Exploring Vacuum Instability

Scientists are currently exploring the concept of vacuum instability.  What does this mean?  Well, they believe there is a chance that…  Billions of years from now, a new universe could open up into the present one and replace it.  It all depends on some very precise numbers related to the Higgs boson particle that researchers are currently trying to pin down.

If the calculation on vacuum instability holds, it would revive the old idea that the ‘Big Bang’ Universe we can observe today, is merely the latest version in a permanent cycle of events…  Continue reading Why the Universe may be Inherently Unstable

The Field Equations of General Relativity

Keeping It Relatively Simple

The Einstein Field Equations of General Relativity are vast and complex, but they can be written with deceptive simplicity.  Using modern notation, the field equations can be formulated as

\boldsymbol G = \frac {- 8 \pi G}{c^4} \boldsymbol T   Continue reading The Field Equations of General Relativity
