Cosmology Universe may revolve once every 500 billion years — and that could solve a problem that threatened to break cosmology. Astronomy The universe may be dying much faster than we thought.

The universe is undergoing an accelerated expansion, but the rate of that expansion has been a very controversial topic over ...

This could lead to a major paradigm shift in cosmology, akin to the discovery of the accelerated expansion of the universe in the late 1990s. But on this path we may have to reckon, ...

So, what is the speed of light? Light moves at an incredible 186,000 miles per second (300,000 kilometers per second), equivalent to almost 700 million mph (more than 1 billion km/h).

But cosmology – which is trying to understand the evolution of the entire universe using theories that work well to describe other systems – is struggling to answer many of its most fundamental ...

So cosmology used to be a data-poor science in which it was hard to measure things within any reliable precision. And today, we are doing precision cosmology, with percent-level accuracy.

He is a member of the National Science Foundation-funded Atacama Cosmology Telescope collaboration, an international group of more than 160 members who developed the map.

A panel of physicists and astronomers grapple with possible cracks in our modern creation myth, the standard model of cosmology. JWST’s image of spiral galaxy NGC 628, which is 32 million light-years ...

Is cosmology in crisis? A potent mix of hard-won data and rarefied abstract mathematical physics, the standard model of cosmology is rightfully understood as a triumph of human ingenuity.

The Hubble tension is not the only trouble for cosmology. Another one, known as the “S8 tension,” is also causing trouble , albeit not on the same scale. Here the model has a smoothness problem, by ...
