Galaxy study validates general relativity on cosmic scale, existence of dark matter
|
|
While general relativity describes well the behavior of the solar system, Einstein's theory of gravity and spacetime has not been tested on cosmological scales. Now, a team has analyzed data on 70,000 galaxies to show that the theory is so far the best description of the universe, at least out to 3.5 billion light years from Earth. Specifically, theories without dark matter do not fit the observations.

More maize ethanol may boost greenhouse gas emissions
|
|
In the March issue of BioScience, researchers present a sophisticated new analysis of the effects of boosting use of maize-derived ethanol on greenhouse gas emissions. The study, conducted by Thomas W. Hertel of Purdue University and five co-authors, focuses on how mandated increases in production of the biofuel in the United States will trigger land-use changes domestically and elsewhere. In response to the increased demand for maize, farmers convert additional land to crops, and this conversion can boost carbon dioxide emissions.
