can produce local regions with positive or negative curvature. This is called the "spacetime foam" and the regions are called "bubbles of false vacuum." Wherever the curvature is positive a bubble of false vacuum will, according to Einstein's equations, exponentially inflate. In 10-42 seconds the bubble will expand to the size of a proton and the energy within will be sufficient to produce all the mass of the universe

    Does this help

    Planck's constant (denoted h) is a physical constant that is used to describe the sizes of quanta. It plays a central role in the theory of quantum mechanics, and is named after Max Planck, one of the founders of quantum theory.

    Heisenberg showed that the uncertainity in the position of the particle times the uncertainity in its velocity times the the mass of the particle can never be smaller than a certain quantity,which is known as Planck's constant.This limit doesnot depend on the type of particle,or on the way in which one tries to measure the position or velocity of the particle.

    Planck's constant is also used in measuring energy emitted by light photons, such as in the equation E=hv, where E is energy, h is Planck's constant, and v (Greek letter nu) is frequency.

    The value of Planck's constant is:

    6.626068 x 10^-34 m^2 kg/s(Joules/s).

    or does it hinder?
