New research from Griffith University's Centre for Quantum Dynamics is broadening perspectives on time and space.
The universe is not spinning or stretched in any particular direction, according to the most stringent test yet.
Researchers have shown how a bizarrely shaped black hole could cause Einstein's general theory of relativity, a foundation of modern physics, to break down. However, such an object could only exist in a universe with five ...
Are humans unique and alone in the vast universe? This question—summed up in the famous Drake equation—has for a half-century been one of the most intractable and uncertain in science.
Our brains struggle to comprehend how big the universe is because everything here on Earth, and even the Earth itself, is very small when compared to the immense scale of the universe.
Astronomers using NASA's Hubble Space Telescope have discovered that the universe is expanding 5 percent to 9 percent faster than expected.
Describing the universe requires fewer dimensions than we might think. New calculations show that this may not just be a mathematical trick, but a fundamental feature of space itself.
