Euclid mission has published the most extensive simulation of the cosmos to date. The modeling was based on algorithms ...

The origin of our Universe remains one of the greatest enigmas of science, a question that seems to defy the limits of our ...

The Big Bang is often described as the explosive birth of the universe – a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our ...

Scientists are rethinking the universe’s deepest mysteries using numerical relativity, complex computer simulations of Einstein’s equations in extreme conditions. This method could help explore what ...

Astronomers have long relied on supercomputers to simulate the immense structure of the Universe, but a new tool called ...

For decades, scientists have viewed the Big Bang as the starting point of space and time. But research into cosmic inflation—the lightning-fast expansion that likely occurred before the Big Bang ...

We're often told it is "unscientific" or "meaningless" to ask what happened before the Big Bang. But a new paper by FQxI cosmologist Eugene Lim, of King's College London, UK, and astrophysicists Katy ...

In the earliest moments after the universe was born, everything changed—fast. This rapid expansion, known as cosmic inflation, was theorized to solve problems in the Big Bang model. It explains why ...

Asking what existed before the Big Bang is often dismissed as meaningless, since traditional physics breaks down when pushed that far back in time. Yet a new paper published in Living Reviews in ...

The cosmos is riddled with evidence that the universe began with an unfathomably rapid expansion — even faster than in traditional Big Bang theories — but scientists don’t know why it happened. A ...

Satellites come in all shapes and sizes, but there aren't any that look quite like SPHEREx, an infrared observatory NASA launched Tuesday night in search of answers to simmering questions about how ...
