Taking one cheesecake at a time, pipe a cobweb design by piping four
straight lines to make an «asterisk» and then connecting the lines by piping two
circles, one
circle around the outer
edge of each cheesecake and another
circle halfway to the center
of each cheesecake.
According to B. S. Sathyaprakash, a theoretical physicist at Cardiff University, UK, and a senior LIGO researcher, this pattern suggests that the orbits
of the black holes were nearly circular, and that LIGO probably had a bird's - eye view
of the
circles, looking almost
straight down on them rather than
edge - on.
