In every bit of nothing, there is something. If you zoom in on empty space and take out all the planets and stars and galaxies, you might expect a pure vacuum, but you’d be wrong. In­stead you would ...

The cosmological constant is presumably an enigmatic form of matter or energy that acts in opposition to gravity and is considered by many physicists to be equivalent to dark energy. Nobody really ...

The far distant fates of the Universe offer a number of possibilities, but if dark energy is truly a constant, as the data indicates, it will continue to follow the red curve, leading to the long-term ...

The cosmological constant, which explains how and why the universe is expanding, has been previously described by astrophysicists as “the worst prediction in the history of physics” due to its ...

Researchers have found a new way to measure dark energy – the mysterious force that makes up more than two-thirds of the universe and is responsible for its accelerating expansion – in our own cosmic ...

The great Russian physicist and Nobel laureate Lev Landau once remarked that "cosmologists are often in error, but never in doubt." In studying the history of the universe itself, there is always a ...

The current "standard model" of the cosmos, its history, and its evolution is called the Lambda Cold Dark Matter (LCDM) model — but the supremacy of this model, in which lambda represents the ...

Teleology is the idea that some processes in nature are directed toward a goal or an end. Today, it is commonly asserted that teleology is a remnant of antiquated ways of thinking about causation, and ...

The universe is approaching the midpoint of its 33-billion-year lifespan, a Cornell physicist calculates with new data from dark-energy observatories. After expanding to its peak size about 11 billion ...

We know that the universe is getting bigger. And we know that the speed that the universe is getting bigger is also getting bigger. The standard assumption is that the acceleration rate is itself ...

Licia Verde receives funding from the AEI (Spanish State Research Agency) project number PID2022-141125NB-I00, and has previously received funding from the European Research Council. Licia Verde is a ...
