Tackling an 80-year-old theory.
ABSTRACT
According to Einstein, General Relativity contains the essence of Mach’s ideas. Mach’s principle can be summarized by stating that the inertia of a body is determined by the rest of the mass-energy content of the universe. Inertia here arises from mass-energy there. The latter, was a statement made by John Wheeler in his 1995 book, Gravitation and Inertia, coauthored by Ciufolini. Einstein believed that to be fully Machian, gravity would need a radiative component, an action-at-a-dis- tance character, so that gravitational influences on a body from far away could be felt immediately. In 1960’s, Hoyle and Narlikar (HN) developed such a theory which was a gravitational version of the Absorber theory derived by Wheeler-Feynman for classical electrodynamics and later expanded upon by Davies and Narlikar for quantum electrodynamics. The HN-field equation has the same type of mass fluctuation terms as in the Woodward Mach effect thruster theory. The force equation, used to predict the thrust in our device, can be derived from the mass fluctuation. We outline a new method for deriving the force equation. We present new experimental tests of the thruster to show that the thrust seen in our device is not due to either heating or Dean Drive effects. Successful replications have been performed by groups in Austria and Canada, but their work is still pending in the peer review literature.

ABSTRACT
The Mach Effect Thruster (MET) is a propellant―less space drive which uses Mach’s principle to produce thrust in an accelerating material which is undergoing mass―energy fluctuations, [1] –[3]. Mach’s principle is a statement that the inertia of a body is the result of the gravitational interaction of the body with the rest of the mass-energy in the universe. The MET device uses electric power of 100 — 200 Watts to operate. The thrust produced by these devices, at the present time, are small on the order of a few micro-Newtons. We give a physical description of the MET device and apparatus for measuring thrusts. Next we explain the basic theory behind the device which involves gravitation and advanced waves to incorporate instantaneous action at a distance. The advanced wave concept is a means to conserve momentum of the system with the universe. There is no momentun violation in this theory. We briefly review absorber theory by summarizing Dirac, Wheeler-Feynman and Hoyle-Narlikar (HN). We show how Woodward’s mass fluctuation formula can be derived from first principles using the HN-theory which is a fully Machian version of Einstein’s relativity. HN-theory reduces to Einstein’s field equations in the limit of smooth fluid distribution of matter and a simple coordinate transformation.

According to the Mayo Clinic, the Nerve regeneration is a complex process, because of its complexity, regrowth of nerves after injury or disease is extremely rare. Nerve damages more often than not are incurable and cause permanent disability, but now the scientist has proved that Advanced 3D printing methods could hold a possible cure for such patients.
To prove the proof of concept, a physically disabled rat was chosen as a test subject. The scientist used a specially designed 3D scanners and 3D Printers to create a custom silicone guide, 3D-printed chemical cues were added to the guide to promote both motor and sensory nerve regeneration. This was then implanted into the rat with surgically grafting it to the cut ends of the nerve. The operation was a extremely successful and the rat showed tremendous improvement in the way it walked within 10 to 12 weeks.
The Lead researcher of this medical breakthrough, Michael McAlpine, a mechanical engineering professor from the University of Minnesota said “This represents an important proof of concept of the 3D printing of custom nerve guides for the regeneration of complex nerve injuries,”
