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 ...

Data from dark-energy observatories indicate universe may 'end in a big crunch' at 33 billion years old
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 ...
As I finished my PhD in 1992, the universe was full of mystery – we didn’t even know exactly what it is made of. One could argue that cosmologists had made little progress in our understanding of ...
A new study by Anowar Jaman Shajib, associate member of the Center for Astronomy, Space Science and Astrophysics (CASSA) at Independent University, Bangladesh (IUB), suggested that dark energy—the ...
According to physics, the universe and everything in it can be explained by just a handful of equations. They’re difficult equations, all right, but their simplest feature is also the most mysterious ...
The vacuum of space isn't actually "empty"; it teems with particles that pop in and out of existence, giving the vacuum an energy of its own. But here's an embarrassing fact about that energy: it ...
The theoretical framework underlying gravitational waves may have to be revamped to account for dark energy and the acceleration of the expansion of the universe. That’s the conclusion of researchers ...
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 ...

Quantum cosmology with final states can explain the accelerated expansion of the universe
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 ...
Physicists are now celebrating the 100th anniversary of the cosmological constant. On this occasion, two recent articles highlight its role in modern physics and cosmology. Before becoming widely ...
A new study of one of the universe's fundamental constants casts doubt on a popular theory of dark energy, scientists say. Dark energy is the name given to whatever is causing the expansion of the ...
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 ...
