Some NASA scientists studying galactic clusters have come across a very weird phenomenon. The galaxies they're studying appear to be rushing toward a spot in space much like air rushing toward, and out of, a pinhole in a balloon:
Sasha Kashlinsky, a senior staff scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, has been studying how rebellious clusters of galaxies move against the backdrop of expanding space. He and colleagues have clocked galaxy clusters racing at up to 1000 kilometres per second - far faster than our best understanding of cosmology allows. Stranger still, every cluster seems to be rushing toward a small patch of sky between the constellations of Centaurus and Vela.
The implication of this is that these galaxies are pouring out of our universe through some sort of a rent in the cosmic horizon. They appear to be drawn by something beyond our space-time world. Is all the matter in our universe draining out? What, exactly, are these galaxies draining into? What sort of entity lies beyond the boundary of space and time?
No one knows. What we do know, what we seem to be learning anew with every fresh observation, is that the universe is a very strange place.
