Entire star cluster thrown out of its galaxy
The galaxy known as M87 has a fastball that would be the envy of any baseball pitcher.
It has thrown an entire star cluster toward us at more than two million miles per hour.
The newly discovered cluster, which astronomers named HVGC-1, is now on a fast journey
to nowhere. Its fate: to drift through the void

Turbulent black holes grow fractal skins as they feed - physics-math - 28 April 2014 - New Scientist
Feeding black holes develop a fractal skin as they grow. That's the conclusion of simulations that take advantage
of a correlation between fluid dynamics and gravity. "We showed that when you throw stuff into a black hole, the
surface of the black hole responds like a fluid – and in particular, it can become turbulent," says Allan Adams
at the Massachusetts Institute of Technology. "More precisely, the horizon itself becomes a fractal."

Dark Matter and Dark Energy Mysteries: Do Neutrons Hold the Key? | Space.com
Neutrons bouncing in Earth's gravity are helping to shed light on two of the greatest mysteries in the universe,
dark matter and dark energy, researchers say. Dark matter is an invisible substance thought to make up five-sixths
of all matter in the universe. The strength of its gravitational pull apparently helps keep galaxies from spinning
apart at the speeds at which they whirl. Dark energy, on the other hand, is the mysterious stuff that scientists
believe is pushing the universe apart, driving up the rate at which the cosmos expands. Investigators suggest
dark energy could make up about 70 percent of the universe.

How Big is the Universe? | Space.com
As technology has evolved, astronomers are able to look back in time to the moments just after the Big Bang.
This might seem to imply that the entire universe lies within our view. But the size of the universe depends
on a number of things, including its shape and expansion. Just how big is the universe? The truth is,
scientists can't put a number on it.
