One of the ways we measure the age of the Earth is using the half-life of uranium. With a half-life of around four billion years, your typical atom of uranium only has even odds of having decayed ...

What these two processes share is baked into the math of each. In fact, in that respect, they're nearly identical. They both involve some stuff (atoms or money) that is either growing or shrinking.

The Standard Model of physics, which explains the properties and interactions of the fundamental particles, does a phenomenal job with the things it gets right, and there's nothing that it obviously ...

Researchers refute the assumption that the decay rate of some radioactive nuclides depends on the distance between the Earth and the Sun. PTB researchers refute the assumption that the decay rate of ...

Here’s a hypothesis for you: radioactive decay varies over time, possibly with a yearly cycle. [Panteltje] decided to test this hypothesis, and so far has two year’s worth of data to comb over.

April 24 (UPI) --The half-life of the isotope xenon-124 is a trillion times longer than the age of the universe. Observing such a slow decay would seem impossible, but scientists working on the XENON ...
