what is the greatest mystery in all of
science today, well that has to be the
rotation rates of stars in galaxies, in
the 1960s it was discovered that the
stars in the outer bands of galaxies
orbit at about the same velocity as the
stars in the central regions of galaxies,
now this came as quite a shock because
it seems to violate known fundamental
physics, for example if you look at the
planets in our solar system then you see
that the planets that are further away
from the Sun orbit at lower velocities,
Pluto travels much slower than Mars or
mercury so the same rule should apply to
a galaxy as a whole, now there can only
be one explanation for this fact and
that is that there must be dramatically
more mass in the outer regions of
galaxies than what is observed so
scientists have postulated the existence
of dark matter and they believe that
over 80% of the mass in galaxies is this
mysterious form of matter, so what is the
nature of this mystery mass? where does
it come from?
well we'll get back to that in a few
minutes, this graph represents an aspect
of Einstein's theory of relativity so as
you can see the lower line represents
velocity from zero to the speed of light
and the vertical line represented by the
letter Y
that stands for gamma or dilation so as
you can see this dilation effect only
becomes pronounced when an object gets
close to the speed of light, now studies
have shown that velocities are
approaching the speed of light in the
central regions of galaxies
so this graph applies to a galaxy as a
whole, so what does this graph indicate
as to what exists at the center of a
galaxy
because most scientifically minded
people today believe that black holes
exist there, well it indicates that
instead of the mass being concentrated
at one place it is at or near infinitely
dilated throughout space-time so if you
want to point your finger at the mass
that exists at the center of our own
Milky Way galaxy all you have to do is
point your finger in any direction
because according to Einstein that mass
is at or near infinitely dilated
throughout space-time, now this to me is
clearly the source of the mystery mass
that is responsible for the rotation
rates of stars in the outer bands of
galaxies, the mass that we would normally
think of as being at the center of our
galaxy is dilated throughout our galaxy
now I believe that this mass exists at a
higher frequency in space-time, now one
way to put this into focus is to imagine
the mass of the Sun being near
infinitely dilated throughout our solar
system and in that case I think Pluto
and Mars would orbit at about the same
velocity, now I want to point out that
Einstein passed away before the
velocities in the inner and the outer
regions of galaxies was discovered and
the purpose of this video is to
highlight what I think would have been
Einstein's conclusions about these facts
now I could talk for many more hours on
this subject but I think it's best for
now to put it down in simplest terms so
I will answer any questions in the
comment section below thanks for
