In fact bluntness is his hallmark, but he means no harm.A questor, he's wherever the action is and if there's an ideal attached to it, so much the better.Purcell’s findings are based on supercomputer simulations conducted for his Ph. dissertation completed in 2010 at the University of California, Irvine, a member of the University of California High-Performance Astro Computing Center (UC-Hi PACC).The fact that a dwarf galaxy—called the Sagittarius Dwarf for the constellation in which it is seen from the earth—is in the process of colliding and merging with our own Milky Way has been known for seventeen years.The Sagittarius man sets the fast pace and is something of a gambler.“I was making these kinds of film shorts, they were sometimes a minute, or two or three minutes, back in the 80s. The ones with the character I’d created, Sometimes Jones, kept on getting reviewed here in L. because I was showing them in local coffeehouses and movie places, and that’s where a guy came to me said he thought the films were great, and so we started a commercial venture together.
He's the lively one to be found in a group, always at the centre of a debate, he'll be the body to say what he thinks directly, if a little tactlessly.
There was just glimmer of people interested at the time in little movies like these, but a lot of the new cable channels needed ‘product’ and I remember they ended playing on Z Channel a lot, late at night, and TV shows like “So, he had this idea of me making film shorts. I made several of these films before he ran out of money, and then he disappeared.
and this was pre-Youtube, and he paid me a couple of bucks. And I kept making films, but If I don’t’ have any money, then I just go back to ones that I have…
Up to now, most astronomical research has focused on the effects of the collision on the Sagittarius dwarf itself, because the vast gravity and tidal forces exerted by the large Milky Way is ripping the smaller galaxy apart into long streamers of stars wrapping around our own Galaxy.
In computations for his dissertation research, however, Purcell explored a new and important question: what effects have the repeated collisions of the dwarf galaxy, with its invisible but massive halo of dark matter, had on the larger Milky Way itself?
