there are apocalyptic objects out in the
universe deadly and mysterious what
exactly is a black hole and where do
they come from black holes can sort of
blow your mind I'm amazed that these
objects actually exist totally invisible
yet impossibly powerful even light
cannot escape their most exotic objects
in the universe we don't have the
physics to describe them shattering our
concepts of time and space the black
hole is the place where there is nothing
nothing except gravity
[Music]
you might think a black hole is like
this an object but it's not it's a hole
in the fabric of space now scientists
are on the hunt for black holes what we
can see with our eyes is limited
galaxies can have a lot of dust and gas
but a Space Telescope is equipped with
x-ray vision x-rays bring in too few
regions of the galaxy that would
otherwise be obscured and the death of a
star is revealed the star that gets too
close
what is the black hole then if lays the
outer layers ultimately devouring the
entire star then a radical Observatory
called LIGO detect a black hole
collisions 1.3 billion years ago these
black holes collided the collision
creates a veritable storm and the fabric
of space and time a gravity wave
explodes outward racing at the speed of
light the power is 50 times higher than
the output power of all the stars in the
universe put together it travels over a
billion light years before reaching
birth inside these tubes lasers must
monitor impossibly tiny distances you
are monitoring the motion of mirrors
back and forth by such minut amounts ten
thousand times smaller than the nucleus
of an atom the data reveals a warp in
time and space
that way is a new and direct evidence of
the existence of black holes yet despite
their destructive power could the
universe even exist without them every
galaxy look for one we have found a
supermassive black hole in its center
black holes might well be the key
players in the universe
