Exploring quantum gravity and entanglement using pendulums

When it comes to a marriage with quantum theory, gravity is the lone holdout among the four fundamental forces in nature. The three others—the electromagnetic force, the weak force, which is responsible for radioactive ...

Unraveling the mystery of brown dwarfs

Brown dwarfs are astronomical objects with masses between those of planets and stars. The question of where exactly the limits of their mass lie remains a matter of debate, especially since their constitution is very similar ...

Roman Space Telescope will also find rogue black holes

In the past, we've reported about how the Roman Space Telescope is potentially going to be able to detect hundreds of thousands of exoplanets using a technique known as microlensing. Exoplanets won't be the only things it ...

How a ladybug warps space-time

Researchers at the University of Vienna and the Austrian Academy of Sciences, led by Markus Aspelmeyer have succeeded in measuring the gravitational field of a gold sphere, just 2 mm in diameter, using a highly sensitive ...

Factoring in gravitomagnetism could do away with dark matter

Observations of galactic rotation curves give one of the strongest lines of evidence pointing towards the existence of dark matter, a non-baryonic form of matter that makes up an estimated 85% of the matter in the observable ...

Researchers uncover key clues about the solar system's history

In a new paper published in the journal Nature Communications Earth and Environment, researchers at the University of Rochester were able to use magnetism to determine, for the first time, when carbonaceous chondrite asteroids—asteroids ...

Gaia: Most accurate data ever for nearly two billion stars

Today (3 December), an international team of astronomers announced the most detailed ever catalogue of the stars in a huge swathe of our Milky Way galaxy. The measurements of stellar positions, movement, brightness and colours are ...

Earth may have captured a stray 1960s-era rocket booster

Earth has captured a tiny object from its orbit around the sun and will keep it as a temporary satellite for a few months before it escapes back to a solar orbit. But the object is likely not an asteroid; it's probably the ...
