The Hubble Flow is the motion of astronomical objects due solely to the expansion of the universe. Right now the expansion is increasing space in the universe. In the future, it will either collapse back in on itself, expand forever, or stop…
read moreIf a is the scale factor – the current distance between any two points in space- then the rate of change of that scale factor in relation to the size of the universe is given as : Where is derived from a…
read moreIn our universe, a Constant is a value that remains constant throughout space and throughout time. The Gravitational Constant, G, for example – so far as we can tell – remains regardless of when or where the measurement takes place. So too…
read moreThe Metric Tensor in General Relativity is a Set of 10 parameters ascribed to each point in space, the values of which describe the geometry of spacetime. Metric means “measure,” and a tensor is simply the higher dimensional analogue of vector, i.e….
read moreOn the surface, the concept of Time Dilation seems so strange to us that we imagine its formula must be one of incredible complexity. In reality, its incredible simplicity almost belies the genius required to conceive of it (Minkowski, Lorentz, Einstein). It…
read moreThe four major domains of physics are: Classical Mechanics Relativistic Mechanics Quantum Mechanics Quantum Field Theory Classical Mechanics occurs at what we call “normal” speeds and scales in relation to our everyday experience. Relativistic Mechanics occurs at “normal” and large sizes, but at…

read moreGravitational Force is the force of attraction between all matter.
read moreThe Law of Energy Conservation & Transformation The first law of thermodynamics says that energy can neither be created nor be destroyed, it can only be transferred from one form to another.
read moreGravitation, or gravity, is the fundamental interaction which causes mutual attraction between all things with mass energy.
