He's a member of the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX), is studying dark energy from an earlier time in the universe's existence than DESI.HETDEX is also focused on sound ...

If dark energy changes over time, that gives astronomers entirely new theoretical frameworks to explore, from modified theories of gravity to energy fields that naturally evolve throughout cosmic ...

New data suggests dark energy may evolve, challenging the belief that it's constant and forcing scientists to rethink ...

Dark energy can be described as the effect of a negative pressure pushing space outward. We will get more technical, I promise, but let’s start with an analogy to understand this fundamental ...

This dark energy bore all the earmarks of a fudge factor that Albert Einstein inserted into his theory of gravity back in 1917 to explain why the universe was not collapsing under its own weight.
