For generations, humans have gazed at the stars and wondered about the ultimate fate of the universe. Will it expand forever ...

Dark energy is estimated to account for between around 68% to 72% of the universe's total energy and matter — its matter/energy budget — meaning it heavily dominates both dark matter and ...

New evidence suggests the universe might not behave as expected, raising questions about the costs of being wrong.

Evidence that the universe is rotating was recently delivered by the James Webb Space Telescope (JWST), which found that ...

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 ...

Dark energy shows up in the mathematics of the universe as Einstein’s cosmological constant, but that doesn’t explain what physically causes the universe’s expansion to speed up.

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 ...

If dark energy is associated with a field that changes with time, on the other hand, we would hope to detect its w value differing from −1 and evolving throughout cosmic history.

Dark energy, the mysterious force thought to be driving the ever-faster expansion of the universe, appears to be changing over time, according to new observations released Wednesday.
