MILKY WAY'S ORIGINS
Up to half of the matter in our Milky Way may come from distant Galaxies, Astrophysicists have discovered in a first of its kind analysis. Each one of us may be made in part from extragalactic matter. Supercomputer simulations, found an unexpected mode for how galaxies actually acquired matter, intergalactic transfer.
I just love space. We are such nothings in the scheme of things.
