Thanks for posting, Joe.

One question...

Since the Earth and meteorites all formed from microscopic dust particles and gas, wouldn’t the rate of radioactive decay measure when the dust and gas was created by a supernova, and NOT the date when the dust and gas coalesced into planets and meteoroids?

Thanks for explaining this.

Great question.
If I ever see an answer, will pass it along to you. ;-)
