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....
In the equation, E = m c2, E stands for energy, m stands for an object’s mass, and c2 represents the speed of light (186,000 miles per second) multiplied by itself. Think of mass as simply the quantity of matter present. Energy is a tougher concept, but it is...
In spacetimes like these, no cosmic expansion is present. There’s no change in the distance or the light travel time between any points within this spacetime. With just one (or fewer) sources of matter inside and no other forms of energy, these “model...
