A new research paper reframes the simulation hypothesis, asking whether reality could be simulated and what science can test.

The simulation hypothesis—the idea that our universe might be an artificial construct running on some advanced alien computer ...

Elon Musk and others find it plausible that our experiences result from events in a computer simulation, just like the characters in the Matrix movies. An alternative view, supported by both common ...

We have long taken it for granted that gravity is one of the basic forces of nature–one of the invisible threads that keeps the universe stitched together. But suppose that this is not true. Suppose ...

The simulated universe theory implies that our universe, with all its galaxies, planets and life forms, is a meticulously programmed computer simulation. In this scenario, the physical laws governing ...

Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

Ever since Oxford philosopher Nick Bostrom proposed his simulation argument in 2001, the nerdiverse has attempted to assess the possibility that reality is not really real, that what we experience as ...

Physicists have long struggled to explain why the universe started out with conditions suitable for life to evolve. Why do the physical laws and constants take the very specific values that allow ...

The simulations will be used by astronomers to test the standard model of cosmology. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The world's ...

The first simulation of a wormhole on a quantum computer may not have been an accurate representation of a wormhole after all. Since the original simulation was announced last year, another group of ...

REDSTONE ARSENAL, Ala. — When could a computer simulation substitute for a wind tunnel or flight test? It is the hot topic today in research and development circles. And there are many spirited ...

More stable and efficient materials for solar cells are needed in the green transition. So-called halide perovskites are highlighted as a promising alternative to today's silicon materials.
