Which galaxies are the poorest in gas and dust? Which galaxies have the fewest bright stars? Is it accurate to describe the physical universe as composed of only matter and energy? If most of the light travels through a material, the material is said to be what?
“The hunt for continuous gravitational waves is one of the top challenges in gravitational wave science,” said Andrew Melatos, an OzGrav Chief Investigator whose research group at the University of Melbourne has been chasing these tiny signals for more than a decade. “Pulsars ar...
black holes are even denser, but they are certainly far from normal. In fact, scientists believe that the strongest material in the Universe, referred to as “nuclear pasta,” can be found deep inside the crust ofneutron stars.
suggesting that the violent collisions of heavy ions at the LHC were smaller cousins of the Big Bang explosion that ushered in the visible universe some 14 billion years ago. Indeed, the conditions of the mini-fireballs at LHC resemble theearly universeas it was only microseconds...
