The Second Friedmann Equation describes the acceleration or deceleration of the expansion (or contraction). It describes the forces pushing or pulling on the expansion.

read moreThe stress–energy tensor is a tensor physical quantity. A vector quantity is a tensor quantity that contains two components. A scalar quantity is a tensor quantity that contains only one component. These are special cases of tensors, being the simplest kind. But…
read moreIt is notable that time dilation is not limited to kinetic or gravitational time dilation, but by virtue of the unification of gravitation and acceleration by the Equivalence Principle of General Relativity, by acceleration as well. In all cases, Time Dilation is…
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 moreA gravitational field is a model used to explain the influences that a massive body extends into the space around itself, producing a gravitational force on another massive body. Thus, a gravitational field is used to explain gravitational phenomena, and is measured…
read moreA Force is an influence that can change the motion of an object via a push or pull deriving from interaction with another object. A field is a mathematical set of numbers for every point in space which can be operated on…
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…
