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?

When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording the diffraction patterns formed by shining a laser beam through it. At the ...

What if gravity, the force that holds your feet to the ground and binds galaxies together, is much more than a fundamental law of nature? What if it’s actually the smoking-gun clue that suggests ...

First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...

Researchers from the Faculty of Engineering at The University of Hong Kong (HKU) have made a significant discovery regarding quantum entanglement. This phenomenon, which has long been viewed as a ...

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 ...

For "Laser wavelength", the colors in the gradient and the dot does not match. For both "Laser wavelength" and "Grating line density", the range of the slider UI is not clear.

Rizwan Virk owns shares in Google, and in various video game companies. He is also a venture partner in Griffin Gaming Partners, a venture capital fund dedicated to investing in video game-related ...

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 ...
