Ah, thank you Steve. I see from Google she's known as the 'Barnsley Nightingale', from the West Riding of Yorkshire.

Brian was explaining Black Holes which sound terrifying. They have such enormous gravity that they are sucking in matter and compressing it with untold forces. I think he said also that this alters Time but I may have misunderstood. (I have no background in Science)

What if the entire Universe were eventually sucked in to become a tiny nugget of matter with an infinite Mass? Then it might all explode and started all over again with a Big Bang? Maybe this cycle has been going on for aeons, perhaps indefinitely?
Scary!
