Quantum mechanics and general relativity are fundamentally incompatible for reasons that relate to views of the world that simply cannot be reconciled. In general relativity, space and time are ...

Physicists have recently proposed a test to determine whether or not loop quantum gravity exists. Before understanding the importance of the test (or the test itself), first we need to understand what ...

This article has been updated to correct my confusion of loop corrections to quantum gravity with loop quantum gravity. Dark energy is the mystery du jour in cosmology. It is the name given to ...

CPS should be called on any child (boy or girl) who wasn't allowed to play with Hot Wheels. The orange racetracks and cars were perhaps the most important items in any kid's toy box. The best part ...

Just one of the things that supercolliders such as CERN’s Large Hadron Collider and Fermilab’s Tevatron might find is evidence for something called “Quantum Gravity Loops”—which we won’t even try to ...

A 500-meter train loop can comfortably provide the simulation of gravity. People would be in sleeper cars if they needed the overnight one-gee. Sleeper cars on trains have been around since the early ...

Loop quantum gravity (LQG) is a non-perturbative, background-independent approach to quantising spacetime that seeks to merge the principles of quantum mechanics and general relativity. In this ...

Quantum simulation plays an irreplaceable role in diverse fields, beyond the scope of classical computers. In a recent study, Keren Li and an interdisciplinary research team at the Center for Quantum ...

Many in the space community are very concerned about low-gravity, no-gravity and radiation for people living for long durations in space colonies on planets, moons, asteroids or orbital bases. These ...

The Lego Fairground Collection already includes a roller coaster. Now, Lego is adding a Loop Coaster that is one of its tallest at just over 3 feet and it includes “an innovative elevator tower for ...
