Unleashed viruses, environmental disaster, gray goo--astronomer Sir Martin Rees calculates that civilization has only a 50-50 chance of making it to the 22nd century.
James Blodgett has setup a new website to discuss the risks that upcoming high energy collider experiments might destroy the earth or even the universe.
Martin Rees argues in a new book that coming technological catastrophes could doom billions and to prevent them, society may need to consider restricting specific types of scientific research. He specifically cites dangers from nanotechnology and supercolliders.
A group of researchers have identified two seismic events that they think provide the first evidence of strangelets or primordial quark matter passing through the Earth.
A team of researchers claims to have found evidence in seismic records for terrestrial impacts of truly strange theoretical particles called strangelets. The particles are said to have ripped through Earth, emerging from the other side virtually unimpeded in their supersonic travels.
FORGET dangers from giant meteors: Earth is facing another threat from outer space. Scientists have come to the conclusion that two mysterious explosions in the 1990s were caused by bizarre cosmic missiles, or "strangelets".
Physicists are debating the risks of a supercollider accidentally creating a doomsday 'strangelet' that could wipe out the Universe, turning it into 'jelly'(?!?!!).
The Economist covers the controversy over the 'strange matter' risk, the risk that a supercollider could cause a chain-reaction that could engulf the world.
Scientists answer fears that experiments at the Relativistic Heavy Ion Collider will create an unstable universe-annhilating 'strangelet'.
Fred Moody looks at the controversy over the new Relativistic Heavy Ion Collider. Some scientists fear that these tests could go wrong and create a black hole that would destroy the solar system.
