What you see up there isn't the black hole or the singularity itself (I'll get to that in a second). Instead, you see a graphical interpretation of
the cosmic rays coming from the center of the Galaxy. Why is this important?
A Black hole is impervious to light except when it absorbs it. It can be likened to a whirlpool in the dark. You don't see it there, but you can feel
it pulling and spinning you around its vortex. In space, the same ideas apply. Astronomers identify black holes by spotting areas of distorted light
from stars. They see a light flash brightly or become dimmer suddenly, and based on calculations, they can predict the passage of a black hole within
that star system.
A black hole is made up of three parts, mainly. At the edge, is the event horizon, which is the accumulation of the newest particles that have been
swallowed by the black hole by entering the field of influence that begins at this point. This is the part that visually gives away the presence of
the black hole, as it is the only part where the particles of light, photons, are still within the spectrum of colors. Like a tornado, you don't see
it there until it accumulates debris such as cattle or houses. Which is how it gets that murky color.
The inner part, the actual vortex, is the implosion of gravity and can be likened to the innermost swirls of a whirlpool. It's generally thought that
space/time consists of curvatures around massive objects that generate powerful gravtiational fields. It looks like this:
As you can see, the heavier (and the more mass within) the body, the bigger the curvature. This is really a representation of gravity, which has yet
to be fully understood. At this point of the black hole, the particles being absorbed are on its way to the heart of the black hole; the
The final and quintissential part of a black hole is the central singularity. A singularity, theoretically, is a single point in space where all that
is consumed by the black hole becomes unified as one object. This is made possible because of the massive forces that generates the pulling effect, as
well as the ultra-heavy bending of localized space. Imagine a curve like the picture above, but at least 10x deeper with a cone-like depression at the
What this means is quite elusive to the scientific community. The significance of a singularity leads to many different possibilities, including a
link to forming protomatter or perhaps even a form of afterlife as eventually, all particles will reach the supermassive black hole sitting at the
center of our Milky Way Galaxy.
Black holes form, usually, when a neutron star (that's a star that collapsed on itself under its own gravitational forces) becomes so densely packed
and heavy, that they implode within themselves even further... think of how when you suck in your gut, your chest tends to inflate as a result of all
that air and mass being transferred from your belly. If you were a neutron star doing this, you don't have a chest for that mass to go, so your belly
continues diminishing in size until *poof* it becomes a hole in your body. The force you exerted to suck in your stomach had become so great, that it
sucked in the stomach itself and everything around it.
Thats all I have to say about that.
