But beyond that, there ought to be much more Universe beyond the limits of what we can presently see: the unobservable Universe. Thanks to our best measurements of the part we can see, we're ...

But what lies beyond? What about the unobservable Universe? That's what Gray Bryan wants to know, as he asks: We know the size of the Observable Universe since we know the age of the Universe (at ...

The research team from Jülich, Graz, and Berlin was thus able observe the wave function, which according to the rules of quantum mechanics is in fact considered unobservable. The results are long ...

In 1935, Albert Einstein and Erwin Schrödinger, two of the most prominent physicists of the day, got into a dispute over the nature of reality. Einstein had done the math and knew that the universe ...

As a joint physics-math major at the University of Auckland with no knowledge of astronomy, Charles Alcock stumbled upon a volume of papers from the mid-1960s about rotating neutron stars. A ...

In short, the subject is in principle unobservable to science, not because it exists in another realm but because it is not part of the empirical world. It lies on the edge of things, like a ...

13.8 billion years ago, the Big Bang occurred. The Universe was filled with matter, antimatter, radiation, and existed in an ultra-hot, ultra-dense, but expanding-and-cooling state. By today, the ...

In his new paper, Lieu argues that these singularities, though unobservable, could be the true engines of cosmic evolution, offering a radically different explanation for how the universe expands ...

Increasing the uptake of as yet non-normative (niche) behaviours is crucial to the sustainable energy transition. The authors of this paper test a novel approach to foster the diffusion of such ...

For example, when measurements of stars' velocities at the outskirts of spiral galaxies didn't jive with firmly established ideas of galactic motion, scientists argued that the universe must be full ...
