(via PBS Space Time) To observe the quantum nature of gravity and of spacetime itself, we need a particle collider the size of the solar system. Or we could just physics smarter and build one on a lab ...

A new theory suggests that time might not be a fundamental aspect of our universe but rather an illusion created by quantum entanglement. Quantum entanglement occurs when particles become ...

For decades, dark energy has dominated cosmology, thought to account for nearly 70% of the universe’s energy density and driving the accelerated expansion observed in the cosmos. However, ...
