Go Ask ALICE: Learning About the Big Bang

Nearly 14 billion years ago, the universe began with a bang — a big one.

Scientists believe that the universe and everything within it began as an extremely hot, dense “soup” that eventually gave rise to galaxies, stars, planets and life and that continues to expand to this day.

Now scientists around the world are pushing back the frontiers of our understanding about the moment the universe was born using the Large Hadron Collider (LHC), a giant particle accelerator at CERN (the European Organization for Nuclear Research) near Geneva, Switzerland. (more…)

Scientists have long known that large volcanic explosions can affect the weather by spewing particles that block solar energy and cool the air.

Some suspect that extended “volcanic winters” from gigantic eruptions helped kill off dinosaurs and Neanderthals.

In the summer following Indonesia’s 1815 Tambora eruption, frost wrecked crops as far away as New England, and the 1991 blowout of the Philippines’ Mount Pinatubo lowered average global temperatures by 0.7 degrees F — enough to mask the effects of greenhouse gases for a year or so. (more…)
