Researchers recalculate the age of our solar systeem.lead lead dating{pb-pb}is among most widly used radiometric dating technics to determine the age of really old things such as age of Earth or Solar systeem.However recent advances in instrumentation now allow scientist to make more precise measurments that promice to revolutionize the ages of some samples calculated with this technique.then what about our present calculated age of solar systeem ..is it wrong or correct..

Hmm, the last one I saw was 4.6 billion years (plus/minus some million years I suppose, dating isn't very precise, especially not with stuff as old as this). I think they got that from dating samples from meteorites or the moon. New instruments often give new opportunities for better and more accurate measurements, but it doesn't mean that they'll get a "new" age. They might end up with the same but with less uncertainty.

yes there are confusions reagarding this counting among scientific community.some one say it is 4.566 billion years back and some one says 4.567 billion years means again there is diference is of one milion years ..which is not small na ..!

Well, 1 million years is a lot when you talk about dating things, say, 10-50 million years old. But with 4.6 billion years I think it is pretty accurate. I've definitly seen worse measurements ;-) (I've probably made them too ...)

Yeah. it is about 5 billion years, before the Earth exists!

Oh I hope other Mylot members knows the answer here. I'll check and see this discussion always because I also want to know the answer. ^_^
