Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to [email protected]. Is the whole universe just a simulation?

In 2024, researchers completed the first-ever map of the circuitry of a fruit fly’s brain. Despite its diminutive size, the organ packs almost 500 feet of wiring and 54.5 million synapses into the ...

What would it mean to simulate a human brain? Today’s most powerful computing systems now contain enough computational firepower to run simulations of billions of neurons, comparable to the ...

The simulation hypothesis—the idea that our universe might be an artificial construct running on some advanced alien computer—has long captured the public imagination. Yet most arguments about it rest ...

Thomas Anderson – otherwise known as Neo – is walking up a flight of stairs when he sees a black cat shake itself and walk past a doorway. Then the moment seems to replay before his eyes. Just a touch ...

New research from UBC Okanagan mathematically demonstrates that the universe cannot be simulated. Using Gödel’s incompleteness theorem, scientists found that reality requires “non-algorithmic ...

The idea that we’re living inside a simulation, as popularized by “The Matrix” franchise, has piqued the interest of scientists for decades. In 2003, philosopher Nick Bostrom proposed in a highly ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Despite how it may feel some days, we probably aren’t stuck in a ...

Scientists have developed a groundbreaking tool called Effort.jl that lets them simulate the structure of the universe using just a laptop. The team created a system that dramatically speeds up how ...

If such a simulation were possible, the simulated universe could itself give rise to life, which in turn might create its own simulation. This recursive possibility makes it seem highly unlikely that ...

For two decades, scientists have seriously considered whether we’re living in a simulated universe. A computer scientist at the University of Louisville explores ways that humans could try to hack our ...

Git isn’t hard to learn. Moreover, with a Git GUI such as Atlassian’s Sourcetree, and a SaaS code repository such as Bitbucket, mastery of the industry’s most powerful version control tools is within ...
