Hmm. Is there a fifth force of nature? And if so, does it explain or explain away 'dark' matter and 'dark' energy?

FYI: 'Physicists claim to have found NEW force of nature which may unravel one of the universe’s greatest MYSTERIES.'

Hmm. As our grand universe evolves, so too does our understanding of its nature...

FYI: 'The Simple Idea Behind Einstein’s Greatest Discoveries:
Lurking behind Einstein’s theory of gravity and our modern understanding of particle physics is the deceptively simple idea of symmetry. But physicists are beginning to question whether focusing on symmetry is still as productive as it once was.'

Hmm. Please ponder energy on the very small scales (Planck) to the very large scales (Neutron Stars, Black Holes, Galaxies, etc.)...
