This has been the prevailing explanation for the origin of the universe since the 1960s. But despite its prominence, this theory is challenged by new investigations into concepts like dark matter and dark energy, which invisible particles scientists ...

Gough’s blowtorch theory and the evolutionary cosmology is, he suggested, “more exciting and attractive right now than the mainstream theory, ‘lambda cold dark matter’, which, after 50 years of constant tweaking, still didn’t see any of this coming”.

Shocking’ results from a major astronomical study have raised doubts about the standard model of cosmology, forcing scientists to consider new ways of understanding dark energy and gravity

A bold new theory suggests the universe didn’t begin with a single Big Bang, but instead unfolds through a series of ultra-fast, invisible bursts called “temporal singularities.” These fleeting events flood space with energy and matter,

These series of step-like bursts happen so rapidly that they are difficult to observe as these singularities wink in and out of existence.

In simplest terms, the rate at which the universe expands on paper doesn’t match actual astronomical observations. That speed—called the Hubble Constant—is measured in units of kilometers per second per megaparsec (km/s/Mpc),

Physicist Richard Lieu first explored the idea that gravity could exist without mass—now he’s got a new cosmological model that eschews the need for dark energy.

In the search to understand how the universe came to be, a new theory is rewriting the script. Instead of one massive, fiery birth like the Big Bang, this idea suggests the cosmos has been growing in sudden,

Physicists have proposed a new model of space-time that may provide the 'first observational evidence supporting string theory,' a new preprint suggests.

Whether we are simply characters in an advanced virtual world is a much-debated theory, challenging previous thinking about the universe and our existence.

Quantum theory started with a bout of hay fever, and went on to transform our view of the universe – but its legacy isn't complete

Fan theories are the lifeblood of communities and fandoms. It’s what keeps a franchise alive between content bursts, even when that franchise is as massive as Star Wars. Frankly, there’s so much content from the Star Wars universe that it’s pretty much impossible to avoid creating a few fan theories along the way.
