What Really Happens if You Fall into a Black Hole?
The world’s largest scientific instrument, the Large Hadron Collider, will be switched on in Switzerland on Wednesday. A few people are worried that the LHC may cause the world to be swallowed up by a black hole, especially when it starts to operate at full force in the spring. What would happen if you fell into a black hole?

Cheap Catalyst Could Turn Sunlight, Water Into Fuel
A new catalyst makes it feasible to split water with solar power.
MIT chemists say the catalyst, used in conjunction with cheap photovoltaic solar panels, could lead to inexpensive, simple systems that use water to store the energy from sunlight.
In the process, the scientists may have cleared the major roadblock on the long road to fossil fuel independence: Reducing the on-again, off-again nature of many renewable power sources.
The catalyst enables the electrolysis system to function efficiently at room temperature and at ordinary pressure. Like a reverse fuel cell, it splits water into oxygen and hydrogen. By recombining the molecules with a standard fuel cell, the O2 and H2 could then be used to generate energy on demand. More>>
