Hello Shawn here, a few years ago I did a
thought experiment that made me realize
a few things about cosmology and it goes
like this
imagine you're of God and you're
observing a star and you have this magic
knob were you can vary the rotation rate of
that star from normal to the speed of
light, so what would be the visual
effects if you turn that knob?
I want everybody that's watching this
video to take a moment to see what their
mind's eye predicts, hit the pause button
if you need to, now when I turn that knob
I turned it halfway and I noticed in my
mind's eye that not much happened it
wasn't until I got close to the speed of
light that it started to go dark and it
got dark at an exponential rate, now I
realized that this is exactly what
Einstein would predict, this graph
illustrates an aspect of Einstein's
theory of relativity so as you can see
when mass approaches the speed of light
it becomes dilated throughout space-time
so the reason why that star went dark is
simply because it wasn't there anymore
from the vantage point of an outside
observer, now studies have shown that at
the center of spiral galaxies velocities
are approaching the speed of light
so this graph applies to a galaxy as a
whole so what does this tell us
as to what exists at the center of a
galaxy because most people nowadays
believe that black holes exist there
well it tells us that instead of the
mass being concentrated at one
incredibly dense place that the mass is
dilated throughout space-time
now Albert Einstein didn't believe in
black holes and in fact nobody did
before the age of television, television
put that image in all of our heads, the
image came first and the belief in them
came later, when I was young not many
people believed in black holes and now
most people do, now if you look at the
image of a black hole it catches your
eye it makes for interesting subject
matter
it looks counterintuitive and the reason
why it looks counterintuitive is because
your intuition is correct, these things
don't exist, there is no event horizons,
now there is a lot of people out there
getting paid to study these things and
they find evidence for what they're
looking for many people believe that
this is an image of a black hole but
what it really shows is what Einstein
would predict in that there is nothing
there now I've explained this to some
friends and family and a common question
is so what would an observer see if they
were near the galactic center, well
that's misleading because there is no
valid XYZ coordinate that an observer on
earth can attribute to the center of our
own galaxy because space-time itself is
traveling at a higher momentum there, you
can't point your finger at something
that is dilated throughout space-time or
more precisely every where you point is
equally valid, if you want to point your
finger towards the mass that exists at
the center of our galaxy all you have to
do is point your finger in any direction
it permeates everything, it's all around
us
now I could talk about this subject for
more hours on end but I think it's
important for now to leave it in simple
terms so that's it in a nutshell thanks
for watching
