I'm not that great with statistics. Could someone who's better than me put these odds in to perspective for us?
For example if the chance of a collision (transaction) 9.7x10-29 how would that compare to say winning the lottery (US powerball)

Winning it 2 days in a row? Everyday for a week? Month? 700 years?

Flipping a coin and getting heads 1000 times in a row? or 100000 or flipping it every 10 seconds and getting heads  for 6 months?

I realize this number is huge but I think it would be interesting to figure it out in those scenarios just to have something that shows really how rare it is.
