Hawking says that a black hole will eventually evaporate. This happens due
to the spontaneous emergence of particle / anti-particle pairs near the
event horizon. In some cases, the anti-particle part of the duo gets pulled
into the black hole, therby reducing the mass of the ...

Are Unified Field Theories Justified?

In Bjorken and Drell - QED part 1 I read a statement that one doesnt
use a square rooted  Hamiltonian (H= SQRT/m*2.c*4+m*2.p*2/) in a wave
equation of the Schoedinger type
(–ih.dpsi/dt=H.psi) because after expanding the root in Taylor series

The Brilliance of Our Teachers
    A recent newspaper question and answer column raised an interesting
subject. The query noted that, for a science course at a local school, there
were two instructors. One of those instructors explained the concepts

Has  any 1 considered that quantum dots (which are about 1,000 electrons
encased in a shell) could act as a substitute for anti protons & be combined
in a combustion chamber with protons which would produce a new source of
propulsion. As you may know producing anti protons takes ...

Some of the GR transformations can be explained by two "frames of
reference".
An individual frame (self referenced) and a system frame (group
referenced).

Given that spontaneous particle-antiparticle pair production
can occur at any given point and time is there any
possibility that more than one event like this could occur at
the same point and time.

i have been wondering why electron spin at all.if there is anything
that counters it?

Where Is The Kinetic Energy of a Bullet Stored?
    When a bullet is fired, an explosive charge imparts kinetic energy to
the bullet. That kinetic energy travels with the bullet and is transferred
to the target when the bullet strikes. The question to be answered is where

I heard that a zero mass, zero spin boson would mediate an attractive force.
Does anyone know how that would work?

The Observational Collapse of Einsteinian Physics
    Observations made in the field of Quantum Physics have already
established that the concept that space and time are different aspects of
the same entity - "space-time" is flawed. This concept was based on the
