Was the Big Bang Really an Explosion?

The big-bang theory was first proposed by Georges Lemaitre in 1927
sans its contemporary name, which was coined in the 1950s.
The common name has allowed for the beginnings of our universe
to be too often depicted as a massive explosion similar to that of an
epic supernova. But was our universe really formed in a cosmic
fireworks show? Or was something else at work?
The "big bang" wasn't a "bang" at all, at least not in the common
definition. It didn't explode in a scene of shrapnel and fire, and
there was definitely no mushroom cloud.
The big-bang theory of the universe is derived from Albert Einstein's
general theory of relativity and the idea that the universe expanded
from a miniscule dense collection of energy called a singularity.
There was no bang, just a vast expansion of extremely condensed
material.
So why describe the theory with such a misleading name? To mock
it, perhaps. Sir Fred Hoyle snidely referred to the theory as the
"big bang" with the intention of reducing it to absurdity, and
it stuck.
Hoyle believed, contrary to the big-bang theory, that the universe
itself did not have a beginning, rather the components inside it did.
This is called the steady-state theory, which has decreased in
popularity in light of the common acceptance of the big-bang theory.
If the universe didn't explode into existence, where did it all come
from? According to the theory, the universe-this includes all space,
time, energy, etc.-was condensed into an extremely hot zero-volume
entity of infinite density called a singularity.
In physics density is quantified by dividing mass by volume, meaning
that the equation to determine the density of a singularity divides
by zero. If that doesn't hurt your brain, this will: Because all of space
and time existed within the singularity, the singularity itself did not
exist within space or time.
It cannot be represented and described mathematically, because the
laws of physics that we know do not apply in the singularity.
The universe as we know it (or barely know it) is the result of this
singularity expanding and cooling. Since the singularity itself was
not in a location on the planes of space or time, there is no center
of the universe; everything is expanding from everything else at an
equal rate.
As for the origins of the singularity, or even what existed before
it, scientists are just as befuddled as everyone else.
