Whether We Live in a Computer Simulation is Testable, Say Scientists
Scientists at the University of Washington speculate that the goal of a super-intelligent civilization would be to create computer programs simulating other universes—ones such as ours.
What's the Latest Development?
Scientists at the University of Washington say they can potentially test whether we are living in a computer simulation known as the The Lattice. The concept of such a simulation, proposed in 2003 by the British philosopher Nick Bostrom, posits that our far-evolved distant descendants might construct such a program to simulate the past and recreate how their remote ancestors lived. "He felt that such an experiment was inevitable for a supercivilization. If it didn't happen by now, then in meant that humanity never evolved that far and we're doomed to a short lifespan as a species, he argued."
What's the Big Idea?
The University of Washington team agrees with Bostrom that super-intelligent civilizations would seek to test all numerical possibilities underlying the quantum vacuum through universe simulations. "If we are living in such a program, there could be telltale evidence for the underlying lattice used in modeling the space-time continuum, say the researchers. This signature could show up as a limitation in the energy of cosmic rays." If they were part of a simulation, the rays would travel diagonally across the model universe, not interacting equally in all directions as they would be expected to.

How a cataclysm worse than what killed the dinosaurs destroyed 90 percent of all life on Earth.
While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.
A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.
We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.
Using advanced laser technology, scientists at NASA will track global changes in ice with greater accuracy.
Leaving from Vandenberg Air Force base in California this coming Saturday, at 8:46 a.m. ET, the Ice, Cloud, and Land Elevation Satellite-2 — or, the "ICESat-2" — is perched atop a United Launch Alliance Delta II rocket, and when it assumes its orbit, it will study ice layers at Earth's poles, using its only payload, the Advance Topographic Laser Altimeter System (ATLAS).
