Description:
Cheap Astronomy explores some old horizons
If the Big Bang happened 13.8 billion years ago how come we can still see it?
What we can see is the cosmic microwave background, the CMB, which was a flash of light that actually occurred about 380,000 years after the Big Bang.
How can we observe things that are receding from us at faster than the speed of light?
So, as is well understood by regular Cheap Astronomy listeners – and probably other astronomy podcast listeners, the Universe’s expansion has an additive effect over distance.
