Flashes of femtosecond laser light, lasting just a few trillionths of a second, have made it possible to observe new magnetic ...

A new AI accelerates laser simulations for X-ray experiments by a factor of 250 and is revolutionizing modern physics.

Quantum computing’s edge looked closer after a hard physics problem seemed beyond classical machines. But a new result shows ...

For almost as long as Lawrence Livermore has existed, scientists have been experimenting with materials to learn what happens to them under high pressure. In the brief instant of a high-explosive ...

Simulating the nonlinear optical physics that underlies ultrafast laser systems is computationally demanding—a practical ...

Physicists have shown that simulating models of hypothetical time travel can solve experimental problems that appear impossible to solve using standard physics. Physicists have shown that simulating ...

Is gravity created because we're in a simulation? The double slit experiment and linear models show that particles can change back in time when someone observes it. After Trump became a problem for ...

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 ...
