Why does dark energy cause the universe’s expansion at the intergalactic level but not at the interstellar level? One problem is that many popular accounts make it appear that “space” is some substance expanding and dragging stuff along. THIS IS WRONG. Let me...
T The sheer magnitude of space is a source of endless fascination. The Milky Way alone is home to a staggering 200 to 400 billion stars, and when we consider the billions of galaxies that exist, the number of stars in space becomes genuinely unfathomable. The...

Mass is proportional to gravity because everything with mass emits tiny particles called gravitons. These gravitons are responsible for gravitational attraction. The more mass, the more gravitons. The properties of gravitons are thought to be responsible for the...
A neutron star merger is the stellar collision of neutron stars. When two neutron stars fall into mutual orbit, they gradually spiral inward. Neutron stars are the result of a massive star’s core collapsing under its own gravity during a supernova explosion....
