[THROUGH THE WORMHOLE]
Season 2 Ep. 2

Excerpts:
So, one problem with an infinite universe
that's not just infinite in space
but also infinite in time --
has no beginning --
you have an infinite number of stars.
So the sky would be just completely covered in white,
bright, bright -- so bright that it would fry you.
... So this tells us something.
It tells us we don't live in an infinite universe
that's infinitely old.
13 billion years ago
is the next thing that we we've managed to image,
and it is the after-glow on the Big-Bang.
It's called the cosmic microwave background,
and it's a picture of the way the Universe looked
about 400,000 years after the Big Bang.
... Sop we can't see any further back,
just as we can't see into the Sun.
The cosmic mircrowave background
is a barrier that blocks our vision.
Behind it, there could be an edge.
DARK FLOW:
scientists have discovered a mysterious dark flow of galaxies
all veering off to one side of our universe.
