The total energy of the ball consists of its potential energy (related to position) plus its kinetic energy (related to motion). To zero out both components, you would have to give a precise value to ...

The loudest black hole collision ever recorded has just given Einstein’s theory of general relativity its hardest test so far. The event, dubbed GW250114, produced a record-smashing signal-to-noise ...

This year, ASC26 has attracted more than 300 student teams from universities and colleges across Chinese mainland, the United States, Germany, the United Kingdom, Singapore, Colombia, Brazil, ...

Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind. Now a series of discoveries and bold claims are turning that certainty into ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at once, described by a mathematical object called a wavefunction.

St Claire Scientific, Albuquerque, NM, USA. The structure of the paper is as follows. Section 2 reviews the curvature and action of the conformal metric and expresses the Einstein-Filbert functional ...

Researchers have discovered there was an anomaly in Earth's gravitational field between 2006 and 2008, potentially caused by a mineral shift deep within Earth's mantle. GRACE satellites detected a ...

FLORHAM PARK, N.J. — Once upon a time, Giants and Jets joint practices brought a little feistiness, the kind that saw Jeremy Shockey trying to take on half the Jets roster, and Tom Coughlin yelling at ...
