(3) Cosmic Contour

There's Black Holes, for example. Cosmologists speculate that
they are usual in the centers of galaxies. Our contemporary
astrophysical technology helps us feel around the conclusion
that there is such a thing as a Black Hole. However, one does
not want to get close to such a cosmic beast. According to
general relativity, a Black Hole possesses a gravitational field
so powerful that nothing, but nothing can escape its pull. This
includes matter and even light. Nothing escapes--maybe.

Some theorists believe that a Black Hole might actually be
a wormhole. Thus it is a kind of an inner tunnel where one
might travel from one point to another point in the universe.
Hard to figure, however, if everything that enters such a hole
is destroyed. On the other hand, maybe matter seemingly
dumped into a Black Hole arrives at the other end of the tunnel.

Regardless cosmic theories are fascinating There's the String
Theory that combines general relativity and quantum mechanics
into a quantum theory of gravity. This theory also involves
additional dimensions to our usual three spatial dimensions
plus our one dimension of time. And further developed String
Theory moves into what is deemed the Holographic Principle.
More on that as we get into Quantum Theory.

The basis of Quantum Theory can be summarized in three
propositions: (1) In the subatomic world, few things can be
predicted with 100 % precision; however, accurate predictions
can be made about the probability of any particular outcome;
(2) One has to work with the probabilities rather than certainties,
because it is impossible--for an observer--to describe all
aspects of a particle at once as to its speed and location; and
(3) Electromagnetic energy, such as light or heat, does not
always behave like a continuous wave--rather it is grainy
because energy can be transferred only in quantum packages,
and thus light has a dual character, sometimes displaying
wavelike aspects and in other circumstances as particles.

And the magic component in this cosmic story, whether it's about
us or whether about the whole universe, is Energy!

In 1900 Max Planck had originated the theory of Quantum
Mechanics, which is a theory of energy as emanated in discrete
packages. Soon Albert Einstein took Planck's idea one step
further, assuming that light was quantized. And later David
Bohm, a premier physicist, known as the "Father of Quantum
Mechanics," believed that this underlying background of Energy
to be the plenum of the universe. Bohm likened this plenum,
this immense background of Energy. to be one whole and
unbroken movement that he called the "holomovement."
