In cosmic terms, 200,000 years is a blip.
Compared to the rest of the universe, our solar system is just a teenager — it formed 4.5 billion years ago compared to the universe'sAccording tobased on a new analysis of ancient meteorites, it took less than 200,000 years for the whole Sun and solar system to form. By comparison, scientists believe the human species has been walking the Earth forFast-Forward
The new timeframe is significantly shorter than what astronomers expected. Based on studies of similar star systems, scientists expected the process to have taken 1 to 2 million years. "Previously, the timeframe of formation was not really known for our solar system," lead study author and Lawrence Livermore National Laboratory cosmochemist Greg Brennecka
. "This work shows that this collapse, which led to the formation of the solar system, happened very quickly, in less than 200,000 years.", like researchers date different layers of rock on Earth, and found sections linked to the process of star assembly that formed over 200,000 years. "If we scale this all to a human lifespan, formation of the solar system would compare to pregnancy lasting about 12 hours instead of nine months," Brennecka said. "This was a rapid process."
