For measuring curvature of 3D (hyper) surface we need solid angles instead of plane angles. General relativity (GR), which explains events on the greatest cosmological scale, and quantum mechanics (QM ...

A new theory suggests our universe and a time-reversed twin could emerge together. This quantum approach avoids singularities and offers an explanation for dark energy. Traditional cosmological models ...

A new JCAP study tests an “emulator” to reconstruct the large-scale structure of the cosmos If you think a galaxy is big, compare it to the size of the Universe: it’s just a tiny dot which, together ...

"We already see indications of cracks in the standard model." When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Are we living in a simulation? Well ...

After a century of observations spanning the breadth of the cosmos and theoretical insights that push humanity's vision of the universe to its utmost limits, we can finally, confidently say that the ...

Here’s what you’ll learn when you read this story: A new paper adjusts an equation that defines our universe in response to recent new data. The cosmological constant, which describes how our universe ...

Physicists including Robert H. Dickle and Fred Hoyle have argued that we are living in a universe that is perfectly fine-tuned for life. Following the anthropic principle, they claimed that the only ...

The surface of Earth is finite. We can measure it. If it was expanding, then its size would grow with time. And once again, good ol' Earth helps us understand what the universe might be doing beyond ...

A novel theory suggests that the current expansion rate of the universe is not fixed, but was in fact quite different in the early universe—and that the universe could start contracting at some point.

Our universe appears flat—but this observation still leaves plenty of options for its true shape. In fact, our cosmos could resemble a donut What shape is the universe? This question is far more ...
