Welcome to PhysicsWiki,
29,201 articles in English
The universe we live in is a place of vastness beyond human conception. It has principles of operation that can be divined by observation, analysis, and calculation. It is the goal of this organization to attempt to set an order to those principles in a fashion that results in the unification of the principles into a coherent calculable science.

The Alcubierre drive or Alcubierre metric (referring to metric tensor) is a speculative idea based on a solution of Einstein's field equations in general relativity as proposed by theoretical physicist Miguel Alcubierre, by which a spacecraft could achieve faster-than-light travel if a configurable energy-density field lower than that of vacuum (i.e. negative mass) could be created. Rather than exceeding the speed of light within its local frame of reference, a spacecraft would traverse distances by contracting space in front of it and expanding space behind it, resulting in effective faster-than-light travel.(Full article...)

  • ...that your watch would run slower when orbiting a black hole than it would on Earth?
  • ...that Aristotle's ideas of physics held that because an object could not move without an immediate source of energy, arrows created a vacuum behind them that pushed them through the air.
  • ...that nuclear fusion reactions are probably occurring at or above the sun's photosphere; it is a process called solar surface fusion.

  • ...that neutron stars are so dense that a teaspoonful (5 mL) would have ten times the mass of all human world population?
  • ...that every year, the Moon moves 3.82 cm away from Earth?
  • ...that Neptune was discovered by its gravitational pull on Uranus?

Suggest a fact
PhysicsWiki welcomes the addition of Original, Theoretical & Experimental Material. The articles in this area should not be considered as reference material. They are the real reason for the existence of PhysicsWiki. PhysicsWiki is a place where we can explore ideas regarding any area of physics in a collaborative fashion. This area is not a BLOG but it is for placing challenging views about the science of physics up for anyone to examine.
The synopsis below is an open dialog regarding the defination energy
Merriam-Webster's Full Definition of ENERGY

1 a : dynamic quality <narrative energy>

 b :  the capacity of acting or being active <intellectual energy>
 c :  a usually positive spiritual force <the energy flowing through all people>

2: vigorous exertion of power : effort <investing time and energy> 3: a fundamental entity of nature that is transferred between parts of a system in the production of physical change within the system and usually regarded as the capacity for doing work 4: usable power (as heat or electricity); also : the resources for producing such power

A Proposed New Definition (NOT EXPLANATION)
  • A field of existence having finite boundaries, that are infinitely variable and exhibiting infinitely variable topology. The field occupies no more than 2 dimensions of space and has a constant entropic condition.

  • An energy field will exhibit polar properties due to its motion in space/time. Those properties are positive on the surface that is exposed to the direction of motion and negative on the surface that
 is opposite the direction of motion. These fields appear to exist always at right angles to the direction of propagation. 
  • Entropic condition is caused by interactions between different energy fields and between energy fields and matter. These interactions are caused by the polar relationships of energy fields.
 Since all fields are constantly in motion, one will always exhibit the characteristic of repelling any other field that is directionally opposed to  it.
  • Energy fields are always in motion relative to our perception of the universe, or we may be in motion relative to energy fields.

  • The topology of an energy field may have an almost infinite variety of configurations. A visual example would be to consider an impossibly thin sheet of plastic wrap.
 It is stretchable and can be shaped in a  variety of ways, but it only has two surfaces and a finite boundary. 
  • The behavior of all energy fields is that of a somewhat elastic surface that has infinite properties of flexibility.
