During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String ...

Under the conditions of the Hamiltonian principle, information is exchanged between two masses during an interaction by ...

As we contemplate the multiverse and explore the ideas in Michio Kaku’s new book, ‘The God Equation’, we realise that the ...

In the vast universe, galaxies rotate in ways that don’t make sense if only visible matter is considered. For almost a ...

All of this is calculated with the equations that underpin general relativity: Einstein's field equations. "The way that the space-time curves is determined by the Einstein field equations ...

Lieu focused on what’s known as the Poisson equation, a simplified form of Einstein’s field equations used for describing gravity in weaker fields, like those around galaxies. This equation ...

Cosmologist Katie Mack breaks down what the latest findings about dark energy mean for our universe’s future. Either way, it ...

If dark energy is weakening, it stands to reason that eventually gravity will become dominant and the universe will begin to ...

The field equations then give the correct dynamics for the electromagnetic field. When Albert Einstein formulated his theory of gravity, he used mathematics known as pseudo-Riemannian differential ...
