First, the universe doesn’t expand at a particular .Right now it’s about 70 kilometers per second per megaparsec.It’s free and should be fun, so if you’d like to show up, you can learn more about the whole thing and register here.And for those of you attending the Joint Mathematics Meeting (Comic Con for nerds) in San Diego this year, I’ll be at Springer’s booth on Friday.Most cardiologists appreciate this and will help you get a second opinion.' 'Patients are often fearful of asking about their chances of survival,' says Dr Simpson, 'but finding out the success rates of your procedure and comparing statistics in your hospital to those nationally will help to ensure you get the best treatment.'

Notice the awkward phrasing there: distant galaxies are “getting farther away”, but oddly enough they are Initially, the distance between Red and Yellow is 1, and the distance between Red and Green is 2.
After doubling the size of the “universe” the distances are 2 and 4, respectively. Green would seem to be “moving” faster than Yellow, but in fact all of the dots are sitting still while the space they inhabit expands.
