Meteorite with CAIs: oldest known solid material in our solar system- the white substance in this meteorite is called Calcium Aluminum rich inclusions (CAIs) and radiometric dating sets the formation time at 4.5673 billion years ago- a few million years older than the rest of the meteorite material and thought to be the first solid compounds formed in the protoplanetary disk before the planets even existed. This substance is most common in carbonaceous chondrites type CV3 as found in this 8 gram sample which was cut and polished on one side. This particular sample was found in 2012 in Northwest Africa. Only the molecules and atoms themselves are older than this CAI material! ➡️ Follow the link in my profile for info on where to get a chunk of meteorite with CAIs and many other amazing items featured here on @physicsfun#meteorite#carbonaceous#chondrite#CAIs#oldestmaterial#deeptime#physics#physicstoy#astronomy#astrophysics#physicsfun#geophysics#geophysicstoy#solarsystem#radiometricdating#inclusion#oldestrock#rockhound#ancient#mineral#geology#science#scienceisawesome
