I was watching Stephen Hawking's Universe on the Discovery Channel and in the first 20 minutes it is stated that by the time the Cosmos was just 10 minutes old it was already thousands of light years in diameter. I thought nothing could travel faster than the speed of light. So how could it expand to thousands of light years in 10 minutes ? I guess there is no speed limit in pure nothing, but then again that throws up more questions.
My head hurts !
