1 trillion is already difficult to visualise, but 105 trillion!?

Just so you have an idea of how big 1 trillion is, a trillion seconds is about 31,710 years. But 105 times that!? Madness.

Cool quiz! Only one I was really unsure of was the show.

Facts that might help: a trillion is a million million.
