"The first solid bodies in our solar system have occurred simultaneously, more than 4.5 billion years, says a new study. "
The new findings, by researchers at the University of Copenhagen, could alter current theories explaining the formation of solid bodies in our solar system. Calcium and aluminum-rich inclusions and condrulele are the first solids that have arisen in our solar system. Both are small pieces of meteorites, measuring a few centimeters or even millimeters. Traditionally, to establish the date of formation of solids scientists used the ratio of isotopes of aluminum and magnesium. Thus, they concluded that calcium and aluminum-rich inclusions were the first solids that have condensed out protoplanetary disk. Millions of years later, they were followed by chondrule. Now, the new method used by professionals in Denmark involving the use of two special techniques for measuring isotopes of uranium and lead. Thus, it was established that, in fact, chondrule formed 4.567 billion years ago, long before they settled on previous research. These findings refute what he knew about Condra and demonstrates that the formation of these bodies began simultaneously with the calcium-aluminum-rich inclusions, and that the phenomenon lasted about three million years.
