Not everything we knew about the universe is wrong. But not not everything. The Dark Energy Spectroscopic Instrument (DESI) ...

Perlmutter, Riess, and Schmidt attributed this deviation to Einstein's cosmological constant, which is represented by the ...

If dark energy is not constant, the effects would be huge. Our current model of the universe, called the Lambda Cold Dark ...

Teleology is the idea that some processes in nature are directed toward a goal or an end. Today, it is commonly asserted that ...

Our current best theories of the universe suggest that dark energy is making it expand faster and faster, but new observations from the Dark Energy Spectroscopic Instrument suggest this mysterious for ...

The DESI experiment shocked cosmologists with a hint that dark energy varies over time. Now, with more data, the conclusions hold up.

However, in 1998, astronomers discovered that it was actually accelerating. The cosmological constant explains this acceleration and is basically an energy density that seems to be an inherent ...

So the Universe should be accelerating much faster than it is if the dark energy is, essentially, the cosmological constant. Still, all the observations to date indicate that it's constant.

The first results from the Dark Energy Spectroscopic Instrument (DESI) are a cosmological bombshell, suggesting that the strength of dark energy has not remained constant throughout history. Instead, ...

Perlmutter, Riess, and Schmidt attributed this deviation to Einstein’s cosmological constant, which is represented by the Greek letter Lambda, Λ, and is related to the deceleration parameter. Their ...
