    Kansas Legislator Proposes Bill to Outlaw Sustainability Education

    A bill has been introduced in the Kansas legislature this week that would prohibit the promotion of sustainability. Here is a link to the one-page bill: http://www.kslegislature.org/li/b2013_14/measures/documents/hb2366_00_0000.pdf. See report on Bloomberg News.

    Earth's Center Is 1,000 Degrees Hotter Than Previously Thought, Synchrotron X-Ray Experiment Shows

    Scientists have determined the temperature near the Earth’s center to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago. These measurements confirm geophysical models that the temperature difference between the solid core and the mantle above, must be at least 1500 degrees to explain why the Earth has a magnetic field. For more information about this study, see the press release from the European Synchrotron Radiation Facility.

    Ocean Volcanic Rocks Contain Samples of Recycled Crust

    Scientists have long believed that lava erupted from certain oceanic volcanoes contains materials from the early Earth’s crust. But decisive evidence for this phenomenon has proven elusive. New research from a team including Carnegie’s Erik Hauri demonstrates that oceanic volcanic rocks contain samples of recycled crust dating back to the Archean era 2.5 billion years ago. Their work is published in Nature. Oceanic crust sinks into the Earth’s mantle at so-called subduction zones, where two plates come together. Much of what happens to the crust during this journey is unknown. Model-dependent studies for how long subducted material can exist in the mantle are uncertain and evidence of very old crust returning to Earth’s surface via upwellings of magma has not been found until now. For more information about these results, see the press release from the Carnegie Institution.

How much (in meters) is a black hole's diameter? Where do you go if you were to be sucked down a black hole? What would happen to you?

The diameter of a black hole depends on the mass of the original object that becomes a black hole. So the more massive the object, the bigger the diameter of a black hole formed from that object.

If earth became a black hole it would have a diameter of about 0.017 meters, about the size of a marble! Think of how small your bedroom would seem then! Our sun would have a diameter of about 6000 meters, just a little less than 4 miles.

No one really knows what would happen if you were to get sucked into a black hole. The problem is that once you are inside the black hole there is no way to talk to the people outside the black hole. So, we don't know what goes on inside a black hole.

A possibility is that you would slowly be stretched out like a string of spaghetti until you snapped! So stay far away from the edges of black holes!
