black holes

Just because most black holes are solar-system-sized maelstroms with reality-warping gravitational pulls doesn't mean you can't have one in your pocket! That's right, just in time for the holidays comes the pocket black hole. Designed by scientists at the Southeast University in Nanjing, China, this eight-and-a-half-inch-wide disk absorbs all the electromagnetic radiation you throw at it, with none of the pesky time dilation and Hawking radiation associated with the larger, interstellar versions.

While Robert Frost famously said that he prefers the world to end in fire, physicists have long predicted the universe will end with an icy sputter known as "heat death." Heat death occurs when the universe finally uses up all its energy, with all motion stopping and all the atoms in creation grinding to a halt. And, based on new calculations from a team of Australian physicists, it looks like heat death is far closer than previously thought.

Colliding black holes may prove more interesting to scientists than the immovable object versus the unstoppable force. New data from NASA's Chandra X-ray Observatory has combined with optical images from Hubble to show off a merging black hole pair in all its glory.

The Large Hadron Collider, the giant particle accelerator that's scheduled to begin colliding protons in August, has the potential to produce the long-sought Higgs boson. That elusive particle is a missing link in the commonly accepted model of physics. Observing it would be an important milestone in our understanding of the fundamental forces of the universe.

For years, some scientists contended that black holes swallow everything, including the information associated with the particles they suck up, and that this information can never be recovered. The problem with this idea - the chief proponent of which was the legendary Stephen Hawking - is that it violated a law of quantum mechanics.

It packs 4 million times more material than our sun, but relative to the black holes sitting at the center of some neighboring galaxies, it actually doesn't do all that much. The fact that this black hole, known as Sagittarius A*, kicks out billions of times less energy than others of its kind has made it something of a mystery. But now a team of scientists at Kyoto University suggests that Sagittarius A* may be resting after a far more active period a few centuries ago.

What's cooler than a black hole? Two of them, rotating around and then crashing into one another. And what could be more entertaining than that cataclysmic cosmic dance? Why, one more, of course.

A team of scientists at the Rochester Institute of Technology has simulated the merger of three black holes.

Ultra-high-energy cosmic rays carry more energy than any known particles in the universe, so we should probably all take it as good news that scientists have confirmed that they don't originate in our cosmic neighborhood. In fact, the majority of these rays—which are mostly hydrogen and helium—lose most of their juice on their way towards Earth because they interact with the cosmic microwave background radiation, the energetic leftover of the Big Bang.
