If the data holds up, this is one of the great scientific advances of all time: more indirect evidence of gravitational waves and more evidence that the universe may have inflated to near its present size in 10-45 seconds giving rise to what we understand to be the big bang.

  • What are electromagnetic waves?

Electromagnetic waves are waves in the electric and magnetic fields that are present everywhere in space.  Visible light is an electromagnetic wave, as are X-rays, radio waves, and microwaves; the only…
