Lange was best known as co-leader of project “Boomerang,” which in 1998 used a telescope, carried over Antarctica by a balloon for 10-and-a-half days, to study the so-called cosmic microwave background – a gas of thermal radiation left over from the embryonic universe.
He was 52.
A flat universe also supports the “inflation” theory that the universe underwent a rapid expansion in a fraction of a nanosecond after its birth.

In 2006, he became a senior research scientist at NASA’s Jet Propulsion Laboratory and was appointed chairman of Caltech’s physics, mathematics and astronomy division in 2008. Big Bang physicist Lange dies at 52 |

January 27, 2010 AP Lange had three young sons, according to the university. Lange and Italian team leader, Paolo De Bernardis of Rome’s La Sapienza university, were awarded one of Italy’s 2006 Balzan prizes, annual awards of 1 million Swiss francs, for contributions to cosmology. (Boomerang was short for Balloon Observations of Millimetric Extragalactic Radiation and Geophysics.) He was appointed a full professor in 1994 and was named the Marvin Goldberger Professor of Physics in 2001. The experiment showed the spatial geometry of the universe is flat and supported theories that it will expand forever and not collapse upon itself. Physicist Andrew Lange, co-leader of an international team that produced a detailed image of remnants of the Big Bang showing the universe is flat, has died in an apparent suicide, police say. “It appears to be a suicide,” Dewar said. Lange checked into a hotel last Thursday and the next morning housekeepers found him dead, apparently due to asphyxiation, said police Detective Lieutenant John Dewar. “It is an incredible triumph of modern cosmology to have predicted their basic form so accurately,” Lange said when the research was published in 2000. Lange was a physicist at the California Institute of Technology. University President Jean-Lou Chameau notified the institution in an email that Lange apparently took his own life on Friday. They largely matched predictions and suggested that scientists are on the right track in understanding the earliest moments of the universe, its age and the amount of so-called dark matter that holds galaxies together. He graduated from Princeton University in 1980, received a PhD from the University of California, Berkeley, in 1987, and was a visiting associate at Caltech in 1993-94. Lange was born on July 23, 1957, in Illinois. |
The observations were considered the first detailed images of the infant universe, according to Caltech.
Lange recently resigned as chairman of the Division of Physics, Mathematics and Astronomy, Caltech said.
