tickets please ticket Dania we actually
live an incredibly precarious place in
the cosmos we live on the outer layers
of a ball of molten rock that is itself
a tiny speck around a small star that’s
one of 200 billion stars in a galaxy
that’s spinning its way through universe
of 200 billion other galaxies it’s there
are all sorts of very fast very
dangerous objects racing around out
there in the galaxy and if they come
into our neighborhood they will do some
very real damage just about all these
objects reflect light so chances are
we’ve see them coming from a very long
way off there are other projectiles we
would never see coming and one of those
is called a primordial black hole a
primordial black hole does not reflect
any light therefore it’s essentially
invisible to us what time are we
beginning to date 30 minutes
a primordial black hole is different
from these huge black holes we often
read about it’s a theoretical space body
that we believe is left over from the
Big Bang it’s a very very small object
it can be smaller even than an atom
and yet it’s incredibly dense and heavy
possessing perhaps one-tenth the mass of
the earth and with those properties if
one of them was to collide with the
earth it could shoot through us like a
bullet through an apple
see Harry look out at the sky are you
seeing this
you
